It is a.1
(1+5) - 2(4(1)-1) = 0
(6) - 2(3) = 0
6 - 6 = 0
0=0
Answer:
14 pushups per min
70 pushups in 5 min
Step-by-step explanation:
The circumference of every circle is (pi) times (diameter).
The diameter is (2 x radius), so we can write
Circumference = (pi) x (2 x radius) .
The question gives us the circumference, and the number to use for (pi).
I shall now pluggum in:
(31.4 cm) = (3.14) x (2 x radius)
Divide each side by 3.14: (31.4 cm)/(3.14) = 2 x radius
Divide each side by 2 : (31.4 cm) / (2 x 3.14) = radius
5 cm = radius
Answer: 13 sheets of paper
Step-by-step explanation:
We are given the dimensions of the box and the wrap paper:
Box:

Warp paper:

Now we need to find the surface area of the box and the area of the wrap paper:
Box:




Warp paper:

Dividing the area of the box by the area of the paper:

This means Angel's dad needs to purchase 13 sheets of wrapping paper.
T = 0
=> Q = 0
t = x
=> Q = arcsin(x/a)
rest it just simple integration of trigonometric function
