The values of p and q in the function f(x) = 2x³ + 17x² - 3px - 5q is p = 8, q = 27

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

x - 3 (i.e. x = 3) and x + 9 (i.e. x = -9) are factors of f(x) = 2x³ + 17x² - 3px - 5q

Hence:

f(3) = 0

2(3)³ + 17(3)² - 3p(3) - 5q = 0  (1)

Also:

2(-9)³ + 17(-9)² - 3p(-9) - 5q = 0  (2)

Hence, p = 8, q = 27

The values of p and q in the function f(x) = 2x³ + 17x² - 3px - 5q is p = 8, q = 27

If f(7) = 22, then f^-1(22) = [?]​

The required value of the given inverse function f⁻¹(22) will be 7.

<h3>What is an inverse function?</h3>

The inverse function is defined as a function obtained by reversing the given function.

Given that f(7) = 22

To determine the value of the given inverse function f⁻¹(22)

An inverse function's main objective is to show the value that occurs in a specific function value. Which means :

If we have f(x) and f⁻¹(x), then

if f(a) = b then f⁻¹(b) = a

As per the given question, we have

⇒ f(7) = 22 then f⁻¹(22) = 7

Therefore, the required value of the given inverse function f⁻¹(22) will be 7.

PLZ HELP AND EXPLAIN THIS PLZ
AURORKA [14]

Answer:

A. <u>4</u> trucks will make $80 because 4 × 20 = 80, so they need to wash <u>38</u> cars to make the other $380 because 38 × 10 = 380.

($80 + $380 = $460)

B. <u>15</u> trucks will make $300 because

15 × 20 = 300, so they need to wash <u>16</u> cars to make the other $160 because 16 × 10 = 160. ($300 + $160 = $460)

C. <u>21</u> trucks will make $420 because

21 × 20 = 420, so they need to wash <u>4</u> cars to make the other $40 because 4 × 10 = 40.

($420 + $40 = $460)

D. <u>27</u> trucks will make $540, so they won't have to wash any cars because they would have already exceeded their goal of $460.

Not sure what to do for letter E. Sorry. I hope the rest makes sense though :)

Can someone plz help me. There is an equation and the cost too.
bonufazy [111]

Answer:

C = 40p

Cost for 15 people: 600 dollars

Step-by-step explanation:

The amusement park charges $40 per person.

That can be represented as 40 × <em>P</em> or 40<em>P</em>.

<em>C</em> is equal to the cost of admission for <em>P</em> people.

So, <em>C</em> = 40<em>P</em>

<em />

<em>C </em>= 40<em>P</em>

<em>C</em> = 40(15)

<em>C</em> = 600

The cost of admission for 15 people is 600 dollars.

Hope that helps.
