Answer:
See attached image for the graph of the function
Step-by-step explanation:
Notice that this is the product of a power function (
) times the trigonometric and periodic function cos(x). So the zeros (crossings of the x axis will be driven by the values at which they independently give zero. That is the roots of the power function (only x=0) and the many roots of the cos function: 
, and their nagetiva values.
Notice that the blue curve in the graph represents the original function f(x), with its appropriate zeros (crossings of the x-axis), while the orange trace is that of "-f(x)". Of course for both the zeroes will be the same, while the rest of the curves will be the reflection over the x-axis since one is the negative of the other.
Answer:
2/3*22/7*r^3=231.6
2/3*22/7=2.0952
2.0952*r^3=231.6
r^3=231.6/2.0952
r^3=
Step-by-step explanation:
2/3*22/7*r^3=231.6
2.0952r^3=231.6
r^3=110.5384
cuberoot 110.5384
=4.7992
Answer:
The answer is 82.20.
Step-by-step explanation:
First you 68.50 x .20. Which equals 13.7. Then you add that to the total of the dinner. That is 68.50 + 13.7 = 82.20

numbers are closee under addition.
Explanation: that means that the addtion of two real numbers is always a real number.
Integers are not closed under division.
Explanaton: that means that when you dived an integer number by another integer number the result may be a non integer number.
Irrational numbers are not closed under multiplication.
Explanation: that means that the multiplication of two irrational numbers may result in a rational number.

are closed under subtraction.
Explanation: that means that the result of the subtraction of rational numbers is always a rational number.
