Answer:

[tex]y=-8.08[/tex] -------> [tex]y+8=3(x+2)^{2}[/tex]

[tex]y=14.25[/tex] -------> [tex]y-14=-(x-3)^{2}[/tex]

[tex]y=17.25[/tex] -------> [tex]y-17=-(x-3)^{2}[/tex]

[tex]y=-7.25[/tex] -------> [tex]y+7=(x-4)^{2}[/tex]

[tex]y=6.25[/tex] -------> [tex]y-6=-(x-1)^{2}[/tex]

Step-by-step explanation:  

we know that

The standard form of a vertical parabola is equal to

[tex](x-h)^{2}=4p(y- k)[/tex]

where

(h,k) is the vertex

the focus is (h, k + p)

and

the directrix is y = k - p

Part 1) we have

[tex]y+8=3(x+2)^{2}[/tex]

Convert to standard form

[tex](x+2)^{2}=(1/3)(y+8)[/tex]

The vertex is the point [tex](-2,-8)[/tex]

[tex]h=-2,k=-8[/tex]

[tex]4p=1/3[/tex]

[tex]p=1/12[/tex]

the directrix is equal to

[tex]y = k-p[/tex] -----> [tex]y=-8-(1/12)=-8.08[/tex]

Part 2) we have

[tex]y-14=-(x-3)^{2}[/tex]

Convert to standard form

[tex](x-3)^{2}=-(y-14)[/tex]

The vertex is the point [tex](3,14)[/tex]

[tex]h=3,k=14[/tex]

[tex]4p=-1[/tex]

[tex]p=-1/4[/tex]

the directrix is equal to

[tex]y = k-p[/tex] -----> [tex]y = 14-(-1/4)=14.25[/tex]

Part 3) we have

[tex]y+7.5=2(x+2.5)^{2}[/tex]

Convert to standard form

[tex](x+2.5)^{2}=(1/2)(y+7.5)[/tex]

The vertex is the point [tex](-2.5,-7.5)[/tex]

[tex]h=-2.5,k=-7.5[/tex]

[tex]4p=1/2[/tex]

[tex]p=1/8[/tex]

the directrix is equal to

[tex]y = k-p[/tex] -----> [tex]y=-7.5-(1/8)=-7.625[/tex]

Part 4) we have

[tex]y-17=-(x-3)^{2}[/tex]

Convert to standard form

[tex](x-3)^{2}=-(y-17)[/tex]

The vertex is the point [tex](3,17)[/tex]

[tex]h=3,k=17[/tex]

[tex]4p=-1[/tex]

[tex]p=-1/4[/tex]

the directrix is equal to

[tex]y = k-p[/tex] -----> [tex]y = 17-(-1/4)=17.25[/tex]

Part 5) we have

[tex]y+7=(x-4)^{2}[/tex]

Convert to standard form

[tex](x-4)^{2}=(y+7)[/tex]

The vertex is the point [tex](4,-7)[/tex]

[tex]h=4,k=-7[/tex]

[tex]4p=1[/tex]

[tex]p=1/4[/tex]

the directrix is equal to

[tex]y = k-p[/tex] -----> [tex]y=-7-(1/4)=-7.25[/tex]

Part 6) we have

[tex]y-6=-(x-1)^{2}[/tex]

Convert to standard form

[tex](x-1)^{2}=-(y-6)[/tex]

The vertex is the point [tex](1,6)[/tex]

[tex]h=1,k=6[/tex]

[tex]4p=-1[/tex]

[tex]p=-1/4[/tex]

the directrix is equal to

Answer 2
Final answer:

The parabolas represented by y + 8 = 3(x+2)², y - 14 = -(x-3)², y - 17 = -(x-3)², and y - 6 = -(x-1)² match with the directrixes y = -7.25, y = 14.25, y = 17.25, and y = 6.25 respectively.

Explanation:

To match the equations representing parabolas with their directrixes, we need to use the fact that the equation of a parabola is given by y - k = a(x-h)², where (h,k) is the vertex of the parabola and the directrix is given by y = k - 1/4a.

Given this, we can match the equations as follows:
1. y + 8 = 3(x+2)² matches with y = -7.25
2. y - 14 = -(x-3)² matches with y = 14.25
3. y + 7.5 = 2(x+2.5)² there isn't a match in column B
4. y - 17 = -(x-3)² matches with y = 17.25
5. y + 7 = (x-4)² there isn't a match in column B
6. y - 6 = -(x-1)² matches with y = 6.25.

Which binomial is equivalent to (xy + z)(xy − z)?

