Part A: The average rate of change between the 2nd and 3rd point is Select a Value Part A: The average rate of change between th

Fofino [41]

Answer:

$Rate = 6$

$Rate = 10$

$Rate = 18$

$Rate = 162$

Step-by-step explanation:

Given

See attachment for table

Solving (a): Rate of change between 2nd and 3rd point on A

The rate of change is calculated as:

$Rate = \frac{y_2 - y_1}{x_2 - x_1}$

In table A, the 2nd and 3rd point is:

$(x_1,y_1) =(1,7)$

$(x_2,y_2) =(2,13)$

So, the average rate of change is:

$Rate = \frac{13 - 7}{2 - 1}$

$Rate = \frac{6}{1}$

$Rate = 6$

Solving (b): Rate of change between 3rd and 4th point on A

In table A, the 3rd and 4th point is:

$(x_1,y_1) =(2,13)$

$(x_2,y_2) =(3,23)$

So, the average rate of change is:

$Rate = \frac{23 - 13}{3 - 2}$

$Rate = \frac{10}{1}$

$Rate = 10$

Solving (c): Rate of change between 2nd and 3rd point on B

In table B, the 2nd and 3rd point is:

$(x_1,y_1) =(2,11)$

$(x_2,y_2) =(3,29)$

So, the average rate of change is:

$Rate = \frac{29 - 11}{3 - 2}$

$Rate = \frac{18}{1}$

$Rate = 18$

Solving (d): Rate of change between 4th and 5th point on B

In table B, the 4th and 5th point is:

$(x_1,y_1) =(4,83)$

$(x_2,y_2) =(5,245)$

So, the average rate of change is:

$Rate = \frac{245 - 83}{5 - 4}$

$Rate = \frac{162}{1}$

$Rate = 162$

8313.81=3000(1+r/12)^60 how do you get rid of the exponet

nika2105 [10]

Raise both sides to $\dfrac1{60}$ .

$8313.81=3000\left(1+\dfrac r{12}\right)^{60}$
$\implies8313.81^{1/60}=3000^{1/60}\left(\left(1+\dfrac r{12}\right)^{60}\right)^{1/60}$
$\implies1.162=1.143\left(1+\dfrac r{12}\right)$

$\implies r\approx0.1995$

If Sarah ate 1/4 of a small cupcake and Becky ate 1/4 of a big cupcake did they eat the same amount

tresset_1 [31]

No. 1/4 of a larger amount is more than 1/4 of a smaller amount.

Imagine the small cup cake weighs 4 ounces, and the large cup cake weighs 8 ounces.

1/4 of 4 ounces = 1/4 * 4 oz = 1 oz
1/4 of 8 ounces = 1/4 * 8 oz = 2 oz

1/4 of the larger cupcake is 2 ounces, whereas 1/4 of the smaller cupcake is 1 ounce.

Even though they both ate 1/4 of a whole thing, the one who ate 1/4 of the larger thing ate more.

Alchen [17]

In Y=-3x+5 the slope is: -3 and the Y intercept is 5.

Explanation:
The equation without any actual inputs is: Y=mX+B. m refers to the slope. B is the Y intercept. So when looking at the equation with information inputted. You would follow the same structure. Slope will be with the X and Y intercept will be added after.
