A water tank has the shape of a horizontal cylinder with radius 1 meter and length 2 meters. If water is being pumped into the tank at a rate of 5 I cubic meters per minute, find the rate at which the water level is rising when the water is 5 C meters deep. Simplify your answer completely.

Answers

Step-by-step explanation:

The answer is dhdt=325πmmin.

With related rates, we need a function to relate the 2 variables, in this case it is clearly volume and height. The formula is:

V=πr2h

There is radius in the formula, but in this problem, radius is constant so it is not a variable. We can substitute the value in:

V=π(5m)2h

Since the rate in this problem is time related, we need to implicitly differentiate wrt (with respect to) time:

dVdt=(25m2)πdhdt

In the problem, we are given 3m3min which is dVdt. So we substitute this in:

dhdt=3m3min(25m2)π=325πmmin

A water tank currently contains 275 gallons of water. The amount of water in the tank will decrease at a constant rate of 15 gallons per week.
Which function can be used to find t, the total number of gallons of water in the tank after w weeks?

F t = 15w - 275
G t = -15w + 275
H t = 275w - 15
J t = -275w + 15

Answers

Answer:

I would think its C

Step-by-step explanation:

Since you are subtracting 15 from 275, it would be 275-15

i am assuming you dont need any help on the variables, so I hope this helps :)

If i am wrong, please let me know :DD

have a nice day, *insert preferred referral here*!!

The function that can be used to evaluate 't', the total number of gallons of water in the tank after w weeks is G(t) = 275 - 15w and this can be determined by using the given data.

Given :

A water tank currently contains 275 gallons of water. The amount of water in the tank will decrease at a constant rate of 15 gallons per week.

The following steps can be used in order to determine the function that can be used to evaluate 't', the total number of gallons of water in the tank after w weeks:

Step 1 - Let the total number of weeks be 'w'.

Step 2 - So, the total amount of water reduced from the tank is:

= 15w

Step 3 - So, the function that can be used to evaluate 't', the total number of gallons of water in the tank after w weeks is given below:

G(t) = 275 - 15w

Therefore, the correct option is B).

Correct answer please ​

Answers

[tex] \green{\large\underline{\sf{Solution-}}}[/tex]

Given expression is

[tex]\rm :\longmapsto\:\dfrac{5 \times {25}^{n + 1} - 25 \times {5}^{2n} }{5 \times {5}^{2n + 3} - {25}^{n + 1} } [/tex]

can be rewritten as

[tex]\rm \:  =  \: \dfrac{5 \times { {(5}^{2} )}^{n + 1} - {5}^{2} \times {5}^{2n} }{5 \times {5}^{2n + 3} - {( {5}^{2} )}^{n + 1} } [/tex]

We know,

[tex] \purple{\rm :\longmapsto\:\boxed{\tt{ {( {x}^{m} )}^{n} \: = \: {x}^{mn}}}} \\ [/tex]

And

[tex] \purple{\rm :\longmapsto\:\boxed{\tt{ \: \: {x}^{m} \times {x}^{n} = {x}^{m + n} \: }}} \\ [/tex]

So, using this identity, we

[tex]\rm \:  =  \: \dfrac{5 \times {5}^{2n + 2} - {5}^{2n + 2} }{{5}^{2n + 3 + 1} - {5}^{2n + 2} } [/tex]

[tex]\rm \:  =  \: \dfrac{{5}^{2n + 2 + 1} - {5}^{2n + 2} }{{5}^{2n + 4} - {5}^{2n + 2} } [/tex]

can be further rewritten as

[tex]\rm \:  =  \: \dfrac{{5}^{2n + 2 + 1} - {5}^{2n + 2} }{{5}^{2n + 2 + 2} - {5}^{2n + 2} } [/tex]

Hence,

Answer:

8/21 . 5/16 = 5/42

12/25 . 15/16 = 9/20

Step-by-step explanation:

16 = 2 x 8

8/21 . 5/16

= ( 8 x 5 ) / ( 21 x 16 )

= ( 8 x 5 ) / ( 21 x 2 x 8 )

= 5 / ( 21 x 2 )

= 5/42

12 = 3 x 4

15 = 3 x 5

25 = 5 x 5

16 = 4 x 4

12/25 . 15/16

= ( 3 x 4 ) / ( 5 x 5 ) . ( 3 x 5 ) / ( 4 x 4 )

= ( 3 x 4 x 3 x 5 ) / ( 5 x 5 x 4 x 4 )

= ( 3 x 3 ) / ( 5 x 4 )

Answer:

Slope = -4

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes, which means that multiplying their slopes result in a product of -1. Given the equation, x - 4y = - 12:

Transform the equation into its slope-intercept form, y = mx + b:

x - 4y  = - 12

x - x - 4y = - x - 12

-4y = -x - 12

Divide both sides by -4:

[tex]\frac{-4y}{-4} = \frac{-x - 12}{-4}[/tex]

y =  ¼x + 3  ⇒ (This is the slope-intercept form of the given standard equation, x - 4y  = - 12).

Since the slope of the given equation is ¼, then it means that its negative reciprocal must be - 4:

(¼) (-4) = -1

Therefore, the slope of the line perpendicular to x - 4y = - 12 is - 4.

it’s 1/4 because if you apply the formula you just get that so m=1/4

About how many miles per gallon of gasoline did they average on their trip?

