Answer:
20:5
Step-by-step explanation:
find how many parts (5)
25/5=5 (1 part)
5*4=20
5*1=5
The region inside one leaf of r the area of the region is pi.20.
r =cos5θ
cos5θ =0
5θ=pi/2 ,5θ=3pi/2
θ=pi/10,θ=3pi/10
area of one leaf = ∫[pi/10 to 3pi/10](1/2)r2dθ
= ∫[pi/10 to 3pi/10](1/2)(cos5θ)2dθ
= ∫[pi/10 to 3pi/10](1/4)(1+cos10θ)dθ
=[pi/10 to 3pi/10](1/4)(θ+ (1/10)sin10θ)
=(1/4)((3pi/10)+ (1/10)sin3pi) -(1/4)((pi/10)+ (1/10)sinpi)
=(1/4)(3pi/10) -(1/4)(pi/10)
=(1/4)(2pi/10)
=pi/20
area of one leaf =pi.20.
Region area (calculus) Region area. The non-negative function given by y = f(x) represents a smooth curve on the closed interval [a, b].The area through the curve of f(x), the x-axis, and the perpendicular lines x = a and x = b The bounding region shown in Figure 1 is given by.

It’s B because C is too much and A is to little for the correct answer
Using the 30-deg angle, you can find the side of the parallelogram to be 8 cm.
The height of the parallelogram is 4 cm.
A = 8 cm * 4 cm = 32 cm^2
Total amount: 16
Red socks: 4
Probability of picking a red sock 4/16
If we take a red sock out and do not replace it, we are left with a total of 15 socks.
Blue socks: 6
So the probability of picking a blue sock will be 6/15
Multiply:
4/16 * 6/15 = 24/240 = 1/10
