A pilot can travel for 140 miles with the wind in the same amount of time as 360 miles against the wind. Find the speed of the w
quester [9]

Answer:

  -88 mph

Step-by-step explanation:

We can use the relation ...

  time = distance/speed

to compare the times in the two directions.

  \dfrac{140}{200+w}=\dfrac{360}{200-w}\\\\140(200-w)=360(200+w)\\\\200(140-360)=w(360+140)\\\\w=\dfrac{200(-220)}{500}=-88 \quad\text{miles per hour}

The wind speed is -88 miles per hour.

_____

The problem statement tells us the travel is slower <em>with</em> the wind than <em>against</em> the wind. Hence "with the wind" must be subtracting from the net speed. That is, the wind speed is negative.

Answer:

When y = |x + h|, the graph is shifted (or translated) <u>to the left.</u>

When y = |x - h|, the graph is shifted (or translated) <u>to the right.</u>

Step-by-step explanation:

Part A:

The parent function of vertex graphs are y = |x|, and any transformations done to y = |x| are shown in this format (also known as vertex form): y = a|x - h| + k

(h , k) is the vertex of the graph.

So, for the first part, what y = |x + h| is saying is y = |x -  (-h)|.

The -h is substituted for h, and negatives cancel out, resulting in x + h.

This translates to the left of the graph.

Part B:

For the second part, y = |x - h| looks just like the normal vertex form. In this one, we are just plugging in a positive value for h.

This translates to the right of the graph.

Euler's formula is given by:
 C + V = A + 2
 Where,
 C: number of faces
 V: number of vertices
 A: number of edges.
 Clearing A we have:
 A = C + V-2
 Substituting values:
 A = 21 + 14-2
 A = 33
 Answer:
 
the missing number is:
 
C.33
