Answer:
y=12x+10 or f(x)=12x+10
Step-by-step explanation:
If it costs $12 per month to rent as many movies as you want, then that can be represented as 12x
Since $10 is a flat fee and doesn't change, this gets added seperately to 12x
Thus, the final equation is y=12x+10 or f(x)=12x+10
Hope this helped!
Answer:
144 feet to nearest foot.
Step-by-step explanation:
Let the distance between Albert and the point on the ground that the balloon is directly above be x feet Then for Isaac the distance is 400 - x feet
So we have 2 right angled triangles and:
tan 62 = h/x
tan 48 = h / (400- x) where h is the height of the balloon.
From the first equation x = h / tan 62 so plugging this into the second one:
tan 48 = h / ( 400 - h/tan 62)
h = 400 tan 48 - h tan 48 tan 62
h + h tan 48 tan 62 = 400 tan 48
h ( 1 + tan48 tan62) = 400 tan48
h = 400 tan 48 / (1 + tan 48 tan 62)
= 143.8 feet.
