Answer:
The answer for y is -300.
Step-by-step explanation:
It's -300 because when you divide 125 by -25 you get -5 for the first y and x. So for the next one you just get 12 times -25 to get -300 and that's how you get your y.
Answer:
30x^5 + 15x^4 + 105x^3
Step-by-step explanation:
V = l*w*h
l = 3x
w = 5x^2
h = 2x^2 + x + 7
l*w = 3x * 5x^2 = 15x^3 (add exponents when multiplying variables)
l*w = 15x^3
V = l*w*h = 15x^3(2x^2 + x + 7) = 30x^5 + 15x^4 + 105x^3
Answer:61.8°
Step-by-step explanation:
Length of arc=(theta)/360 x 2 x π x radius
9.7=(theta)/360 x 2 x 3.14 x 9
9.7=56.52(theta)/360
cross multiply
9.7 x 360=56.52(theta)
3492=56.52(theta)
Divide both sides by 56.52
3492/56.52=56.52(theta)/56.52
61.8=theta
theta=61.8°
