The relation is the set of ordered pairs of point drawn in the graph

The points are:

(-2, 3), (0, 1), (2, -1), (3, -2)

So the relation is:

R = {(-2, 3), (0, 1), (2, -1), (3, -2)}

The domain is the values of x in the ordered pairs

x = -2, 0, 2, 3

The domain = {-2, 0, 2, 3}

The range is the values of y in the ordered pairs

y = 3, 1, -1, -2

Arrange them in the set

The range = {-2, -1, 1, 3}

A company rents water tanks shaped like a cylinders. Each tank has a diameter of 12 feet and a height of 3 feet. The cost is $2

12345 [234]

Answer:

$\$678.58$

Step-by-step explanation:

step 1

Find the volume of the tank

we know that

The volume of a cylinder (water tank) is equal to

$V=\pi r^{2}h$

in this problem we have

$r=12/2=6\ ft$ -----> the radius is half the diameter

$h=3\ ft$

substitute

$V=\pi (6^{2})(3)=339.29\ ft^{3}$

step 2

Find the cost

$339.29\ ft^{3}*2\frac{\$}{ft^{3}}=\$678.58$

Find the slope and y-intercept value in 7x– 2y = -16.

Margaret [11]

Answer:7/2

(0,8)

Step-by-step explanation:

Subtract 7x from both sides

-2y=-7x-16

Divide both sides by -2

y=7/2x+8

Slope 7/2

PLZ EXPLAIN AND I'LL GIVE BRAINLY!!!!

Hello there!

Given the sequence:

$\displaystyle \large{ 1, - 3,9, - 27,...}$

The question reveals it to be geometric sequence since it has common ratio.

Geometric Sequence / Ratio Formula

$\displaystyle \large{r = \frac{a_{n + 1}}{a_n} }$

Define 'r' as common ratio.

First, let's check the common ratio by using the formula above.

Ratio Check

$\displaystyle \large{r = \frac{ - 3}{1} \longrightarrow - 3 } \\ \displaystyle \large{r = \frac{ 9}{ - 3} \longrightarrow - 3 } \\ \displaystyle \large{r = \frac{ - 27}{9} \longrightarrow - 3 }$

Therefore, the common ratio or r-value is -3.

To find the 7th term of sequence, you can by using the General Geometric Terms.

General Term of Geometric

$\displaystyle \large{a_n = a_1 {r}^{n - 1} }$

a1 is defined as the first term of sequence.

r is common ratio.

n is the term.

Since we want to find 7th term:

a1 = 1
r = -3
n = 7

$\displaystyle \large{a_7 =1{( - 3)}^{7 - 1} } \\ \displaystyle \large{a_7 =1{( - 3)}^{6} } \\ \displaystyle \large{a_7 =729 }$

Therefore, the 7th term of this sequence is 729.

Let me know if you have any questions!
