What are the x-intercept of the graph y=(x-2)(x-6)
ziro4ka [17]

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

Which equation shows a correct relation for triangle RSQ?
son4ous [18]

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.

Determine whether the following statements are true and give an explanation or counterexample. If f is not one-to-one on the int
Natasha2012 [34]

Answer:

Step-by-step explanation:

The missing equation is:

S = \int ^b_a 2 \pi f(y) \sqrt{1 + f' (y)^2 } \ dy

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:

S = \int ^b_a 2 \pi f(x) \sqrt{1 + f' (x)^2 } \ dx

So; if  x = g(y) for y  \ \varepsilon  \ [c,d]

Then; substituting a with c and b with d; f(x) also with g(y) and dx with dy;

Then;

S = \int ^d_c 2 \pi g(y) \sqrt{1 + g' (y)^2 } \ dy

SInce;

g(y) \ne f(y); Then the statement is false.

Provided that the semicircle y = \sqrt{1-x^2} isn't on [-1,1] 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.
