Step-by-step explanation:
Ends in 4
Answer:
4.80
Step-by-step explanation:
17+5.50h=11+6.75h
- subtract 11 from both sides
-subtract 5.50 from both sides
-divide to get h alone
the value of r of the geometric series n=11.3(0.8)n-1
General formula for nth term of any geometric series is
Here 'r' is the common ratio
a_1 is the first term of the series
Now we compare the given formula with general formula
Compare with
The value of r= 0.8
Answer:
6.46
Step-by-step explanation:
h(t) = (1/2) + v0t + h0
Origin is at surface of water (h = 0), up is positive.
a = -g = -9.8 m/
v0 = 25 m/s
h0 = 50 m
h(t) = -4.9t2 + 25t + 50
Find t when
7 = + 25t + 50
- 25t - 43 = 0
t = [1/(2*4.9)] [25 ±√( + 4*4.9*43)]
t = (0.102)(25 ± 38.312)
t > 0 ⇒ use only the positive square root
t = (0.102)(25 + 38.312) ≅ 6.46 s
It is 7m above the water at about 6.46 s
No, because 9 > 8, and 3.098 is > 3.089
