Answer:
=16.492
Step-by-step explanation:
3√17 is a surd that can be broken into 3 × √17
√17 = 4.123 ( to 4 S.F )
3 × 4.123 = 16.492
The decimal form is an estimation as it has many digits that can only be rounded off or truncated.
Positive= growth, and negitive = reduction of that.
example, -5= a reduction of 5 meters

A)The y-intercept is 50 because when X=0, y=50. This shows that the car was moving at 50 mph as an initial speed.
B) in two hours (from 1 to 3) the speed increased by 4 miles per 2hours. (from 52 to 56). 4/2 = 2 mph, which is the average rate of change. This represents the amount of speed increased each hour.
C) y=2x+50, and y=60 in this case, so 60=2x+50
60=2x+50
-50 -50
-----------------
10=2x
5=x, so the domain is X<=5 (less than or equal to 5)
