Answer:

4*3 - 3*3;

Joe read 3 more books than Craig

Step-by-step explanation:

Given

Craig:

3 books weekly for 3 weeks

Joe:

4 books weekly for 4 weeks

Required

How many more books did Joe read.

First, we need to determine number of books Craig reads

If in a week, Craig reads 3 books

Then in 3 weeks, Craig reads 3 * 3 books

Next, we need to determine number of books Joe reads

If in a week, Joe reads 3 books

Then in 4 weeks, Joe reads 4 * 3 books

Next, we determine the difference;

$Difference = 4 * 3 - 3 * 3$

$Difference = 12 - 9$

$Difference = 3$

Hence, Joe reads 3 more books

Option D answers the question.

leonid [27]

The coordinates of the focus are (h,k+1/4a)(h,k+1/4a)

y=1/38*x^2
here h=0,k=0 ,a=1/38

so if we put values to find focus
focus(0,0+1/4*1/38)=(0,9.5)
