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>

What is the slope intercept form of the equation of the line that passes through the points (9,5) and (4,1)

aivan3 [116]

Answer:

y = 4/5 x - 2 1/5

Step-by-step explanation:

1. Find the slope:

1 - 5/ 4 - 9 = 4/5 = m

2. Find b by plugging in the m and one of the points given into y = mx + b

1 = 4/5 ( 4) + b

1 = 16/5 + b

-2 1/5 = b

3. Write the equation using the m and the b you just found

y = 4/5 x - 2 1/5

Which equation represents a direct variation

Mazyrski [523]

Direct variation is is when the x and y a direct relation

without constants added or subtracted

With being times by each other

so the only one that meets the definite is the first one

y = 0.5x means y is equal to half of x. So you know that every y is directly related to half of x
