Answer:
15
Step-by-step explanation:
Let f(x) be the function
A linear approximation of f is the Taylor polynomial of degree one:
Taking a = 16, and given that
we get
so
<em>Since 16 > 14, we can deduce that this is an overestimate.
</em>
Let t be the time passed in years and y be the value of baseball card.
You know that
- when x=0, then y=2;
- when x=5, then y=25;
- when x=10, y=8.
The equation in standard form is
Substitute given data into the equation:

Solve the system of equations:


Then the parabola equation is

Answer:
28
Step-by-step explanation:
Area of a rectangle = width times length therefore the equation is 7 times 4 = 28.
Step One
Figure out the actual change.
Change = 2.78 - 2.45
Change = 0.33
Step 2
Find the % change
% Change = 0.33/2.45 * 100 = 13.5%
