Answer:

x = 17.5

Step-by-step explanation:

So its the same angle so it has to equal the same thing

5x+7 = 9x-63

+63 +63

5x+70=9x

-5x -5x

70 = 4x

/4 /4

17.5 = x

Find the area of the shape shown below.

hichkok12 [17]

Answer:

26.75 units ^2

Step-by-step explanation:

Since the shape is complex, divide it into 3 right angled triangles and one square. Find the area of these individual shapes first, then fin the sum of these area to calculate the ultimate area of e complex shape:

Triangle 1 = 1/2 x 2 x 5 = 5 units ^2

Triangle 2 = 1/2 x 2 x 2 = 2 units ^2

Triangle 3 = 1/2 x 3.5 x 9 = 15.75 units ^2

Square = 2 x 2 = 4 units squared.

Now add all these up 15.75 + 2 + 5 + 4 = 26.75 units squared.

The predicted cost c (in hundreds of thousands of dollars) for a company to remove p% of a chemical from its waste water is show

alukav5142 [94]

We presume your cost function is
c(p) = 124p/((10 +p)(100 -p))

This can be rewritten as
c(p) = (124/11)*(10/(100 -p) -1/(10 +p))

The average value of this function over the interval [50, 55] is given by the integral
$\frac{1}{55-50} \times \frac{-124}{11} \int\limits^{55}_{50} {(\frac{1}{x+10}+\frac{10}{x-100})} \, dx$
This evaluates to
(-124/55)*(ln(65/60)+10ln(45/50)) ≈ 2.19494

The average cost of removal of 50-55% of pollutants is about
$2.19 hundred thousand = $219,000
