Answer:

The first graph (ellipse) is not a function.

Step-by-step explanation:

Consider the provided graphs.

We need to determine which is not a function.

The vertical line test can be used to determine whether a graph represents a function.

If the vertical line intersect the graph more than one point then the graph is not a function.

Now consider the figure 1.

The first graph intersect the vertical line 2 times.

Therefore, the first graph (ellipse) is not a function.

Answer:

The ellipse is not the graph of a function.

Step-by-step explanation:

If you can draw a vertical line on the graph that intersects the graph in two or more points, the relation shown is <em>not a function</em>.

A vertical line will intersect the ellipse at two points (unless it is tangent to an end of the major axis), so the ellipse is not the graph of a function.

Grady marks down some $4.09 pens to $3.59 for a week and then marks them back up to $4.09. Find the percent of increase and the

emmainna [20.7K]

Answer:

Percentage decrease ( from $4.09 to $3.59) is 0.1% ( Rounded to nearest tenth)

Percentage increase (from $3.59 to 4.09) is 0.1% ( Rounded to nearest tenth)

Percentages are not same for the both price changes. As we can see from the calculations percentage change from $3.59 to $4.09 is higher.

Step-by-step explanation:

$4.09 has been changed to $3.59.

Percent change = [(Value after - Value before) / Value before]*100

= $\frac{3.59-4.09}{4.09}*100$ %

= $\frac{-0.5}{4.09}*100$ %

= $-0.122249$ %

= $-0.1$ % ( Rounded to nearest tenth)

Percentage decrease is 0.1% ( Rounded to nearest tenth)

Now lets calculate the percentage change from $3.59 to $4.09.

Percent change = [(Value after - Value before) / Value before]*100

= $\frac{4.09-3.59}{3.59}*100$ %

= $\frac{0.5}{3.59}*100$ %

= $0.13927$ %

= $0.1$ % ( Rounded to nearest tenth)

Percentage increase is 0.1% ( Rounded to nearest tenth)

Percentages are not same for the both price changes. As we can see from the calculations percentage change from $3.59 to $4.09 is higher.

One hour on earth is four hours on planet S.

Andreas93 [3]

Answer:

The answer is 60 hours.

Step-by-step explanation:

We could use proportions to solve.

$\frac{1 \: hour \: on \: earth}{4hours \: on \: planet \: s} = \frac{x}{240hours \: on \: planet \: s}$

$4 \times x = 4x \\ 1 \times 240 = 240$

$\frac{4x}{4} = \frac{240}{4} \\ x = 60$
