Answer:
75+150=225 in^2
Step-by-step explanation:
Separate each layer.
Area1+Area2= Total area
A1= a*b*d
A2=a*c*d
A1=5*5*3=75 in^2
A2=5*10*3=150 in^2
75+150=225 in^2
Yes, they all have 4 corners.
You should be able to set up a proportion between the sides something like (18+x)/x=(56+21)/56
Answer:
m=0.5 b=1
Step-by-step explanation:
M is the increase in value by one square point via b.
B is the y axis beginning position.
I could be wrong, though.
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
I am not doing the rest I only did one just to help you understand a bit more
