What is the maximum or minimum of the quadratic function y = 16x^2 +40x +25

1 answer:

6 0

Y = 16x^2+ 40x + 25

The sign before the 16 is positive, so it's a parabola with a minimum. The x coordinate of the minimum is: 
x=-b/2a=-40/32=5/4=-1.25 

If you fill that in, you get y=0 

so the coordinates are (1.25, 0)

xxMikexx [17]

Given:

Kim picked 250 pounds of pears yesterday and 287 pounds of pears today.

To find:

The percentage increase of amount of pears picked by Kim.

Solution:

We know that,

$\%\text{ increase}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100$

$\%\text{ increase}=\dfrac{287-250}{250}\times 100$

$\%\text{ increase}=\dfrac{37}{25}\times 10$

$\%\text{ increase}=\dfrac{370}{25}$

$\%\text{ increase}=14.8$

Therefore, the percentage increase of amount of pears picked by Kim is 14.8%.
