How far will a train travel in 5 hours if it travels at 80 miles per hour?
Lunna [17]

Answer:

  C.  400 miles

Step-by-step explanation:

In each hour, it travels 80 miles. (That is the meaning of "80 miles per hour.") So you can add up the distances over a period of 5 hours:

  80 miles + 80 miles + 80 miles + 80 miles + 80 miles

After the first sum (80+80=160), you can see what the correct answer will be. Continuing, you find the sum to be ...

  = 400 miles

___

Multiplication was invented to make repeated addition easier.

  5 × 80 miles = 400 miles

_____

Strictly speaking, you are multiplying numbers with units here:

  (5 h) × (80 mi/h) = 400 mi·h/h = 400 mi . . . . . . the units h/h cancel

Print out the graph paper from the "Let's Review" section. Sketch the graph of y = 2tanx for -pi/2 ≤ x ≤ pi/2
snow_lady [41]

Answer:

<h2>The graph is attached below.</h2><h2>Same asymptote as similarity and the slopes are different.</h2>

Step-by-step explanation:

We need to find the graph of y = 2 \times tanx.......... \frac{-\pi }{2} \leq  x \leq \frac{\pi }{2}

When x = 0; y = 0\\x = \frac{\pi }{4} ; y = 2\\x = - \frac{\pi }{4} ; y = -2

and \lim_{x \to \frac{\pi }{2} } y =  \infty\\ \lim_{x \to - \frac{\pi }{2} } y = - \infty

The asymptotes are x = \frac{\pi }{2} \\ x = - \frac{\pi }{2}

If we compare the graphs of y = 2 \times tanx.....(1)\\y = tanx......(2)

then the similarities are, they have same asymptote.

Difference between them is the rate of change that is the slope of the equations.
