Marty and Ethan both wrote a function, but in different ways.
lisabon 2012 [21]

Answer:

Marty's function has larger slope as compared to Ethan's slope.

Step-by-step explanation:

Marty function:

y plus 3 equals StartFraction 1 Over 3 EndFraction left-parenthesis x plus 9 right-parenthesis.

Writing in mathematical form: y+3=\frac{1}{3}(x+9)

Marty has written expression in point-slope form: y-y_1=m(x-x_1) where m is slope

So, comparing Marty's equation with general point-slope form equation we get slope m=\frac{1}{3}\:or\: 0.3

Now, Ethan has a table

x        y

-4      9.2

-2      9.6

0       10

2       10.4

We can find slope using formula: Slope=\frac{y_2-y_1}{x_2-x_1}

Using any two points, we can find slope of Ethan's equation

Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{9.6-9.2}{-2-(-4)} \\Slope=\frac{0.4}{-2+4} \\Slope=\frac{0.4}{2} \\Slope=0.2

So, we get Marty's slope = 0.3

Ethan's slope = 0.2

So, Marty's function has larger slope as 0.3 is greater than 0.2

If you interpret the question as is, the answer is in the thousands which is not listed. The last part of the question should read “the number of new cases doubled from those newly identified cases from the day prior.” It was poorly phrased lol
Day 1: 5
Day 2: 5+10
Day 3: 15+20
Day 4: 35+40
Day 5: 75+80
Day 6: 155+160
Which is 315 at the end of the 6th day

Mr. Doyle mowed 2\5ths of his lawn. His son mowed 1\3rd of it. Who mowed most of the lawn? How much of the lawn still needs to b
kondor19780726 [428]

Answer:

Step-by-step explanation:

Dad:  2/5

Son:  1/3

<u>Who mowed most of the lawn? </u> Dad, of course.  2/5 is larger than 1/3.  2/5 is 40% and 1/3 is 33.333%

<u>How much of the lawn still needs to be mowed?  </u>

 2/5 + 1/3 + X = 1  [1 means the whole lawn.  X is the remaining portion.]

6/15 + 5/15 + X = 1   [Convert each fraction so that they have a com,mon denominator.  This also shows that 2/5 (6/15) is larger than 1/3 (5/15).

11/15 + X = 1

X = 1 - 11/15

X = 4/15 left to be mowed.

<u>How much does Mr. Doyle have left to mow?</u>

We'll assume each rate is the same, 2/5 for Dad and 1/3 for son.

4/15 left to be mowed.

Dad will mow 2/5 of 4/15, so (2/5)*(4/15) = 8/75 left of the original yard

Son will mow 1/3 of 4/15, so (1/3)*(4/15) = 4/45 left of the original yard
