ASAP!! HELP!A) Describe The Relationship Among The Lengts Of The Segments Formed By The Secant (DB) And

Answers

Answer 1

Given the following parameters DB = 18 ft, AB = 3 ft, and CB = 10 ft. Therefore, The length of the CE is 4.6 ft.

What is Secant-secant rule?

The secant-secant rule states that if two secants are drawn from an external point to a circle, then the product of the measures of one secant's external part and that entire secant is equal to the product of the measures of the other secant's external part and that entire secant.

Mathematically:

(BA + AD)BA = (BE + EC)BE

Given the following parameters

DB = 18 ft, AB = 3 ft, and CB = 10 ft.

Substitute to check if we can find CE

(BA + AD)BA = (BE + CE)BE

(3+ 15) x 3 = (10 + CE ) x 10

18 x 3 = 100 + 10CE

54 = 100 + 10CE

CE = 4.6

Therefore, The length of the CE is 4.6 ft.

Always the easiest way to study these questions is to get a graph. The one below shows

Red: y = x^2

Blue: y= 3(x + 1)^2

You will notice that (x+1)^2 shifts the graph Left -- the opposite to what you might think.

The 3 is a little harder. It narrows the red mother graph. Which choice says that?

The choice is between b and d. Why. Because the blue graph is to the left of the red one.

Consider the equation y = 15 - 4x.
Which of the following is a graph of this equation?

Answers

The graph of the given linear equation is the one that you can see below.

How to get the graph of the linear equation?

To graph lines, we need to get two points on the line. To get the points, we can evaluate the line in two different values of x. Here I will use x = 1 and x = 0.

For x = 0 we have:

y = 15 - 4*0 = 15

So we have the point (0, 15).

For x = 1 we have the point:

y = 15 - 4*1 = 11

So we have the point (1, 11).

Now we need to graph these two points and connect them with a line, you will get the graph that you can see below.

The width of a rectangle is 32 inches shorter than twice its length. The area of the rectangle is 72 square inches. What is the length of the rectangle?

Answers

Answer:

18 inches

Step-by-step explanation:

Equation is (2x-32)(x)=72, where x represents length and (2x-32) represents the width. When you simplify the equation, it ends up as 2x^2-32x-72=0. After factoring, you get 2(x-18)(x+2). Since x cannot be negative, it would therefore be 18. If you plug it back into the equation, you can see that it is right :)

What is combination?

A combination is a way of selecting items from a collection where the order of selection does not matter. It is calculated by

[tex]^{n} C_{r} = \frac{n!}{(n-r)!}[/tex]

n is the total number of objects

r is the number of objects selected.

What is theoretical probability?

The theoretical probability is defined as the ratio of the number of favourable outcomes to the number of possible outcomes.

According to the question.

There are total 6 dishes.

Manger have to choose three dishes for monday.

Now the total number of combination of selecting 3 dishes from 6 dishes

[tex]=^{6} C_{3}[/tex]

Applesauce, broccoli, and cornapplesauce, brocolli, and dumplingsapplesauce, brocolli, and egg rollsapplesauce, brocolli, and french fries
