Answer:
The x-intercepts of a function are found where the graph of a function crosses the x-axis on a pair of Cartesian coordinate axes. How to Find the X-intercepts of a Function The x-intercepts of a function f (x) is found by finding the values of x which make f (x) = 0. Write f (x) = 0, and solve for x to find the x-intercepts of a function.
Step-by-step explanation:

The reduced form of the trig expression is 7/2sin²2a
<h3>Trigonometry identity</h3>
Trigonometry identities are written in terms of sine, cosine and tangent. Given the trigonometry identity
14sin² acos² a
Since sin(a)cos(a) = sin2a/2, hence
14sin²acos²a = 14[sin(a)cos(a)]²
14sin²acos²a = 14(sin2a/2)²
14sin²acos²a = 14/4(sin²2a)
14sin²acos²a = 7/2sin²2a
Hence the reduced form of the trig expression is 7/2sin²2a

Answer: x=5
Step-by-step explanation:
Distribute the 4 to the 2 and 9 and you will get (8x-36)=4.
Then you'd add the 36 to 4 to get 40.
Lastly you'd divide 8 and 40 to get 5. Hope this helps!!!
25 pi
Step-by-step explanation:
If the circumference equals 10pi
And to calculate the circumference is pi multiplied by diameter then the diameter must be 10
The radius is half the diameter so it is 5
To calculate the radius, you have to multiply pi by the radius squared
Which is pi × 5^2
So the answer is 25 × pi
And simply put : 25pi
