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,

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

3 ft<br> 4 ft<br> What is the length of the hypotenuse

elena-s [515]

The length of the hypotenuse is 5ft
a^2+b^2=c^2
3^2+4^2=c^2
9+16=c^2
c^2=25
sqrt c^2= sqrt 25
c=5
Therefore, the length of the hypotenuse is 5th

Isabelle ordered 3 flower arrangements to send to her sisters. Each arrangement, weighs 6 2/3 pounds. What was the total weight

Liono4ka [1.6K]

Answer: 20 pounds.

Step-by-step explanation:

We know the weight of each flower arrangement (each one weighs 6 2/3 pounds) and the total number of flower arrangaments Isabelle ordered (3 flower arrangements).

To make the calculus easier, we can rewrite the mixed number 6 2/3 as a decimal number:

Divide the numerator 2 by the denominator 3 and add the result to the whole number 6:

$(6+0.666)lb=6.666lb$

If 1 arrangement weighs 6.666 pounds, the total weigth of 3 arrangements can be calculated by multiplying 6.666 pounds by 3:

$weight_{(total)}=(6.666lb)(3)\\weight_{(total)}=20lb$
