we are given
where
d is the horizontal distance the ball traveled in yards
f(d) is the height, in yards of the ball at d horizontal yards
Initial height:
For finding initial height , we can plug d=0
So, initial height is 0.8 yard
Initial Velocity:
We can find derivative
now, we can plug d=0
so, initial velocity is 5.4 yard vertically / yard horizontally
Hence , option-B.......Answer
6/4 =rise/run
3/2 if it was simplified
Answer:
f^-1(x)=³√[(x+7)÷4]
Step-by-step explanation:
f(x)=4x^3-7
y=4x^3-7
interchange 'y' with 'x'
x=4y^3-7
make y the subject
4y^3=x+7
divide by 4 both sides
y^3=(x+7)÷4
multiply by the cube root both sides
³√(y^3)=³√[(x+7)÷4]
y=³√[(x+7)÷4]
f^-1(x)=³√[(x+7)÷4]
