Answer:
Step-by-step explanation:
From the given information, consider DB=x be the height of the ship, BC= 50 m, then DE=50 m.
Now, From ΔABC,
⇒
Also, from ΔADE, DE=50 m, we have
⇒
Now, AC=AE+EC
⇒
⇒
⇒
⇒
Also, we know that EC=BD, therefore BD=21.14 meters.
Thus,the height of the ship= 21.14 meters.
Answer:
<h2><u><em>
5 and 7</em></u></h2>
Step-by-step explanation:
One number is 2 more than another. The difference between their squares is 24. What are the numbers?
(x + 2)² - x² = 24
x² + 4x + 4 - x² = 24
4x + 4 = 24
4x = 20
x = 20 : 4
x = 5
----------------------
5 + 2 = 7
check
(5 + 2)² - 5² = 24
49 - 25 = 24
24 = 24
the answer is good
yes its a function because it passes the vertical line test. Yes, it is linear because the slope is constant.
Answer:
It would take you 5/3 hours, or 1 hour and 40 minutes.
