Prove that cos^3x+3cos2x= 4 (cos^6 x-sin^6x)
gavmur [86]
But this isn't true... If x=\dfrac\pi2, you have

\cos^3\dfrac\pi2+3\cos\pi=0-3=-3
4\left(\cos^6\dfrac\pi2-\sin^6\dfrac\pi2\right)=4(0-1)=-4

but of course -3\neq-4.

Mrs. Gargantua thinks she finally may have found
docker41 [41]

Answer:

She should used 4.5 ounces of the 4% and 1.5 ounces of the 20%.

Step-by-step explanation:

x = amount of 4% fuel

6 - x = amount of 20% fuel

0.04x + 0.2(6 - x) = 0.08(6) Multiply both sides by 100 to remove the decimals

4x + 20(6 - x) = 8(6)

4x + 120 - 20x = 48

-16x + 120 = 48

-16x = -72

x = 4.5

She should used 4.5 ounces of the 4% and 1.5 ounces of the 20%.
