NO JOKE 70 POINTS!!!!!!!! I WILL GIVE BRANLIEST AND RATE!!!! MATH EXPERTS COME HELP!!! AT LEAST TAKE A LOOK!!! LIKE WHERE ARE TH

E GENIUSES!!EASY I AM JUST DUMBREAD THIS AND THEN ANSWER THE QUESTION
READ THIS THEN ANSWER THE QUESTION:
There are so many items for sale in our world! Some of the items you can buy will appreciate in value. This means that as time passes, the value of the item increases. If you decide to sell the item at a later time, you should be able to sell it for more than you paid. Some common examples of items that appreciate in value include houses, stocks, and some types of art.
Other items you can buy will depreciate in value. This means that as time passes, the value of the item decreases. If you decide to sell the item at a later time, you will likely have to sell it for less than you paid for it. Cars, game systems, and jewelry are examples of items that usually depreciate as time passes. The majority of items that depreciate never reach a value of $0. Their worth attains some minimum, positive value that is greater than $0 and then their price stabilizes.
In 1981, IBM manufactured and sold one of the first personal computers. The machine was called the IBM Personal Computer (PC) 5150 and the full model retailed for $3,000. Similar to modern technology, the value of this item depreciated over time. The function that models how the PC 5150 depreciated as time passed is , where x is the number of years after 1981 and f(x) is the value of the PC 5150.


1. Evaluate the depreciation function at f(0). Show your work and use function notation as needed. What does this number represent?

2. Find the vertex of the depreciation function. What does this point represent in context of this problem? Show your work and explain your process.

marissa [1.9K]

Answer:

<h2>You will ride for 4 hrs 8min</h2>

Step-by-step explanation:

What we are expected to solve for that the problem did not expressly state is most likely the number of hours that you could ride for an amount of $65.

firstly we need to model the inequality (equation) for this scenario.

the constant fee= $3 additional fee for helmet

3+15n\leq 65\\\\

We can now solve for n since the above inequality satisfies the condition presented in the problem statement.

 3+15n\leq 65\\\\15n\leq65-3\\\\ 15n\leq 62

Divide both sides by 15 to find n

n\leq 62/15\\\\n\leq 4hrs -8min

Which table represents a direct variation function?
sineoko [7]

Answer:

Option C is correct.

Step-by-step explanation:

A direct variation function is

y/x = k

i.e. we can say that the ratio of y and x is equal to a constant value k.

We will check for each Option given.

Option A

7/2 = 7/2

8/3 = 8/3

9/4 = 9/4

10/5 = 2

11/6 = 11/6

Option D is incorrect as y/x ≠ k as ratio of y/x for each value of table doesn't equal to constant

Option B

-3/2 = -3/2

-5/4 = -5/4

-6/6 = -1

-7/8 = -7/8

-8/10 = -4/5

Option B is incorrect as y/x ≠ k as ratio of y/x for each value of table doesn't equal to constant

Option C

10/-5 = -2

8/-4 = -2

6/-3 = -2

4/-2 = -2

2/-1 = -2

Option C is correct as y/x = k as ratio of y/x for each value in table c is equal to constant value -2

Option D

-3/-2 = 3/2

-3/1 = -3

-3/0 = 0

-3/1 = -3

-3/2 = -3/2

Option D is incorrect as y/x ≠ k as ratio of y/x for each value of table doesn't equal to constant .

SO, Option C is correct.
