A line which passes through at least two points of a curve

Mathematics
1 answer:
UNO [17]3 years ago
3 0

Answer:

A line which passes through at least two points of a curve is called secant line.

Step-by-step explanation:

Consider the provided statement.

A secant, is a line that passes through two curve points.

It connects two points in the Cartesian plane on a curve where the curve can be describe by a function.

A secant line commonly refers to a line that intersects a circle at exactly two points.

Remember: The secant line is almost the same as a tangent line when two points are closed together.

Hence, A line which passes through at least two points of a curve is called secant line.

Write the equation of the circle with the given graph.
lara [203]

By identifying the radius and the center, we concluded that the equation is something like:

(x - 2)^2 + (y - 1.5)^2 = 1.8^2

<h3></h3><h3>How to write the equation of the circle?</h3>

For a circle centered on the point (a, b) with a radius R, the equation is:

(x - a)^2 + (y - b)^2 = R^2

So first we need to identify the center, we can see that it is: (2, 1.5)

And the radius is the distance between the center and the edge.

R  = 1.8 (measured with a ruler, respecting the notation of the graph).

Then the equation of the circle is something like:

(x - 2)^2 + (y - 1.5)^2 = 1.8^2

Use the Euclidean Algorithm to find the greatest common divisor of the polynomials f(x) = x^3 + 3x^2 + 6x + 1 and g(x) = 5x^4 +
fomenos

Answer:

3x+1.

Step-by-step explanation:

First we divide g(x)/f(x) (the process is in the first image):

5x-15 in Z7[x] is 5x-1 and 17x^2+86x+16 is r(x)= 3x^2+2x+2 in Z7[x]. So

g(x)/f(x) = (5x-1)(x^3+3x^2+6x+1)+3x^2+2x+2

Now gcd(g,f) = gcm(f,r).

f(x)/r(x) = 5x(3x^2+2x+2) + 3x+1

Then, gcd(f,r) = gcd(r,3x+1).

r/(3x+1) = (x+5)(3x+1) +4

Then, gcd(r, 3x+1) = gcd(3x+1,4) = 3x+1.

So, gcd(f,g) = 3x+1.

16. You found a shortcut to school that saves 5 minutes off of taking the freeway. About 1 in every 10 trips
kykrilka [37]

Answer:

  it saves 2.5 minutes

Step-by-step explanation:

The expected value of a random variable is the sum of products of possibilities and the probability of each.

Here, you have a probability of 0.9 of saving 5 minutes, and a probability of 0.1 of adding 20 minutes.

__

The expected value of the shortcut is ...

  0.9(-5) +0.1(20) = -4.5 +2.0 = -2.5

The shortcut is expected to save 2.5 minutes on average.

_____

<em>Additional comment</em>

The probability of 0.9 comes from the 9 of 10 trips that result in a time saving.
