Answer:
the first option
Step-by-step explanation:
hope it helps!!!
Falling at the rate of 2.5 m/s for 45 seconds, the anchor fell
(2.5 m/s) x (45 s) = 112.5 meters .
If it wound up only 40 meters underwater, then it must have fallen
(112.5 m - 40 m) = 72.5 meters
from its storage position on the big cruise ship,
before it ever reached the water.
Since it was falling at the rate of 2.5 m/s, it took
(72.5 m) / (2.5 m/s) = 29 seconds
to get down to the water surface after it started dropping.
I used the distance formula, the answer is 15
Plug (-6,-5) into the equations to see wich one fits.
y=9/2 x +22
(-5)=9/2(-6) +22
-5=9*-3+22
-5=-27+22
-5=-5
that's how B is the answer. hope this helps :)
26 x 72 = 1872
40 + 420 + 12 = 472
1872 - 472 = 1400 (the answer)
