Confused on this one. I need someone to help me out.

The answer is 9.

We have been given that dimensions of original photo are 4 inches by 6 inches. We want the photo on the poster to be of dimensions 3 feet by 4 1/2 feet.            

First of all we will convert dimensions of poster from feet to inches.

Now, let us compare sides of our original photo with corresponding sides of poster.

Now, let us compare the second pair of corresponding sides.

We have seen that sides of poster are 9 times the sides of our original photo, therefore, the scale factor of this dilation is 9.      

Answer:

Plot the following points on the graph

[tex](-1, \frac{1}{2})[/tex], (0, 1), (1, 2), (2, 4), (3, 8)

Step-by-step explanation:

If the equation for the line is y = [tex]2^{x}[/tex], whatever the power/exponent  "x" equals, then y is equal to however many times 2 is multiplied by x.

For example, if our domain is {-1, 0, 1 , 2, 3}

then we would plug in each x value into the exponent to find the y-value in order to plot the points to solve the problem.

If x = -1, then y = 1/2. **If there is an a negative exponent it would get turned into a positive fraction with the denominator as the positive version of that number.

[tex]y = 2^{-1} = \frac{1}{2^{1} } = \frac{1}{2}[/tex]

If x = 0, then y = 1

**When the exponent is 0, the number automatically equals 1.

If x = 1, then y = 2.

If x = 2, then y = 4

If x = 3, then y = 8

So you would plot the following coordinates on the graph:

[tex](-1, \frac{1}{2})[/tex]

(0, 1)

(1, 2)

(2, 4)

(3, 8)

Answer: [tex]\frac{4}{5}[/tex]

Step-by-step explanation:

10 pens - 2 pens = 8 pens

Write 8 of 10 as a fraction.

You get [tex]\frac{8}{10}[/tex], right?

Now, simplify 8/10.

You get 4/5.

Step-by-step explanation:

When transforming radical expressions to rational exponents, the radicand (8) becomes the numerator of the rational exponent. And the index, or root (3) of the radical becomes the denominator of the rational exponent.

Answer: The first, second, and fourth is functions because every input has exactly one output.

The third and last ones is not functions.

Answer:

The first, third, and second are functions and the fourth and fifth are not a function

Step-by-step explanation:

Function meaning all the numbers in the y column are different so for an example 123 but if the numbers were 212 there are multiply of one number so that would not be a function

Answer:

9, 12, 13, 21

Step-by-step explanation:

let x be the third side, then

difference of 2 given sides < x < sum of 2 given sides , that is

15 - 10 < x < 15 + 10

5 < x < 25

The possible side lengths for the third side from the given list are

9, 12, 13, 21

Answer:

Domain: All real numbers

Range: y is greater than or equal to -5

Step-by-step explanation:

The domain is every possible x value. Because the function keeps going, it will be all real numbers.

The range is every possible y value. Because the function never goes below -5, y has to be greater than or equal to that.

Answer:

Stars are actually exploding when you see them, so the light is produced from the explosion.

Step-by-step explanation:

:)

Answer:  Stars shine because they are extremely hot (which is why fire gives off light — because it is hot). The source of their energy is nuclear reactions going on deep inside the stars.

Step-by-step explanation:

In most stars, like our sun, hydrogen is being converted into helium, a process that gives off energy that heats the star, this energy also causes the star to shine brightly.

Answer:

The amount of $1000 principal is needed to have $3000 after 5 years.

Step-by-step explanation:

As the interest formula is

[tex]I=Prt[/tex]

Where

Substituting the following values in the interest formula and solve for P

I=$3000

r = 6% = 6/100 = [tex]0.06[/tex]

t = 5

so the equation becomes

[tex]I=Prt[/tex]

[tex]3000=P\left(0.06\right)\left(5\right)[/tex]

switch both sides

[tex]P\left(0.06\right)\left(5\right)=3000[/tex]

[tex]P\left(0.3\right)=3000[/tex]

[tex]P=10000[/tex] $

Therefore, the amount of $1000 principal is needed to have $3000 after 5 years.

The answer is A. $5,783

Explanation:

= $4,500.00(1 + [0.019 * 15])

= $4,500.00(1 + 0.285)

= $4,500.00(1.285)

= $5,782.50

Round $5,782.50 to the nearest whole dollar and you get $5,783
