First, subtract 20 from 108 to get 88. Then divide the 88 by 4 and get 22. We then know that the height of a kiwi is 22 inches (Don't forget your units of inches), hope this helped.

A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the
defon

Answer:

Price of widget to break even= $37.9

Step-by-step explanation:

We are told that the equation representing the amount of profit, y, made by the company, in relation to the selling price of each widget, x is;

y = -8x² + 348x - 1705

Now, the company will break even when it has made no profit. That is when, y = 0

Thus;

0 = -8x² + 348x - 1705

Rearranging,

8x² - 348x + 1705 = 0

Using quadratic formula ;

x = [-b ± √(b² - 4ac)]/2a

x = [-8 ± √(-348² - 4•1•1705)]/(2 x 8)

x = $5.63 or $37.87

We'll use $37.87 because it is the highest price for which no profit is made, and higher price means that we could sell least number of products to earn a certain amount of money.

We are told to approximate to nearest cent. Thus,

Price of widget = $37.87 ≈ $37.9

Use the information to answer the following question.
trasher [3.6K]

Answer:

D is the answer

Step-by-step explanation:

For a: g(x) = 1 when x = 1, for f(x) 1^2 - 2(1) + 2 = 1, a is true.

For b: Both functions do have all real numbers for their domain, b is true

For c: the y-intercept of g(x) is x = 0, for f(x), it is 0^2 - 2(0) + 2 = 2, c is true

For d: g(3) = 7, f(3) = 3^2 - 2(3) + 2  = 5, d is false.

Who knows how you do you this??
Monica [59]
Hi!
Okay, so this actually isn't too bad! (For number 5) Just add the negative x over to get 2x. Then subtract 2 over to get -10. Then divide by 2 (-5) and you're done! For the rest, do the same thing. Get the x's on one side, get the regular numbers on the other, and divide! Hope that helped!
