This question needs more information like where point E is but I'm going to assume that point E is directly below point D

With that assumption, angle EDF should be (90°- 25°) which is 65°

tan 65° = opposite/adjacent
tan 65° = 10 yd/ DE
DE = 10 yd/tan 65°
DE = 4.7 yd (to the nearest tenth)

Remember to include a picture next time for greater clarity :)

Citrus2011 [14]

Answer:

30feet/second

Step-by-step explanation:

The rate in feet per seconds of the diver will be the speed of the diver.

Speed is the rate of change in distance of a body.

Speed = Distance/Time

Given distance or height of drop = 450feet

Time = 15seconds

Rate of change in distance = 450/15

Rate of change in distance = 30feet/second

Five years ago, you invested $475 in corporate stock. You received dividends of $10 at the end of each quarter for two years. Yo
RUDIKE [14]

The rate of return earned on the investment of $475 five years ago in the corporate stock is 312.63%.

<h3>What is the rate of return?</h3>

The rate of return is the net gain or loss of an investment expressed as a percentage of the investment's initial cost.

It is given by the formula,  R= {Vf - Vi}/{Vi} x 100.

Where:

R = Rate of return

Vf = final value, including dividends and interest

Vi = initial value

<h3>Data and Calculations:</h3>

Investment cost = $475

Dividends received:

1st two years = $80 ($10 x 8)

Three years = $180 ($15 x 12)

Total dividends received = $260 ($80 + $180)

Total revenue from sale = $1,700

Total proceeds = $1,960 ($1,700 + $260)

Total return = $1,485 ($1,960 - $475)

Rate of return = 312.63%  ($1,485/$475 x 100)

Thus, the rate of return is 312.63%.
