Deffense [45]

Answer: Approximately d = 208.72

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

Work Shown:

Make sure your calculator is in radian mode

A quick way to check is to compute cos(pi) and you should get -1

cos(angle) = adjacent/hypotenuse

cos(x) = 200/d

cos(0.29) = 200/d

d*cos(0.29) = 200

d = 200/cos(0.29)

d = 208.715135166392 which is approximate

d = 208.72

I rounded to two decimal places since x is rounded in that manner as well. Round however else you need if your teacher instructs.

Timothy has a savings account that he started five years ago to begin saving for college. The
torisob [31]

Answer:

A. $1500.00

Step-by-step explanation:

Assuming this is a simple interest savings account.

<u>Simple interest formula</u>

I = Prt

where:

  • I = total interest
  • P = principal amount
  • r = interest rate (in decimal form)
  • t = time (in years)

Given:

  • I = $225
  • r = 3% = 0.03
  • t = 5 years

Substitute the given values into the formula and solve for P:

⇒ I = Prt

⇒ 225 = P(0.03 ×5)

⇒ 225 = P(0.15)

⇒ P = 225 ÷ 0.15

⇒ P = 1500

Therefore, Timothy started the account with $1500.00.
