Answer 1

Answer:

• arc PS = 40°

• arc UV = 24°

Step-by-step explanation:

There are relationships between the arcs intercepted by secant lines and the angle the secant lines make with each other. In these problems, you are expected to make use of these relationships, along with others you have learned about triangles.

The relationships are basically these:

• when the secants intersect inside the circle, the angle between them is half the sum of the intercepted arcs.

• when the secants intersect outside the circle, the angle between them is half the difference of the intercepted arcs.

__

First problem:

The angle between the secants QS and PR is shown to be 50°. Intercepted arc QR is shown to be 60°. You are asked to find the other intercepted arc, PS. Based on the above, we know ...

∠POS = (1/2)(arc PS + arc QR)

50° = (1/2)(arc PS + 60°)

Multiplying by 2, we get ...

100° = arc PS + 60°

Subtracting 60°, gives ...

40° = arc PS

__

Second problem:

We need to name a couple of points so we can describe more clearly what is going on. Call the point on arc PS where line QT intersects it point R. Call the point where line QT crosses line SU point X. (Point X is the vertex of the 99° angle.)

The relations described above tell us ...

angle W = (1/2)(arc PS - arc UV)

In this equation, we only know the value of arc PS = arc PR + arc RS = 20° + 94° = 114°.

But, we know two of the angles in triangle QWX. They are angle Q = 36° and angle X = 99°. Then angle W must be ...

angle W = 180° -36° -99° = 45°

Now, we can finish the above equation involving arc UV:

45° = (1/2)(arc PS - arc UV) . . . . . put the values we know in the secant relation

90° = 114° -arc UV

arc UV = 114° -90° = 24° . . . . . . . .solve for arc UV

Step-by-step explanation:

The directions tell you what you need to know. It is a matter of adding up the values shown and finding the missing number to make the total be -20. Of course, it works best to start with a row, column, or diagonal that has 4 numbers already.Then, you're only finding the 5th number.

You can start with either diagonal, column 1 or 4, and row 4 or 5. Filling the missing numbers in those spots (red) will let you find the remaining missing numbers (green, then blue).

The square at row 2, column 2 can be filled on the first round using the down-right diagonal. I have shown it as filled on the second round after row 5 column 2 is filled.

Using a spreadsheet can make this easier, because you can write formulas for the sums in each row, column, and diagonal. Then you're just making those sums be -20.

___

For example, consider the up-right diagonal. The sum of the given values, -6, 0, -4, -2, is -12. Then the spot at row 1, column 5 must be filled with -8 to make the sum be -20.

In order to inscribe a circle in a triangle, the circle's center must be placed at the incenter of the triangle.

This statement is true.

The INCENTER is the center of the circle that is inscribed in the triangle. Like the centroid, the incenter is always inside the triangle.

Step-by-step explanation:

If (x+2)^2+(y-5)^2=25 is the equation of a circle, which statement describes the circle's graph?

A) The center of the circle is (2,5), and the circle's radius is 25.

B) The center of the circle is (-2,5), and the circle's radius is 5.

C) The center of the circle is (2,-5), and the circle's radius is 5.

D) The center of the circle is (-2,-5), and the circle's radius is 5.

Answers

Answer:

B

Step-by-step explanation:

The standard form of a circle is

[tex](x-h)^2+(y-k)^2=r^2[/tex]

where h and k are the coordinates of the center of the circle and the radius is squared.  The radius is easy...take the square root of 25 to get that the radius is 5.  Since the pattern for the standard form is "x-" and "y-", if (x+2)^2 is the horizontal placement of the center, it actually was originally written as (x-(-2))^2, so the h coordinate is -2.  Same goes for the vertical movement of the center.  (y-(5))^2 means that the k coordinate is a positive 5.

The probabilities of drawing all hearts, face cards, or even cards are calculated with the formula: [tex](n/52) * ((n-1)/51) * ((n-2)/50)[/tex] where n is the total number of cards that match the desired outcome.

Explanation:

The subject here is probability, specifically, how to determine the likelihood of a particular outcome when drawing cards from a standard deck. Let's deal with each probability one at a time.

The probability that all the cards are hearts: There are 13 hearts in a deck of 52 cards. So the probability that the first card is a heart is 13/52, the second is 12/51 (because one heart is already drawn), and the third is 11/50. So, the overall probability is [tex](13/52) * (12/51) * (11/50).[/tex]The probability that all the cards are face cards: There are 12 face cards (kings, queens, and jacks) in a deck. Using the same principle, the probability is [tex](12/52) * (11/51) * (10/50).[/tex]The probability that all the cards are even: The 'even' cards are 2, 4, 6, 8, 10, which have 4 of each (hearts, diamonds, spades, clubs) totaling 20 cards. So, the probability is [tex](20/52) * (19/51) * (18/50).[/tex]

