If water flows into the container at a constant rate of 6 cubic feet per minute, the rate at which the water level rising when the height of the water is 5 feet is; 0.688 ft/min

When we are given an equation that gives the relationship between two or more variables, then by differentiating the equation with respect to time would give us a new equation that involves the rate of change of each of the given variables.

We are given the dimensions of the tank as;

Radius; r = 4 feet

Height; h = 12 feet.

The water in the tank will also have a conical shape.

By similar triangles, we know that;

r/h = 4/12

r = h/3

Now the volume of the water is;

V = ¹/₃πr²h

Put h/3 for r in this volume equation to get;

V = ¹/₃π(h/3)²h

V = (1/27)πh³

Differentiating with respect to time gives;

dV/dt = (3/27)πh²(dh/dt)

We are given;

dV/dt = 6 cubic feet per minute

h = 5

Thus;

6 = (3/27)π(5²)(dh/dt)

dh/dt = 0.688 ft/min

Answer:

[tex]\text{GH} = 47[/tex]

Step-by-step explanation:

GH is one of the midsegments of triangle DEF. It divides both DE and EF to two equal segments (EH = HF, BG = GD).

A midsegment of a triangle has 3 characteristics:
- It splits the two sides it bisects into 2 equal segments.
- It is parallel to the side it doesn't bisect.
- It is equal to half the length of the side it doesn't bisect.

Applying the logic of the third characteristic, we can claim that GH = 1/2 * DF.

[tex]\text{GH} = \frac12\text{DF}\\\to 3x - 4 = \frac12 \times (9x - 59)\\\to 6x - 8 = 9x - 59\\\to 51 = 3x\\\to x = 17\\ \\\to \text{GH} = 3x - 4 = 3 \times 17 - 4 = 51 - 4 = 47[/tex]

The negative amortization at the end of year 1 is $2536.50

For the year 1 there will be still 12% rate of interest going on. There is a negative balance of $200 after payment of 1st month installment.

Thus negative amortization = FV(0.01x12 - 200)

Here 0.01 is the interest per month, 12 is the number of months in a year and -200 is the negative balance in first month

negative amortization = FV(0.01x12 - 200)

The negative amortization at the end of year 1 = $2536.50

Answer The sequence {an = (−a)n}

Step-by-step explanation:  The sequence {an = (−a)n} is bounded below by −1 and bounded above by 1, and so is bounded. This sequence does not converge, though; since |an − an+1| = 2 for all n, this sequence fails the Cauchy criterion, and hence diverges.

If the number of nickels in a piggy bank is 1 less than twice that of dimes and the total value of the coins is at least $4.35, then the smallest possible number of Nickels and Dimes is 43 and 22, respectively.

As per the question statement, The number of nickels in Bart's piggy bank is 1 less than twice the number of dimes, and the total value of the coins in this piggy bank is at least $4.35,

Then, we are required to determine the smallest possible number of individual coins in the bank.

To answer this question, first we will need to know the monetary values of nickels and dimes, that is,

(1 dime = 10 cents = $0.1), and (1 Nickel = 5 cents = $0.05).

Now let us assume that, there are "x" nickels and "y" dimes in that bank, Then as per the condition that, the number of nickels in Bart's piggy bank is 1 less than twice the number of dimes, we can write an equation with the above assumed two variables, which is, [x = (2y - 1)]...(i)

And as per the other condition that, the total value of the coins in this piggy bank is at least $4.35, we can write another equation, which is,

[(0.1y + 0.05x) = 4.35]

Or, [100(0.1y + 0.05x) = (100 * 4.35)]

Or, [(10y + 5x) = 435]...(ii)

Now substituting eqn (i) in eqn (ii), we get,

[{10y + 5(2y - 1)} = 435]

Or, [(10y + 10y - 5) = 435]

Or, [(10y + 10y) = (435 + 5)]

Or, (20y = 440)

Or, [y = (440/20)]

Or, (y = 22)

Therefore, [x = {(2 * 22) - 1}]

Or, [x = (44 - 1)]

Or, [x = 43]

That is, If the number of nickels in a piggy bank is 1 less than twice that of dimes and the total value of the coins is at least $4.35, then the smallest possible number of Nickels and Dimes is 43 and 22, respectively.

Answer:

$400

Step-by-step explanation:

Suppose Ahmad and Daryl both started with the same x amount of dollars.

