The pipe fitting industry had 546.5 thousand jobs in 2015 and is expected to decline at an average rate of 3 thousand jobs per y
lesya692 [45]

Answer:

The amount of jobs from fitting industry shall decline in 5.5 percent from 2015 to 2025.

Step-by-step explanation:

Due to the assumption of a yearly average rate, a linear function model shall be used. The expected amount of jobs (n) after a certain amount of years (t) is given by the following formula:

n = n_{o} + \frac{\Delta n}{\Delta t}\cdot t

Where:

n_{o} - Initial amount of jobs in pipe fitting industry, measured in thousands.

\frac{\Delta n}{\Delta t} - Average yearly rate, measured in thousands per year. (A decline is indicated by a negative sign)

If n_{o} = 546.5, t = 2025-2015 = 10\,years and \frac{\Delta n}{\Delta t} = -3\,\frac{1}{years}, then:

n = 546.5+\left(-3\,\frac{1}{year}\right)\cdot (10\,years)

n = 516.5

The percent change in jobs from pipe fitting industry is calculated as follows:

\%n = \left(1-\frac{n}{n_{o}}\right)\times 100\,\%

\% n = \left(1-\frac{516.5}{546.5}\right)\times 100\,\%

\%n = 5.5\,\%

The amount of jobs from fitting industry shall decline in 5.5 percent from 2015 to 2025.

What needs to be corrected in this construction of a line parallel to [\overleftrightarrow?]AB passing through C?
JulsSmile [24]

The option that needs to be corrected in this making of a that is line parallel to AB via C is known to be the second arc should be centered at C.

<h3>Why should the second arc be centered at C.</h3>

The second arc should be centered at C because as it crosses via Line C, it is seen that it was not touching or intersecting AB and so one can say that it is a  parallel to it.

Looking at the other lines, you will see that they are all touching AB and are not running parallel to it.

Therefore, The option that needs to be corrected in this making of a that is line parallel to AB via C is known to be the second arc should be centered at C.

See full question below

What needs to be corrected in this construction of a line parallel to AB passing through C?

A) The first arc should pass through C.

B) The first arc should pass centered at C.

C) The second arc should be centered at C.

D) The second arc should cross the first arc.

E) The second arc should be centered at F

How to find intersections of two overlapping circles with complicated equations?
Lorico [155]
Option 1: Graph both equations to see where they intersect.  If they do not intersect at lattice points, then use the substitution method.

Option 2: Use substitution method of system of equations
Equation of a circle: (x-h)² + (y-k)² = r²
Choose one of the equations and solve for one of the variables
(I am choosing to solve for y)::
(y-k)² = r² - (x-h)²
|y - k| = √(r² - (x-h)²)
y - k = +/- √(r² - (x-h)²)
     y = k +/- √(r² - (x-h)²)

Now, substitute k +/- √(r² - (x-h)²) for y into the other equation to solve for x.
Substitute those x values into y = k +/- √(r² - (x-h)²) to solve for y.

Hope this makes sense!
