You burn 265 calories running and then 7 calories per minute swimming.

Your friend burns 273 calories running and then 11 calories per minute swimming.

Let us assume that both of you swim for x minutes.

Calories burnt by you = 265+7x

Calories burnt by your friend = 273+11x

Difference between both = 273+11x-(265+7x)

= 273+11x-265-7x

= 8+4x

I need the parent function and the transformation with some explanation, thank you.

True [87]

Answer:

parent: y = x²
transformed: y = -3x² +4

Step-by-step explanation:

You have correctly recognized that the function is quadratic, so has parent function y = x².

You may notice that the function drops by 3 units when x increases or decreases by 1 unit from the vertex. That factor (-3) is the vertical scale factor in the transformed function ...

f(x) = a(x -h)² +k

where "a" is the vertical scale factor and (h, k) is the location of the vertex of the transformed function.

We note that the graphed function has its vertex at (h, k) = (0, 4), so the complete transformed function with a=-3, h=0, k=4 is ...

f(x) = -3x² +4

Use IF functions to calculate the regular pay and overtime pay based on a regular 40-hour workweek in cells E5 and F5. Pay overt

g100num [7]

Excel formulas are expressions used to perform computation.

The Excel formula to enter in cell E5 is =IF(D5<$B$21,D5,$B$21) * C5
The Excel formula to enter in cell E5 is =IF(D5>$B$21,(D5-$B$21) * C5 * $B$22, 0)

<h3 /><h3>The regular pay</h3>

From the complete question, cell B21 represents base work hour

So, we start by checking if the work hour in cell D5 is less than the base work hour in cell B21

If yes, the work hour remains D5; otherwise the work hour is cell B21

The work hour is then multiplied by the rate in cell C5

Hence, the Excel formula to enter in cell E5 is =IF(D5<$B$21,D5,$B$21) *

<h3>The overtime pay</h3>

Here, we start by checking if the work hour in cell D5 is greater than the base work hour in cell B21

If yes, the overtime hour the difference between D5 and B21; otherwise the overtime hour and pay is 0

The over time hour if there is, is then multiplied by the rates in cells C5 and B22

Hence, the Excel formula to enter in cell E5 is =IF(D5>$B$21,(D5-$B$21) * C5 * $B$22, 0)
