Find the distance between the pair of points.

Answer:

Distance is \sqrt{290} units

Step-by-step explanation:

Use the distance formula which is d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} where d is the distance between points (x_1,y_1) and (x_2,y_2)

We are given that (x_1,y_1) is (-6,-23) and (x_2,y_2) is (-23,-24), therefore the distance between the two points is:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

d=\sqrt{(-23-(-6))^2+(-24-(-23))^2}

d=\sqrt{(-23+6))^2+(-24+23))^2}

d=\sqrt{(-17)^2+(-1)^2}

d=\sqrt{289+1}

d=\sqrt{290}

Therefore, the distance between (-6,-23) and (-23,-24) is \sqrt{290} units.

Practice with Conversions
mylen [45]

Answer:

1) Newbury Park → The distance is accurate.

2) Thousand Oaks → The distance is not accurate.

3) Los Angeles → The distance is not accurate.

Step-by-step explanation:

It is important to remember that:

1\ mile=1.609\ kilometers

Knowing this, you can make the corresponding conversions:

1) Newbury Park

10 miles to kilometers:

(10\ mi)(\frac{1.609\ km}{1\ mi})=16.0\ km

The distance shown in that California highway sign is accurate.

2) Thousand Oaks

13 miles to kilometers:

(13\ mi)(\frac{1.609\ km}{1\ mi})=20.9\ km

The distance shown in that California highway sign is not accurate.

3) Los Angeles

55 miles to kilometers:

(55\ mi)(\frac{1.609\ km}{1\ mi})=88.4\ km

The distance shown in that California highway sign is not accurate.

Sum of two digit number is9.When we interchange the digits it is found that the resulting new number becomes twice the other num
ruslelena [56]

Answer:

4 and 5

Step-by-step explanation:

Let the numbers be x and y

If their sum is 9, hence;

x + y = 9 ....1

When reversed

10y+x = 2(10x+y)

10y+x = 20x + 2y

10y - 2y = 20x - x

8y = 19x

y = 10x/8 ...2

Substitute equation 2 into 1;

From 1;

x+y = 9

x +(10x/8) = 9

18x/8 = 9

18x = 72

x = 72/18

x = 4

Since x+y =9

y = 9-x

y =9-4

y = 5

Hence the numbers are 4 and 5

Please I need help! I will mark you as brainliest!
Nadusha1986 [10]

Answer:

Step-by-step explanation:

SIDE OF THE SQUARE = 6 cm = DIAMETER OF THE CIRCLE.

AREA OF THE CIRCLE = (Pi/4)*6^2 = [(22/7)/4]*36 = 22*9/7 = 28.2857 sqcm

or

First, find the side length of the square. (Find the square root of 36 cm^2, to get 6 cm as the side length of the square).

Second, find the radius of the circle inside the square. The side length of the square is the diameter of the circle. Radius is half of the diameter. So, half of 6 cm is 3 cm; this is the radius of the circle.

Third, find the area of the circle by using the formula, A = pi x radius x radius

so, Area = 3.14 x 3 cm x 3 cm

by calculation we get the area of the circle is 28.26 cm^2

Where pi is a constant of 22/7 or 3.14
