Answer:

Step-by-step explanation:
we are given a function

we would like to simplify it for h(-1)
in order to do so
substitute the value of x

by order of PEMDAS
simplify square:

simplify multiplication:

simplify addition:

simplify subtraction:

reduce fraction:

63 miles in 270 minutes will mean that nolan rides his bike at a distance of 63/270 miles in one minute.
there are 60 minutes in an hour. So to find out the distance he covers in 1 hour, 63/270 × 60 will give you 14 miles.
Since the question is asking for the average speed, nolan rides his bike at 14 miles per hour i think.
Answer:
x positive, y negative
Step-by-step explanation:
-60 is the 4th quadrant of the unit circle ( negative angles go clockwise from 0), so the x value is positive and the y value is negative.
Answer: The shape is a rectangle. We know this because it has 4 corners and 4 sides. And it is a quadrilateral.
Step-by-step explanation:
for mean you add every number and divide it by the amount of numbers in the data set
for median you put the numbers in order and find the middle number, if there is no middle get the mean for the two middle numbers
range is basically the lowest and highest number
