Find the exact value of cos theta​, given that sin thetaequalsStartFraction 15 Over 17 EndFraction and theta is in quadrant II.
vova2212 [387]

Answer:

cos \theta = -\frac{8}{17}

Step-by-step explanation:

For this case we know that:

sin \theta = \frac{15}{17}

And we want to find the value for cos \theta, so then we can use the following basic identity:

cos^2 \theta + sin^2 \theta =1

And if we solve for cos \theta we got:

cos^2 \theta = 1- sin^2 \theta

cos \theta =\pm \sqrt{1-sin^2 \theta}

And if we replace the value given we got:

cos \theta =\pm \sqrt{1- (\frac{15}{17})^2}=\sqrt{\frac{64}{289}}=\frac{\sqrt{64}}{\sqrt{289}}=\frac{8}{17}

For our case we know that the angle is on the II quadrant, and on this quadrant we know that the sine is positive but the cosine is negative so then the correct answer for this case would be:

cos \theta = -\frac{8}{17}

Gekata [30.6K]

Answer:

Coupon B

Step-by-step explanation:

Given

Price = \$450

Coupon\ A = \$80

Coupon\ B = 20.5\%

Required

Which coupon is better

From the question, we have:

Coupon\ A = \$80

Coupon\ B = 20.5\%

Coupon B means that:

Coupon\ B = 20.5\% * \$450

Coupon\ B = 0.205 * \$450

Coupon\ B = \$92.25

By comparison:

Coupon B gives him a better buy because: \$92.25 > \$80
