Answer:
90·
Step-by-step explanation:
The quadratic model is f(x) = -5x^2 + 200.
f(x) = 50 meters
x = time in seconds
50 = -5x^2 + 200
5x^2 = 150 // Here, divide both side by 5
x^2 = 30
x =

seconds
Or approximately 5.48 seconds
Answer:
yes
Step-by-step explanation:
(10, 4):
x=10
y=4
3(10) - 5(4) = 10
30 - 20 = 10
<span>Let us take the number as 'A'
Given 10 times 'A' is 0.08
So 10 X A =0.08
10A =0.08
A=0.08/10
=0.008
Answer is 0.008</span>
