Use the interactive to make a vertical line with the equation of x = 3. The line x = 3 has slope.
Sliva [168]

Answer:

Slope of equation x = 3 is not defined.

Step-by-step explanation:

The graph for equation x = 3 is attached.

As clear from the graph, x=3, is a straight line parallel to y-axis.

Slope:

  • Since the given equation of line is parallel to the y-axis and parallel lines have same slope.
  • Parallel lines have the same slope and will never intersect. Parallel lines continue, literally, forever without touching

Thus, the given equation will have the same slope as the y-axis.

The slope of y-axis is not defined.

Hence, the slope of this line is not defined.

0.72 in scientific notation
boyakko [2]
Remember that scientific notation always contains a number between 0 and 10 that is multiplied by ten to some power. In this case, to get a number between 0 and 10 (7.2) we would move the decimal point once to the right. Since it is moving to ththe right, the exponent over the 10 will be negative, and it will be -1 because we moved the point once. So the answer is 7.2*10^-1

Hope this helps

A plane descends to sea level from 36 comma 400 feet after being airborne for 1 and one half hours. The entire flight time is 3
andrew-mc [135]

Answer:

350 feet per minute

Step-by-step explanation:

The amount of time it took the plane to descend is 3 hours 14 minutes minus 1 hour 30 minutes.

This means it took 104 minutes for the plane to descend 36,400 feet.

Dividing 36400 by 104, you get 350 which is the average rate of descent in feet per minute.
