The moon is about 240,000 miles from earth . What is the distance written as a whole number multiplied by a power of ten
Murrr4er [49]
240,000 is a whole number. Now do the power of ten lol. Use a calculator. Remember don't do it all at once. The powers mean multiplying separate for example: 10×10 equals 100. I hundred times10 equals 1000. That is powered by three because it is multiplying 1030 different times which makes it the power. Simple math these days ha ha

To complete one round of a jogging track, Samantha took 1.52 minutes. Which expression below represents the time taken by Samant
OleMash [197]
As there is no sample expressions which could be the given answer we will solve it by the equation

(amount of time it takes to complete one round)*(number of rounds completed)=

We know that it took Samantha 1.52 minutes to go around once and assume that she continues this pace for 3 rounds. To solve for this we plug in our numbers into our equation.

1.52*3=<span>4.56</span> minutes to complete 3 rounds.

Does that answer your question?

Assume that the number of hours of daylight in New Orleans in 1994 is given by the function D(x) = 7 3 sin 2π 365 x + 35 3 , whe
Bas_tet [7]

Answer:

Here, the given function that represents the number of hours of daylight in New Orleans in 1994 is,

D(x) = \frac{7}{3} \sin \frac{2\pi }{365}x + \frac{35}{3}

Where,

x = the number of days after March 21

The number of days from 1 January to march 21 = 80

If x = -80, then,

D(-80) = \frac{7}{3} \sin \frac{2\pi }{365}(-80) + \frac{35}{3}

            =\frac{7}{3} \sin (-\frac{160 \pi}{365}) + \frac{35}{3}

            =-\frac{7}{3} \sin (\frac{160 \pi}{365}) + \frac{35}{3}

            =-\frac{7}{3}(0.98130)+\frac{35}{3}

           \approx 9.38

Therefore, the number of hours of daylight on January 1 are 9.38.

The number of days from march 21 to may 4 = 44

If x =44, then,

D(44) = \frac{7}{3} \sin \frac{2 \pi}{365}(44) + \frac{35}{3}

         =\frac{7}{3} \sin (\frac{88 \pi}{365}) + \frac{35}{3}

         =\frac{7}{3}(0.6870) + \frac{35}{3}

         \approx 13.27

Therefore, the number of hours of daylight on May 4 are 13.27.

The number of days from October 28 to may 4 = 221

If x = 221, then,

D(221) = \frac{7}{3} \sin \frac{2 \pi}{365}(221) + \frac{35}{3}

           =\frac{7}{3} \sin (\frac{442 \pi}{365}) + \frac{35}{3}

           =\frac{7}{3}(-0.6152)+\frac{35}{3}

           \approx 10.23

Therefore, the number of hours of daylight on October 28 are 10.23.
