Answer:
The shaded region is 
.
Step-by-step explanation:
The area of a circle is defined by the multiplication of the square of its radius, or half its diameter, by pi, or simply 
.
15m is the radius of the large circle, and also the diameter of the smaller circles.
The area of the shaded region will be the subtraction of the area of the two smaller circles from the area of the larger circle.
As such:
Answer:
30x-5
Step-by-step explanation:
25-5=20
20-5=15
-5 -10 -15 -20 -25
25 20 15 10 5

Answer:
cosA = 0.6
Step-by-step explanation:
Using the Pythagorean identity
sin²A + cos²A = 1 ( subtract sin²A from both sides )
cos²A = 1 - sin²A ( take the square root of both sides )
cosA = ± 
Since only the positive value is required , then
cosA = 
= 
= 
= 0.6
It is the angle where it says "A".
The slope of the line is 2, and it the equation for it is y=2x+1
