4.6, 6.41, 6.46
Hope this helps her!
A. Convert to vertex form:-
= -0.8(x^2 - 4x) + 6
= -0.8 ((x - 2)^2 - 4)) + 6
= -0.8(x - 2)^2 + 9.2
Maximum height of the ball is 9.2 feet Answer
b. horizontal distance at this height = 2 feet. Answer
c. this distance will be the positive root of f(x) = 0
-0.8(x - 2)^2 = -9.2
(x - 2)^2 = 11.5
xi-2 = sqrt 11.5 = 3.39
required distance = 5.39 = 5.5 feet answer
Answer:
220
Step-by-step explanation:
First find out what 10% is
To get to 10 from 100, we divide by 10
Now do the same with 200
200/10 = 20
100% + 10% = 110%
200 + 20 = 220
That's my answer!
Hope this helps!
