Answer:

Proved!

Step-by-step explanation:

For two functions f(x) and g(x) to be inverses of each other then;

f(g(x)) = x and g(f(x)) = x condition must be satisfied.

<u>Checking: A. f(x) = 7x³ + 10 and g(x) = ∛</u>\frac{x - 10}{7}<u />

<u />

So f(g(x)) = 7(\sqrt[3]{(x- 10)/7})³ + 10

We get; 7(\frac{x - 10}{7}) + 10 = x - 10 + 10 = x (*<em>This is correct!)</em>

<em />

So g(f(x)) = \sqrt[3]{((7x^3 + 10) - 10)/7}

Ten cancels out and we are left with;

\sqrt[3]{7x^3/7} = \sqrt[3]{x^3} = x (* <em>This is also correct!)</em>

1. m∠QPR =<br><br> 2. m∠QTP =<br><br> 3. RP =<br> Show all the work
alex41 [277]

Answer:

1. 30°

2.90°

3. 12 units

Step-by-step explanation:

I can't believe there's nothing confirming that this is a parallelogram/a rhombus?! Assuming is awful, and I wish you could say you can't know for sure lol but for the sake of this answer, let's just call it a rhombus. (There was probably some context elsewhere that you didn't put over here, hopefully.)

1.

The reason I say this is: in a rhombus, the diagonals bisect the angles. This means that the diagonals split the angles they meet into two equal parts. That way, it would make sense. m∠QPR=m∠SPR=30°.

2.

If it is a rhombus, the diagonals are perpendicular to each other, so m∠QTP should be 90°.

3.

Diagnonals in a rhombus (and in any parallelogram) bisect each other, so PT=TR=6, and RP=PT+TR=12 units.

Sorry if this is all dreadfully wrong, and I hope I helped you!
