Hector invests $800 in an account that earns 6.94% annual interest compounded semiannually. Rebecca invests $1,000 in an account that earns 5.45% annual interest
compounded monthly. Find when the value of Rebecca's investment equals the value of
Hector's investment and find the common value of the investments at that time. If
necessary, enter the year to the nearest tenth and the value to the nearest cent.
The value of Rebecca's investment equals the value of Hector's investment after
approximately
years to the nearest tenth. The common value of the investments is
approximately $

add all together then subtract by yhe original numbers so in this on it will be 4

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
