6m^2 - 7m - 20
I would show work but I just used a calculator instead.
Anyway, I hope this helps :)
Answer:
36
Step-by-step explanation:
2ft x 60 SECONDS = 120 ft
120ft x 60 minutes = 7200ft per hour
The volume of the sphere is given as:
π = 3.14
r = 4.5 inches
Using the values, we get:
Thus, the volume of sphere rounded of to nearest tenth is 381.5 cubic inches
Answer:
[-6, 8]
Step-by-step explanation:
Domain: set of all possible <u>input</u> values (x-values)
Range: set of all possible <u>output</u> values (y-values)
The <u>closed circles</u> on the <u>endpoints</u> of the curve mean that those points are <u>included</u> in the interval.
From inspection of the graph, the smallest y-value is -6 and greatest y-value is 8.
To express this in <u>interval notation</u> write the beginning and ending numbers of the interval inside <u>square brackets</u> as the end values are <u>included</u>.
(If the circles were open, and therefore the end values should not be included, use curved brackets).
Therefore the range of the given graph is: [-6, 8]
