Answer:

1. (10,-4)

2. 12

3. 108

Step-by-step explanation:

First find the cordinate by seing were the point lands on the graph

sense it is +10 right the x = 10, and it is 4 below the origin making it a negitive 4, so u get (10,-4)

The graph is measured 2 units per box and sence the sides are parallel to the axies you can count each square by 2, giving you the measuers of 12 units.

Now finally, The area of a triangle is A=1/2bh, we arlready have our base, and we just found our hight, so now we just have to plug it in.

A= 1/2 (12) (18)

12*18 = 216

A= 1/2 (216)

A= 108

And we are done!

A company producing steel construction bars uses the function C(x) = 0.02x2-3.4x+150 to model the unit cost in dollars for produ

lubasha [3.4K]

To get minimized number of x steel bars, we differentiate the equation and then equate to zero:
d/dx (C(x) = 0.02x² – 3.4x + 150)
C'(x) = 0.02(2)x – 3.4 = 0

Solving for x
0.04x – 3.4 = 0
x = 85 steel bars

For minimum cost,
C(x = 85) = 0.02(85)² – 3.4(85) + 150 = 5.5 dollars

Answer:

width = 126 ft

Step-by-step explanation:

I'm going to assume that I am solving for width.

Area = width x length

84 = 2/3 x width

Now divide 84 by 2/3 to get the width (when you divide by a fraction, you actually multiply by its reciprocal, so it is 84 times 3/2)

84 x 3/2 = width
