For this problem, we are given a quadratic equation that models the total amount spent on clothing and footwear in the years 2000-2009. We need to use the model to determine the maximum amount spent during the period.
The equation is shown below:
Since the leading term is negative, the vertex of this function will represent an absolute maximum value. Therefore we can determine the vertex to answer the problem, the vertex's coordinates are given below:
Then we have:
In the year 2008, 384 billion was spent on clothing and footwear.
Answer:
1, 3, 6, 10, 15, 21, 28, 36, 45, 55, 66, 78, 91
Step-by-step explanation:
Answer: Chris reached Boston at 10:24 a.m.
Explanation:
Since we have given that
Speed at which Chris ran from Newton to Boston = 15 km/h
Speed at which Goffy ran from Newton to Boston = 12 km/h
Time at which both started = 10:00 a.m.
Time at which Goffy reached Boston = 10:30 a.m.
That means Goffy takes half an hour to reach Boston,
so, Distance between Newton and Boston is given by
So, Time taken by Chris to ran from Newton and Boston is given by
So, Chris reached Boston at 10:24 a.m.

<u>Explanation</u></h3>
- Solve the equation for x-term.
We move 39 to multiply 24/13.
Substitute x = 72 in the equation.
The equation is true for x = 72.

================================================
Explanation:
The general equation they give is c = rg
Solving for r leads to . We divided both sides by g to get this.
Now pick any point on the diagonal line. I'll pick (3,10)
The graph shows the horizontal axis is g and the vertical axis is c. The point (3,10) means g = 3 and c = 10 pair up together.
Making r to be,
and the equation in the form c = rg would be
