Answer:
445.10 feet
Step-by-step explanation:
The relation between angle of depression and distance to the boat is ...
Tan = Opposite/Adjacent
tan(angle of depression) = (200 ft)/(distance to boat)
Then the distance to the boat is ...
distance to boat = (200 ft)/tan(angle of depression)
__
We want the change in distance between the two angles, so ...
change in distance = (200 ft)/tan(17°31') -(200 ft)/tan(46°41')
= (200 ft)(cot(17°31') -cot(46°41'))
change in distance ≈ 445.10 ft
Answer:
c.
Step-by-step explanation:
Let x be the number of adults in Tim's family. Then (17 - x) is the number of children in Tim's family.
We have $34x + $31.5(17 - x) = $558.
$34x + $31.5(17 - x) = $558
$34x + $535.5 - $31.5x = $558
$2.5x = $22.5
x = 9
Hence the answer is c.
Answer:
B
Step-by-step explanation:
The equation is y=mx+b
m=slope
b=y-intercept
So, F(X) = ( X - 5 ) ( Y - 2 )
When you wanna factor out some equation, try to spot things that are similar. Factoring is always a process of trial and error, but as you get more experience it will just get easier.
For example, in your question when you see y appear in many terms try to factor it out, and then produce what goes inside parenthesis.
