The main idea is the square root of the hypotenuse is equal to each other side squared and then added together.

A squared + B squared= C squared. The idea is used to find the side of the hypotenuse when sides A and B are given but C is not

If g(x)=4x-6 then g^-1(x)=? (1) -4x+6 (2)-1/4x+1/6 (3)1/4x+3/2 (4)1/4x+6

kati45 [8]

Given:

$g(x)=4x-6$

To find:

The function $g^{-1}(x)$ .

Solution:

we have,

$g(x)=4x-6$

Put g(x)=y.

$y=4x-6$

Interchange x and y.

$x=4y-6$

Isolate y.

$x+6=4y$

$\dfrac{x+6}{4}=y$

$y=\dfrac{x+6}{4}$

Substitute $y=g^{-1}(x)$ .

$g^{-1}(x)=\dfrac{x+6}{4}$

$g^{-1}(x)=\dfrac{x}{4}+\dfrac{6}{4}$

$g^{-1}(x)=\dfrac{x}{4}+\dfrac{3}{2}$

Therefore, the correct option is (3).

Solve (3^p times 81 = 9) for p

kherson [118]

Answer:

p = -2

Step-by-step explanation:

Start by dividing both sides by 81 to get the power by itself.

$3^p \cdot 81 = 9\\\\3^p=\frac{9}{81}=\frac{1}{9}$

Write the fraction using a power of 3.

$3^p=\frac{1}{3^2}\\\\3^p=3^{-2}\\\\p=-2$

This assumes you know about negative exponents: $a^{-n}=\frac{1}{a^n}$
