$4.5 since 1.26/7 is .14 and need 25 so it’s 4.5
The cost function is given as,
Obtain the first derivative as,
Obtain the critical points by equating the first derivative to zero,
Thus, the Cost function has an extrema at point 290.
Apply the second derivative test,
Since the second derivative is positive, the function attains minimum value at the critical point.
Therefore, it is concluded that the cost is minimum at 290.
Substitute the value in the function to obtain the minimum cost,
Thus, the minimum unit cost is $10749 which corresponds to 290 units of cars.
Answer:
Step-by-step explanation:
<u>First, Let's solve for x in -2x+2y=-4:</u>
<u>Subtract 2y from both sides:</u>
<u>Divide both sides by -2:</u>
<u>Now, we'll substitute x=y+2 to 3x+3y=-18:</u>
→ let x=2+y
<u>Simplify:</u>
<u>Now, let's solve for y in 6+6y=-18</u>
<u>Subtract 6 from both sides:</u>
<u>Divide both sides by 6:</u>
<u>Now, substitute y=-4 into x=2+y:</u>
→ let y = -4
Therefore, x=-2 and y=-4.

Answer:
Step-by-step explanation:
I'm not sure if I understood what the problem is asking for and if the numbers behind 3 are answer choices but the answer would be 21.
3's times table:
Since 3 times 7 equals 21 the following equations involving division with the numbers 3, 7, and 21 would be:
