Her first rate was faster. The 10 minutes with a change in elevation of -200ft.
In order to solve this you need to have the same minutes. In this problem, I just simply took the 10 minutes and the -200ft and doubled it. Now both rates have 20 minutes. The first rate would have gone -400ft in 20 minutes while the second rate was only -300ft in 20 minutes. I hope this wasn't confusing, and I'm willing to explain more.
Answer:
x+3, y-4
Step-by-step explanation:
You are moving the triangle 3 to the right, so x+3, an 4 down, so y-4.
Answer:
Step-by-step explanation:
Volume of cylinder = π times r^2 times h (height)
8,685.9 = π times r^2 times h
To find the radius, divide the diameter by 2.
19.2 / 2 = 9.6
8,685.9 = 3.14 x 9.6^2
3.14 x 9.6^2 = 289.38 (estimated)
8,685.9 = 289.38
Divide 289.38 by 8,685.9.
289.38 / 8,685.9 = 0.033316064
I hope this is right?!!
That trinomial can't be factored. You would have to complete the square to factor it and even then your answer would be an imaginary number.
x² + x + 12 = 0
x² + x = - 12
x² + x + 1/4 = - 12 + 1/4
x² + x + 1/4 = - 11 3/4
x² + x + 1/4 = - 47/4
(x + 1/2)² = - 47/4
x + 1/2 = +/- √(- 47/4)
x + 1/2 = +/-

x = 1/2 +/-

If the constant was a negative, it would be factor-able (is that a word?).
