<h2>Answer:</h2>

The statement which describes the intercepts on the graph is:

B.    The initial velocity of the runner was 2 m/s, and the runner stopped after 8 seconds.

<h2>Step-by-step explanation:</h2>

The graph shows shows the velocity f(t) of a runner during a certain time interval.

The slope of this graph between different points will give us the acceleration of the runner.

Now, based on the graph we observe that when t=0 the velocity of the runner was: 2 m/s

( since, the point on the graph is: (0,2) )

Also, the velocity of the runner is zero when t=8 seconds.

Since, the point on the graph is at (8,0)

Hence, the runner stops after 8 seconds.

Polygon ABCD reflects about line to make polygon EFGH. What is the length of ? A. 2 units B. 2.2 units C. 3 units D. 3.2 units
Mademuasel [1]

Answer:

A) LEngth of FG is 2 units

Step-by-step explanation:

Considering the diagram attached below.

Reflection of any polygon does not affects its length.

As it is given both polygons are reflection of each other so their sides are congruent.

AB ≅ EF = 3 units

BC ≅ FG = 2 units

CD ≅ GH = 2.2 units

DA ≅ HE = 3.2 units

The expression represents the cost of Janelle’s cell phone bill, where m represents the number of minutes of use. 0.05m + 12 Wha
inn [45]

Answer:

The constant in the expression is 12

Step-by-step explanation:

The constant of the expression is the value that is independent of the number of minutes Janelle uses. The expression can  be written as :

f(m)=0.05m +12

Example if m is 1 or 2

f(1) = 0.05(1) +12 = 12.05

f(2= = 0.05*2 +12 =0.1 +12 = 12.1

The value 12 is the minimum price of the bill indepent of the consumption of minutes of Janelle. She will always be charged this value.
