The answer is 9.2, because when the number behind the number being rounded is 5 or above, you round up. if the number was 9.14, it would be rounded down to 9.1 :)
Answer:
√(p²-4q)
Step-by-step explanation:
Using the Quadratic Formula, we can say that
x = ( -p ± √(p²-4(1)(q))) / 2(1) with the 1 representing the coefficient of x². Simplifying, we get
x = ( -p ± √(p²-4q)) / 2
The roots of the function are therefore at
x = ( -p + √(p²-4q)) / 2 and x = ( -p - √(p²-4q)) / 2. The difference of the roots is thus
( -p + √(p²-4q)) / 2 - ( ( -p - √(p²-4q)) / 2)
= 0 + 2 √(p²-4q)/2
= √(p²-4q)
I'd say angle A = angle B
arc tangent (angle B) = 150 / 555

angle B = 15.124 degrees
By the way 555 feet is the height of the Washington Monument.

Answer:
B
Step-by-step explanation:
Use the given functions to set up and simplify f(-3x)
substitute x with -3x
-2 (-3x) =6x remember a - x - = +
6x +5
