BB_1 is the angle bisector of triangle ABC, and I is its incenter. The perpendicular bisector of segment AC intersects the circumcircle of triangle AIC at D and E. Point F is on the segment B_1C such that AB_1=CF. Prove that the four points B, D, E and F are concyclic.

correct

step-by-step explanation:

283 square feet

step-by-step explanation:

good luck

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
