an angle of 50°
sum triangle is 180
180- (90 + 50 )
= 180 - 140

Assume that the total revenue received from the sale of x items is given​ by, ​R(x)equals34 ln (4 x plus 5 )​, while the total c
katen-ka-za [31]

Answer:

63 units

Step-by-step explanation:

The profit function P(x) is given by the revenue function minus the cost function:

P(x) = R(x) - C(x)\\P(x) = 34ln(x+5)-\frac{x}{2}

The number of units sold 'x' for which the derivate of the profit function is zero, is the number of units that maximizes profit:

P(x) = 34ln(x+5)-\frac{x}{2}\\P'(x) =0= \frac{34}{x+5}-\frac{1}{2}\\x+5=68\\x=63\ units

The number of units that should be manufactured so that​ profit is maximum is 63 units.

Line m passes through the points (2, -7) and (4, -9) line m is parallel to which line
zhannawk [14.2K]

Answer:

The Answer is: The slope is -1, so any line with the same slope is parallel.

Step-by-step explanation:

Given points (2, -7) and (4, -9) find the slope, m:

m = y - y1 / (x - x1)

m = -7 - (-9)/(2 - 4)

m = -7 + 9/-2

m = 2/-2

m = -1

A parallel line is any line with the same slope which is -1.

Hope this helps! Have an Awesome day!!  :-)
