How do you determine whether a relationship represented as as graph is linear or nonlinear

1 answer:

3 0

It is linear if it is a straight line (i.e. you could line the graph up with a ruler), and nonlinear if it isn’t a straight line

What is the distance between (-2 1/2,-3) and (1,-3

satela [25.4K]

Answer:

$3\frac{1}{2}\ units$

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have

$(-2\frac{1}{2},-3)\ and\ (1,-3)$

Convert mixed number to an improper fraction

$2\frac{1}{2}=\frac{2*2+1}{2}=\frac{5}{2}$

we have

$(-\frac{5}{2},-3)\ and\ (1,-3)$

substitute the values in the formula

$d=\sqrt{(-3+3)^{2}+(1+\frac{5}{2})^{2}}$

$d=\sqrt{(0)^{2}+(\frac{7}{2})^{2}}$

$d=\frac{7}{2}\ units$

Convert to mixed number

$\frac{7}{2}\ units=\frac{6}{2}+\frac{1}{2}=3\frac{1}{2}\ units$

Jen ran for 10 minutes with the speed of 6 mph and then walked for 30 minutes at a speed of 3 miles per hour. What is the total

MaRussiya [10]

Answer:

The total distance covered by Jen was 4 miles.

Step-by-step explanation:

The formula for the average speed is shown below:

speed = distance / time

In this question we need to find the distance covered, therefore we will adjust the formula as shown below:

distance = time*speed

We will need to convert the time from minutes to hours, we do that by dividing by 60.

The total distance covered by Jen is the sum of the distances on each stage of his course, therefore:

total distance = distance 1 + distance 2

Applying the correct formula:

total distance = (time1 * speed1) + (time2 * speed2)

total distance = [(10/60)*6] + [(30/60)*3]

total distance = [60/60] + [90/60] = 1 + 3 = 4 miles

THe total distance covered by Jen was 4 miles.
