At the beginning of year 1, Matilda invests $450 at an annual simple interest rate of 5%. She makes no deposits to or withdrawal
Nataliya [291]
Given:
Initial investment 450
annual simple interest rate of 5%

Simple interest = Principal * interest rate * term
Simple interest = 450 x 0.05 x 14
Simple Interest = 315

Balance after 14 years: 450 + 315 = $765

We can use compounding interest, compounded once a year.

Total balance = Principal * (1 + interest rate / number of compounding)^(# compounding * term)

Total balance = 450 * (1.05)¹⁴
Total balance = 450 * 1.98
Total balance = 891

Based on these scenarios, the formula that will be used is the second formula, compounding interest formula. The balance at the beginning of year 15 is $891.

I used 14 as the number of years because the problem states at the beginning of year 15. This means 15 has not yet begun and interest is not yet earned.

swat32

Answer:

A. m∠ 2= 41°

B. m∠4 =61°

Step-by-step explanation:

Compliment means that the two angles will add up to 90°, and Supplement means to add up to 180°.

A. m∠1 + m∠2 = 90°

49°+ m∠2 = 90°

m∠2 = 90° - 49°

m∠2 = 41°

-----------------------------------------------------------------------------

B. m∠3 + m∠4 = 180°

119 + m∠4 = 180°

m∠4 = 180° - 119°

m∠4 = 61°

------------------------------------------------------------------------------

I hope you understand the topic now.
