In the circle, measure of Arc BC = 62°. The diagram isn't drawn to scale. what is the measure of Arc BCP?

Answers

Answer:

Option D. ∠BCP = 31°

Step-by-step explanation:

As we know by the theorem tangent and chords, an angle formed by a chord and a tangent that intersect on a circle is half the measure of the intercepted arc.

Theorem clearly reveals ∠BCP = (mBP)/(2)

Since arc BC = 62°

So ∠BCP = (62)/(2)=31

Option D. ∠ BCP = 31° is the answer.
PQ is the tangent, therefore you can use a theorem: The arc measure is double the amount of the angle the tangent makes.

So: 62/2=31

The formula of a distance between two points:

d=√((x_2-x_1)^2+(y_2-y_1)^2)

We have two points A(-5, 2) and B(-5, 8). Substitute:

d=√((8-2)^2+(-5-(-5))^2)=√(6^2+0^2)=√(6^2)=6

d is a diameter of a circle because d = 2r = 2(3).

The center of a circle is in midpoint of AB.

The formula of a midpoint:

M\left((x_1+x_2)/(2),\ (y_1+y_2)/(2)\right)

Substitute:

(-5+(-5))/(2)=(-10)/(2)=-5\n\n(2+8)/(2)=(10)/(2)=5

Answer: (-5, 5).

Since this figure is a parallelogram then the opposite are equal to each other.

AD = BC

Plug in

2x + 2 = 3x - 1

-2x -2x

-------------------------

2 = x - 1

+1 +1

-------------------------

3 = x

-------------------------

x = 3

Step-by-step explanation:

2x + 2 = 3x - 1

-2x -2x

2 = x - 1

+1 +1

x = 3

Can someone please help me with this, marking brainliest and giving 15 points!The distance traveled of a coin dropped from a tall building is modeled by the equation d(t) = 4.9t2 where d equals the distance traveled at time t seconds and t equals the time in seconds. What does the average rate of change of d(t) from t = 3 to t = 6 represent? (2 points)

The coin falls down with an average speed of 132.3 meters per second from 3 seconds to 6 seconds.

The coin falls down with an average speed of 44.1 meters per second from 3 seconds to 6 seconds.

The coin travels an average distance of 132.3 meters from 3 seconds to 6 seconds.

The coin travels an average distance of 44.1 meters from 3 seconds to 6 seconds.

Answers

change in distance = 176.4 - 44.1 = 132.3
change in time = 6 - 3 = 3

The object travels 132.3 meters in 3 seconds

the speed is the ratio of the two values

speed = distance/time
speed = 132.3/3
speed = 44.1 meters per second

This is the average speed of the object from t = 3 to t = 6 seconds. This is equivalent to the slope of the straight line through the two points.

The answer is The coin falls down with an average speed of 44.1 meters per second from 3 seconds to 6 seconds.`
