Answer:
Step-by-step explanation:
This is right triangle trig. The reference angle is 12 in one case and 60 in the other, but the horizontal distance doesn't change in either one, and neither does what you are looking for, which is the height of the balloon in both cases of the angle differences. And if you're looking for the difference in the height, you'll find both and subtract the smaller from the larger.
The height is across from the reference angle and the horizontal distance is adjacent to the reference angle, so the trig identity you want is tangent. Set up according to the angle measure of 12 degrees:
and
280 tan(12) = x
x = 59.5 ft
Now for the angle measuring 60 degrees:
and
280 tan(60) = x
x = 484.9
The difference between the two heights is 425.5 feet.
The rate is 0.30 km/min. The rate in linear functions, which must be assumed with only two given points can be traced to calculating the slope (m) of the line or rate.
m= (y2-y1) / (x2-x1)
with our two given points (x,y) we fill out the equation as:
M= (12 - 0) / (40 - 0) or M = 12/40 = 0.3
keeping our units intact 12 km / 40 min so the answer is 0.3 km/min
B (if annual interest),
200+12%=224
224+12%=250.88

And a quotient. D.
In a division you have:
Quotient = Dividend / Divisor
The result is called the Quotient, the number at the top of the division is called the dividend and the number below is the divisor.
