Answer:
h(x) = -16x² + 192x + 208
784ft
6 sec
13 sec
Step-by-step explanation:
a)
h(x) = -16x² +vx + h
here v represent velocity
represent initial height of launch
h(x) = -16x² + 192x + 208
b)
h(x) = -16x² + 192x + 208
here a = -16
b = 192
c = 208
x = -b/2a
= -192/2(-16)
= 6
plug this value in the equation
h(x) = -16(6)² + 192(6) + 208
= 784ft
e)
Plug h(x)=0 in the equation
0 = -16x² + 192x + 208
divide equation by -16
x² - 12x - 13 = 0
Factors
1x * -13x = -13
1x - 13x = -12
Factorised form
x² - 12x - 13 = 0
x² + x - 13x - 13 = 0
x(x+1) -13(x+1) = 0
(x+1)(x-13) = 0
x = -1
x = 13
Since time can not be negative so we will reject x = -1
Answer:
around 230
Step-by-step explanation:

691÷3= 230.33333333
You bought 2 because if you add $7.90 and $2.00 the coupon you would get $9.90 so then you multiply $4.95 by 2 and you get $9.90 the exact amount we had before
Answer:
20.4 ft
Step-by-step explanation:
Since they're similar triangles (same shape, but not necessarily the same size), then you can set them up as fractions to find the missing measure.
6/9.7 = ?/33
A quick way to do use this setup is to multiply 33 by 6, then divide by 9.7.
This gives you 20.4 ft
