Answer:
the answer is 40 hope this helps you
Working backwards, we first subtract 1. That is 228. Next you divide 228 by 4, which is how many parts they have in all. That is 57. 57 times 3 is how much ben has. Your answer is 171.
Answer:
6926 pairs in 2016.
Step-by-step explanation:
The number of pairs in t years after 2010 is modeled by the following function:
In which P(0) is the number of pairs in 2010 and r is the growth rate, as a decimal.
608 pairs in 2010
This means that 
So
4617 pairs five year later.
So P(5) = 4617. We use this to find 1 + r.
![1 +r = \sqrt[5]{\frac{4617}{608}}](https://tex.z-dn.net/?f=1%20%2Br%20%3D%20%5Csqrt%5B5%5D%7B%5Cfrac%7B4617%7D%7B608%7D%7D)
So
How many pairs in 2016?
2016 is 2016 - 2010 = 6 years after 2010. So this is P(6).
6926 pairs in 2016.
Hints:
use the calculator to check if any of the options are correct. Try x=pi/6 (or 30 degrees).
Odd functions satisfy the property
f(x)=-f(-x)
For this reason, odd functions are symmetrical about the origin.
Examples of odd functions: sin(x), x^3, x+3x^5, tan(x), sin(x)*cos(x), x*sin(x)
(use your calculator to check that the above are true).
Even functions satisfy the property
f(x)=f(-x)
Even functions are symmetrical about the y-axis.
Examples: x^2, cos(x), x^4+2, |x|, sin^2(x), x^2*cos(x)
There are functions that are neither odd nor even,
examples:
x^2+4x+3, sin(x)+cos(x)
