Answer:
Below in bold.
Step-by-step explanation:
speed = distance / time
2.4 * 10^4 = 3.2 * 10^6 /time
Time = 3.2 * 10^6 / 2.4 * 10^4
= 3.2/2.4 * 10^(6-4)
= 1.3333.. * 10^2 hours
= 133 hours ( to 3 significant figures).
-6, -4, -2, 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32
Answer: 32
Ok, this is a ratio problem; the ratio of the length to width is constant (and therefore equal): 4 /6 = 15 / x Now, with a ratio, we may do any allowable algebra operation: cross-multiply, invert both sides, multiply or divide both sides by the same amount, etc. Let's cross-multiply: 4x = (15)(6) x = 90/4<span> x = 22.5 in. </span>
Formatting is kind of messed up. I'm assuming the differential equations is dy/dx = 6x
You need to get all the x's on one side and y'all on the other.
dy =6x dx
Integrate both sides.
y = 3x^2 + C
Now plug in the given values
y(0) = 4 = 3(0)^2 + C
C = 0
y = 3x^2
Plug 1 in for x to find the value of y(1)
y(1) = 3(1)^2 = 3
1) p + 8
Substitute 2 in for the variable.
2 + 8 =
2) 3p
Substitute 2 in for the variable.
3(2) =
3) 16 - p
Substitute 2 in for the variable.
16 - 2 =
4) -12 ÷ p
Substitute 2 in for the variable.
-12 ÷ 2 =
