To calculate the area between both curves, we must calculate the following integrals:
int a-b [f (x)] dx
int a-b: integral from a to b
f (x): function
Enter [0, (π / 2)]
int 0-π / 2 [(7 cos (x) -7sin (x))] dx = int 0 -π / 2 [(7 cos (x)] dx + int 0-π / 2 [-7sin (x) )] dx
Calculated:
int 0-π / 2 [(7 cos (x)] dx = 7 (sin (π / 2) - sin (0)) = 7 (1-0) = 7
int 0-π / 2 [-7 sin (x))] dx = 7 (cos (π / 2) - cos (0)) = 7 (0-1) = - 7
int 0-π / 2 [(7 cos (x) -7sin (x))] dx = 7 + (-7) = 0
answer
the area of the region bounded by the x-axis and the curves y = 7sin (x) and y = 7 cos (x) where x∈ [0, (π / 2)] is
A=0

Answer: 34,560
Step-by-step explanation:
Total crayons of different color = 12
Total children = 3
Each child will get 4 crayons.
Number of combinations of selecting <em>r</em> things out of <em>n</em> things = 
The number of ways of selecting the first 4 crayons for first child = 
Colors left = 12-4 =8
Now, the again selecting 4 colors out of 8 for second child = 
Colors left =4
Number of ways of selecting 4 colors out of 4 for third child =1
Total number of ways = 495 x 70 x 1 = 34650 [By fundamental principle of counting]
Hence, the total number of ways = 34,560.
Answer:
- (2^9)
Step-by-step explanation:
-(2^6)(2^3)
We know a^b * a^c = a^( b+c)
- ( 2 ^ (6+3))
- (2^9)
