The average rate of change of a linear function is the slope of the line. Since we are given the following coordinates:
(0,150) and (3,0)
We can easily solve for the slope.
m = (y2 - y1) / (x2 - x1)
m = (0 - 150) / (3 - 0) = -50

Therefore, the average rate of change of the function in the three seconds is -50.

After Myong's cylindrical birthday cake was sliced, she received the slice at right. If her birthday cake originally

Talja [164]

Answer:

97.53 in³

Step-by-step explanation:

The cylindrical birthday cake has a diameter (d) of 14 inches and a height (h) of 6 inches.

The radius of the cake (r) = diameter / 2 = 14 inches / 2 = 7 inches.

The volume of the full cake = πr²h = π(7²)6 = 924 in³

Since only a part of the cake was cut and given to Myong. The total measure of the cake is 360°, but the part given to her was 38°. Hence the volume of her slice is given as:

Volume of her slice = (38 / 360) * volume of the full cake = (38 / 360) * 924 = 97.53 in³

Volume of her slice = 97.53 in³

How to get rid of fraction exponents?. for example: x^(1/2)

Komok [63]

Remember
$x^{ \frac{m}{n} }= \sqrt[n]{x^m}$

so
$x^{ \frac{1}{2} }= \sqrt[2]{x^1}$ or √x

A manufacturer made 7,234 boxes of coffee stirrers.Each box contians 1000 stirrers.How many stirrers did they make?

mash [69]

To answer this, you multiple 1000 by 7,234 because each box comes with 1000, so if there are 7234 boxes, then you multiple the stirrers by the # of boxes