Ahmad gains another 180 from his father, so he now has x+180 dollars.

Daryl spends 255, so he now has x-255 dollars.

After these events, Ahmad has 4 times as much money as Daryl, so

x+180=4(x-255)

Now we can solve for x to get the original amount of money.

x+180=4(x-255)

x+180=4x-1020

1200=3x

x=400

Both Ahmad and Daryl started with $400.

The values are given below,

Left Hand Limit i.e. lim x -> 1- f(x) = 3 ,

Right Hand Limit i.e. lim x -> 1+ f(x) = 1 ,

Function value at x = 1 i.e. f(1) = 1 ,

Left Hand Derivative lim x -> 1- f'(x)= -6 and

Right Hand Derivative lim -> 1+ f'(x) = -6.

So, the function f(x) is neither continuous nor differentiable at x = 1.

Given, a piecewise function

              3㏑(3 - 2x) + 3                for x < 1

f(x) =

                   -3x² + 4                      for x ≥ 1

Now, for lim x -> 1- f(x) we will consider the function  3㏑(3 - 2x) + 3, as we have to find the Left Hand Limit of the function, at x = 1.

lim x -> 1 3㏑(3 - 2x) + 3 = 3㏑(3 - 2(1)) + 3

= 3 ㏑(1) + 3

= 0 + 3

= 3

Now, for lim x -> 1+ f(x) we will consider the function -3x² + 4, as we have to find the Right Hand Limit of the function, at x = 1.

lim x -> 1 -3x² + 4 = -3(1)² + 4

= -3 + 4

= 1

Now, for f( 1 ) we will consider the function -3x² + 4,

f(1) = -3(1)² + 4

= -3 + 4

= 1

Now, for lim x -> 1- f'(x) we will consider the derivative of the function

3㏑(3 - 2x) + 3,

lim x -> 1 -6/(3 - 2x) = -6/(3 - 2(1))

= -6

Now, for lim -> 1+ f'(x) we will consider the derivative of the function

-3x² + 4,

lim x -> 1 -6x = -6(1)

= -6

So, the function f(x) is neither continuous nor differentiable at x = 1.

Hence, lim x -> 1- f(x) = 3 , lim x -> 1+ f(x) = 1 ,  f( 1 ) = 1 , lim x -> 1- f'(x) = -6 and lim -> 1+ f'(x) = -6.

The function is neither continuous nor differentiable at x = 1.

Answer:

Assuming every single ball has an equal chance of being drawn, then if B is the probability of drawing a blue ball and R is the probability of drawing a red ball:

B + R = 1,

since either a red or blue ball will be drawn. Since each ball has an equal chance of being drawn:

16 p = 1, or

p = 1/16

where p is the chance to draw a single ball. Since there are 10 red balls, there are ten independent and different ways to draw a red ball, which means that

R = 10 p = 10/16 = 5/8.

You can either apply the first equation to find that

B = 1 - R = 3/8

or state directly that

B = 6 p = 6/16 = 3/8

since there are six independent and different ways to draw a blue ball from the bag.

2089.17 rounded off to the nearest one is 2089

When you "round to the nearest _____" regardless of what is in the blank the steps are nearly always the same:

Identify which place value you are rounding off a number. The smaller the place value, the more accurate the final result shall be.

Find the next smallest place value, the digit to the right of the place value you're rounding off to. For example, if you want to round to the nearest ten you would have to find the number at the one's place.

If the digit in the next smallest place value is less than five (0, 1, 2, 3, or 4), you leave the digit you want to round off. Any digits after that number become zeros, or drop-offs if they're located after the decimal point. This is called rounding down a number or a sequence of numbers.

If the smallest place value is greater than or equal to five (5, 6, 7, 8, or 9), you increase the value of the digit you're rounding off to by one place (+1). Any remaining digits before the decimal point become zeroes, and any digits that are after the decimal point are dropped. This is called rounding up of numbers.

For example, for rounding off a number 838.274, depending on which place value you'll round to, the final rounded-off answer will vary. Rounding off 838.274:

Rounding off the nearest hundred is 800

Rounding off the nearest ten is 840

Rounding off the nearest one is 838

Rounding off the nearest tenth is 838.3

Consider, the given functions

f(x) = 3x - 1, g(x) = 4x^2 + 9

First to find f(g(x)).

Let,

f(g(x)) = 3(4x^2 + 9) - 1