The number of customers at a new taco truck triples every day for a week. The function f(x) = 3^x represents the number of customers on day x. On what day was there 243 customers? Write an equation you need to solve it

Answers

Answer:

Day 5

Step-by-step explanation:

There are 2 ways to solve this, one using exponents and the other using logs. The equation regardless of how you solve it looks like this:

[tex]y=3^x[/tex]

where y is the number of customers on day x.  Filling in the number of customers we were given:

[tex]243=3^x[/tex]

There's a rule in exponents that says if the bases on both sides of the equals sign are like, then their exponents are equal to each other.  So if we can rewrite 243 in terms of a base of 3, then we're good.  I went to my calculator and started raising 3 to increasing powers of x:  3 to the first is 3; 3 squared is 9; 3 cubed is 27; 3 to the fourth is 81; 3 to the fifth is 243!  That means that

[tex]3^5=3^x[/tex]

Since the bases are like, then x = 5.

Using logs to solve it:

Take the log of both sides:

[tex]log(243)=log(3)^x[/tex]

There's a law of logs that says when you take the log of a number with an exponent, you can bring down the exponent in front like this:

[tex]log(243)=xlog(3)[/tex]

Now to solve for x, divide both sides by log(3):

[tex]\frac{log(243)}{log(3)}=x[/tex]

You can do that on your calculator and get that x = 5.

Whichever way is easier for you to understand OR whichever way your teacher is teaching according to where you are in your log unit, do it that way!  You can see that both give the same answer, the methods to get there vary.

Step-by-step explanation:

the perimeter of pentagon A is 15 in. Its area is 30 in^2. The perimeter of pentagon B is 25 in. What is the area of pentagon B assuming that these pentagons are similar

Answers

Answer:

The area of pentagon B is [tex]83\frac{1}{3}\ in^{2}[/tex]

Step-by-step explanation:

step 1

Find the scale factor

we know that

If two figures are similar, then the ratio of its perimeters is equal to the scale factor

Let

z-----> the scale factor

x----> perimeter pentagon B

y----> perimeter pentagon A

[tex]z=\frac{x}{y}[/tex]

substitute the values

[tex]z=\frac{25}{15}[/tex]

Simplify

[tex]z=\frac{5}{3}[/tex] ----> scale factor

step 2

Find the area of pentagon B

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z-----> the scale factor

x----> area pentagon B

y----> area pentagon A

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

we have

[tex]z=\frac{5}{3}[/tex]

[tex]y=30\ in^{2}[/tex]

substitute and solve for x

[tex](\frac{5}{3})^{2}=\frac{x}{30}[/tex]

[tex](\frac{25}{9})=\frac{x}{30}[/tex]

[tex]x=30*(\frac{25}{9})=83.33\ in^{2}[/tex]

convert to mixed number

[tex]83.33=83\frac{1}{3}\ in^{2}[/tex]

Final answer:

To find the area of pentagon B, we can use the fact that similar polygons have their corresponding sides proportional.

Explanation:

To find the area of pentagon B, we can use the fact that similar polygons have their corresponding sides proportional. If the perimeter of pentagon A is 15 in and the perimeter of pentagon B is 25 in, we can set up the proportion:

perimeter of pentagon B / perimeter of pentagon A = corresponding side lengths of pentagon B / corresponding side lengths of pentagon A

To find the corresponding side lengths of pentagon B, we can multiply the corresponding side lengths of pentagon A by the ratio of the perimeters:

corresponding side lengths of pentagon B = corresponding side lengths of pentagon A * (perimeter of pentagon B / perimeter of pentagon A)

Once we have the corresponding side lengths of pentagon B, we can use the formula for the area of a regular pentagon: Area = (1/4) * sqrt(5 * (5 + 2 * sqrt(5))) * s^2, where s is the length of a side. Calculate the area of pentagon B using the corresponding side lengths.

What is the surface area of a sphere with a radius of 16 units?

Answers

Answer:

D. 1024 π units²

Step-by-step explanation:

We have sphere, with a radius of 16 units.

The surface area of a sphere is given by the following formula:

Surface Area of a sphere = 4 π r²

We already know r, which is 16.  So,

SA = 4 * π * 16² = 256 * 4 * π  = 1024 π  units²

That's enough for our answer, which matches answer D from the list.

If we want to have an actual number.... we would have to multiply 1024 by π.

