Find the length of an arc of 40° in a circle with an 8 inch radius.
lora16 [44]
The length of an arc is the fraction of its circumference based on the given intercepted angle. This is given by the equation,
                                  L (arc) = (Angle / 360) x 2πr
Substituting the known values,
                                  L (arc) = (40 / 360) x 2π(8 inch)  = 16π/9 inch
Thus, the length of the arc is approximately equal to 5.585 inches.

Wewaii [24]

Answer:

Step-by-step explanation:

probability of choosing a boy = 12 / 28 = 3 / 7

in % = 3 / 7 x 100 = 42,86%

probability of choosing an a student = (4 + 10) / 28 = 14 / 28 = 1 / 2

in % = 1 / 2 x 100 = 50%

Determine the slope of the line that has the following coordinates: (5, 9)(11, - 3)
AlladinOne [14]

Answer:

x_1 = 5, x_2 =11, y_1 =9, y_2 = -3

The slope can be founded with this formula:

m =\frac{y_2 -y_1}{x_2 -x_1}

And replacing we got:

m =\frac{-3 -9}{11-5}= -2

And the best answer for this case would be :

m=-2

Step-by-step explanation:

For this case we have the following two points given:

x_1 = 5, x_2 =11, y_1 =9, y_2 = -3

The slope can be founded with this formula:

m =\frac{y_2 -y_1}{x_2 -x_1}

And replacing we got:

m =\frac{-3 -9}{11-5}= -2

And the best answer for this case would be :

m=-2

What is the value of g(0)<br> -2<br> -1<br> 3<br> 6
Tanzania [10]

Answer:

Step-by-step explanation:

An x value of 0 can only be plugged into the equation that has a domain that includes 0. The first function's domain is between -2 and -4, so 0 is not included in that domain. In the third function, the domain is between 1 and 3, so 0 is not included in that domain, either. The middle function's domain does include 0 (0 falls between -2 and 1) so we can only evaluate this function at an x value of 0.

g(0) = -0 - 1 so

g(0) = -1
