Answer:
f(2) =30
Step-by-step explanation:
f(1)=15
f(n)=f(n-1)*n
Put in n=2
f(2)=f(2-1)*2
= f(1) *2
= 15*2
=30
Answer:
D. vo = 125(2)^1/2
Step-by-step explanation:
Range of a projectile is the defined as the distance covered in the horizontal direction.
Range = U²sin2θ/g
U is the speed of the object
θ is the angle of launch
g is the acceleration due to gravity
If the target is 1000 ft away horizontally, range = 1000ft
θ = 45°
g = 32ft/s²
1000 = U²sin2(45°)/32
32000 =U²sin90°
32000 = U²
U = √32000
U = 125√2 m/s
If that is all the question is asking, simply solve the problem.
Divide 8 cars by 4 hours, giving you 2 cars every hour.
Answer:
B 1 1/7
Step-by-step explanation:
- 9 2/7 - ( -10 3/7)
We know subtracting a negative is like adding
- 9 2/7 +10 3/7
10 3/7 - 9 2/7
Putting this vertical
10 3/7
-9 2/7
-----------------
1 1/7
Answer:
x=5
Step-by-step explanation:
Since the sides are equal, the two base angles are equal
10x = 5x +25
5x = 25
x=5
