Find the exact value of cos theta, given that sin thetaequalsstartfraction 15 over 17 endfraction and theta is in quadrant ii. rationalize denominators when applicable.

Step-by-step explanation:

For this case we know that:

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

And if we solve for we got:

And if we replace the value given we got:

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:

283 square feet

step-by-step explanation:

good luck

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
