Answer:

Step-by-step explanation:
Please see the attached picture.

☆In the gradient formula,
(x1, y1) is the first coordinate and (x2, y2) is the second coordinate.
300. if you sold a third. then 2/3 would be left. you can then infer each is 300
Dixon will earn $2,205.00 in two years. Every year he earns 5% of the original amount each year. Multiply 2000 by 0.05 (which is 5% in decimal form). This equals to 100. Add this to 2000 to get 2100. Multiply that number by 0.05 also to get 105. Add that to 2100 and get $2205. (Hopefully this is correct, i learned this a while ago and this is what I thought of on the top if my head).
AO = 21
BC = 14
OC = radius of the circle = AO = 21
∴ OB = OC + CB = 21 + 14 = 35
<span>Line AB is tangent to circle O at A</span>
∴ AB is perpendicular to AO
∴ Δ OAB is a right triangle at A
Applying Pythagorean theorem
∴ OB² = AO² + AB²
∴ AB² = OB² - AO² = 35² - 21² = 1225 - 441 = 784
∴ AB = √784 = 28
