Question 1(Multiple Choice Worth 5 points)
Nadusha1986 [10]

Answer: arc\ length =13.19cm

Step-by-step explanation:

You need to use the following formula:

arc\ length=r\theta

Where "r" is the radius and \theta is is the central angle of the arc in radians.

Assuming that that the angle \frac{3\pi }{5} is the central angle of the arc, and knowing that the radius is 7 centimeters, you can substitute values into the formula.

Therefore, you get:

arc\ length=r\theta\\\\arc\ length= (7cm)(\frac{3\pi}{5})}\\\\arc\ length =13.19cm

Line l passes through point (3,−26) and line p is the graph of y−3=−5(x−2) .
uranmaximum [27]

Considering the definition of parallel line, the equation of line l is y= -5x -11.

<h3>Linear equation</h3>

A linear equation o line can be expressed in the form y = mx + b

where

  • x and y are coordinates of a point.
  • m is the slope.
  • b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.

<h3>Parallel line</h3>

Parallel lines are two lines that are always at the same distance from each other.

Two lines are parallel if they have the same slope and different y-intercepts. This is, they have the same value of m and different value of b.

<h3>Equation of parallel line in this case</h3>

In this case, the line is y−3=−5(x−2) Expressed in the form y = mx + b, you get:

y−3=−5x−2×(-5)

y−3=−5x+ 10

y=−5x+ 10 + 3

<u><em>y=  -5x +13</em></u>

where:

  • the slope is -5.
  • the y-intercept is 13.

Two lines are parallel if they have the same slope. So, the parallel line has a slope of -5 and has a form of: y= -5x + b

The line passes through the point (3, -26). Replacing in the expression for parallel line:

-26= -5× 3 + b

-26= -15 + b

-26 + 15 = b

<u><em>-11 = b</em></u>

Finally, the equation of parallel line is y= -5x -11.
