Grade 10 math help please. Please show work

Answer:

43.94?

Step-by-step explanation:

I think if you use inverse cos you should get the correct number. So, to find cos, you need to know the adjacent side and the hypotenuse. Here, the reference angle would be the person holding the kite. The distance from the person to the barn is the adjacent side, which is 18. The string of the kite, I assume, would be 25.

cos(∅) = $\frac{18}{25}$

cos(∅) = 0.72

cos⁻¹(0.72) = 43.94

I don't know if that's what you're looking for, but... If it's not correct, lmk so I can rewrite it. :)

For questions 7 – 8, use the following functions: f(x) = 4x + 3x g(x) = 2x – 5 7. Find (f + g)(x). 8. Find (f – g)(x).

densk [106]

Answer:

7) (f+g) (x) = 4^x + 5x -5

8) (f-g) (x) = 4^x + x - 5

Step-by-step explanation:

7) Find (f +g)(x)

(4^x + 3x + 2x - 5)

(4^x + 5x -5)

(f+g) (x) = 4^x + 5x -5

8) Find (f-g)(x)

(4^x + 3x - 2x - 5)

(4^x + x - 5)

(f-g) (x) = 4^x + x - 5

A shoe store sells about 200 pairs of a new basketball shoe each month when it charges $60 per pair. For each $1 increase in pri

Verizon [17]

Answer:x = the number of $1 increases in price

Price = ($60 + $1x) = (60+x)

Pairs of shoes (200 - 2x)

You have a quadratic Revenue = (60+x)(200-2x)

The quad max is when x = 20

Therefore they should charge 60+ 20 = $80
