For this question, we have to use the Pythagorean theory since we're dealing with a right triangle.
a² + b² = c²
We're given the value of the hypotenuse and a leg, therefore we're looking for the value of the other leg.
Now let's plug in the given data into our equation.
2² + b² = 5²
4 + b² = 25
b² = 25 - 4
b² = 21
√b² = √21 = b
The correct answer is B) √21
a) The linear function is:
b) The estimate for the number of people employed in 2012 is of 569.2.
-----------------------------
A linear function has the following format:
In which
- m is the slope, that is, how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
-----------------------------
Item a:
- During the first year of observation, the number of people, in thousands of dollars, was of 373. Thus, the y-intercept is
- In 10 years, it changed from 373 to 591, thus, the slope is:
The function is:
-----------------------------
Item b:
2012 is 9 years after 2003, thus, this is
The estimate for the number of people employed in 2012 is of 569.2.
