Describe the slope of the line<br> Find the slope
Dmitry_Shevchenko [17]

Answer:

Question one: Zero slope
Question two: m=\frac{0}{4}

Step-by-step explanation:

Given the following questions:

<u>Question one:

</u>The following line is what you call a "zero slope." Zero slopes are lines that are neither decreasing or increasing and remain at a constant or just a straight line.

Question two:

Point A = (-2, -3) = (x1, y1)
Point B = (2, -3) = (x2, y2)

Using the formula for slope or rise over run we will solve and find the slope of this line.

m=\frac{y2-y1}{x2-x1}
m=\frac{-3--3}{2--2} =\frac{0}{4}
m=\frac{0}{4}

The slope of this line is "0/4."

Hope this helps.

eimsori [14]

Answer:

Step-by-step explanation:

This is classic right triangle trig.  The height of the hill is 78.4 which serves as the side opposite the reference angle of 23 degrees.  The side we are looking for is the hypotenuse of that triangle.  The trig ratio that relates the side opposite a reference angle to the hypotenuse of the right triangle is the sin ratio.  Setting it up using our values:

sin(23)=\frac{78.4}{x}, where x is the unknown length of the hypotenuse.  Solving for x:

x=\frac{78.4}{sin(23)}

Make sure your calculator is in degree mode before entering this in.  You will get a length of the hypotenuse as 200.649 feet, so choice A.
