Answer: In-center of the triangle is point N.
Step-by-step explanation:
We are given a triangle △JKL.
In triangle △JKL, they drew perpendicular bisectors of each side of the triangle.
Also we are given angle bisectors of the each of angles in given triangle.
Note: Perpendicular bisector is a line that intersect a segment into two equal parts and also perpendicular to it.
<em>Also note that the in-center is the point forming the origin of a circle inscribed inside the triangle. It is constructed by taking the intersection of the angle bisectors of the three vertices of the triangle.</em>
<h3>We can see that angle bisectors are intersecting at a point N. </h3><h3>
Therefore, in-center of the triangle is point N.</h3>
Answer:
- 112 ft
- 3 - 7 seconds interval
Step-by-step explanation:
<u>Given function:</u>
<u>The height of the platform is the y-intercept, when t = 0:</u>
- f(0) = - 16*0 + 96*0 + 112 = 112 ft
The ball's height is decreasing once it reaches the maximum, which is at vertex.
<u>The vertex is at x = -b/2a:</u>
<u>The ball hits the ground when f(t) = 0:</u>
- - 16t² + 96t + 112 = 0
- t² - 6t - 7 = 0
- (t - 7)(t + 1) = 0
- t = 7 (positive root)
The interval is between 3 seconds and 7 seconds
