Answer:
-3/2
Step-by-step explanation:
This equation is written in point-slope form (y-y1)=m(x-x2). Since the variable m always represents slope in basic mathematics then the slope is 5.
The length of AB is 9.
Solution:
Given data:
Radius OC = 8
Tangent AC = 15
The angle between the tangent and radius is always right angle.
∠C = 90°.
Hence OCA is a right triangle.
Using Pythagoras theorem,
<em>In a right triangle square of the hypotenuse is equal to the sum of the squares of the other two sides.</em>




Taking square root on both sides of the equation, we get
OA = 17
OB is the radius of the circle.
⇒ OB = 8
AB = OA – OB
= 17 – 8
= 9
AB = 9
Hence the length of AB is 9.
52 cents would be the answer.
Hope this helped. Would you like me to explain how I got it?
Answer:
A
Step-by-step explanation:
Taking the square root of both sides, you get

which simplifies to

The square root of 180 is approximately 13.42 and since it is the plus or minus square root, the answer is A, -13.42, 13.42.
