Answer:
4 1/2
Step-by-step explanation:
The point is marked at -4 1/2 on the number line. The distance from there to the origin is 4 1/2 units.
(Distances and lengths are always positive—as are values derived from them, such as perimeter or area.)
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 () after a certain amount of years (t) is given by the following formula:
Where:
- Initial amount of jobs in pipe fitting industry, measured in thousands.
- Average yearly rate, measured in thousands per year. (A decline is indicated by a negative sign)
If ,
and
, then:
The percent change in jobs from pipe fitting industry is calculated as follows:
The amount of jobs from fitting industry shall decline in 5.5 percent from 2015 to 2025.
Let y= mx-2 be the tangent line to y=x^2-4x+2 at x=a.
Then slope,
Hence the equation is y=(2a-4)x-2
Let's find y-coordinate at x=a using tangent line and curve.
Using tangent line y at x=a is (2a-4) a -2
Using given curve y-coordinate at x=a is
Let's equate these 2 y-coordinates,
a=2 or -2.
If a=2,
If a=-2,
Hence m values are 0 and -8.
