A = 200 cm = 2 m 
b = 90 cm = 0,9 m
d = ? (m)

Pythagorean theorem
a^2+b^2=d^2
 {d=\sqrt{a^2+b^2}=\sqrt{2^2+(0.9)^2}=\sqrt{4+0.81}=\sqrt{4.81}=2.19317 ...(m) \ \approx 219, 32 \ (cm)}

You are skateboarding at a pace of 30 meters every 5 seconds. your friend is in-line skating at a pace of 9 meters every 2 secon
AnnyKZ [126]

In order to graph the relationship, we will need to write the expression as the equation of a straight line as shown:

d = mt + b

d is the distance covered

t is the time taken

m is the speed

If you are skateboarding at a pace of 30 meters every 5 seconds. your friend is in-line skating at a pace of 9 meters every 2 seconds, this can be written as (5, 30) and (2, 9)

Get the slope of the line:

m = (9-30)/(2-5)

m = -21/-3

m = 7

Substitute m = 7 and the coordinate (2, 9) into the equation y = mt + b

9 = 7(2) + b

9 = 14 + b

b = -5

The required equation to plot will be expressed as y = 7t - 5

Plot the required graph
