The question is asking you to find the axis of symmetry, which is the x-value of the vertex. In order to do that you need to factor the function to find the zeros and add the zeros together and divide by two to find the axis of symmetry.
y=-16x^2+608x
y=-16x(x-38)
Zeros: x=0 and x=38
38/2=19
Therefore it takes 19 seconds for the projectile to reach its maximum height.
Hope this helps!
Answer:
16
Step-by-step explanation:
Subtract DE from CE and you will get the value of CD
27 - 11 = 16
Step-by-step explanation:
mass of the object=m=4 kg
the net force exerted on it=F=24N=kgm/s²
the acceleration of the object=a=?
formula for calculating the acceleration=
F=ma
plug in the values
24kgm/s²=4kga
divide each side by 4
24kgm/s²/4 kg=4kga/4kg
a=6m/s²
He would have to sale $500,000
9% of $500,000 is $45,000
So $30,000 plus $45,000 is $75,000
