Answer:
x = - 2 or x = 4
Step-by-step explanation:
To find the x- intercepts let f(x) = 0, that is
(x - 4)(x + 2) = 0
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 2 = 0 ⇒ x = - 2
The x- intercepts are at x = - 2, x = 4
Consecutive numbers differ by one. So, if
is the first, the three numbers are

The sum of the first and third integer is

Answer:

Step-by-step explanation:
To solve this, all we need to do is draw a triangle.
From the
we can deduce that 
From that, we can draw our triangle as we know that tan(x) is the opposite side over the adjacent side. Attached is that triangle. Through the Pythagorean Theorem, we can find that the hypotenuse of this right triangle is 
Now all we need to do is take the sin of this triangle, which is the opposite side over the hypotenuse
This gives us the value of
which is our answer.
No, it is not. If you see closely, the number 5.2 is not 52. 60 is greater than 5.2.
