Y=-1/4(x- - 2)^2+ 4
You can see it take shape by drawing it out. Then shift x left by 2 (-2) and up 4 (+4) . A trick for the slope is that by looking at .75 you know it has to be some fraction with a even denominator.
Use these facts to count the approximate area of the unshaded region:
1. (from the table);
2. ;
3. ;
4. (from the table);
5. ;
6. .
Then the approximate area of the unshaded region is .
Answer: correct choice is C.
Answer:
For this case we can make the following rule of three:
4 cc ----------------> 25
x --------------------> 140
Clearing the value of x we have:
x = (140/25) * (4)
x = 22.4 cc
Answer:
the standard dose for a 140 pound woman is:
x = 22.4 cc
