Brach and Larue is a home goods store chain, and it is about to introduce a new convection oven that’s expected to sell very wel

zvonat [6]

Answer:

$\$12,465$

Step-by-step explanation:

The functions for cost and revenue are given below:

$Projected \:Revenue,R(x)= -13.85x^2 + 1660x\\$Projected Cost, C(x)=55400 -279x\\Projected Profit = Revenue-Cost=R(x)-C(x)\\=-13.85x^2 + 1660x-(55400 -279x)\\=-13.85x^2 + 1660x-55400 +279x\\P(x)=-13.85x^2 + 1939x-55400$

The profit will be maximized at its line of symmetry, $x=-\dfrac{b}{2a}$

From P(x), a=-13.85, b=1939

Line of symmetry,

$x=-\dfrac{b}{2a}=-\dfrac{1939}{2(-13.85)}=70$

The maximum profit that can be made will occur when x=70

$P(x)=-13.85x^2 + 1939x-55400\\P(70)=-13.85(70)^2 + 1939(70)-55400\\=\$12,465$

The maximum profit that can be made form the sales of the oven is $12,465.

HELP PLZ DUR 11;59 plz help me

Norma-Jean [14]

Answer:

Base = 10 cm

Height = 60 cm

Step-by-step explanation:

The formula for the area of a triangle is $area=\frac{1}{2} *b*h$ , where b is the length of the base of the triangle, and h is the length of the height of the triangle.

We know the area is 300, and since the height of the triangle is 6 times its base, we know that $h=6*b$ . We can plug in these values into our formula for the area of a triangle, which gives us the following equation to solve:

$300=\frac{1}{2} *b*(6*b)$

$3b^2=300$

$b=\sqrt{100} =10$

The base of the triangle is 10 centimeters.

Now that we know the base of the triangle, we can plug its value in to the original formula to solve for the height of the triangle, which gives us the following equation:

$300=\frac{1}{2} *10*h$

$5h=300$

$h=60$

The height of the triangle is 60 centimeters.
