How is a tangent different from a chord? Explain.

2 answers:

8 0

A tangent intersects a circle at only one point, while a chord intersects the circle at two points. Also, a chord is contained within a circle, but a tangent is outside the circle, except for the point of tangency, which lies on the circle. Hope this helps :)

Hello!

1. A chord is a ray joining 2 points situated on a given curve.

2. A tangent is a ray that passes through only one point situated on the curve.

I Hope my answer has come to your Help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead! :)

Answer:

Step-by-step explanation:

B = (6,5) C = (6,9)

√(x2 - x1)² + (y2 - y1)²

√(6 - 6)² + (9 - 5)²

√(0)² + (4)²

√16

What is an equation of the line that passes through (-2,3) and is parallel to y=5x + 4.Give your answer in slope intercept form

9966 [12]

Answer:

y= 5x+13

Step-by-step explanation:

Slope- intercept form

y= mx +b, where m is the gradient and b is the y-intercept.

Parallel lines have the same gradient.

y= 5x +4

Gradient of given line= 5

Thus, gradient of line= 5

Subst. m=5 into the equation.

y= 5x +b

To find the value of b, substitute a coordinate

When x= -2, y=3,

3= 5(-2) +b

3= -10 +b

b= 3 +10 (+10 on both sides)

b= 13

Thus, the equation of the line is y= 5x +13.

A jogger goes half a mile north and then turns west. If the jogger finishes 1.3 miles away from the starting point, how far west

Ratling [72]

In order to solve this problem, you must draw a right triangle first to help you visualize the path of the jogger.
You are given 0.5 miles north (which will be the height of the right triangle), and 1.3 miles (which will be the hypotenuse of the triangle).
Using Pythagorean Theorem: a²+b²=c², we have:
0.5² + b² = 1.3²
b = 1.3²-0.5²
b = 1.2 miles
