Answer:

1. A

2. C

Step-by-step explanation:

H in the parent function equations are always negative and k is always positive.

Ex:

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

So that means when we're adding 4 to the exponent, we're actually subtracting, therefore moving the graph 4 units to the left.

Then, since k is positive, and we're adding 8, we move the graph 8 units up.

Answer:

$9.00

Step-by-step explanation:

4x + 12 = 48         - First, subtract 12 from each side of the equation.

4x = 36                 - Then, divide each side by 4 to get x by itself.

x = 9                     - After dividing by 4, we are left with x = 9, so 1 ticket costs

                              $9.00

For this case we have the following equation:

[tex]4x + 12 = 48[/tex]

Where the variable "x" represents the cost of a performance ticket.

Clear "x" of the equation to know the cost of a ticket.

Subtracting 12 on both sides of the equation:

[tex]4x = 48-12\\4x = 36[/tex]

Dividing between 4 on both sides of the equation:

[tex]x = \frac {36} {4}\\x = 9[/tex]

So, the cost of a ticket is $ 9.00

Answer:

Step-by-step explanation:

- 3 + 3x = 2x – 13

Bring -3 to the right side of the equation by adding 3 to both sides

(- 3 + 3) + 3x = 2x – 13 + 3

0 + 3x = 2x - 10

3x = 2x - 10

Bring 2x to the other side by subtracting 2x to both sides

3x - 2x = 2x - 2x - 10

x = -10

Check:

-3 + 3(-10) = 2(-10) - 13

-3 + (-30) = -20 - 13

-33 = -33

There are a few ways to do it; the easiest is just to follow the pattern of taking away two from the average.

The next lines of the table are

6 to 7  -13

7 to 8   -15

8 to 9   -17

Answer: C. -17

Let's find the equation and do it that way.

We have a vertex at (0,3) so we can fill out the vertex form a bit.  In general for vertex (p,q) it's

y = a(x-p)^2+q

We have

f(x) = ax^2 + 3

f(1) = 2

a+3 =2

a = -1

So we found our equation,

y = -x^2 + 3

Let's check it at x=5, y=-5^2+3=-25+3=-22, good

We want the rate of change from 8 to 9, which is

[tex]r = \dfrac{f(9)-f(8)}{9-8}=f(9)-f(8)=-9^2 - -8^2 = -17[/tex]

Answer: -17 again, that checks

The average rate of change for the interval from x=8 to x=9 is -17.

The correct option is (C)

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

We have a vertex at (0,3).

In general let us take vertex (p,q) then

y = a(x-p)²+q

We have,

f(x) = ax² + 3

as x=1, f(x)=2

so,

f(1) = 2

a+3 =2

a = -1

Now, the equation

y = -x² + 3

Thus, the rate of change from 8 to 9

= f(9)-f(8)/9-8

= -9²-(-8)²

=-81+64

=-17

Hence,  the average rate of change for the interval from x=8 to x=9 is -17.

Answer:

13 inches

Step-by-step explanation:

Your formula for a right circular cylinder's volume is

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

All you have to do is plug in your variables. Since we know that the volume is 2028pi and the height is 12 inches, we can set up the equation as follows:

[tex]2028\pi =\pi r^{2} 12[/tex]

Next, we simplify. First, we have to divide both sides by pi.

[tex]2028=12r^{2}[/tex]

Once we've divided both sides by pi, we can divide both sides by 12.

[tex]169=r^2[/tex]

Now, to find the radius, we have to find the square root of both sides. This is because the square root of r squared is r.

[tex]13=r[/tex]

Your radius is 13 inches.

In the context of Mathematics, it involves utilizing the volume formula of a right circular cylinder (V = πr²h) and rearranging it to solve for radius. Then, we substitute given values (volume and height of the cylinder) into the rearranged formula to calculate the value of the radius.

The subject of this question is Mathematics. Specifically, it involves using the formula for calculating the volume of a right circular cylinder to determine the radius when given the volume and height. The formula for the volume, V, of a right circular cylinder in terms of its radius, r, and its height, h, is V = πr²h.

To solve this problem, we need to rearrange the formula to solve for r which turns out to be r = √(V/(πh)). Substituting the given details, r becomes √(2028/(3.142*12)), which will give us the value of the radius. This involves use of algebra and geometry concepts.

