The graph of the function C(x) = −0.34x2 + 12x + 62 is shown. The function models the production cost, C, in thousands of dollar

Virty [35]

Answer:

0 ≤ x < 1.12 and 34.18 < x ≤ 39.87

Step-by-step explanation:

Let

x ----> is the number of tires produced, in thousands

C(x) ---> the production cost, in thousands of dollars

we have

$C(x)=-0.34x^{2} +12x+62$

This is a vertical parabola open downward (the leading coefficient is negative)

The vertex represent a maximum

The graph in the attached figure

we know that

Looking at the graph

For the interval [0,1.12) -----> $0\leq x$

The value of C(x) ----> $C(x) < 75$

That means ----> The production cost is under $75,000

For the interval (34.18,39.87] -----> $34.18 < x\leq 39.87$

The value of C(x) ----> $C(x) < 75$

That means ----> The production cost is under $75,000

Remember that the variable x (number of tires) cannot be a negative number

therefore

If the company wants to keep its production costs under $75,000 a reasonable domain for the constraint x is

0 ≤ x < 1.12 and 34.18 < x ≤ 39.87

- 81 %

Step-by-step explanation:

To find the percentage change;

([Current – Initial] / Initial) * 100

([14 - 75] / 75) * 100

(-61 / 75) * 100

(-0.81333) * 100

= - 81.3333 %

To the nearest percentage;

Footlocker in the mall is having a 25% off sale on all tennis shoes. Joe paid $67.50 for his

marta [7]

Answer:

The original price of the shoes was $90.

Step-by-step explanation:

25% off means the price Joe paid for it is 75% of the original price.

Set up an equation:

75/100 = 67.50/x

Cross multiply

75 × x = 100 × 67.50

75x = 6750

x = 90

Check our work:

First solve for 25% off of 90 (our answer).

25% = 0.25

90 × 0.25 = 22.50

Next, subtract the discount from 90.

90 - 22.50 = 67.50

67.50 was what Joe paid so this is correct.

Kruka [31]

The correct unscrambling of whyrot is worthy.

<h3>What is unscrambling?</h3>

A word unscrambler is essentially a gadget that you feed all the letters into and it rearranges them to reveal all potential word combinations.
Some might be concerned that this is a cheating method. However, if everyone playing the game has the option of using a word unscrambler, then the playing field is unquestionably even.
A player may opt not to use the word generator and instead come up with their own list of terms. Having said that, they might want to utilize it afterward to assess their performance and review the entire list of terms they could have used.
