Answer:

Step-by-step explanation:
h= 1000 ft
dx/dt= 232 ft/sec
D= 1600 ft
First, we have to find a distance x ( shown in the figure)
applying pythagorus theorem
D^2= h^2+x^2................1
x^2= D^2-h^2
= 1600^2-1000^2
x^2= 1560000
x=1248.99 m
Now we can find out how fast the aircraft is receding from the trawler
( notice that the height is not changing)
so differentiating equation 1 w.r.t t we get

2DD'= 2hh'+2xx'

now putting values we get


Answer:
$54.73 monthly installment for 6 months.
Step-by-step explanation:
Kevin just bought a refrigerator for $469.
He paid $140.6 in down payment and will pay the rest in equal installments.
If Kevin does not have to pay any interest and he will pay the rest amount in 6 months with monthly installments,
Then, the value of each installment will be =
Dollars. (Answer)
Answer: Side a equals 19.5 metres
Step-by-step explanation: Consider the right angled triangle as shown in the picture attached. The triangle has been drawn with angle measuring 43 degrees, side c (line AB) measuring 26.7 m and side a (line CB) is yet unknown.
A right angled triangle can be solved if at least one side and an angle are available. In this question we shall apply the trigonometric ratios since we have one angle which shall be the reference angle (43°). Also we have an hypotenuse (the side facing the right angle) and an unknown side which is the adjacent (which lies between the right angle and the reference angle).
Cos B = Adjacent/Hypotenuse
Cos 43 = a/26.7
Cos 43 x 26.7 = a
0.7314 x 26.7 = a
19.52714 = a
a ≈ 19.5 (rounded to the nearest tenth)
Therefore the length of side a equals 19.5 metres.
