find the measure of the central angle of a circle if it's minor are length is 14π and the radius is 18 inches
MrMuchimi

Step-by-step explanation:

Length of arc of a circle is given as:

l =  \frac{ \theta}{360 \degree}  \times 2\pi \: r \\  \\  \therefore \: 14\pi = \frac{ \theta}{360 \degree}  \times 2\pi \:  \times 18 \\  \\ \therefore \:\theta =  \frac{14\pi \times \: 360 \degree }{2\pi \:  \times 18} \\  \\ \therefore \:\theta =  \frac{7 \times \: 360 \degree }{18}  \\  \\ \therefore \:\theta =  7 \times \: 20 \degree \\  \\  \huge \red{ \boxed{\therefore \:\theta =  140 \degree}}

Thus, the measure of central angle is 140°.

Find the equation of the line that is perpendicular to y=5 through the point (-4,-6)
Nikolay [14]

Answer:

x=-4

Step-by-step explanation:

we know that

The given equation y=5 is a horizontal line (is parallel to the x-axis)

The slope of the given line is equal to zero

A perpendicular line to the given line is a vertical line (parallel to the y-axis)

so

The equation of a vertical line is equal to the x-coordinate of the point that passes through it

The point that passes through it is (-4,-6)

therefore

The equation of the perpendicular line is

x=-4

A phenomenon is observed many, many times under identical conditions. The proportion of times a particular event A occurs is rec
Sever21 [200]

Answer:

A. The probability of event A

Step-by-step explanation:

The proportion of times a particular event A occurs is known as the probability of event A because the probability is the measure of uncertainty and by definition probability is calculated as

P(x)=X/n

where

P(x) is the probability of occurring of random variable X

X=number of favorable outcomes

and

n= total number of outcomes.

Thus, the proportion of times a particular event A occurs is known as the probability of event A.
