Answer:
131.95yd squared
Step-by-step explanation:
A=2πrh+ 2 r(2)=2*π*3*4+2*π*3(2)~131.94689yd(2)
Answer:
The first one. Y^2 + Z^2 = X^2
Step-by-step explanation:
Using the Pythagorean theorem you would do a^2 + b^2= c^2 where a=y b=z and c=x.
Answer:
y + 9 = 1/5(x + 8)
Step-by-step explanation:
Point-slope form: y - y₁ = m(x - x₁)
Substitute the values into the equation.
y - (-9) = 1/5(x - (-8)
y + 9 = 1/5(x + 8)
<span>a)
Acceleration of stone = 10
Integrate:
So velocity = 10t
Integrate again:
So distance from starting point = 5t^2
Distance from ground = 450-5t^2
b)
450 - 5t^2 = 0
9.48 seconds
c) velocity = 10t
Put the time into this to give:
94.8 m/s
d.
Velocity = 10t + 5
Integrate again:
5t^2 + 5t
Solve
5t^2 + 5t = 450
Gives 9 seconds</span>
