Suppose that the percent p (as a decimal) of people who could correctly identify two of eight defendants in a drug case t days after their trial began is given by:

p(t) = t^2+ 8.1t+ 0.06

a. Find the number of days before the percent is maximized.
b. Find the maximum percent.

a) 4 days, b) Maximized percent = 16.46.

Step-by-step explanation:

Since we have given that

We need to find the maximum percent and number of days before the percent is maximized.

So, first we derivative the above p(t), we get that

Now, we will find the critical points :

So, we will check at t = -4.05, whether it gives maximum percent or not.

So, it becomes,

So, a) there would be 4 days before the percent is maximized.

b) maximum percent would be

Hence, a) 4 days, b) Maximized percent = 16.46.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.
