Given the the table of values below which of the following ordered pairs are found on the graph of the inverse function?

Alja [10]

Answer:

Step-by-step explanation:

From the table we see that

$f(-2)=12\\ \\f(-1)=10\\ \\f(0)=8\\ \\f(1)=6\\ \\f(2)=4$

Thus, the inverse function has the rule

$f^{-1}(12)=-2\\ \\f^{-1}(10)=-1\\ \\f^{-1}(8)=0\\ \\f^{-1}(6)=1\\ \\f^{-1}(4)=2$

This gives us that ordered pairs

$(12,-2),\ (10,-1),\ (8,0),\ (6,1),\ (4,2)$

are on the graph of the inverse function

Keisha swims 18 ft from one side of her circular pool to the other, swimming straight through the center. She then swims one tim

elena-s [515]

Answer:

Swimming one time around the pool is 56.5 ft

Step-by-step explanation:

Swimming 18 ft from one side of her circular pool to the other, swimming straight through the center means the circular swimming pool has a diameter of d=18 ft.

The circumference of the circle is calculated using:

$c = \pi \: d$

where d=18 is the diameter and π=3.14 as given.

We substitute the values to get:

$c = 3.14 \times 18$

$c = 56.52$

We approximate to the nearest tenth to get:

$c = 56.5ft$

Jen says that the solutions of the inequality -2(3 – x) > 2x – 6 are all real numbers. Do you agree with your friend? Explain

Maslowich

Answer:

I disagree

'No it won;t

Step-by-step explanation:

Given the inequality functions;

-2(3 – x) > 2x – 6

Open the parenthesis

-2(3) -2(-x) > 2x - 6

-6 + 2x > 2x - 6

Collect like terms

2x-2x > -6 + 6

0x > 0

x > 0/0

<em>The value of x does not exist on any real number. I disagree with my friend since the value of x is an indeterminate function. If the inequality were ≥, it won't change anything as the value of x won't still exist on any real number </em>
