What is slope? Provide two examples of realistic situations where slope manifests itself. In each example make sure to state wha
erastovalidia [21]

Answer:

1. A slope is a surface of which one end or side is at a higher level than another; a rising or falling surface.

"he slithered helplessly down the slope"

Some real life examples of slope include: in building roads one must figure out how steep the road will be. skiers/snowboarders need to consider the slopes of hills in order to judge the dangers, speeds, etc. when constructing wheelchair ramps, slope is a major consideration.

4. The cosine function can be made to have the same values as the sine function for each angle by including a shifted _______ in
r-ruslan [8.4K]

Answer: Option D

phase

Step-by-step explanation:

By definition, the cosine function has the following form

y = cos (x - \phi)

Where \phi is known as the phase angle

By definition the sinx function is equal to the cosx function with a phase shift of \frac{\pi}{2}

So if we have the function

y = cos (x - \phi) and we want to transform it into the function y=sin(x) then \phi = \frac{\pi}{2}

Finally

y = cos(x - \frac{\pi}{2})=sin(x)

the answer is the option D

I'm stuck on this problem also
mash [69]
<span>The perimeter is 14.47
 
Since you have 3 vertices, the polygon you have is a triangle. The sides of the triangle will be XY, XZ, and YZ. Just use the pythagorean theorem to calculate the length of each side and then add the lengths together for the result. Side XY = sqrt( (-1-3)^2 + (3-0)^2) = sqrt(16+9) = sqrt(25) = 5 Side XZ = sqrt ( (-1-(-1))^2 + (3-(-2))^2) = sqrt(0+25) = sqrt(25) = 5 Side YZ = sqrt( (3-(-1))^2 + (0-(-2))^2) = sqrt(16 + 4) = sqrt(20) = 4.47 Now add the length of each side together 5 + 5 + 4.47 = 14.47</span>
