KE=1/2mv^2
50000=(0.5)(1000)v^2
v^2=50000/500
v^2=100
v=10 ms^-1
Answer:
We have, y=f(x)
From graph, when x = 2, y =f(x)=-5. So, functional value at x=2, f(2) = -5
Pass your phone number u fine I’m joking unless
This seems like a right triangle problem.
So assuming 14 feet is the hypotenuse and 4 feet is a leg of the right triangle, we can use the pythagorean theorem (
) to solve for the height of the house, in which we shall name it x.
So, the equation is
.
Solve for x:
16+x^{2}= 196
x^{2}= 196-16
x^{2}= 180
x = 6√5 feet
Hope this helps!
Answer:
2
Step-by-step explanation:
because when x, the input, is -3, the y, the output, is 3
