Answer:
(A) -4 and -2
Step-by-step explanation:
The constant in the function tells you f(0) = 5.
You know that the positive leading coefficient means the value of f(x) will be negative for x-values smaller than some number. The offered answer choices indicate the value x = -4 is a lower bound on the value of c. So, -4 < c < 0, for sure.
To further refine the interval, you would need to know f(-2) and/or f(-1).
f(-2) = (-2)³ -2(-2) +5 = -8 +4 +5 = 1
Then -4 < c < -2.

Answer:
(D) 20
Step-by-step explanation:
Since this triangle is a right triangle, we can use the pythagorean theorem which is a^2 +b^2 = c^2 (where a is the legs of the triangle and c is the hypotenuse.) For this triangle using the pythagorean theorem we can say that 12^2 +16^2 = x^2. When we simplify this equation we get 144+256=x^2. When we simplify this we get x^2=400. When we take the square root of x we get that x = √400 = 20. The answer is (D) 20.
