D'(p) = -8p + 160
<span>-8p + 160 = 0 </span>
<span>-8p = -160 </span>
<span>p = 20 </span>
<span>~~~ </span>
<span>B) Number of drills sold when p = 20 is </span>
<span>D(20) = [ -4(20)^2 + 160(20) - 270 ] = 1,130 drills </span>
I think this is right, i tried.
It’s -7/2
If it’s wrong I’ll correct it in the comments
Answers are:
16.
-1 - (-4) = 3
17.
-1-1/3 - (-4) = 2-2/3
18.
2 - (-1) = 3
19.
3-1/2 - (-1) = 4-1/2
20.
3-1/2 - 2 .= 1-1/2
21.
3-1/2 - (-1-1/3) = 4-5/6
Step by step: I took one point and subtracted the second point to get the length of each segment. You could also look at the ruler and count from one point to the other.
Remember when you subtract a negative, the two negatives become a positive
Answer:
X = 10 Y = 14
Step-by-step explanation:
Okay, so. If you divide the Y and X for example 2.8 divided by 2 is 1.4 5.6 divided by 4 is 1.4. So like it says it is proportional. So, when you get down to the eight. You can see they are adding the X by 2 so the X is 2. The Y would be 2.8. So, you would add 2.8 into 11.2. That would be 14.
Hope this helps!
