Answer:
40 ft
Step-by-step explanation:
The maximum height of the ball is the y- coordinate of the vertex
Given a parabola in standard form then the x- coordinate of the vertex is
= - ![\frac{b}{2a}](https://tex.z-dn.net/?f=%5Cfrac%7Bb%7D%7B2a%7D)
h(t) = - 16t² + 48t + 4 ← is in standard form
with a = - 16, b = 48 , thus
= -
= 1.5
Substitute t = 1.5 into h(t) for max. height
h(1.5) = - 16(1.5)² + 48(1.5) + 4
= - 36 + 72 + 4
= 40
All that you need to do here is to multiply 5.5 by 11.5 which equates to...
=5.5x11.5
=63.25
because the second decimal is five you have to round up so that means that the answer is 63.3km
The area of the bare spot the gardener needs to replant is 201 square feet
Step-by-step explanation:
We have to find the area of the circular bare spot
Given
Radius of bare spot = r = 8 inches
The formula for area of a circle is given by:
![Area=A = \pi r^2](https://tex.z-dn.net/?f=Area%3DA%20%3D%20%5Cpi%20r%5E2)
putting the value
![A = 3.14 * (8)^2\\= 3.14 * 64\\=200.96](https://tex.z-dn.net/?f=A%20%3D%203.14%20%2A%20%288%29%5E2%5C%5C%3D%203.14%20%2A%2064%5C%5C%3D200.96)
Rounding off to nearest foot
201 ft^2
Hence,
The area of the bare spot the gardener needs to replant is 201 square feet
