Answer:
4. dy/dx = -2
8. dy/dx = 1/2 x^(-3/2)
10/ dy/dr = 4 pi r^2
Step-by-step explanation:
4. y = -2x+7
dy/dx = -2(1)
dy/dx = -2
8. y = 4 - x^-1/2
dy/dx = - (-1/2x^ (-1/2-1)
dy/dx = 1/2 x^(-3/2)
10. y = 4/3 pi r^3
dy/dr = 4/3 pi (3r^2)
dy/dr = 4 pi r^2
Probability that he makes a goal =2/5
probability that he kicks 3 in 3 = (2/5)*(2/5)*(2/5)
= 8/125.
Answer:
(2,-9)
Step-by-step explanation:
Set the quadratic equal to zero.
Factor
Set each of these factors to zero
and
and
Plot the midpoint of the two values.
So the middle term is 2 and the other terms are 5 and -1.
Now the vertex is
So the vertex is
(2,-9)