SA = 1024 * π = 3217 units²

Answer:

option D

1024π units²

Step-by-step explanation:

Given in the question that radius of a sphere = 16 unit

Formula to use to calculate the surface area of the sphere

4 π r²

here r is the radius of the sphere

4 π (16)²

4 π (256)

1024π units²

Surface area of a sphere with radius 16 units = 1024π units²

Equation of line in Two point form

When we know any two points on a line lets say [tex](a_1,b_1)[/tex] and [tex](a_2,b_2)[/tex], we can write its equation as:

[tex]y-b_1=m(x-a_1)[/tex]

where

[tex]m=\dfrac{b_2-a_2}{b_1-a_1}[/tex]

Here we have points of red line:( from graph) (0,3) and (6,0)

Equation of line: y-3=m(x-0)

m=0-3/6-0=-1/2

Equation:2y-6=-1(x)

               2y+x=6

Now from graph, we can see that the blue line is parallel to red line, therefore their slopes are same

The equation of blue line is as follows

y=mx+c

Point on blue line :(0,4)

4=(-1/2)*(0)+c

The mean is 25 and the standard deviation is 5.  So 20 is one standard deviation below the mean and 30 is one standard deviation above the mean.

According to the Empirical Rule, 68% of the normal curve is between ±1 standard deviations.  So the answer is 68%.

Answer:

The correct option is 2.

Step-by-step explanation:

Given information: The population mean is μ=25 and standard deviation is σ=5.

[tex]Z=\frac{X-\mu}{\sigma}=\frac{X-25}{5}[/tex]

We need to find the percent of the trees that are between 20 and 30 years old.

[tex]P(20<X<30)[/tex]

Subtract 25 from each side.

[tex]P(20-25<X-25<30-25)[/tex]

[tex]P(-5<X-25<5)[/tex]

Divide each side by 5.

[tex]P(-1<\frac{X-25}{5}<1)[/tex]

[tex]P(-1<Z<1)=P(Z<1)-P(Z<-1)[/tex]

Using standard normal table we get

[tex]P(-1<Z<1)=0.84134-0.15866=0.68268\approx 0.68=68\%[/tex]

68% of the trees are between 20 and 30 years old.

Therefore the correct option is 2.

Given expression is [tex]x^2-7x+c[/tex].

Now we need to find about what value for c will make the given expression [tex]x^2-7x+c[/tex], a perfect square trinominal.

Coefficient of middle term that contains x, in [tex]x^2-7x+c[/tex] -7.

Take half of that so we get [tex]-\frac{7}{2}[/tex].

Then take square of the half value.

We get [tex]\left(-\frac{7}{2}\right)^2=\frac{49}{4}[/tex].

We add the square value to make perfect square trinomial.

Hence final answer is [tex]\frac{49}{4}[/tex].

Answer:

D. [tex]\frac{49}{4}[/tex].

Step-by-step explanation:

We have been given a trinomial [tex]x^2-7x+c[/tex]. We are asked to find the value of c, which will make the expression a perfect square trinomial.

We know that a perfect trinomial is in form [tex]a^2\pm2ab+b^2[/tex].

We will use complete the square process to solve for c.

To complete a square, we need to add square of half the coefficient of x term. We can see that coefficient of x is -7, so the value of c would be:

[tex](\frac{b}{2})^2=(\frac{-7}{2})^2=\frac{(-7)^2}{2^2}=\frac{49}{4}[/tex].

Therefore, the value of c required to make the given expression a perfect trinomial is [tex]\frac{49}{4}[/tex] and option D is the correct choice.

Third choice is the one you want

Step-by-step explanation:

First off, we need to remember that for a line to be perpendicular to another line, its slope is the opposite reciprocal to the other line. The slope of our line is -1/4, so the opposite reciprocal slope is +4/1 or just 4. Now we know that m = 4.

The point-slope form of a line is

[tex]y-y_{1}=m(x-x_{1})[/tex]

where m is the slope, y1 is the y coordinate of the point, and x1 is the x coordinate of the point. Filling in:

[tex]y-5=4(x-(-3))[/tex] which simplifies to

[tex]y-5=4(x+3)[/tex] which simplifies further to

[tex]y-5=4x+12[/tex]

(x₂, y₂) → (6, 2)

Then the equation of the line will be

y - 4 = [(6 - 4) / (3 - 0)] (x - 0)

y - 4 = 2/3 x

    y = 2/3 x + 4

Then the correct option is D.

Given the equation, 3/(y - 5) = 15/(y + 4) what is the value of y?

Answers

Final answer:

To solve the equation 3/(y - 5) = 15/(y + 4) for the value of y, cross multiply to eliminate the fractions. Then collect the y terms on one side and the constant terms on the other side. Finally, divide both sides by the coefficient of y to find the value of y.

Explanation:

To solve the equation 3/(y - 5) = 15/(y + 4) for the value of y, we first cross multiply to eliminate the fractions.

This gives us 3(y + 4) = 15(y - 5). Expanding this equation, we have 3y + 12 = 15y - 75.

Next, we collect the y terms on one side and the constant terms on the other side. Simplifying the equation, we get 12 + 75 = 15y - 3y.

Combining like terms, we have 87 = 12y. Finally, we divide both sides of the equation by 12 to solve for y.

Therefore, the value of y is 7.25.
