Which function is described by values in the table?

Mathematics

One way to approach this problem is to go ahead and find the actual equation in slope-intercept form.


The slope of the line thru (3,6) and (5,4) is m = (6-4) / (3-5), or -2/2, or -1.

Subbing the known values of m, x and y, we get:

4 = -(5) + b. Then b = 9.

The correct equation (representing the data values in the table) is y = -x + 9.

How do I do this question
s344n2d4d5 [400]

The two laws of motion are

\text{Low:}\ d=v_lt\\\text{Sim:}\ d=v_st

Since Mr Sim's speed is 15 km/h less that Mr Low's, we have

\text{Low:}\ d=v_lt\\\text{Sim:}\ d=(v_l-15)t

Note that the distance d is the same for both equations, because they traveled the same path.

20 minutes is 1/3 of a hour, so at t=1/3 Mr Low traveled the whole distance, while at the same time Mr Sim traveled 4/5 of the distance:

\text{Low:}\ d=\dfrac{v_l}{3}\\\text{Sim:}\ \dfrac{4d}{5}=\dfrac{(v_l-15)}{3}

If we multiply Sim's equation by 5/4, we have

\text{Low:}\ d=\dfrac{v_l}{3}\\\text{Sim:}\ d=\dfrac{5(v_l-15)}{12}

Since the left hand sides are equal, we equal the right hand side as well:

\dfrac{v_l}{3}=\dfrac{5(v_l-15)}{12}

Multiply both sides by 12:

4v_l=5(v_l-15)

Expand the right hand side:

4v_l=5v_l-75 \iff v_l = 75

Which implies

v_s=v_l-15=75-15=60

\sqrt[3]{8m}^3

  • Set up

(8m^{\frac{1}{3}})^3

  • Convert the radical into a fractional exponent using \sqrt[n]{x^m} = x^{\frac{m}{n}}

8m^{(3 \cdot \frac{1}{3})}

  • Use the property that (x^a)^b = x^{(a \cdot b)}

8m

  • Simplify

The simplification would be 8m.
