Answer:

the square root of 3200

Step-by-step explanation:

I'm not sure if this is right, because the format of the question wasn't clear, but it sounded like we have to find the diagonal distance of the room from one corner to the opposite. If the sides are 40ft long on both sides, we can use the Pythagorean Theorem to solve this:

40^2+40^2=c^2

1600+1600=c^2

3200=c^2

c=sqrt(3200)

or about 56.5

There is 3600 seconds per hour.
 Multiply the speed per second by 3600 to get the speed in miles per hour then convert to kilometer/hour.

4.9 * 3600 = 17,640 miles per hour

17,640 x 1.6 = 28,224 kilometers per hour

Which are characteristics of the graph of the function f(x) = (x + 1)2 + 22 Check all that apply.
Sunny_sXe [5.5K]

Answer: The domain is all real numbers

I can't say that the y intercept is 3 because when you distribute,

f(x) = (x + 1)2 + 22 \\ f(x) = 2x + 2 + 22 \\ f(x) = 2x + 24

It seems like the y intercept is 24.

I don't know how to answer this question.
laiz [17]

Answer:

- 39/8y

Step-by-step explanation:

First you need to find a common denominator:

There is already a y in both denominators, so you don't have to worry about that. Since only one denominator has an 8, the other needs to have an 8, so you need to multiply the first fraction by 8 → - 4/y * 8 = - 32/8y

From here you can subtract the numerators:

- 32/8y +(- 7/8y) = - 39/8y

Because you are adding a negative to a negative, it makes the number mroe negative


I hope this helps!
