96-49=47 feet

if the diver swam 96 feet deep...then goes up 49 feet....that means his distance below the lake reduced hence you subtract

Diving beneath would be a negative number so:
-96 + 49 = - 47 ft below the surface of the water

You paid $28.80 for a shirt that was on sale for 20% off of the original price. What was the original price?

The answer is 36.

Because 20% of 36 is equal to 7.2

And 36 - 7.2 = 28.80

<span>1. Measure the distance the solvent front traveled from the baseline (m1). 2. Measure the distance the reactant b spot traveled (the center of the spot) (m2). 3. To determine the rf, divide (m2/m1). 4. Significant figures- use 2 so the answer should be written to the hundredths place as the spot will not travel farther than the solvent front.</span>

Identify the inverse of the following.

posledela

Answer:

$f^{-1}(x)=\sqrt{\frac{1}{8}(-x+4)}$

Step-by-step explanation:

Given function is,

f(x) = -8x² + 4

Step to find the inverse of the function,

Step 1

Write the function in the form of an equation,

y = -8x² + 4

Step 2

Interchange the variables 'x' and 'y',

x = -8y² + 4

Step 3

Solve the equation for y,

x = -8y² + 4

x - 4 = -8y²

-x + 4 = 8y²

y² = $\frac{1}{8}(-x+4)$

$y=\sqrt{\frac{1}{8}(-x+4)}$

Therefore, inverse of the function f(x) will be,

$f^{-1}(x)=\sqrt{\frac{1}{8}(-x+4)}$
