Answer:
yes, no, no
Step-by-step explanation:
The triangle will be a right triangle if the sum of the squares of the two short sides, less the square of the long side, is zero. (This is what the Pythagorean theorem tells you.) The angle where the radius meets the circle must be a right angle if the line is to be a tangent.
__
a) 3^2 +4^2 -5^2 = 9 + 16 -25 = 0 . . . . AB is a tangent
__
b) 9^2 +15^2 -18^2 = 81 +225 -324 = -18 . . . . AB is not a tangent
__
c) 10^2 +48^2 -52^2 = 100 +2304 -2704 = -300 . . . . AB is not a tangent
I think is d that what i tink
Answer:
y = 5.5x - 17
Step-by-step explanation:
(4,5)(2,-6)
- M = ∆y/∆x
- -6-5/2-4
- -11/-2 this is the gradient
- chose any of the point then introduce another point
- (4,5) (x,y) the gradient is -11/-2
- M =∆y/∆x
- y-5/x-4 = -11/-2
- -2(y-5) = -11 ( x -4)
- -2Y + 10 = -11x + 44
- -2Y = -11x + 44 -10
- -2Y = -11x + 34
- divide the while equation by -2
- y = 5.5x + - 17
- y= 5.5x - 17
Answer:
54π
Step-by-step explanation:
To find the volume of the cylinder, you will be using V=π(r^2)h
r = radius = 3
h = height = 6
V = π(3^2)(6) = 54π
The bracket means to multiply.
