Answers

Answer 1

Answer:

30x^2

Step-by-step explanation:

The least common multiple (LCM) of two or more non-zero whole numbers is the smallest whole number that is divisible by each of those numbers. In other words, the LCM is the smallest number that all of the numbers divide into evenly.

I'm trying to find the explicit form of an equation after performing an integration. I'm a bit rusty.

ln|y| = C - cos(x)

C is an arbitrary constant.

Is it:

y = e^(c-cos(x))

or because it's an arbitrary constant, can it be written:

y = C - e^(cos(x))

Thanks.

Answers

No, it should be written as

[tex]y = Ce^{-\cos x}[/tex]

Provided that y ≠ 0, both solutions

[tex]y = e^{C-\cos(x)}[/tex]

and

[tex]y = Ce^{-\cos(x)}[/tex]

are correct. The other solution you provided,

[tex]y = C - e^{\cos(x)}[/tex]

is not.

The only difference between the "valid" solutions lies in the particular value of the arbitrary constant C.

Suppose y(0) = Y ≠ 0 is given as an initial condition. Then in the first solution,

[tex]Y = e^{C - \cos(0)} \implies \ln|Y| = C - 1 \implies C = \ln|Y| + 1[/tex]

In the second solution,

[tex]Y = C e^{-\cos(0)} \implies Y = Ce^{-1} \implies C = eY[/tex]

But both solutions are the same, since

[tex]y = e^{\ln|Y| + 1 - \cos(x)} = e^{\ln|Y|} e^1 e^{-\cos(x)} = eY e^{-\cos(x)}[/tex]

First, unmix the mixed numbers.

-9/4 = -2 1/4.

Which is greater?

1/4 vs. 3/5

Answer: 3/5 So...

-2 3/5 would be the least.

Then there would be -2 1/4

Then, it would be 1.2 because 1.2 is smaller than 7/4.

Therefore, this pattern would be the correct answer...

Answer:

  (x, y, P) = (4/3, 8/3, 112/3)

Step-by-step explanation:

In standard form, the constraints are all "less than or equal to", the variables are all non-negative, and the objective is maximization. This problem is presented in standard form.

  4x +y ≤ 8

  x +4y ≤ 12

  x ≥ 0; y ≥ 0

maximize P = 6x +11y

__

Now we add the slack variables to make the constraints be "equal to". These have a coefficient of +1, and they, too, are non-negative. Here, we'll use s and t as the slack variables.

  4x +y +s = 8

  x +4y +t = 12

These equations, together with the objective function, are combined in a matrix-like "tableau" in which each row is the set of coefficients in one of the equations. Here, the columns represent x, y, s, t, P and the constants. The equation for the objective function is negated so we're trying to minimize that, as well.

  [tex]\begin{array}{ccccc|c}4&1&1&0&0&8\\1&4&0&1&0&12\\-6&-11&0&0&1&0\end{array}[/tex]

Find the column with the most negative value on the bottom row. (Column 2) Divide the rightmost column by this column and find the smallest quotient. Here, the quotients are 8/1 = 8, and 12/4 = 3. The smallest is 3. This identifies the 4 in column 2, row 2 as the "pivot."

Now, row operations are performed to make the pivot be 1 and other values in the pivot column be zero. This gives a new tableau. For example, the new values in row 1 are ...

  4 -1/4, 1 -4/4, 1 -0/4, 0 -1/4, 0 -0/4, 8 -12/4

The new tableau is ...

  [tex]\begin{array}{ccccc|c}15/4&0&1&-1/4&0&5\\1/4&1&0&1/4&0&3\\-13/4&0&0&11/4&1&33\end{array}[/tex]

Now, the most negative number on the bottom row is in column 1, and the smallest quotient of column 6 and column 1 is in row 1. This makes 15/4 the "pivot". After the required row operations, the next tableau is ...

  [tex]\begin{array}{ccccc|c}1&0&4/15&-1/15&0&4/3\\0&1&-1/15&4/15&0&8/3\\0&0&13/15&38/15&1&112/3\end{array}[/tex]

All values in the last row are non-negative, so we are finished. The rightmost column tells us the values of x, y, P that are the solution to the problem

  (x, y, P) = (4/3, 8/3, 112/3)

First, I'll convert 5 1/10 into an improper fraction to make it easier to work with. I get 51/10. Then, I multiply the two fractions like so:

51/10 * 1/6 = 51/60

You multiply the numerators (the numbers on top) and the denominators (the numbers on the bottom) separately.

So the answer is 51/60.

Given the function, p(x) = 2x^2 - 1, to evaluate p(-3), you could simply substitute -3 as the input of the function.

p(-3) = 2(-3)^2 - 1

p(-3) = 2(9) - 1

p(-3) = 18 - 1

p(-3) = 17

Therefore, p(-3) = 17.

$5400 at 3.6% compounded continuously for 5 years.

Answers

Answer:

A = $6,464.97

Step-by-step explanation:

Given the principal amount of $5,400, and an interest rate of 3.6% compounded continuously for t = 5 years:

Substitute the given values into the Continuous Compounding Formula:

[tex]A = Pe^{r*t}[/tex]

where:

P = principal = $5,400

e ≈ 2.7183 (irrational number)

r = interest rate = 3.6% or 0.036

t = time in years = 5

[tex]A = Pe^{r*t}[/tex]

[tex]A = 5400e^{(0.036*5)}[/tex]

[tex]A = 5400e^{0.18}[/tex]

A = $6,464.97

Therefore, the amount after compounding continuously for 5 years is $6,464.97.
