The population density of a certain region is 60 people per square kilometer if the region covers 23 square kilometers what is the population of the region

Population = 1.380

Step-by-step explanation:

 Step 1 :

Population density is  defined as the measure of average the  population of people per unit of area( per square mile). And is calculated as

Population density =

Number of People / Land Area in Square Km.

Step 2

given  Population density = 60 people per square kilomete

Land Area= 23 square kilometer

Population =Population density x Land Area in Square Km

=  60 people per square kilometer x 23 square kilometer

=1,380.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
