Answer:
1. Volume of a cone: 1. V = (1/3)πr2h 2. Slant height of a cone: 1. s = √(r2 + h2) 3. Lateral surface area of a cone: 1. L = πrs = πr√(r2 + h2) 4. Base surface area of a cone (a circle): 1. B = πr2 5. Total surface area of a cone: 1. A = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))
Step-by-step explanation:
1. Volume of a cone: 1. V = (1/3)πr2h 2. Slant height of a cone: 1. s = √(r2 + h2) 3. Lateral surface area of a cone: 1. L = πrs = πr√(r2 + h2) 4. Base surface area of a cone (a circle): 1. B = πr2 5. Total surface area of a cone: 1. A = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))
Find factors of -5 that, when added together, will give 4
x² + 4x - 5
x 5
x -1
(x + 5)(x -1)
Using the FOIL method (First, Outside, Inside, Last), we can get the question again.
x(x) = x²
x(-1) = -x
5(x) = 5x
5(-1) = -5
x² - x + 5x - 5
x² + 4x - 5
(x + 5) (x - 1) is your answers
however, i believe it is only asking for one. Therefore, because (x - 1) is a choice, (x - 1) should be your answer
hope this helps
Using a savings interest calculator, I found that either way your savings grow by exactly $1,020.20, so they share the same interest.
