I do not understand this problem. Can I please get some help?

Explanation:

CD and BC are radii of the same circle. We are shown BC = 9, so CD is also 9

Through the segment addition postulate, we know that,

AC = AD + DC

AC = 6 + 9

AC = 15

The angle ABC is 90 degrees as this is a tangent point at the circle.

Triangle ABC is a right triangle. The leg AB is unknown, which we'll call x. The other leg is BC = 9. The hypotenuse is AC = 15

Use the pythagorean theorem to solve for x

a^2+b^2 = c^2

x^2+9^2 = 15^2

x^2+81 = 225

x^2 = 225-81 ... subtracting 81 from both sides

x^2 = 144

x = sqrt(144)  ... applying square root to both sides

x = 12

AB = 12

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
