Answer:

1. -1/28

2. -4

3.A) The attendance increased by an average of 25 people per game from game 2 to game 5.

4. -.125

Step-by-step explanation:

To find the rate of change, we use the formula

f(x2) - f(x1)

--------------

x2-x1

f(x) = -(x) ^ 1/3

f(64) = -(64) ^ 1/3 = -4

f(8) =- (8)^1/3 = -2

f(64) - f(8) -4--2 -4+2 -2 -1

-------------- = --------- = ------------- = ----------- = ------

64 - 8 56 56 56 28

f(2) = 9

f(-2) = 25

f(x2) - f(x1) f(2) - f(-2) 9-25 -16 -16

-------------- =----------- = ----------------- = ---------- = ----------- = -4

x2-x1 2--2 2+2 4 4

f(5) = 755

f(2) = 680

f(x2) - f(x1) f(5) - f(2) 755-680 75

-------------- = ---------- = -------------- = ---------- = 25

x2-x1 5-2 3 3

A) The attendance increased by an average of 25 people per game from game 2 to game 5.

f(-1) = -.25

f(1) = -.5

f(x2) - f(x1) f(1) - f(-1) -.5 --.25 -.5+.25 -.25

-------------- = ---------- = -------------- = ---------- = --------- = -.125

x2-x1 1--1 1+1 2 2

Rounded to the nearest hundred cubic meters, what is the total capacity (cone and cylinder) of the storage container?

hichkok12 [17]

The picture in the attached figure

we know that
the total capacity of the storage container=volume of a cone+volume of cylinder

step 1
find the volume of a cone
volume of a cone=(1/3)*pi*r²*h
r=6 m
h=8 m
so
volume=(1/3)*pi*6²*8-----> 301.44 m³

step 2
find the volume of the cylinder
volume of a cylinder=pi*r²*h
r=6 m
h=10 m
s6
volume=pi*6²*10----> 1130.40 m³

total volume=301.44+1130.4-----> 1431.84 m³-------> 1400 m³

the answer is
1400 m³

Jin needs 0.8 gram of carbon for an experiment. She needs 4.15 times as much water. Jins says that she needs less than 4.15 gram

natima [27]

Answer:

That is a correct statement.

Step-by-step explanation:

This is because to find the appropriate amount, we would multiply the two numbers together. Since we are multiplying 4.15 by a number less than 1 (0.8), the number can only be lower. The number would only be higher if the number was greater than 1.
