<span>a) wouldn't you just divide it by 4?
b)52/3=17 1/3
17 1/3*10.99= 190.493333333...(you get the point)</span>
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!
We know that
[perimeter of rectangle]=2*[length+width]
length=(2x-7)
width=(x²-5)
[perimeter of rectangle]=2*[(2x-7)+(x²-5)]----> 2*[x²+2x-12]---> 2x²+4x-24 in
the answer is
(2x²+4x-24) in
The area of a triangle is found using the formula Area = 1/2 x base x height.
Base = 8
Height = 18.
The area of 1 triangle = 1/2 x 8 x 18 = 72 square units.
There are a total of 4 sides, so total area = 72 x 4 = 288 units ^2
