Enter the difference between the rates of change for these two functions.

Alchen [17]

Answer:

.

Step-by-step explanation:

Graph :

Choose any two points. (0 , 2) and (-1 , -2)

Rate of change = Change in y ÷ Change in x

$= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\= \frac{-2 - 2}{-1 - 0}\\\\= \frac{-4}{-1}\\\\= 4$

Table:

Rate of change = $\frac{-2-[-6]}{2-0}$

$= \frac{-2+6}{2}\\\\= \frac{4}{2}\\\\= 2$

I NEED HELP ASAP PLEASE

Ahat [919]

Answer: Domain: 0,1,2,3 and 4 and Range: 1,2,4,8 and 4

Step-by-step explanation:

The domain is the set of all inputs that makes the function definable. As we see the function looks like an exponential function which means the domain is all real numbers.

So the inputs are 0,1,2,3 and 4

the outputs are 1,2,4,8 and 4

How find a ratio of the area of a circle and a square

ladessa [460]

Answer:

<u>CIRCLE : CIRCLE</u>

Ratio of area is the scale factor squared. So find the radii of the two circles, square both values, and simplify the ratio.

<u>SQUARE : SQUARE</u>

Ratio of area is the scale factor squared, So find the side lengths of the two squares, square both values, and simplify the ratio.

<u>SQUARE : CIRCLE</u>

Using the formulas A = s*s and A = pi*r^2, find the areas of the circle and the square. Then simplify the ratio.

Yasmine has 4 containers of 4 different colors of flowers to plant. She had 1/3 of each color left over when she was done planti

olga2289 [7]

Answer:

$2\frac{2}{3}$

Step-by-step explanation:

Given the information

4 containers of 4 different colors
1/3 of each color left over
She had planted more than 2 1/2 of the original 4 containers

=> Total color were left = 1/3 x 4 = 4/3 of the original containers

=> Total color were planted = (1 - 1/3) x 4 = 2/3 x 4 = 8/3 of the original containers

However, 8/3 = $2\frac{2}{3}$ > 2 $\frac{1}{2}$

So she is true, hence, the fractions to determine the total amount of containers of flowers she planted is: $2\frac{2}{3}$

Hope it will find you well