Answers

Final answer:

The binomial equivalent to (xy + z)(xy - z) is found by applying the difference of squares formula, resulting in x²y² - z².

Explanation:

The question asks which binomial is equivalent to the expression (xy + z)(xy - z). This can be simplified using the difference of squares formula, which is a² - b² = (a + b)(a - b). In this case, a is xy and b is z.

Applying the formula, we have:

First, square a: (xy)² = x²y²

Then, square b: z²

Subtract the square of b from the square of a to get the answer: x²y² - z²

Therefore, the binomial equivalent to (xy + z)(xy - z) is x²y² - z².

write the slope intercept inequality (0,2) (-1,-2)​

Answers

Hey there! :)

(0, 2) & (-1, -2)

Slope-intercept form is : y=mx+b , where m=slope, b=y-intercept

First, we must find the slope using the slope formula, which is :

m = y2-y1/x2-x1

Where y2 = -2 ; y1 = 2 ; x2 = -1 ; x1 = 0

Now, let's plug and chug! :)

m = (-2 - 2) / (-1 - 0)

Simplify.

m = -4/-1 --> Therefore, our slope is : m = 4

Now that we have the slope, we can plug this (and our original coordinates) into point-slope form, which is : y - y1 = m(x - x1) -> use the coordinates (0, 2)

y - 2 = 4(x - 0)

Simplify.

y - 2 = 4x

Add 2 to both sides.

y = 4x + 2

A manufacturer sells an item to an agency at a profit of 25%. The agency sells the item to a shopkeeper at 10% profit and shopkeeper sells the item at a profit of 20%. If the selling price of the item is $594, find the manufacturing price.

Answer: $360

Step-by-step explanation:

Let Mp the manufacturing price.

First step:

Manufacturer sells at a profit of 25% = Mp + Mp·0.25 = Mp·1.25

Second step:

Agency sells at a profit of 10% = 1.25Mp + 1.25Mp·0.10 = Mp·1.375

Third step:

Shopkeeper sells at a profit of 20% = 1.375Mp + 1.375Mp·0.20 = Mp·1.65

Then the final price = 1.65·Mp

1.65Mp = $594

Mp = $594/1.65 = $360 ►Manufacturer price

Answer: $360

Verification

Manufacturer sells at a profit of 25% = 25/100 = 0.25:

$360 + $360·0.25 = $360(1 + 0.25) = $360 + $90 = $450

Agency sells at a profit of 10% = 10/100 = 0.10:

$450 + $450·0.10 = $450(1 + 0.10) = $450 + $45 = $495

Shopkeeper sells at a profit of 20% = 20/100 = 0.20

$495 + $495·0.20 = $495(1 + 0.20) = $495 + $99 = $594 Checked!

Answers

Answer:

domain; x<0 or x>0

Step-by-step explanation:

We have been given the following function;

f(x) = 2x + 6/x^2 + 5x + 6

We need to evaluate the values of f(x) for the following domain values;

{-3, -2, 0, 2, 3}

f(-3) = 2(-3) + 6/(-3)^2 + 5(-3) + 6

      = -43/3

f(-2) = 2(-2) + 6/(-2)^2 + 5(-2) + 6

      = -6.5

f(0) = 2(0) + 6/(0)^2 + 5(0) + 6

     = undefined

f(2) = 2(2) + 6/(2)^2 + 5(2) + 6

     = 21.5

f(3) = 2(3) + 6/(3)^2 + 5(3) + 6

BC is tangent to circle A at point B. What is m2ACB if mZCAB = 22° ?

Answers

Answer:

68°

Step-by-step explanation:

We know that sum of 3 angles in a triangle is 180°.

In  ΔBAC, there are angles B, A, and C. Thus we can say:

B + A + C = 180

Since, BC is tangent to circle, the point of tangency, B is a 90 degree angle. So angle B is 90.

Also, given angle CAB is 22, which, in other word, is angle A is 22.

Thus, we can write:

B + A + C = 180

90 + 22 + C = 180

112 + C = 180

C = 180 - 112 = 68

Measure of angle ACB = 68°

The measure of angle ACB is 68°.

We know that sum of 3 angles in a triangle is 180°.

In  ΔBAC, there are angles B, A, and C. Thus we can say:

B + A + C = 180

Since, BC is tangent to circle, the point of tangency, B is a 90 degree angle. So angle B is 90.

Also, given angle CAB is 22, which, in other word, is angle A is 22.

