Luis counts the total number of ducks swimming on a pond each day. On Monday he counts 1 duck. On Tuesday he counts 2 ducks. On
Papessa [141]

The pattern is:     Ducks always swim on that pond <em><u>in powers of 2</u></em> .

Monday ........ 2⁰ =  1
Tuesday ........ 2¹ =  2
Wednesday ... 2² =  4
Thursday ....... 2³ =  8

So
Friday ........... 2⁴ =  16
<em>Saturday ...... 2⁵ =  32</em>        <=== the answer  

AND ...
If they kept doing this for a month, then
on the 31st day there would be

       2³⁰ = <em>1,073,741,824</em> (more than 1 billion) ducks out there !

Use the arc length formula to find the length of the curve y = 4x − 5, −1 ≤ x ≤ 3. Check your answer by noting that the curve is
Reptile [31]

Answer:

4\sqrt{17}

Step-by-step explanation:

Let's find the answer by using the arc length formula which is:

\int\limits^a_b {\sqrt{1+(\frac{dy}{dx})^{2} } } \, dx

First, let's find dy/dx which is:

y=4x-5

y'=4*(1)-0

y'=4, now let's use the formula:

\int\limits^3_{-1} {\sqrt{1+4^{2}} } \, dx=\sqrt{17} *(3-(-1))=4\sqrt{17}

Now, using the distance formula we have:

d=\sqrt{(x2-x1)^{2} +(y2-y1)^{2} }

y(-1)=4*(-1)-5=-9 \\y(3)=4*(3)-5=7

So we have two points (-1, -9) and (3, 7) so:

d=\sqrt{(3-(-1))^{2} +(7-(-9))^{2} }=4\sqrt{17}

Notice both equations gave the same length 4\sqrt{17}.

Matt, a 180 pound (82 kg) male, goes to a party and is served beer in a 16-ounce (473 ml) red plastic cup. he has 3 cups of beer
goblinko [34]

4 Standard drinks he has consumed in over a two - hour time period.

<h3>What is Unitary Method?</h3>

The unitary method is a method in which you find the value of a unit and then the value of a required number of units.

For example: 5 cars have price of $500. what will be the price of 10 cars.

Now, we know

5 cars → $500

1 car → $500/5

1 car → $100

10 cars → 8 x $100

10 cars → $800

The standard drink contains 12 - ounce of beer.

Here, we have given 1 red cup which has 16 - ounce of beer.

He has 3 red cups.

So, total ounce of beer he has consumed in two hour time period:

16 x 3 = 48 ounce of beer.

Now, as we know standard drink contains 12 - ounce of beer.

so, Number of standard drink = 48/12 = 4

Hence, 4 Standard drinks he has consumed in over a two - hour time period.
