Answer: 42.21 km
Step-by-step explanation:
We can solve this using trigonometry, since we have the following data:
is the the angle of elevation
is the horizontal distance between the plane and the radar station
is the hypotenuse of the right triangle formed between the radar station and the airplane
Now, the trigonometric function that will be used is <u>cosine</u>:
because 
is the adjacent side of the right triangle
Finding :
30% of 50,400 = 30240.
Therefore the percentage loss is 30% over the course of 3 years.
Answer:
17
Step-by-step explanation:
Since we are evaluating <em>g(x)</em> for g(4), we would substitute <em>x</em> in the equation with 4.
<em>x</em>² + 1
(4)²+ 1
16 + 1

Answer:
The inequality can be any number less than 10.
Step-by-step explanation:Like 9,8,7,6,5,4,3,2, and 1
Answer:
3. f(12) = -10; f(37) = -60
4. f(12) = -102; f(37) = -352
Step-by-step explanation:
3. Put the numbers in the formula and do the arithmetic:
f(12) = 12 -2(12-1) = 12 -22 = -10
f(37) = 12 -2(37-1) = 12 -72 = -60
__
4. The explicit formula for an arithmetic sequence with first term a1 and common difference d is ...
an = a1 +d(n -1)
Your sequence has a first term a1=8 and a common difference d=-10.
As above, fill in the numbers and do the arithmetic.
f(12) = 8 -10(12 -1) = -102
f(37) = 8 -10(37-1) = -352
