olchik [2.2K]

Answer:

A signal from the transmitter will be picked up through out the 57.38 mile drive

Step-by-step explanation:

The radius of the transmitter = 63 miles

Therefore, since both the location 38 miles north and the location 43 miles east of the transmitter are within the the radius, the transmission of the transmitter will be received through out the straight line journey

The length of the travel path is given by;

Distance from 38 miles north of the transmitter to distance of 43 miles east of transmitter = \sqrt{38^2+43^2}  = 57.38 \, miles.

At the age of 22, Vicki opened an IRA. At the beginning of each year, she deposits $1100 into her IRA, which earns 9% annual int
jeyben [28]

Answer:

$51,557.00

Step-by-step explanation:

1100 times 9% = 99 a year

99 times 43 = 4257

1100 times 43 =47,300

then you add 47,300 + 4257 = 51,557

you take your total that she put into the ira and multiply it by 9%

then you multiply that total by the number of years before she retires which is 43

so 99 times 43 = 4257

then you will multiply how much she put in the ira at the beginning of the year which is 1100 by the 43 years before she retires which is 47,300

then you add your totals together

4257 + 47,300 = 51,557
