Paul is making a map for geography. in order to draw the map, he must create a scale converting the measured inches on the map to actual miles.

length in inches 1-1/4 1-1/2 1-3/4 2-1/4 2-1/2 2-3/4

length in miles 25 30 35 45 50 55

use the table above to identify the scale he used for his map.

a. 1 in = 10 miles

b. 1 in = 5 miles

c. 1 in = 20 miles

d. 1 in = 15 miles

  C. 1 in = 20 miles

Step-by-step explanation:

The lengths are proportional, so you can form the ratio of any pair and reduce it to a ratio to 1 inch:

  (25 miles)/(1.25 in) = (25/1.25) miles/in = 20 miles/in

Paul's scale is 1 in ⇒ 20 miles.

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i

option: d is correct
