F(x) = -1/3x find the average rate of change of f from -2 to 2

1 answer:

8 0

Average rate=(change in y)/(change in x)

if f(x)=-x/3

r=( f(2)-f(-2) )/(2--2)

r=(-2/3-2/3)/(2+2)

r=(-4/3)/4

r=-4/12

r=-1/3

For a line, this is always true, since all lines have a constant velocity, the average velocity over any interval is equal to the slope.

34kurt

Answer: 59.49 meters
In this case, Gabriella flew 4 times with different distance. To answer this question you just need to add all the distance, The calculation would be:

Total distance = distance 1 + distance 2 + distance 3 + distance 4
Total distance = 8.05 meters+ 17.71 meters + 14.38 meters + 19.35 meters= 59.49 meters.

A = 1/2(a+x)h solve for x

ankoles [38]

For this case we have the following equation:

$A = \frac {1} {2} (a + x) * h$

We must clear the variable "x":

We multiply by 2 on both sides of the equation:

$2A = (a + x) * h$

We divide by h on both sides of the equation:

$\frac {2A} {h} = a + x$

We subtract "a" on both sides of the equation: $\frac {2A} {h} -a = x$

Answer: $x = \frac {2A} {h} -a$

Find the value of x and y in the diagram below.

xxTIMURxx [149]

Answer:

D) x=6√3, y=3√3

Step-by-step explanation:

Given both triangles are 30-60-90 triangles, this means that the length of y will be 9/√3=√81/√3=√(81/3)=√27=3√3

This also means that x will be twice the length of y which means x=2y=2(3√3)=6√3

This means that the correct answer is D) x=6√3, y=3√3

Refer to the diagram below to understand where I got these lengths.

Stells [14]

Hello there.

Question: In a cookie jar containing 6 chocolate chip cookies, 8 sugar cookies, and 10 peanut butter cookies, what is the probability that a person who isn’t looking as they pull out one cookie, will get a chocolate chip cookie?

Answer: First you need to calculate the total of cookies in the jar.
6 + 10 + 8 = 24.
There are 6 chocolate chip cookies.
Therefore the fraction is $\frac{6}{24}$
You can simplify it after that if you wish to.

In short, Your answer is $\frac{6}{24}$ .
In simplified form it would be $\frac{1}{4}$ .

Hope This Helps You!
Good Luck Studying ^-^
