On a map, 1 in. represents 20 mi. Two cities are 31 in. apart on the map.
How far apart are the actual cities?
O 23ļmi
O 60gm
O zom
O 75 m

620 mi.

Step-by-step explanation:

If 1 inch represents 20 miles, we have a ratio of 1:20.

Since the cities are 31 inches apart on the map, multiply 31 by 20:

The cities are 620 miles apart.

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

f(x) is   are being squared

g(x) is   increasing by 2

h(x) is adding .25 each time

k(x) is taking the square root

f(x) and k(x) are exponential functions
