The rule that relates between the speed, distance and time is as follows:
speed = distance / time
We are given that:
distance = 100 meters
time = 20 seconds
Substitute with the givens in the above equation to get the expression for the speed as follows:
speed = distance / time
speed = 100 / 20 meters / second
Hope this helps :)
Answer:
It is 8.72 if it needs to be rounded up. If not, it is 8.71779788708
Step-by-step explanation:
Y - y1 = m(x - x1)
slope(m) = 13
(-2,5)...x1 = -2 and y1 = 5
sub...pay attention to ur signs
y - 5 = 13(x - (-2)...not done yet
y - 5 = 13(x + 2) <== point slope form
It is easiest to simply just substitute any of the choices into the original equation and see which one satisfies the equation.
Given the equation: 3 * |5 + x| = 12
Using choice A. x = 7
3 <span>* |5 + 7| = 12
</span>36 =/= 12
Using choice B. x = 1
3 <span>* |5 + 1| = 12
</span>18 =/= 12
Using choice C. x = -9
3 <span>* |5 + -9| = 12
</span>12 = 12
Therefore, the correct answer is C. -9
1) 61
2)7
3) 20,333.33333333333
