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.

A right triangle is given with a missing value of t. It is stated that the triangle is an acute right triangle with angles 50∘ a

sergiy2304 [10]

Answer: t=20°

Step-by-step explanation:

1. By definition, the sum of the interior angles is 180 degrees.

2. Keeping the information above on mind, you can write the following expression:

$90+50+2t=180$

3. Now, you must solve for $t$ as following:

$140+2t=180\\2t=180-140\\2t=40\\t=\frac{40}{2}\\t=20$

4. Therefore, the value of $t$ is 20°
