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

HELP!!!! A quarter circle is attached to the side of a square as shown.
Paul [167]

Answer:

28.56 m²

Step-by-step explanation:

What we need to do for the quarter circle is use the following formula: 1/4(πr²)

(4 * 4) + 1/4(3.14 * 4²)

16 + 1/4(3.14 * 16)

16 + 1/4(50.24)

16 + 12.56

28.56 m²

The best approximation for the area of this figure is 28.56 m².

Suppose that triangle TUV is an isosceles with the base VU.
vekshin1
Set them equal to each other and solve
3x + 39 = 4x +34
-x=-5
X=5
Plug it in
3(5) + 39 = 54
4(5) +34 = 54
For the final angle ,
54 + 54 = 108
180-108 =72
The angle measures are 54,54, and 72

Find 40% of 68 please
quester [9]
To find 40% of 68 
you simply divide 40% by 100 and multiply by 68

40/100 x 68 = 32.64

32.64 is 40% of 68.

The same steps can be used to find any percentage of any number.
simply divide the percentage given by 100 and multiply by the total number.
