How much money has to be invested at 2.3% interest compounded continuously to have $41,000 after 17 years?
Llana [10]
For this, we have to calculate how much money has to be invested at 2.3% interest compounded continuously to achieve $41,000 after 17 years

Formula: A= P * ( 1+r)^t
A= $41,000
r=0.023
t= 17
<span>41,000= P * (1+0.023)^17
</span>41,000= P * (1.023)^17
41,000= P * 1.4719
P= 41,000 : 1.4719
P= $27,731.59
Therefore, the answer is C. $27,731.59 
I checked by doing the opposite, and I got $41,000.01, which is the closest to the question<span>

Please solve!!!!!!!!!!!
vivado [14]

Answer:

A=8x-8

B=5x+25

A=B(BEING corresponding angles)

8x-8=5x+25

8x-5x=25+8

3x=33

x=33/3

x=11

now 8x-8= 8×11-8

= 88-8

=80

5x+25= 5×11+25

=55+25

= 80

A=B#
