The output value of f(3) in the given function f(x) = 2x² + 5√(x-2) is 23.

<h3>What is the output value of f(3) in the given function?</h3>

Given the data in the question;

Function: f(x)= 2x²+5√(x-2)
f(3) = ?

To determine the output value, we replace the variable x with 3 in the given function.

f(x) = 2x² + 5√(x-2)

f(3) = 2(3)² + 5√(3-2)

We simplify

f(3) = 2(9) + 5√(1)

f(3) = 18 + 5√(1)

f(3) = 18 + 5(1)

f(3) = 18 + 5

f(3) = 23

Therefore, the output value of f(3) in the given function f(x) = 2x² + 5√(x-2) is 23.

ace bike rentals rents bikes for $28 per day. Renters can keep the bike for 8 hours. Bart's bikes rents bikes for $30 per day. R

lyudmila [28]

Bart company charges a lower rate. It is lower by rate $ 0.5 per hour

<h3><u>Solution:</u></h3>

Given that Ace bike rentals rents bikes for $28 per day. Renters can keep the bike for 8 hours

Also given that Bart's bikes rents bikes for $30 per day. Renters can keep the bike for 10 hours

To find: company that charges lower rate

Let us find the hourly rate of Ace and Bart

$\text {hourly rate }=\frac{\text { Rental price }}{\text { total time in a day }}$

<em><u>Hourly rate of Ace company:</u></em>

Rental price = $28

total time in a day 8 hours

$\text {hourly rate }=\frac{28}{8}=3.5$

So the hourly rate of Ace company is $ 3.5 per hour

<em><u>Hourly rate of Bart company:</u></em>

Rental price = $ 30

total time in a day 10 hours

$\text {hourly rate }=\frac{30}{10}=3$

So the hourly rate of Bart company is $ 3 per hour

<em><u>Comparing hourly rate of both companies</u></em>

Ace company is $ 3.5 per hour

Bart company is $ 3 per hour

Bart company < Ace company

3 < 3.5

Thus bart company charges a lower rate

<h3><em><u>How much lower?</u></em></h3>

hourly rate of Ace company - hourly rate of Bart company = 3.5 - 3 = 0.5

So, it is lower by rate $0.5 per hour
