So 8 <10 on each side do -8 then it will be X=2
The possible values of x is x > 10
<h3>How to determine the possible values of x?</h3>
The dimension of the rectangle is given as:
Length = 6
Width = x + 2
The area is calculated as;
Area = Length * width
So, we have
Area = 6 * (x + 2)
The area is greater than 72
So, we have
6 * (x + 2) > 72
Divide by 6
x + 2 > 12
Subtract 2 from both sides
x > 10
Hence, the possible values of x is x > 10

So percent means parts out of 100 so
1%=1/100
so 9/20=x/100
a hack withought using legit math is
20 times 5=100 so
9/20 times 5/5=x/100
9 times 5=45
20 times 5=100
45/100
45% is the answer
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:
subtract 17 on both sides
