Company earns S dollars by selling y items per week. According to the equation S(y)=−2y^2+60y+10, how many items does company ne

sp2606 [1]

Answer:

$Max = 15$

Step-by-step explanation:

Given

$s(y) = -2y^2 + 60y + 10$

Required

Determine number of items that gives maximum earnings;

The general form of a quadratic equation is:

$s(y) = ay^2 + by + c$

And the maximum is calculated as:

$Max = \frac{-b}{2a}$ If a<0

Comparing $s(y) = ay^2 + by + c$ to $s(y) = -2y^2 + 60y + 10$

We have that:

$a = -2$ $b = 60$ $c = 10$

Substitute these values to

$Max = \frac{-b}{2a}$

$Max = \frac{-60}{2 * -2}$

$Max = \frac{-60}{-4}$

$Max = 15$

<em>The number of item that maximizes the function is when y = 15</em>

Give me the answer for 2 1/5 times 4

Korvikt [17]

2 1/5* 4
= (11/5) * 4
= 44/5
= (40+ 4)/5
= 40/5+ 4/5
= 8+ 4/5
= 8 4/5

The final answer is 8 4/5~

Find the value or values of the Y in the quadratic equation y squared + 4 y + 4 equals 7

QveST [7]

Y² + 4y + 4 = 7
   - 7 - 7
y² + 4y - 3 = 0
   y = -(4) ± √((4)² - 4(1)(-3))
   2(1)
   y = -4 ± √(16 + 12)
   2
   y = -4 ± √(28)
      2
   y = -4 ± 2√(7)
      2
   y = -2 ± √(7)
   y = -2 + √(7) U y = -2 - √(7)
