What is the distance between the points (−9,−2) and (50,54)?

1 answer:

3 0

This question can be found using the distance formula. This formula can be written as d=sqrt((x2-x1)2+(y2-y1)2). I’d advise looking up the formula, as mobile wont let me format the exponents. Plug in your values, and you should get d=sqrt(3481+3136). Simplify this, and you will get d=sqrt(6617).

Please show me how you got the answer thanks.

Answer:

B. (3,0)(0 ,-6)

Step-by-step explanation:

What is intercept.?

Intercept are those points where a given line cuts across a given axis.

So for the equation y = 2x - 6

To find the intercept we will bear in mind that we are looking for two points.

The point where the line cuts both the x axis and the y axis .

And to determine that, we will set both x and y to be equal to zero and then solve for both.

So let x = 0

Y = 2x -6

Y = 2(0) -6

Y = -6

One point = (0 ,-6)

Let y = 0

Y = 2x -6

0 = 2x -6

6 = 2x

X = 3

One point = (3,0)

The two points are

(3,0)(0 ,-6)

Estimate the area of a circle with a radius of 16 meters. Use 22/7 or pi

Dmitrij [34]

1. Area of a circle is pi(R)^2 , where R is the radius. So we can substitute:

22/7(16^2) = about 805 meters squared.

2. Let's find the area of the rectangle first.

A=LW
A= 18(10)

A= 180 cm squared.

Now the semi-Circle:

The radius of the circle is 9 (because 18/2 is 9). Now we plug in to the area formula:

22/7(9^2) = about 254 cm squared. But because that is the area of the whole circle, and we only need half of the circle, we divide that value by 2 to get:

127 cm squared for the semi-circle.

Now we add up the rectangle and semi-circle's areas:

180 + 127 = 307 cm squared as your answer.

I hope this Helps!
