Answer: (-2, -5), (-1, -8), (0, -9), (1, -8), (2, -5)

Step-by-step explanation:

f(-2)=(-2)^2-9

f(-2)=4-9

f(-2)=-5 ==> (-2, -5)

f(-1)=(-1)^2-9

f(-1)=1-9

f(-1)=-8 ==> (-1, -8)

f(0)=0^2-9

f(0)=0-9

f(0)=-9 ==> (0, -9)

f(1)=(1)^2-9

f(1)=1-9

f(1)=-8 ==> (1, -8)

f(2)=(2)^2-9

f(2)=4-9

f(2)=-5 ==> (2, -5)

I made a fort for my pet porcupine by connecting two boxes. the first box is 10 meters long, 7 meters wide, and 5 meters high. t

Lerok [7]

First, let's find the volume of the two boxes.

V = lwhV=lwhV, equals, l, w, h

V=10\times7\times5V=10×7×5V, equals, 10, times, 7, times, 5

V= \blue{350} \text{ cubic meters}V=350 cubic metersV, equals, start color blue, 350, end color blue, space, c, u, b, i, c, space, m, e, t, e, r, s

V = lwhV=lwhV, equals, l, w, h

V=4\times10\times8V=4×10×8V, equals, 4, times, 10, times, 8

V= \pink{320} \text{ cubic meters}V=320 cubic metersV, equals, start color pink, 320, end color pink, space, c, u, b, i, c, space, m, e, t, e, r, s

Hint #22 / 3

Since my porcupine can play in both boxes, we need to add the volumes of the two boxes.

\blue{350}+\pink{320}=\green{670}350+320=670start color blue, 350, end color blue, plus, start color pink, 320, end color pink, equals, start color green, 670, end color green

Hint #33 / 3

My porcupine has \green{670}670start color green, 670, end color green cubic meters of space to play in his fort.

670 is your answer i hoped this help please rate me thanks :)

What is true of the coefficient of variation?

DedPeter [7]

Answer:

A. The coefficient of variation is best used when comparing two data sets that use the same units of measure.

Step-by-step explanation:

The coefficient of variation (CV), is simply the standard deviation (itself a measure of variance or variation) relative to the mean of a distribution.

The coefficient of variation expresses a random variable’s variability in percentage terms. Therefore it is possible, through the coefficient of variation, to compare the variability of data across different samples, especially if the random variables are recorded in different units of measurement (such as cm, kg and minutes).

A coefficient of variation is always interpreted as a percentage. Mathematical representation is:

$Coefficient\ of\ variation\ = \frac{Standard\ deviation}{Mean}\ \%$

The coefficient of variation is best used when comparing two data sets that use the same units of measure.

Hence, the option (A) is the correct option.

How do you do coordinates?

suter [353]

Answer:

Start at (0, 0), or the origin. Just go to (0, 0), which is the intersection of the x and y axes, right in the center of the coordinate plane. 2. Move over x units to the right or left. Let's say you're working with the set of coordinates (5, -4). Your x coordinate is 5.
