Use the law of cosines:
c² = 8² + 11² - 2•8•11 cos(37°)
c² ≈ 44.4402
c ≈ 6.66634
Slope undefined
no y-intercept
unless you mean <span>y=2x+7
then slope 2
y-intercept 7

Answer:
sqrt(2h/g) = t
Step-by-step explanation:
h=1/2gt^2
We want to get t alone
First multiply by 2 to get rid of the fractions
2*h=2*1/2gt^2
2h = g t^2
Then divide by g on each side
2h/g = g t^2/g
2h/g = t^2
Then we need to take the square root of each side
sqrt(2h/g) = sqrt(t^2)
Normally we take the ± sqrt, but since time must be positive ( cannot have negative time)
sqrt(2h/g) = t
Answer:
150 m^2 is the surface area
125 m^3 is is the volume
Step-by-step explanation:
Surface area: 6 * 5^2 = 6 * 25 = 150
Volume: 5^3 = 125
