Answer:
x =2 and x = 6 are the x-intercepts
Step-by-step explanation:
The x -interepts mean the value of x when y=0
so
y = 0 = (x - 2)(x - 6)
Here if we solve for x, we solve the x-intercepts.
0 = (x - 2) or 0 = (x - 6)
x = 2 or x = 6
Answer:
sinQ=cosR
Step-by-step explanation:
First we need to find out the measure of ∠R.
The sum of all the angles in a triangle add up to 180. Therefore:
∠Q+∠R+∠S=180
66+∠R+90=180
∠R=180-156
∠R=24°
Since ∠Q≠∠R, sinQ≠sinR. So the first option is incorrect - let's try the second one.
sinQ=cosR
sin66=cos24
0.9135454576=0.9135454576
So the second equation is the correct relation.

Answer:
Step-by-step explanation:
The missing equation is:
Suppose f = nonnegative function whose first derivative is within (a,b) and it is continuous, Then the area of the surface generated is revolved about the x-axis:
The area of the surface revolution is:
So; if 
for ![y \ \varepsilon \ [c,d]](https://tex.z-dn.net/?f=y%20%20%5C%20%5Cvarepsilon%20%20%5C%20%5Bc%2Cd%5D)
Then; substituting a with c and b with d; f(x) also with g(y) and dx with dy;
Then;
SInce;
; Then the statement is false.
Provided that the semicircle 
isn't on ![[-1,1]](https://tex.z-dn.net/?f=%5B-1%2C1%5D)
interval.
Then, the solid generated by the revolution about the x-axis is a sphere.
However, the surface is well defined and the statement is false.
