In 1985 the population density of a country was 55 people per square mile, and in 2000 it was 79 people per square mile. use a linear function to estimate when the population density reached 90 people per square mile.

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

not sure but it may be b, as i said i'm not sure.

i believe the answers 600m

the answer is 3/2 and for decimal: 1.5

hope i