Thus, we can write:

B + A + C = 180

90 + 22 + C = 180

112 + C = 180

C = 180 - 112 = 68

A pot of stew is placed on a stove to heat. The temperature of the liquid reaches 170°F, and then the pot is taken off the burner and placed on a kitchen counter. The temperature of the air in the kitchen is 76°F.

If k = 0.34, the temperature of the liquid after 7 hours will be

ºF. (Hint: Use Newton’s cooling model.)

Answers

Final answer:

To calculate the temperature of the liquid after 7 hours, you can use Newton's cooling model. By plugging in the initial temperature, the surrounding temperature, and the cooling constant into the equation T = T0 + (T1 - T0) * e(-kt), you can calculate the temperature after 7 hours. In this case, the temperature after 7 hours is approximately 152.85°F.

Explanation:

In this problem, we can use Newton's cooling model to determine the temperature of the liquid after 7 hours. Newton's cooling model states that the rate of heat loss or gain is directly proportional to the temperature difference between the object and its surroundings. Using the equation T = T0 + (T1 - T0) * e(-kt), where T is the temperature at time t, T0 is the initial temperature, T1 is the surrounding temperature, k is the cooling constant, and e is the base of the natural logarithm, we can calculate the temperature after 7 hours.

Convert the initial temperature, the surrounding temperature, and the time to Kelvin.

Plug the values into the equation and calculate the temperature after 7 hours.

Using the given values of T0 = 170°F, T1 = 76°F, and k = 0.34, we can calculate the temperature after 7 hours.

T0 = 170°F + 459.67 = 629.67 K

T1 = 76°F + 459.67 = 535.67 K

T = 629.67 + (535.67 - 629.67) * e⁻°³⁴*⁷

T ≈ 152.85°F

Answer:

b) There is translation 3 units to the right and 1 unit up

c) The domain is {x I x > 3}

   The equation of the asymptote is x = 3

Step-by-step explanation:

* Lets revise the rule of the translation

- If the function f(x) translated horizontally to the right  

 by h units, then the new function g(x) = f(x - h)

- If the function f(x) translated horizontally to the left  

 by h units, then the new function g(x) = f(x + h)

- If the function f(x) translated vertically up  

 by k units, then the new function g(x) = f(x) + k

- If the function f(x) translated vertically down  

 by k units, then the new function g(x) = f(x) – k

* Now lets solve the problem

b) ∵ f(x) = [tex]log_{2} (x-3)+1[/tex]

∵ The parent function is [tex]log_{2} x[/tex]

∴ x is changed to (x - 3), that means there is a translation 3 units

  to the right

∵ We add the parent function by 1, that means there is a translation

  1 unit up

* There is translation 3 units to the right and 1 unit up

c) To find the domain of the function, find the values of x which

    make the function undefined

∵ [tex]log_{2}(0)[/tex] is undefined

∴ x - 3 can not be 0

∵ x - 3 = 0 ⇒ add 3 to both sides

∴ x = 3

∴ The domain of the function is all real number greater than 3

* The domain is {x I x > 3}

∵ x can not be 3

∴ There is a vertical asymptote, its equation is x = 3

* The equation of the asymptote is x = 3

What is 5x=45 then x=

Answers

5x=45

divide by 5 for 5x and 45 to get the answer

5x/5= 45/5

x=9 ( Answer)

The solution to the equation 5x = 45 is x = 9.

To solve the equation 5x = 45, you want to find the value of x that satisfies the equation.

Here's how you can solve it step by step:

Step 1: Start with the equation 5x = 45.

Step 2: To isolate x, divide both sides of the equation by 5. This step cancels out the multiplication by 5 on the left side of the equation.

(5x) / 5 = 45 / 5

Simplifying further:

x = 9

Explanation: In Step 2, when you divide both sides of the equation by 5, you are essentially undoing the multiplication operation on the left side.

By dividing both sides by the same number, you maintain the equality of the equation.

On the left side, the 5s cancel out, leaving you with just x. On the right side, 45 divided by 5 equals 9.

Thus, x = 9 is the value that satisfies the equation.

Therefore, the solution to the equation 5x = 45 is x = 9.

[tex](-\infty,-2)\cup (-2,2)\cup (2,+\infty)[/tex]

Step-by-step explanation:

The given rational expression is:

[tex]y=\frac{2x-4}{x^2-4}[/tex]

We factor this expression to obtain:

[tex]y=\frac{2(x-2)}{(x-2)(x+2)}[/tex]

We can see that, this rational function has a hole at x=2 and a vertical asymptote at x=-2

Therefore the domain is

[tex]x\ne 2\: and\:x\ne -2[/tex]

Or

[tex](-\infty,-2)\cup (-2,2)\cup (2,+\infty)[/tex]

The circumference of the circle with a diameter of 16 units is approximately 50.26544 units.

