If r= 1 and 0 = 5 pie/4, what is the approximate arc length?
A. 1.25 units
B. 4.189 units
C. 3.927 units
D. 3.665 units

Answers

9514 1404 393

Answer:

  C.  3.927 units

Step-by-step explanation:

The arc length (s) is given by ...

  s = r·θ

  s = 1·5π/4 ≈ 3.92699

  s ≈ 3.927 . . . units

The length of the given arc is 3.927 units, so the correct option is C.

How to get the arc length?

For an arc in a circle of radius R, defined by an angle θ, the length is:

L = θ*R

In this case, we have:

R = 1 unit.

θ= (5/4)pi

Where pi = 3.14159

Replacing that in the length equation we get:

L = (5/4)*3.14159*(1 unit) = 3.927 units.

So the correct option is C.

What is a graph?

The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.

These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.

5. The graph of this function is constant for all values of x, y = 3.

6. The graph of this function has points (0, 3) and (3, 2).

m = (2 - 0)/(3 - 0).

m = 2/3.

2 = (2/3)×3 + b.

2 = 2 + b.

b = 0.

y = (2/3)x.

7. The graph of this function has points (0, 1) and (3, 2).

m = (2 - 0)/(3 - 1).

m = 2/2.

m = 1.

2 = 1(3) + b.

2 = 3 + b.

b = -1.

y = x - 1.

8. The graph of this function has points (- 3, 0) and (0, 3).

m = (3 - 0)/(0 + 3).

m = 1.

3 = 1(0) + b.

b = 3.

y = x + 3.

9. The graph of this function is a vertical line parallel to the y-axis,

x = 3.

10. The graph of this function has points (0, 0) and (- 1, 3).

m = (3 - 0)/(- 1 - 0).

m = 3/ - 1.

m = - 3.

0 = - 3(0) + b.

b = 0.

y = - 3x.

Answer:

Step-by-step explanation:

(2) y=2x is a proportional relationship. It is of the form y=kx, where k is the constant of proportionality.

The three inside angles (A, B and C) of a right angled triangle are in the ratio 7:18:11

The smallest angle is 35°

Work out out angles a,b and ,

Answers

Answer:

Angle A =35 degrees, Angle B = 90 degrees, and Angle C = 55 degrees

Step-by-step explanation:

So all the angles added up would be 180. Let's use the variable x. The angles would be 7x, 18x, and 11x.

The smallest angle is 35, and 7x is the smallest out of all them since x has to be positive.

7x = 35

x = 5

Then substitute x into each angle.

They would be 35 degrees, 90 degrees, and 55 degrees
