Vertex form for a quadratic function:

y = a(x - h)^2 + k

where the vertex is at: (h, k)

You should be able to "read" these functions...

Think !

[y = (x - 5)^2 - 4]

6n+n^2

I wrote 6n + n (square)

Thats all, I think the equation is incomplete...

6. Below are the home states of 17 college professors.

Ohio Georgia New Jersey Georgia Nebraska
Michigan Ohio Pennsylvania South Carolina New Jersey
New Jersey South Carolina Wisconsin Michigan Pennsylvania
Ohio Wisconsin

i. Make a frequency table using these 8 states:
Georgia
Michigan
Nebraska
New Jersey
Ohio
Pennsylvania
South Carolina
Wisconsin

ii. What is (are) the mode(s)?
iii. Does it make sense to talk about the average for this data? Why or why not?
iv. Using your frequency table draw a pie chart to display the distribution of home states by filling in the following table:
Home State Frequency Percentage of total Measure of Central Angle (in degrees)
Georgia
Michigan
Nebraska
New Jersey
Ohio
Pennsylvania
South Carolina
Wisconsin

Submit your solutionshere so I can see how it's done, Thank you!

How many hours will it take for the population to grow to 1,000 bacteria? Round your answer to the nearest integer. Do not include units in your answer.
B(t) = 50 *e0.5tAnswer Question

by taylor-a... Member since:April 27, 2009Total points:969 (Level 2)If you have a graphing calculator, plug the equation into the y=.
Expand your window so that you can see the population (probably the y axis) untill you can see 1000. Some cushion would be helpful so make the window a little bigger.
Plug 1000 into the y= also and find where the line intersects your function.
(If you didn't know, the e is above the divide symbol on the calculator.)
I hope this helps.
