the angle θ is 7.2 degrees, and the circle arc s is 800 km. knowing that there are 360 degrees in a full circle what is the circ
kumpel [21]

The earth is 40000 kilometers around. There is no need to round off because the circumference already contains significant figures.

How do I calculate a circle's circumference?

A circle's diameter is multiplied by to determine its circumference (pi). You can also determine the circumference by multiplying 2radius by pi (=3.14).

Given: theta angle (central) = 7.2°; arc length S = 800 km

This indicates that an 800 km long arc is extending a circle with a 7.2° center angle ( earth in this case).

By definition, "An arc's length is a portion of a circle's diameter."

Therefore, we must first establish what percentage of the circle the specified arc length represents.

360° is a complete circle.

Thus, the fraction equals 7.2°/360°, or 1/50.

As a result, the stated arc length (800km) with a 7.2° central angle is 1/50th of the entire circle.

Thus, the whole circumference is 800 x 50, or 40000 km.

Alternately, you can calculate circumference using the formula below:

360° center angle x arc length as the circumference (theta)

Values substituted: circumference 800 = 360° 7.2°

circumference = 360°, 800°, and 7.2°, or 40000 kilometers

Therefore, the earth is 40000 kilometers around. There is no need to round off because the circumference already contains significant figures.

Use a graphing calculator to find the value of the correlation coefficient r to determine if there is a strong correlation among
OlgaM077 [116]

The value for r = - 0.8535 ,  there is strong correlation between the variables.

<h3>What is a correlation coefficient  ?</h3>

Correlation coefficient describes the relationship between the two variables in the data .

The data given is

(1, 7), (2, 5), (3, -1), (4, 3), (5, -5)

Assuming Linear Regression ,

The data is plotted on the graphing calculator

The value for r = - 0.8535

as the value is in the range of - .85 to -1 , therefore there is strong correlation between the variables.

64,223=_____=641.23<br>​
FrozenT [24]

Answer: Check

12^10 × 12^(-2) = 12^(10 - 2) = 12^8

________________________________

Second option : ---

3^2 × 4^6 = 3^2 × 4^2 × 4^4 = 12^2 × 4^4

________________________________

Third option : ---

(12^8)^0 = 12^(8 × 0) = 12^0 = 1

________________________________

4th option : Check

12^10 / 12^2 = 12^10 × 12^(-2) = 12^(10 - 2)

= 12^8

________________________________

5th option : Check

2^8 × 6^8 = ( 2 × 6 )^8 = 12^8
