Answer:
The Jonathon and Raymond need to sell 6000 sales to earn the same amount each month.
Step-by-step explanation:
Given data
Let no. of sales = x
Jonathon earning = $ 1500 + 
Raymond earning = $ 1200 + 
Given that the earnings of Jonathon & Raymond are same.
1500 + = 1200 +
300 = 
x = 6000 sales
Therefore the Jonathon and Raymond need to sell 6000 sales to earn the same amount each month.
There are several ways to do this by converting<span> the percentage to a fraction </span><span>by placing thee expression </span><span>over </span><span /><span><span><span><span><span><span><span>100</span></span></span></span></span></span><span>100</span></span><span>. Percentage means out of 100 and it will look like this 170/100.
Reduced the expression. 17/10
or in whole number it is 1 17/10</span><span />
Ok, so remember that the derivitive of the position function is the velocty function and the derivitive of the velocity function is the accceleration function
x(t) is the positon function
so just take the derivitive of 3t/π +cos(t) twice
first derivitive is 3/π-sin(t)
2nd derivitive is -cos(t)
a(t)=-cos(t)
on the interval [π/2,5π/2) where does -cos(t)=1? or where does cos(t)=-1?
at t=π
so now plug that in for t in the position function to find the position at time t=π
x(π)=3(π)/π+cos(π)
x(π)=3-1
x(π)=2
so the position is 2
ok, that graph is the first derivitive of f(x)
the function f(x) is increaseing when the slope is positive
it is concave up when the 2nd derivitive of f(x) is positive
we are given f'(x), the derivitive of f(x)
we want to find where it is increasing AND where it is concave down
it is increasing when the derivitive is positive, so just find where the graph is positive (that's about from -2 to 4)
it is concave down when the second derivitive (aka derivitive of the first derivitive aka slope of the first derivitive) is negative
where is the slope negative?
from about x=0 to x=2
and that's in our range of being increasing
so the interval is (0,2)
