Answer:
1
Step-by-step explanation:
f(x) = e^(8x⁵−8x)
Since f(x) is continuous:
lim(x→1) f(x) = f(1)
lim(x→1) f(x) = 1
-4/5
r=x/2
a=2x
ar²=-1/16
x^3=-1/8
x=-1/2
sn=a/1-r
=-4/5
1yr 47,000, 2nd yr 48,880, 3rd yr 51,617.28, 4th yr 57,346.7981 or 57,346.80
1yr 47,000
2nd yr 47,000 x 4% = 48,880
3rd yr 48,880 x 5.6% = 51,617.28
4th yr 51,617.28 x 11.1% = 57,346.7981 or 57,346.80
first 7 then 5 and 27.5
1. h₀ = 70
v₀ = 0 since the rock is dropped it has no initial velocity
when the rock hits the ground the height = 0
plug into the formula
0 = -4.9t² + 0(t) + 70
0 = -4.9t² + 70
Add 4.9t² to both sides
4.9t² = 70
Divide both sides by 4.9
t² = 14.2857142857
Take the square root of both sides
t = 3.7796447301
t ≈ 3.8 seconds
