Answer do 4 *11
Step-by-step explanation:
The incenter of a triangle is equidistant from all sides of the triangle
The incenter is the center of the biggest circle that can be drawn in the triangle, and is called incircle
The incircle will be tangent to all sides of the triangle.
Observation:
In an equilateral triangle the incenter, circumcenter, and centroid are all the same
The maximum height of an object is the greatest height the object can reach. The maximum height the rocket reaches is 40.2 feet
<h3>Vertex form of an equation</h3>
The maximum height of an object is the greatest height the object can reach. Given the equation that represent the height of the rocket.
f(t) = -15t² + 48t
The maximum height of the rocket occur at the point where:
t = -b/2a
t = -48/2(-15)
t =48/30
t = 1.6secs
Substitute t = 1.6 into the function as shown:
f(1.6) = -15(1.6)² + 48(1.6)
f(1.6) = -38.4 + 76.8
f(1.6) = 40.2
Hence the maximum height the rocket reaches is 40.2 feet

All we need to do is substitute and solve:
f(-5) = 5(-5) + 40
f(-5) = -25 + 40
f(-5) = 15
Best of Luck!
