Answer:
A
Step-by-step explanation:
The answer is A for Apex Precal
It is a root of the polynomial if it causes the equation to equal 0. Let's try each number. Substituting -3 for x... (-3)³ - 4(-3)² -11(-3) + 30 -27 - 36 + 33 + 30 0 Therefore, a. -3 is a root to our polynomial. You could try the rest, but I won't waste time with it. None of the others are roots, and it's multiple choice which means usually just one answer.

Answer:
Volume = 3.14 × 5² ×6 ÷ 3
volume = 157 cm³ B
Answer:
Step-by-step explanation:
f(x) = -5x + 8(7 - x)......when f(x) = 160
160 = -5x + 8(7 - x)
160 = -5x + 56 - 8x
160 - 56 = -5x - 8x
104 = - 13x
-104/13 = x
-8 = x <====
Answer:
17b
Step-by-step explanation:
Total volume of water = amount of water in each bottle x total number of bottles. The equation that relates the number of bottle of water (b) to the total volume of the water (w) in fluid ounces is w = 17b
The ounces are greater than the pints. I do hope I got what you needed and helped! :)
