Answer:
91.204 cubic feet
Step-by-step explanation:
We are given that
Height of great pyramid, h=480feet
Side of square base, a=755 feet
Height of Danny's pyramid, h'=480/100 feet
Side of square base of Danny's pyramid, a'=755/100 feet
We have to find the volume of Danny's pyramid if the volume of Danny's pyramid is 1/100 the size of great pyramid.
We know that
Volume of square base pyramid, V=
Where a= Side of base
h=Height of pyramid
Using the formula
Volume of Danny's pyramid=
Volume of Danny's pyramid=91.204 cubic feet
Answer:
domain: all real numbers
range: y ≥ -5
Step-by-step explanation:
The domain of any polynomial function is "all real numbers."
This polynomial is of even degree and has a positive leading coefficient. It will have a minimum value, but no maximum. We can get an idea of the minimum value by looking at the vertex form.
f(x) = x^4 -2x^2 -4
f(x) = (x^4 -2x^2 +1) -5 = (x^2 -1)^2 -5
The squared term will have a minimum value of 0, so the minimum of f(x) is -5.
The range is all real numbers greater than or equal to -5.
Plug in x as 30 and now u have y = 14 - 15 which is -1
Answer:
75
Step-by-step explanation:
In running 0.6 miles, you have gone from 300 remaining to 255 remaining, so have burned ...
300 -255 = 45 . . . . . calories
The rate in calories per mile is ...
(45 cal)/(0.6 mi) = 75 cal/mi
At the rate of the first 0.6 miles, you will burn 75 calories running 1 mile.
