Step-by-step explanation:

Divide through by 2

2a² - 5a + 3 = 0

To factor the quadratic

Consider the factors of the product of the coefficient of the a² term and the constant term which sum to give the coefficient of the x- term

product = 2 × 3 = 6 and sum = - 5

The factors are - 2 and - 3

Use the factors to split the a- term

2a² - 2a - 3a + 3 = 0 ( factor the first/second and third/fourth terms )

2a(a - 1) - 3(a - 1) = 0 ← factor out (a - 1)

(a - 1)(2a - 3) = 0

Equate each factor to zero and solve for a

a - 1 = 0 ⇒ a = 1

2a - 3 = 0 ⇒ 2a = 3 ⇒ a = [tex]\frac{3}{2}[/tex]

Answer:

a = 3/2 or 1

Step-by-step explanation:

4a²-10a+6=0

(Divide by 2)

2a²-5a+3=0

(Now factorise)

(2a-3)(a-1)

a = 3/2 or 1

If Q=2.1(R)+5, then it would be 2.1(5)+5=15.5 ?

Step-by-step explanation:

3/4 *40 =30.

So 30 cars have in state license

To find how many cars have in-state license plates, multiply the total number of cars (40) by the fraction (3/4). The answer is 30 cars have in-state license plates.

To find the number of cars with in-state license plates, we need to calculate 3/4 of the total number of cars in the parking lot.

Therefore, 30 cars in the parking lot have in-state license plates.

Correct question :

The parking lot has 40 cars and 3/4 of the cars have in-state license plates. How many cars have in-state license plates?

Answer:

Part A) The cone couldn't contain all the ice cream if it melted.

Part B) The height of the cone would be [tex]8\ cm[/tex]

Part C) The height of the cylinder would be [tex]3\ cm[/tex]

Step-by-step explanation:

Part A) Determine whether the cone could contain all of the ice cream if it melted

step 1

Find the volume of the ice cream (sphere)

The volume is equal to

[tex]V=\frac{4}{3}\pi r^{3}[/tex]

we have

[tex]r=4/2=2\ cm[/tex] -----> the radius is half the diameter

substitute

[tex]V=\frac{4}{3}\pi (2)^{3}=\frac{32}{3}\pi\ cm^{3}[/tex]

step 2

Find the volume of the cone

The volume is equal to

[tex]V=\frac{1}{3}\pi r^{2}h[/tex]

we have

[tex]r=4/2=2\ cm[/tex] -----> the radius is half the diameter

[tex]h=7.5\ cm[/tex]

substitute

[tex]V=\frac{1}{3}\pi (2)^{2}(7.5)=\frac{30}{3}\pi\ cm^{3}[/tex]

step 3

Compare the volume of the sphere and the volume of the cone

[tex]\frac{30}{3}\pi\ cm^{3} < \frac{32}{3}\pi\ cm^{3}[/tex]

The volume of the cone is less than the volume of the sphere

therefore

The cone couldn't contain all the ice cream if it melted.

Part B) What would be the smallest cone in height in whole centimeters that would allow the cone to contain all of the melted ice cream if the diameter of the cone remains unchanged

The volume of the cone is equal to

[tex]V=\frac{1}{3}\pi r^{2}h[/tex]

we have

[tex]V=\frac{32}{3}\pi\ cm^{3}[/tex]

[tex]r=2\ cm[/tex]

substitute in the formula and solve for h

[tex]\frac{32}{3}\pi=\frac{1}{3}\pi (2)^{2}h[/tex]

simplify

[tex]32=(2)^{2}h[/tex]

[tex]32=4h[/tex]

[tex]h=32/4=8\ cm[/tex]

Part C) If the container of the ice cream changed to a cylinder as shown in the diagram below, what would be the smallest height of the cylinder needed to the nearest whole centimeter to contain the melted ice cream

The volume of the cylinder is equal to

[tex]V=\pi r^{2}h[/tex]

we have

[tex]V=\frac{32}{3}\pi\ cm^{3}[/tex]

[tex]r=2\ cm[/tex]

substitute in the formula and solve for h

[tex]\frac{32}{3}\pi=\pi (2)^{2}h[/tex]

simplify

[tex]\frac{32}{3}=(2)^{2}h[/tex]

[tex]\frac{32}{3}=4h[/tex]

[tex]h=\frac{32}{12}=2.67\ cm[/tex]

Round to the nearest whole centimeter

Answer:

Step-by-step explanation:

Let L and W represent the length and width of the field. Then the perimeter is given by ...

