Answer:

Step-by-step explanation:
CD is perpendicular to AB
If any radius or diameter is perpendicular to any chord of a circle, then it bisects that chord.
Mean, AB= BE = 12
So, AB = 2(BE)
2(12)= 24
so your answer will be 24

hope it helps..
have a great day!!
Answer:
The equation for total cost function is
C(x)=100+270x
Step-by-step explanation:
Variable cost per per board =total cost per day-fixed cost per day/daily output
total cost per day is $5,500
fixed cost per day is $100
20 boards are produced per day
variable cost per board=($5,500-$100)/20=$270 per day
Total cost C(x)=fixed cost per day+ variable per board*number of daily output
Since daily output is represented also by x ,total cost function is given thus:
C(x)=100+270x
Answer:
63pi
Step-by-step explanation:
the formula for the volume of a cylinder is pi r^2 h
r=radius
h=height
3=r
7=h
pi((3)^2)7
63pi units^3
Hope that helps :)
4.
The equation we have is:

To solve for "a", we want to isolate it in one side.
For this. we can start by multiplying each side by 5. This will make the denominator to cancel out:

Now, we can divide both sides by 8, which will cancel the coefficient 8 multiplying "a":

And that is the answer to 4.
Step-by-step explanation:
5p + 6p -10 = -29 - 8p
11p - 10 = -29 - 8p
+10 +10 +8p
+8p = -19
19p=-19
p=-1
