Find the measure of the angle shown by the arrow(in radians)
soldi70 [24.7K]

Answer:

-7π/3 or -420 degrees

Step-by-step explanation:

So we know that the arrow has made one full rotation and that it is moving in a clockwise direction. So already we have -2π degrees.

The arrow stops at π/6 before the next π/2 rotation. Therefore we find the difference between the two.

π/2 - π/6

3π/6 - π/6 = 2π/6

π/3

Since this is still clockwise, we make this negative. So the measure of the angle shown by the arrow is -2π - π/3

Please help me anyone one, please
Elden [556K]

Answer:

Step-by-step explanation:

Be sure to insert π where appropriate!

If the diameter of the yo-yo is 4 in, then the radius is 2 in.

The area comes from A = πr² and the circumference from C = πd.

In this case the area is A = π(2 in)² = 4π in² or 12.57 in².

The circumference is C = 4π in or 12.57 in.

Determine the slope of the line that passes though the points (2,-5) and (4,3).
schepotkina [342]

Answer: slope = 2

Step-by-step explanation:

The formula for calculating slope is given as :

m = \frac{y_{2}-y_{1}}{x_{2}-x_{1} }

x_{1}=2

x_{2}=4

y_{1}=-5

y_{2}=3

substituting into the formula , we have :

m = \frac{3-(-5)}{4-2}

m = \frac{8}{2}

m = 2

Therefore : slope = 2

1). What is the equation of the line that is perpendicular to y= -3x+1 that passes through the point (9,0)?
Bezzdna [24]

Answer:

Step-by-step explanation:

1) Slope of the given line = -3

slope of the perpendicular line = 1/3

y - 0 = 1/3(x-9)

y = 1/3x - 3

2) slope of the parallel line = -3

y - 0 = -3(x-9)

y = -3x + 27
