Answer:
<em>0m</em>
Step-by-step explanation:
Before the ball is thrown, it is at the ground level. At the ground level, the height is zero. Substitute h = 0 into the equation;
h(x)=-x^2+10x-16
0=-x^2+10x-16
x^2-10x+16 = 0
Factorize
x^2-8x-2x+16 = 0
x(x-8) - 2 (x-8) = 0
x-2 = 0 and x - 8 = 0
x = 2 and 8
At x = 2
h(2) = -2^2 + 10(2) - 16
h(2) = -4 + 4
h(2) = 0
<em>Hence the height of the ball at the time it is thrown is 0m</em>
Hi!
When we divide a fraction for a fraction we have to multiply the first fraction for the opposite of the second (the one we're dividing for).
Let's do an example.
16/8 : 4/6 = 16/8 * 6/4
Where necessary you can do cross-semplifying.
So, 16 and 4 can be divided both for 4.
8 and 6 both for 2.
So we have 4/4*3/1
You can also semplify numerator and denominator...
4/4 = 1
1*3 = 3
1. Vertical
2. Adjacent
3. Complementary
4. 72
5. X= 33
Answer:
A
Step-by-step explanation:
Calculate the midpoint using the midpoint formula
[ 0.5(x₁ + x₂ ), 0.5(y₁ + y₂ ) ]
with (x₁, y₁ ) = (- 1, 5) and (x₂, y₂ ) = (5, 5)
midpoint = [ 0.5(- 1 + 5), 0.5(5 + 5) ]
= [ 0.5(4), 0.5(10) ] = (2, 5 ) → A
