Answer:

  • 9/5

Step-by-step explanation:

<u>Associative property of multiplication:</u>

  • (ab)c = a(bc)

It makes calculations easier by by grouping easy ones. Applying to given expression:

  • 6(3/2 * 1/5) =
  • (6*3/2)*(1/5) =
  • 9*1/5 =
  • 9/5

Answer:

  (x, y) = (0, -26)

Step-by-step explanation:

The y-intercept is the y-value that corresponds to x=0. Here, we have a table that has x-values that differ by 12 and 24. We want to find the y-value that corresponds to an x-value 24 less than the lowest one on the table:

  24 -24 = 0

We notice that when x-values differ by 24, the y-values differ by 10 -(-8) = 18. So, the y-value we want is 18 less than the lowest one in the table:

  y = -8 -18 = -26

The (x, y) coordinates of the y-intercept are (0, -26).

He used 17/3 feet = 5 and 2/3 feet

Step-by-step explanation:

∵ He bought 9 and 1/3 feet = 28/3 feet

∵ He had 3 and 2/3 feet left = 11/3 feet

∴ He used = 28/3 - 11/3 = 17/3 feet = 5 and 2/3 feet

Given that cos(theta) = 8/17 and that theta lies in Quadrant IV, what is the exact value of sin 2(theta)?
Deffense [45]

Answer:    -\frac{240}{289}

=========================================================

Explanation:

Use the pythagorean trig identity \sin^2(\theta)+\cos^2(\theta) = 1 and plug in the fact that \cos(\theta) = \frac{8}{17}\\\\

Isolating sine leads to \sin(\theta) = -\frac{15}{17}\\\\. I'm skipping the steps here, but let me know if you need to see them.

The result is negative because we're in quadrant 4, when y < 0 so it's when sine is negative.

Therefore,

\sin(2\theta) = 2\sin(\theta)\cos(\theta)\\\\\sin(2\theta) = 2*\left(-\frac{15}{17}\right)*\left(\frac{8}{17}\right)\\\\\sin(2\theta) = -\frac{240}{289}\\\\
