Use the slope formula.
m = slope = (y2 - y1)/(x2 - x1)
m = (4 - 1)/(0 - (-1)) = 3/1 = 3
9/2 mph. You would need to multiply both by six to get exact mph, and three fourths times six is 18/4=9/2=4.5 mph
First, we should apply the present value of annuity formula. It is
and in this formula
is the present value of annuity factor.
Then, we can find the present value of the annuity by writing that,

Answer:
255 m
Step-by-step explanation:
From the given question, the surface of the water body is the reference point. And this point is assumed to be 0, so that any distance above it is positive, and any distance below is negative. This is synonymous to the number line system.
Thus,
For the aircraft, its height = +200 m
For the submarine, its depth = -55 m
So that the difference between the submarine and aircraft can be determined as;
200 - (-55)
= 200 + 55
= 255 m
The distance between the submarine and aircraft is 255 m.
