Answer:
f(x) = 4x² - 40x + 84
Step-by-step explanation:
4(x - 7)(x - 3) = 0
4(x² - 3x - 7x + 21) = 0
4(x² - 10x + 21) = 0
4x² - 40x + 84 = 0

Answer:
37.35 in
Step-by-step explanation:
The volume of a cone is given by the formula ...
V = (π/3)r²h
where r is the radius of the base and h is the height. We want to find the diameter of the base, so we can rewrite this in terms of diameter and solve for d. Please note that the height is given in millimeters, not inches, so a conversion is necessary.
V = (π/3)(d/2)²h
12V/(πh) = d²
d = 2√(3V/(πh)) = 2√(3(2.2×10^4 in^3)/(π·1530 mm/(25.4 mm/in))
= 2√(1.6764×10^6/(π·1.53×10^3) in^2)
d ≈ 37.35 in
The base diameter of the cone is about 37.35 inches.
Answer:
C.
Step-by-step explanation:
When you check the point that is on X, it is a little over halfway to the point 1,2. It would be like 1,1.5 or 1,1.6.
5/3 is the equivalent to 1.6 so that answer would make the most sense.