Answer:

The standard deviation of the data set is 5.7 to the nearest tenth

Step-by-step explanation:

* Lets explain how to find the standard deviation

# Step 1: find the mean of the data set

∵ The mean = the sum of the data ÷ the number of the data

∵ The data set is 3 , 17 , 18 , 15 , 12 , 21 , 9

∵ Their sum = 3 + 17 + 18 + 15 + 12 + 21 + 9 = 95

∵ They are seven

∴ The mean = 95 ÷ 7 = 13.6

# Step 2: subtract the mean from each data and square the answer

∴ (3 - 13.6)² = 112.36

∴ (17 - 13.6)² = 11.56

∴ (18 - 13.6)² = 19.36

∴ (15 - 13.6)² = 1.96

∴ (12 - 13.6)² = 2.56

∴ (21 - 13.6)² = 54.76

∴ (9 - 13.6)² = 21.16

# Step 3: find the mean of these squared difference

∵ The mean = the sum of the data ÷ the number of the data

∵ The sum = 112.36 + 11.56 + 19.36 + 1.96 + 2.56 + 54.76 + 21.16 = 223.72

∴ The mean = 223.72 ÷ 7 = 31.96

# Step 4: the standard deviation is the square root of this mean

∴ The standard deviation = √(31.96) = 5.6533 ≅ 5.7

* The standard deviation of the data set is 5.7 to the nearest tenth

Answer:

y=-2x+14

Step-by-step explanation:

If we are looking for a line parallel to 2x+y=5.

Then we are looking for an equation with the same slope as the equation 2x+y=5.

To obtain the slope of equaiton 2x+y=5 I will put it in slope-intercept form.

Luckily there is only one step which is to subtract 2x on both sides.

y=-2x+5

The slope of this line is -2

The slope of parallel line will also be -2.

So we know our equation is in the form y=-2x+b

To find b we will just use the point (x,y)=(5,4) we know is on the line.

Plug in and solve for b.

4=-2(5)+b

4=-10+b

14=b

So the equation that is parallel to 2x+y=5 and goes through (5,4) is y=-2x+14

Answer:

Table B

we know that

A relationship between two variables, a, and b, represent a proportional variation if it can be expressed in the form [tex]b/a=k[/tex] or [tex]b=ka[/tex]

In this problem the table B shows a proportional relationship because

For a=20, b=25 -----> b/a=25/20=1.25

For a=24, b=30 -----> b/a=30/24=1.25

For a=32, b=40 -----> b/a=40/32=1.25

The constant of proportionality k is 1.25

Answer:

one solution: (2.5, 0)

Step-by-step explanation:

y = 2x – 5  

–8x – 4y = –20

Solve the second equation for y

Add 8x to each side

–8x+8x – 4y =8x –20

-4y = 8x-20

Divide by -4

-4y/-4 =8x/-4 -20/-4

y = -2x+5

The two equations are

y = 2x-5

y = -2x+5

Both equations are solved for y so set them equal

2x-5 = -2x+5

Add 2x to each side

2x+2x-5 = -2x+2x+5

4x-5 = 5

Add 5 to each side

4x-5+5 = 5+5

4x=10

Divide by 4

4x/4 = 10/4

x = 2.5

y = 2x-5

Substitute x=2.5 in

y = 2(2.5) - 5

y=5-5

It's the sum of the length of the sides used to make the given figure. The perimeter of Polygon A is 50 units.

It's the sum of the length of the sides used to make the given figure.

Given Polygon A is similar to polygon B. Also, The perimeter of polygon Ais 100.  Now, let the number of sides in Polygon A be n, while the length of a side is 2x. Therefore, the perimeter of the polygon A is,

n × 2x = 100

Given the length of the side of the polygon B is half the length of the side of polygon A. Therefore, the perimeter of polygon B is,

n × x = Perimeter

Now, if the ratio of the two equations is taken then,

(n × 2x)/ (n × x) = 100/ Perimeter

2 = 100/Perimeter

Perimeter = 50 units

Answer:

If two chords intersect each other in a circle, then the product of the segments of one chord equals the product of the segments of the other chord.

x² = 12

x = 2√3

The formula x = r0 is used to calculate the length of a circular arc 'x', given the radius 'r' and an angle '0' in radians. For example, for a radius of 0.15m and an angle of 75.4 radians, we find x = 11m.

The problem revolves around the relationship between the radius r and an angle in radians 0, given by the formula x = r0. This applies to questions involving the measurement of a circular arc, where 'x' is the length of the arc. An example calculation would be, if we had a radius of 0.15m and an angle of 75.4 radians, we would multiply these to find 'x', giving us x = 11m. Similarly, for a radius of 0.0450m and an angle of 220 radians, x = 9.90m. Notice that the unit of 'x' will always be in the same unit as the radius (in this case, meters).
