Answer:

  d.  76(cos(3π/16) +i·sin(3π/16))

Step-by-step explanation:

To form the product of 38cis(π/8) and 2cis(π/16), multiply the magnitudes and add the angles:

  38cis(π/8) × 2cis(π/16) = (38×2)cis(π/8 +π/16) = 76cis(3π/16)

___

The actual distance between two cities is 1250 mi. the shortest distance between the two cities on a map is 10 in. what is the s
Varvara68 [4.7K]
So the scale is usually ine inch of the map to actual distance right?we
So we need to calculate how much one inch is.
So we are told 10 inches is 1250 miles right?
So for one inch we need to divide the number of inches for the equivalent distance.
In this case it is 10 and 1250 miles.
So dividing 1250 by 10 gives you 125 right?
That means for every one inch on the map it is 125 miles right.
This can be written like 1:125.
This is how they write scales in the map.
It means for one unit in the map it is 125 units in real life

Uwu this isnt a test but its practiceee
igor_vitrenko [27]

<u>Answer</u>: B, (-3/2, -1)


<u>Step-by-step explanation:</u>

When you use the midpoint formula, (x1+x2/2 , y1+y2/2) you end up taking one away from -4, and dividing it by 2 (-3/2), and when you add 2 to -4, you get -2, divided by 2, is -1.
