Answer:
4% Hope this helped.
Step-by-step explanation:
The formula is: final value minus starting value divided by the starting value then times 100
THIS FORMULA ONLY APPLIES TO PERCENT INCREASE
<u>Final Value−Starting Value</u>
Starting Value x100
Plug numbers in
2600-2500/2500 x 100
100/2500=0.04
0.04x100
=4%

Answer:
The function f(x) = 1/5x2 – 5x + 12 is a quadratic function, because the higher exponent is 2.
The correct statements are:
- The value of f(-10) = 82
- The graph of the function is a parabola
- The graph contains the point (20,-8)
Step-by-step explanation:
- The value of f(-10) = 1/5(-10)2 – 5(-10) + 12 = 1/5(100)+50+12 = 82 (<em>True</em> s<em>tatement</em>).
- The graph of the function is a parabola, as all the quadratic functions. (<em>True</em> s<em>tatement).</em>
- The graph of the function opens down: The parabola opens up or down depending on the "a". It is the important part of the function that determines whether it opens up or down, the parabola will open up when "a" is greater than zero.
When "a" is smaller than zero the parabola will open down. In our example a = 1/5 (greater than zero, so the parabola opens up). <em>(False Statement)</em>
- The graph contains the point (20,-8). For f(20) = 1/5(20)2 - 5(20) +12 = 1/5(400) - 100 + 12 = 80 - 100 + 12 = -8 <em>(True Statement).</em>
- The graph contains the point (0,0). For f(0) = 1/5(0)2 - 5(0) + 12 = 12, the correct point is (0,12) <em>(False Statement)</em>.
