A retailer who sells fashion boots estimates that by selling them for x dollars each, he will be able to sell 70−x boots each we

Marat540 [252]

Answer: $35 is the selling price and $1225 is the maximum revenue.

Step-by-step explanation:

Since we have given that

$R(x)=-x^2+70x$

We need to find the maximum revenue.

So, We will first derivative it w.r.t. x.

So, it becomes,

$R'(x)=-2x+70$

Now, we will find critical points.

So, R'(x) = 0

So, it becomes,

$-2x+70=0\\\\-2x=-70\\\\x=\dfrac{70}{2}=35$

Now, to check whether it yields maximum revenue or not.

So, second derivative w.r.t. x, we get that

R''(x) = -2<0

So, At $35, it yields maximum revenue.

Amount of maximum revenue would be

$R(35)=-(35)^2+70\times 35=-1225+2450=\$1225$

Hence, $35 is the selling price and $1225 is the maximum revenue.

Five ninths times the difference of f and 32

Viktor [21]

If we put that into an equation, we get
(5/9)(f/32)
because "five ninths" is a fraction, "times" is multiplication (which can be represented by parenthesis), "the difference" is division, and "the difference of f and 32" is a fraction.

A parabola can be represented by the equation x2 = 2y. What are the coordinates of the focus and the equation of the directrix?

Vera_Pavlovna [14]

Answer:

the coordinate of the focus is: (0, 1/2)

the equation of the directrix is: y=-1/2

Step-by-step explanation: The standard equation for a parabola that opens upward- parallel to the y-axis, is: x2=4ay. Meaning, a = distance from the vertex to focus and the vertex is at origin: (0,0).

4a is equal to 2

a is equal to 2/4

a is equal to 1/2 or 0.5
