The distance between points
and
can be calculated using formula

1.

2.

3.

Then

Answer: correct choice is C.
If we let x as the number of years of service in the company and f(x) as the increase in the wage, the step wise function that describes the scenario is
f(x) = { 0.5, x < 3
{ 1.0, 3 ≤ x < 6
{ 1.5, 6 ≤ x < 9
{ 2.0, 9 ≤ x < 12
The point (2, 12) represents the wage increase of x < 12
we are given
quadratic equation as

now, we can find b and c from

we can see that coefficient of x^2 is 1
so, we will have to make coefficient x^2 as 1
so, we divide both sides by 3



now, we can simplify it

now, we can compare it with

we get


so, we get order pair as
..............Answer
Answer:
8.65 miles
Step-by-step explanation:
The total of his short runs are 9.35 so you need to find out how many miles he has left till he reaches 18 miles.
The equation you can use is 9.35 + x = 18 x will equal the number of miles for the long run.
9.35 + x = 18
to isolate x you will subtract 9.35 from both sides.
you will get:
x = 8.65
8.65 miles
Answer:
The scale factor is 1.2.
Step-by-step explanation:
18/15 = 1.2
30/25 = 1.2
24/20 = 1.2
Hope that helps!