  P = 2(L +W)

Filling in the given information, we have ...

  320 = 2(L +W)

  L = W +48 . . . . . . the length is 48 ft longer than the width

Using the second equation in the first, we get

  320 = 2((W +48) +W)

  320 = 4W +96 . . . . . . simplify

  224 = 4W . . . . . . . . . . subtract 96

  56 = W . . . . . . . . . . . . .divide by 4

  L = 56 +48 = 104 . . . . find L using the above relation

The width of the field is 56 ft; the length is 104 ft.

The width of the playing field is 56 ft and the length is 104 ft.

To solve this problem, let's set up an equation using the information given. Let's say the width of the field is x ft. Since the length is 48 ft longer than the width, the length can be represented as x + 48 ft. The formula for the perimeter of a rectangle is P = 2(l + w), so we can set up the equation: 320 = 2(x + 48 + x). Now, we can solve for x by simplifying and solving the equation.

320 = 2(2x + 48)

320 = 4x + 96

4x = 320 - 96

4x = 224

x = 224/4

x = 56

So, the width of the field is 56 ft and the length is 56 + 48 = 104 ft.

To solve this problem, we must use the formula for the perimeter of a rectangle, which is P = 2L + 2W, where P is the perimeter, L is the length, and W is the width.

According to the question, the length is 48 ft longer than the width, therefore we could express the length as L = W + 48. The perimeter provided is 320 ft. Now we can plug these values into the perimeter formula.

320 = 2(W + 48) + 2W

After simplification, this formula becomes 320 = 4W + 96.

To isolate W, you subtract 96 from both sides to get: 320 - 96 = 4W + 96 - 96, which simplifies to 224 = 4W. Dividing both sides by 4 gives W = 56 ft. This is the width of the field. The length, then, is 56 ft + 48 ft = 104 ft (since the length is 48 ft longer than the width).

So, the dimensions of the field are 104 feet by 56 feet

Answer: 275%

Step-by-step explanation:

Given : The current weight of the puppy : 2,250 grams

The weight of the puppy at the last visit = 600 grams

Increase in weight :-

[tex]2250\text{ grams}-600\text{ grams}=1650\text{ grams}[/tex]

Now, the formula to calculate the percentage increase is given by :-

[tex]\dfrac{\text{Increase in quantity}}{\text{Previous quantity}}\times100[/tex]

The percentage increase in weight is given by :-

[tex]\dfrac{1650}{600}\times100=275\%[/tex]

Hence, the percent increase in the puppy's weight  = 275 %.

a. 3u + 2v

To solve this problem, we need to apply some properties of logarithms. Properties are useful to simplify complicated expressions. Here we need to use a very useful property of logarithms called  the logarithm of a product is the sum of the logarithms, that is:

[tex]log_{b}(MN)=log_{b}(M)+log_{b}(N)[/tex]

From the function, it is then true that:

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

The other property we must use is Logarithm of a Power:

[tex]log_{b}M^{n}=nlog_{b}M[/tex]

Then:

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

Since:

[tex]u=ln(x) \\ v=ln(y)[/tex]

Then:

[tex]ln(x^{3}y^{2})=3u+2v[/tex]

Exponential Function

Step-by-step explanation:

The y-axis represents the number of Bacteria and x-axis represents the number of hours. If you observe closely you will see that the number of bacteria are doubling after each hour. For example, at time = 4 hours the number of Bacteria were about 50, at time = 5 hours the number of Bacteria were about 100 and at time = 6 hours the number of Bacteria increased to about 200.

This type of behavior is a property of exponential functions where we see a multiplicative rate of change in the values i.e. each value is a multiple of previous value. A rough model for this function would be:

[tex]f(x)=f(0)(2)^{x}[/tex]

Where, f(0) represents the number of bacteria at time = 0 hours i.e. number of Bacteria initially present and "x" represents the number of hours.

Final answer:

To find the percent of decrease, calculate the difference between the original and final numbers, divide by the original number, and multiply by 100. In this case, the percent of decrease is 25%.

Explanation:

To find the percent of decrease from the original number to the final number, we need to calculate the difference between the original number and the final number, then divide that difference by the original number and multiply by 100 to get the percentage.

Let's assume the original number is x. When the number is increased by 50%, it becomes 1.5x. When the result is decreased by 50%, it becomes 0.5 times 1.5x, which is 0.75x.

The decrease from the original number to the final number is x - 0.75x = 0.25x. To find the percent of decrease, we divide the decrease by the original number (0.25x / x) and multiply by 100 to get 25%. Therefore, the percent of decrease from the original number to the final number is 25%.

