Determine if line AB is tangent to the circle.

Mathematics
1 answer:
Charra [1.4K]3 years ago
6 0

Answer:

7) No

8) Yes

Step-by-step explanation:

Tangent lines are perpendicular to the radius lines at the point of intersection.  So we just need to check if these are right triangles.

7) c² = a² + b²

20² = 12² + 14²

400 = 340

No

8) c² = a² + b²

13² = 7.8² + 10.4²

169 = 169

Yes

The table below represents a linear function f(x) and the equation represents a function g(x):
Aneli [31]
Slope of f(x)


Slope of g(x)


PART A)
The slopes of f(x) and g(x) are the same.

PART B)
The equation for line f(x)
y = 4x + b
-1 = 4(0) + b
-1 = b

y = 4x - 1

The function G(x) has a bigger y-intercept. The y-intercept of g(x) is 3, while the y-intercept of f(x) is -1.
