Answer:

see explanation

Step-by-step explanation:

If f(x) and $f^{-1}$ are inverse functions, then

f( $f^{-1}$ )(x) = x

Thus substitute x = $f^{-1}$ (x) into f(x)

f( $\frac{x+6}{5}$ )

= 5 ( $\frac{x+6}{5}$ ) - 6

= x + 6 - 6

= x

Thus f(x) and $f^{-1}$ (x) are inverse functions

5,25,125 find 10th term

anastassius [24]

Answer:

9765625

Step-by-step explanation:

There is a common ratio between consecutive terms , that is

r = 25 ÷ 5 = 125 ÷ 25 = 5

This indicates the sequence is geometric with n th term

$a_{n}$ = a₁ $r^{n-1}$

where a₁ is the first term and r the common ratio

Here a₁ = 5 and r = 5 , then

a₁₀ = 5 × $5^{9}$ = 5 × 1953125 = 9765625

A 20-gallon container is filled halfway with a mixture that is $90\%$ vinegar and $10\%$ water. How many gallons of water must b

Yuki888 [10]

Answer:

5 gallons of water must be added.

10 gallons to start with

adding 'x' gallons of water final volume = 10 + x

.9 (10) = amount of vinegar

.1(10) = amount of water

amount of vinegar before and after water addition is constant

.9(10) = .6(10+x)

9 = 6 + .6x

3 = .6x

x = 5 gallons of water to be added