Final answer:

The overall percent change from the original number to the final number, after increasing by 50% and then decreasing by 50%, is a 25% decrease.

Explanation:

To find the percentage decrease from the original number to the final one after the series of increases and decreases described, we need to follow a couple of steps:

First, we increase the original number by 50%. If the original number is x, its increased value is x + 0.5x = 1.5x.

Next, we decrease this new number by 50%. The decreased value is 1.5x - (0.5 × 1.5x) = 1.5x - 0.75x = 0.75x.

To find the percentage change from the original value, we calculate (final value - initial value) / initial value × 100%. Using the value obtained from the second step, this becomes (0.75x - x) / x × 100% = -0.25x/x × 100% = -25%.

Therefore, the overall percent change is a 25% decrease from the original number.

Answer:

(x,y) = (0,-8)

Step-by-step explanation:

We know that a point in polar coordinates is represented by

(r, θ)

Where r is the distance from the origin and θ is the angle.

Rectangular coordinates can be found by

x = r*cos(θ)

y = r*sin (θ)

x = r*cos(θ) = 8* cos (3π/2)

y = r*sin (θ) = 8 sin(3π/2)

x = 8* cos (3π/2) = 8*0 = 0

y = 8* sin (3π/2) = 8*(-1) = -8

(x,y) = (0,-8)

Correct option is (A) (0,-8)

Now any point in polar coordinates is represented by

(r, θ)

where 'r' is the distance from the origin

and 'α' is the angle.

Rectangular coordinates can be found by using the formula:

[tex]x=r*cos(\alpha )\\y=r*sin(\alpha )[/tex]

Thus the x coordinate would be given as :

[tex]x=r*cos(\alpha )\\x=8*cos(\frac{3\pi }{2} )\\x=8*0\\x=0\\[/tex]

Similarly the y coordinate would be given as :

[tex]y=r*sin(\alpha )\\y=8*sin(\frac{3\pi }{2} )\\y=8*(-1)\\y=-8\\[/tex]

Thus (x, y) = (0,-8) is the required coordinates

Answer:A prime number is a whole number greater than one whose only factors are 1 and itself

Answer:

B

Step-by-step explanation:

We know:

1. Replacing -x into x of an equations reflects the graph on the y-axis

2. If f(x) is a function, then f(x)+a is a vertically translated graph of the original graph, a units up

Looking at the original function of ln x and the transformed graph of ln(-x) +5, we see that we have replaced x with -x, which means it is a reflection across the y-axis.

Also, we have added a five after the function, so that means it is a vertical translation of 5 units up.

Looking at the answer choices, we see that B is the correct answer.

The length of the missing side is √445 meters.

For a right triangle, the Pythagorean theorem states that the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides (the legs).

In this case, we are given the lengths of the two legs, which are 11 meters and 18 meters. We need to find the length of the hypotenuse, which is the missing side.

Steps to solve:

Step 1: Substitute the given values into the Pythagorean theorem:

[tex]a^2 + b^2 = c^2[/tex]

where:

a = 11 meters (shorter leg)

b = 18 meters (longer leg)

c = the missing side (hypotenuse)

Step 2: Evaluate the equation:

[tex]11^2 + 18^2[/tex]= [tex]c^2[/tex]

121 + 324 = [tex]c^2[/tex]

445 = [tex]c^2[/tex]

Step 3: Take the square root of both sides to solve for c:

c = √445

The length of the missing side is √445 meters

Answer:

it took a total of 260 minutes or 4 hours and 20 minutes from Collin's house to his hotel.

Step-by-step explanation:

As each of the activities described is an independent activity that does not overlap, we can easily sum up the durations of each to find the total time Collin took from his house to the hotel.

We add it as follows :

he drove to the airport for 45 minutes + he waited at the airport for the flight to depart for 90 minutes + his fight duration was 70 minutes + upon landing, he gathered his luggage for 20 minutes + he drove to the hotel for 35 minutes.

Just got this quiz question right.

Hope this helps :)

For this question we need to use the Pythagorean Theorem (a2+b2=c2) since the rectangle is being divided into two triangles.

we know the length of the triangle (63) and we know the hypotenuse (65) but not the width. To find the width, we can plug the values we know into our formula.

(63) squared + b squared = (65) squared

solve.

3969 + b squared = 4225

subtract 3969 from both sides.

b squared = 256

√b² = √256

b=16

the correct answer would be 46°
