F(-7)=0
Because that makes the (x+7) factor equal zero and any other factor multiplied by zero also results in zero.
Answer:
6
Step-by-step explanation:
9/1 × 2/3
(9 × 2 = 18)
(1 × 3 = 3)
18 ÷ 3 = 6
Answer:
7
Step-by-step explanation:
This a special 90° 45° 45° triangle and is an Isosceles triangle at the same time
Of one of the equal side is 7 than the other one too must be 7
Answer: e^y=x
ln(x)=y
e^ln(x)=e^y
x=e^y
That's a right triangle with hypotenuse 3000 and the height y is the side opposite the elevation angle of 15 degrees.

We can actually compute

exactly but I won't bother.