Answers

Answer: 27.049 mpg approximately

Work Shown:

(384.1 miles)/(14.2 gallons) = (384.1)/(14.2) mpg = 27.049 mpg approximately

mpg = miles per gallon

Answer:

27.05 miles per gallon

Step-by-step explanation:

384.1 miles = 14.2 gallons

x = 1 gallon

Mateo jogs for 3 3/4 miles on Saturday and 4 2/5 miles on Sunday. What is the total distance, in miles, that Mateo jogged in the past 2 days?

Answers

Answer:

Mateo jogged 8 3/20 miles in the past 2 days.

Step-by-step explanation:

Given:-

Distance on Saturday = 3 3/4

Distance on Sunday = 4 2/5

Total distance = 3 3/4 + 4 2/5

                       = 15/4 + 22/5

                       = LCM of deniminators (20)

                       = 75/20 + 88/20

                       = (75 + 88)/20

                      =  163/20

Ohio (1957): In May 1957, three police officers arrived at Dollree Mapps home after having received a tip that a fugitive had hidden there. Mapp, who had phoned her attorney, refused to admit the police officers. Three hours later, they knocked on the door, and when Mapp did not immediately answer, they forced the door open and entered. Mapp demanded to see a search warrant. One of the officers held up a piece of paper, claiming it was the warrant. After a scuffle, the officers handcuffed Mapp. The police then began to search the house. They did not find a fugitive in the house; however, in the course of their search they turned up some material they deemed obscene. Mapp was charged and eventually convicted of having offensive books and pictures in her possession. Engel v. Vitale (1962): In 1951 the New York State Board of Regents, which supervises the states public school system, approved a brief prayer at the start of each day. The prayer read: Almighty God, we acknowledge our dependence upon Thee, and we beg Thy blessings upon us, our parents, our teachers, and our Country. School districts were not required to use the prayer, and students were not required to recite it. In 1958, the New Hyde Park school board adopted the prayer and directed that it be recited each day in every class, although students could be excused from reciting it. Steven Engel, the parent of two children in the New Hyde Park schools, objected to this practice and asked a state court to order the prayer dropped. Tinker v.

In December of 1965, John Tinker, his sister Mary Beth, and their friend Christopher Eckhardt decided to protest the war. They planned to wear black armbands to their schools in Des Moines, Iowa. When the school board learned of their plans, it adopted a policy that banned the wearing of armbands. Any students who violated this policy would be suspended.

[ Read the passage now]---> Except from James Polk's 1845 Inaugural Address: Eighty years ago population was confined on the west by the ridge of the Alleghenies. Within that period... our people... have filled the eastern valley of the Mississippi, adventurously ascended the Missouri to its headsprings, and are already engaged in establishing the blessings of self-government in valleys of which the rivers flow to the pacific. The world beholds the peaceful triumphs of the industry of our emigrants. To us belongs the duty of protecting them adequately wherever they may be upon our soil. U.S. Army Officer, Regarding the April 24, 1847, Skirmish Between Mexican and American Forces. We have not one particle of right to be here. It looks as if the government sent a small force on purpose to bring a war, so as to have a pretext for taking California and as much of this country as it chooses. Excerpts from Polk's Message to congress, May 11, 1846: The existing state of the relations between the United States and Mexico renders it proper that I should bring the subject to the consideration of Congress. The strong desire to establish peace with Mexico on liberal and honorable terms, and the readiness of this Government to regulate and adjust our boundary and other causes of difference with that power on such fair and equitable principles as would lead to permanent relations of the most friendly nature. The Mexican Government not only refused to receive him [ the U.S. envoy] or listen to his propositions, but after a long-continued series of menaces have at last invaded our territory and shed the blood of our fellow-citizens on our own soil. I had ordered an efficient military force to take a position between the Nueces and the Del Norte. This had become necessary to meet a threatened invasion of Texas by the Mexican forces. The invasion was threatened solely because Texas had determined, in accordance with a solemn resolution of the Congress of the United States, to annex herself to our Union, and under these circumstances it was plainly our duty to extend our protection over her citizens and soil. Texas, by the final action of our Congress, had become an integral part of our Union. The Congress of Texas, by its act of December 19, 1836, had declared the Rio del Norte to be the boundary of that Republic. Our own Congress had, moreover, with great unanimity, by the act approved December 31, 1845, recognized the country beyond the Nueces as a part of our territory. Accordingly, on the 13th of January last instructions were issued to the general in command of these troops to occupy the left bank of the Del Norte. This river, which is the southwestern boundary of the State of Texas, is an exposed frontier. The Army moved from Corpus Christi on the 11th of March, and on the 28th of that month arrived on the left bank of the Del Norte opposite to Matamoras, where it encamped on a commanding position, which has since been strengthened by the erection of fieldworks. General Ampudia... notified General Taylor to break up his camp within twenty-four hours and to retire beyond the Nueces River, and in the event of his failure to comply with these demands announced that arms, and arms alone, must decide the question. A party of dragoons of 63 men and officers were... dispatched from the American camp up the Rio del Norte, on its left bank. to ascertain whether the Mexican troops had crossed or were preparing to cross the river, became engaged with a large body of these troops, and after a short affair, in which some 16 were killed and wounded, appear to have been surrounded and compelled to surrender. The grievous wrongs perpetrated by Mexico upon our citizens throughout a long period of years remain unredressed, and solemn treaties pledging her public faith for this redness have been disregarded. Mexico has repeatedly threatened to make war upon us for the purpose of reconquering Texas. In the meantime we have tried every effort at reconciliation. Mexico... has invaded our territory and shed American blood upon the American soil. She has
