Answer:
yes
Step-by-step explanation:
just sub in the 4 for the w and see if the equation can be solved. if it can, then w=4 is a solution.
since 4 IS less than 11 5, w=4 can be a solution.
Brainliest please!!! Have a good day!!!!
Answer:
if the input has more than one arrow coming from it that whole table is not a function but if it only has one its a function
Step-by-step explanation:
u can only have one arrow from input for it to work as a function but if theres mutiple arrows from the output its still a function
If u were to graph that function used u would have to solve it first
Answer:
no this isnt a function
Step-by-step explanation:
a equation that's function has to have numbers and can only include the
letter X as the unknown variable
but this problem has a ^ sign
so it's not function
The cost formula is as follows:
c = 2πrh *
0.02 + 2πr^2 * 0.05 <span>
c = 0.04 πrh + 0.10 πr^2
</span>
<span>The formula for volume in terms of height is:
h = V/(πr^2)
h = 300/(πr^2)
</span>
<span>Substituting this h into the cost formula:
c = 0.04 πr[300/(πr^2)] + 0.10 πr^2
c = 12/r + 0.10 πr^2
c' = - 12/r^2 + 0.20 πr
</span>
<span>Equating to zero to get minima:
- 12/r^2 + 0.20 πr = 0
r^3 = 12/(0.20 π)
r = 2.673 cm
h = 300/(π * 2.673^2)
h = 13.365 cm
<span>So the radius must be 2.673 cm and height 13.365 cm</span></span>
