Answer:
(0, 0)
Step-by-step explanation:
f(x) = (x-4)(x+4)
Let f(x) = 0
Therefore,
(x-4)(x+4) = 0
x - 4 = 0 or x + 4 = 0
x = 4 or x = - 4
Hence x - intercepts are (-4,0) & (4, 0)
Mid point of x - intercepts = (- 4 + 4) /2, (0+0)/2= 0/2 , 0/2 = (0, 0)
<u>Change</u> of PE over a height of 10m = M G H = (10) (9.8) (10) = 980 joules.
When the box hits the bottom, it has 980 joules <u>less</u> PE than it had
before it started dropping.
(As well as 980 joules <u>more</u> kinetic energy.)
Perimeter of the new triangle is 576 ft
Step-by-step explanation:
- Step 1: Given the perimeter of the right triangle = 72 ft. Find new perimeter.
Perimeter of the triangle = sum of the sides = a + b + c = 72
Each side is multiplied by 8, so new sides are 8a, 8b, 8c
⇒ New perimeter = 8a + 8b + 8c = 8(a + b + c) = 8 × 72 = 576 ft
