On Olga's 16th birthday, her uncle invested $2,000 in an account that was locked into a 1.75% interest rate, compounded monthly. How much will Olga have in the account when she turns 18? Round to the nearest cent.

$2070.6

Step-by-step explanation:

Step one:

given data

principal p= $2000

Rate r= 1.75% = 0.0175

time t= 18-16= 2years

Required

The final amount of the compounded principal

The compound interest formula is

A=P(1+r)^t

A=2000(1+0.0175)^2

A=2000(1.0175)^2

A=2000*1.0353

A=2070.6

The account when she turns 18 will be $2070.6

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
