Let C(x) be the cost to produce x batches of​ widgets, and let R(x) be the revenue in thousands of dollars. R(x) = − x² + 6x​, C
Musya8 [376]

Answer:

Step-by-step explanation:

Let C(x) be the cost to produce x batches of​ widgets, and let R(x) be the revenue in thousands of dollars.

R(x) = -x^2 + 6x,\\ C(x) = x + 4.

Profit function = Revenue  - cost

So we get profit function by subtracting C(x) from R(x) using algebraic method of subtraction.

Profit function of x

= Pr(x) = R(x) -C(x)\\= -x^2+6x-x-4\\=-x^2+5x-4

A construction company wants to build an auditorium on a trapezium shaped plot measuring 410m2. One of the parallel sides of the
Assoli18 [71]

Answer:

other parallel side is 23m

Step-by-step explanation:

Let's assume other parallel sides as 'x'

One of the parallel sides of the trapezium plot measure 18m

so, y=18

distance between the two parallel sides measure 20m

so, h=20

now, we can use area of trapezium formula

A=\frac{1}{2}\times h \times (x+y)

now, we can plug values

A=\frac{1}{2}\times 20 \times (x+18)

we can set A=410

and then we can solve for x

410=\frac{1}{2}\times 20 \times (x+18)

10\left(x+18\right)=410

x+18=41

x=23
