It would take the second computer 75 seconds because:

$\frac{1}{30} - \frac{1}{50} = \frac{1}{75}$

The cost of using a game facility is $1 for every 12 minutes. Talisa writes the function for the cost per hour as ()=. Explain T

Anna [14]

Using proportions, it is found that Talisa's error was at calculating the cost per minute of the game.

In the function:

The input is x, which is the number of minutes.

The output is f(x), which is the cost of playing the game for x minutes.

Talisa's expression is given by:

$f(x) = 12x$

The cost of using a game facility is <u>$1 for every 12 minutes</u>, hence, the cost per minute is:

$c = \frac{1}{12}$

And the correct expression for the cost is:

$f(x) = \frac{x}{12}$

Hence, it can be seen that Talisa's error was at calculating the cost per minute of the game.

1.2) Q5.) The graph is a transformation of one of the basic functions. Find the equation that defines the function.

Yuri [45]

The graph starts at around x = 0. At x = 0, the graph's y-value is 2. There are no x-values that are less than 0.

The graph crosses the following points: (1,1); (4,0); (9, -1)

The distance between each y-value is exponentially increasing, as the slope of the graph is slowly decreasing as x approaches infinity.

Based on this information, we can say that this graph is a transformation of the base function, y = √x

To determine the transformations made, we need to compare the graph to the original base function (attached below).

The basic function starts at 0, and has a positive slope. It reaches the points (1,1); (4,2); and (9,3).

The graph in the question shows the function start at 2, and the negative slope reaching the points mentioned earlier in the answer.

Based on this information, we can conclude that y = -√x + 2.

Jack is trying to make extra money on his summer vacation from school. He works two different jobs, earning $9 per hour washing

Sveta_85 [38]

Answer:

$57

$9w+6d$

Step-by-step explanation:

Given that:

Earnings per hour for washing cars = $9

Earnings per hour for walking dogs = $6

Number of hours for which car washing is done = $w$

Number of hours taken for walking dogs = $d$

Earnings for $w$ hours for washing cars = Per hour earnings multiplied by number of hours = $9 $w$

Earnings for $d$ hours for walking dogs = Per hour earnings multiplied by number of hours = $6 $d$

Total earnings by both = $( $9w+6d$ )

Now, given that

Number of hours spent washing cars = 5 hours

Number of hours spent walking dogs = 2 hours

Therefore, total earnings by both = 9 $\times$ 5 + 6 $\times$ 2 = <em>$57</em>