To find the circumference of a circle, you can use the formula C = πd, where C represents the circumference and d is the diameter of the circle. In this case, the diameter of the circle is given as 16 units.

Substituting the value into the formula, we have C = π(16). Using the value of π (pi) as approximately 3.14159, we can calculate the circumference.

C = 3.14159 x 16 = 50.26544 units.

Therefore, the circumference of the circle with a diameter of 16 units is approximately 50.26544 units.

You select a card from a standard shuffled deck of 52 cards. Without replacing, you select another card. Find the probability that you select a black card, then a red card.

Answers

In a standard shuffled deck of 52 cards, half of the cards are black and half of the cards are red: (26 black cards, 26 red cards).

Since we are interested in pulling a black card first, the probability is 26/52.

Without replacing the card we have chosen, we are left with 51 total cards in the entire deck (25 black cards, 26 red cards).

Now that we want to pull a red card, we know that the probability will be 26/51.

Since we are interested in both events occurring simultaneously, we must multiply the probability of the first by the probability of the second, aka: (26/52) * (26/51)

The answer we are given is 0.2549

The probability of picking a black card and then a red card from a standard deck without replacement is 13/51.

To calculate the probability of selecting a black card and then a red card from a standard deck without replacement, we need to consider the sequence of the two events. Initially, the deck contains 26 black cards (spades and clubs) and 26 red cards (diamonds and hearts). The probability P(A) of picking a black card first is 26/52 or 1/2.

After one black card has been removed, there are now 51 cards left in the deck with 26 red cards remaining. The probability P(B) of then picking a red card is 26/51. To find the overall probability of both events happening in sequence, we multiply the probabilities:

[tex]P(A and B) = P(A) \times P(B) = (\frac{1}{2}) \times (\frac{26}{51})[/tex]

This simplifies to P(A and B) = [tex](\frac{26}{102})[/tex] which can be further simplified to [tex](\frac{13}{51}).[/tex]

Determine whether the function f(x) = -2x - 5x is even, odd, or neither.

Answers

Answer: odd

Step-by-step explanation:

A function is even if for any input value x and -x there is the same output value y. In other words, a function is even if:

[tex]f (-x) = f (x)[/tex]

A function is odd if it is true that:

[tex]f (-x) = -f (x)[/tex]

Then we must test if [tex]f(-x) = f(x)[/tex] for the function: [tex]f(x)=-2x - 5x[/tex]

[tex]f(-x)=-2(-x) - 5(-x)[/tex]

[tex]f(-x)=2x + 5x[/tex]

So [tex]f(-x) \neq f(x)[/tex]

The function is not even

Now we must test if [tex]f (-x) = -f (x)[/tex] for the function.

[tex]f(-x)=-2(-x) - 5(-x)[/tex]

[tex]f(-x)=2x + 5x[/tex]

[tex]f(-x)=-(-2x -5x)[/tex]  and  [tex]f(x)=-2x - 5x[/tex]

So [tex]f(-x) = -f(x)[/tex]  

Finally the function is odd

If f(x) = 4x + 5, which of these is the inverse of f(x)?​

Answers

Answer:

A

Step-by-step explanation:

y=4x+5

x=4y+5

4y+5=x

4y+5-5=x-5

4y=x-5

4y/4= x/4 - 5/4

y= x-5/4

Final answer:

To find the inverse of the function f(x) = 4x + 5, switch x and y in the equation, then solve for y to get the inverse function, which is f-1(x) = (x - 5) / 4.

Explanation:

To find the inverse of the function f(x) = 4x + 5, you would follow these steps:

Replace f(x) with y: y = 4x + 5.Switch the roles of x and y: x = 4y + 5.Solve the equation for y to find the inverse function:Subtract 5 from both sides: x - 5 = 4y.Divide by 4: y = (x - 5) / 4.The inverse function is: f-1(x) = (x - 5) / 4.

This inverse function will satisfy the condition that f(f-1(x)) = x and f-1(f(x)) = x, which is the defining property of an inverse function.

Answers

Answer:

B

Step-by-step explanation:

V=4/3 x 3.14 x 3^3

V= 113.04

SA= 4 x 3.14 x 3^2

SA= 113.04

Answer:

The answer is V=SA

Step-by-step explanation:

V=4/3 x 3.14 x 3^3

V= 113.04

SA= 4 x 3.14 x 3^2

SA= 113.04

So the relationship should be V=SA, because the equaled amount on both ends was the same.
