For this case we must find the x-intercepsts of the following function:
For this we do , that is: . So:
The values of "x" that comply with equality are:
Thus, the x-intercepsts of the function are:
Answer:

We have given measure of angles of the triangle are in ratio 4 : 7 : 9 and here we need to find the measure of largest angle of a ∆.
Let, the three angles of a triangle be 4x, 7x, 9x.
We know that, Sum of all angles of a triangle is 180°.
4x + 7x + 9x = 180°
⇛20x = 180°
⇛x = 180°:20
⇛x = 9°
Now, finding largest angle by putting the value of “x”
- 4x = 4(9) = 36°
- 7x = 7(9) = 63°
- 9x = 9(9) = 81°
Hence ,the measure of largest angle is 81°.

Answer:
325 miles. If one inch is 65 miles and the two locations are 5 inches apart, 65 x 5 is 325.
Fun fact: Minneapolis to St. Cloud in reality is only 70 miles. ;)
Answer:
30/100 or 3/10
Step-by-step explanation:
A percent is out of 100. So since 30 is an even number then it would be 30/100 or 3/10.
Step-by-step explanation:
there is a nice formula for the height in a right-angled triangle :
h = sqrt(p×q)
h being the height to the 90° angle, p and q being the segments (left and right of the height) of the Hypotenuse.
so, in our case
x = sqrt(25×144) = 5×12 = 60
