Answer:

f(3) = (-∛150)/10

Step-by-step explanation:

Put 3 where x is and evaluate. If you don't want the decimal, you can rationalize the denominator to get an exact form.

f(3) = ∛(3/(-7·3+1)) = ∛(-3/20)

= -∛(3·50/(20·50)) = (-∛150)/10 ≈ -0.5313292845913...

_____

Multiplying numerator and denominator by 50 makes the denominator 1000, a perfect cube.

A customer bought a car and paid $1,080 in sales tax.The rate is 6%?

Ghella [55]

The price of car is $18000

Step-by-step explanation:

Given

Sales tax on car = $1080

Rate = 6%

Let x be the price of the car

We know that as the rate of sale tax is 6%, 6% of x is 1080

Using mathematical notation

0.06x = 1080

Dividing both sides by 0.06

$\frac{0.06x}{0.06} = \frac{1080}{0.06}\\\\x = 18000$

Hence,

The price of car is $18000

Write an explicit rule for the nth term of the sequence 64,48,36,27

melisa1 [442]

Answer:

aₙ = 64(3/4)ⁿ⁻¹

Step-by-step explanation:

Given sequence:

64, 48, 36, 27

We can observe that:

27/36 = 3/4
36/48 = 3/4
48/64 = 3/4

This is a GP with the first term of 64 and common ratio of 3/4.

The equation for the nth term is:

aₙ = 64(3/4)ⁿ⁻¹
