Answer:
A=907.92
Step-by-step explanation:
A=πr^2
A=π(17)^2
A=approximately 907.92
Let x represent the number of A printers
<span>Let y represent the number of B printers </span>
<span>Minimize cost = 86x + 130y </span>
<span>subject to </span>
<span>Total printers equn: x + y ≥ 100 </span>
<span>Total profit equn: 45x + 35y ≥ 3850 </span>
<span>x ≥ 0, y ≥ 0 </span>
<span>x and y must be whole numbers. </span>
<span>The vertices of the feasible region are: (0, 100), (100, 0) and (35, 65) </span>
<span>If x = 35 and y = 65 the cost is 11460 and profit is 3850 </span>
<span>if x = 100 and y = 0 the cost is 8600 and profit is 4500 </span>
<span>If x = 0 and y = 100 the cost is 13000 and profit is 3500 </span>
<span>The best result is x = 100 and y = 0</span>
Answer:
double, real root x = -4
Step-by-step explanation:
Please use " ^ " to indicate exponentation: 2х^2 + 8х = х^2 - 16.
Combine like terms:
х^2 + 8х = - 16.
Re-write in the standard form for a quadratic:
х^2 + 8х + 16 = 0
Recognize that this is the square of the binomial x + 4:
х^2 + 8х + 16 = 0 => (x + 4)^2 = 0
Solving this last result for x yields the double, real root x = -4.
Answer:
2/8 Green
Step-by-step explanation:
Since the green has two sections on the spinner it has two chances out of 8 to be landed on.
Well first if he buys 24 a month that equation is 24n n = months and if he already has 523 the explicit rule is an = 24 | 24 | 24 |
