6 0

Linear line is a straight line. In this equation which is in slope intercept form (y=Mx+b) M the number in front of the x is the slope (also known as common different) -3 is the slope, you do rise rise over run -3(down 3 to the right 1) or (up 3 to the left 1) and 3 is the y intercept. Y intercept is when x=0 (3,0). If you graph the point (3,0) you go down 3 to the right 1.

In the figure below AB is a diameter of circle P. What is the arc measure of minor arc AC in degrees?

arlik [135]

Answer:

$P = 139$

Step-by-step explanation:

See attachment for complete question

Required

Determine measure of Arc length AC

The interpretation of this question is to find P

If AB is the diameter, then

$P + 41 = 180$

$P + 41 - 41= 180 - 41$

$P = 139$

<em>Hence, the measure is 139 degrees</em>

A rectangular swimming pool that is 10 ft wide by 16 ft long is surrounded by a cement sidewalk of uniform width. If the area of

Alchen [17]

We are asked to solve for the width "x" in the given problem. To visualize the problem, see attached drawing.
We have the area of the swimming pool such as:
Area SP = l x w
Area SP = 10 * 16
Area SP = 160 feet2
Area of the swimming pool plus the sidewalk with uniform width:
Area SP + SW = (10 + x) * (16 + x)
160 + 155 = 160 + 10x + 16x + x2
160 -160 + 155 = 26x + x2
155 = 26 x + x2
x2 + 26x -155= 0
Solving for x, we need to use quadratic formula and the answer is 5 feet.

The value of x is <span>5 feet. </span>
