X=46.2
_____________________________
99.2 + 62 = 161.2
180 -161.2 = 19.8
19.8 + 112 = 131.8
180 - 131.8 = 48.2
48.2 - 2 = 46.2
D is the correct answer. Through careful planning unnecessary expenses can be rid of
Answer:
11.400 dollars... is the answer
Answer:
western beach: y = -2x + 100
dunes beach : y = 5x + 20
set the equations equal to each other
-2x + 100 = 5x + 20
100 - 20 = 7x
80 = 7x
80/7 = x
x ~ 11.43 years
Step-by-step explanation:
I got
t = 6.614
-16t^2 +1700 = 1000
-16t^2 = -700
t^2 = 43.75
You need to divide by 16 first, before you take the square root.
Domain = what values of time would be used here?
t > 0, since negative time not reasonable. And you probably need to find when the ball hits the ground, since after that time, the ball would be underground.
So the a reasonable domain is from 0 to 10.3078
Range: what values of height seem reasonable?
h > 0, because negative height would mean that the ball was underground.
And ... since the ball was "dropped" from a height of 1700 (vs being "thrown up" from a height) the maximum height would be 1700.
So ... a reasonable range would be from 0 to 1700.
Hope this helps... :)
