$6,482.30

Step-by-step explanation:

150 x 40 (hours per week) = $6,000

6,890 x .07 = $482.30

6,000 + 482.30 = $6,482.30

[tex]y(x)=-\frac{3}{4}-\frac{1}{2}x-\frac{1}{2}x^2+\frac{2}{3}e^{-2x}+\frac{1}{12}e^x[/tex]

Step-by-step explanation:

[tex]y''+y'-2y=x^2,\: y(0)=0,\: y'(0)=0\\\\\mathcal{L}\{y''\}+\mathcal{L}\{y'\}-2\mathcal{L}\{y\}=\mathcal{L}\{x^2\}\\\\s^2Y(s)-sy(0)-y'(0)+sY(s)-y(0)-2Y(s)=\frac{2}{s^3}\\ \\s^2Y(s)+sY(s)-2Y(s)=\frac{2}{s^3}\\ \\(s^2+s-2)Y(s)=\frac{2}{s^3}\\ \\Y(s)=\frac{2}{s^3(s^2+s-2)}\\ \\Y(s)=\frac{2}{s^3(s+2)(s-1)}[/tex]

Perform the partial fraction decomposition

[tex]\frac{2}{s^3(s+2)(s-1)}=\frac{A}{s}+\frac{B}{s^2}+\frac{C}{s^3}+\frac{D}{s+2}+\frac{E}{s-1}\\\\2=s^2(s+2)(s-1)A+s(s+2)(s-1)B+(s+2)(s-1)C+s^3(s-1)D+s^3(s+2)E\\\\2=s^{4} A + s^{4} D + s^{4} E + s^{3} A + s^{3} B + 2 s^{3} D - s^{3} E - 2 s^{2} A + s^{2} B + s^{2} C - 2 s B + s C - 2 C\\\\2=s^{4} \left(A + D + E\right) + s^{3} \left(A + B + 2 D - E\right) + s^{2} \left(- 2 A + B + C\right) + s \left(- 2 B + C\right) - 2 C[/tex]

Solve for each constant

[tex]\begin{cases} A + D + E = 0\\A + B + 2 D - E = 0\\- 2 A + B + C = 0\\- 2 B + C = 0\\- 2 C = 2 \end{cases}[/tex]

[tex]-2C=2\\C=-1[/tex]

[tex]-2B+C=0\\-2B+(-1)=0\\-2B-1=0\\-2B=1\\B=-\frac{1}{2}[/tex]

[tex]-2A+B+C=0\\-2A+(-\frac{1}{2})+(-1)=0\\-2A-\frac{1}{2}-1=0\\-2A-\frac{3}{2}=0\\-2A=\frac{3}{2}\\ A=-\frac{3}{4}[/tex]

[tex]A+D+E=0\\-\frac{3}{4}+D+E=0\\D+E=\frac{3}{4}\\D=\frac{3}{4}-E[/tex]

[tex]A+B+2D-E=0\\-\frac{3}{4}+(-\frac{1}{2})+2(\frac{3}{4}-E)-E=0\\-\frac{3}{4}-\frac{1}{2}+\frac{3}{2}-2E-E=0\\-\frac{3}{4}+1-3E=0\\\frac{1}{4}-3E=0\\\frac{1}{4}=3E\\\frac{1}{12}=E[/tex]

Take the inverse transform and find the solution to the IVP

[tex]Y(s)=\frac{-\frac{3}{4}}{s}+\frac{-\frac{1}{2}}{s^2}+\frac{-1}{s^3}+\frac{\frac{2}{3}}{s+2}+\frac{\frac{1}{12}}{s-1}\\ \\y(x)=-\frac{3}{4}-\frac{1}{2}x-\frac{1}{2}x^2+\frac{2}{3}e^{-2x}+\frac{1}{12}e^x[/tex]

Answer:

1/4

Step-by-step explanation:

36x=32x-1

We move all terms to the left:

36x-(32x-1)=0

We get rid of parentheses

36x-32x+1=0

We add all the numbers together, and all the variables

4x+1=0

We move all terms containing x to the left, all other terms to the right

4x=-1

x=-1/4

x=-1/4

Number of distinct products that can be formed is 144

Since we need to multiply two different integers to be selected from the set which contains a total of 12 integers. This is a permutation problem since we require distinct integers.

Now, for the first integer to be selected for the product, since we have 12 integers, it is to be arranged in 1 way. So, the permutation is ¹²P₁ = 12

For the second integer, we also have 12 integers to choose from to be arranged in 1 way. So, the permutation is ¹²P₁  = 12.

So, the number of distinct products that can be formed from these two integers are ¹²P₁ × ¹²P₁ = 12 × 12 = 144

So, the number of distinct products that can be formed is 144

Answer:

500 grams is 20 percent of 2.5 kg

Step-by-step explanation:

500*100 = 50,000

50,000/2500=20

500 g is the 20% of 2.5kg.

The percentage is a ratio of number as a fraction over 100.

According to the given question

we have to find the percentage of 2.5 kg

since, 500g = [tex]\frac{500}{1000}[/tex] = 0.5kg

The percentage of a quantity x is given by

percentage = [tex]\frac{Q}{value}[/tex]×100

Substitute, Q = 0.5kg and value = 2.5kg in the above formula

⇒ percentage = [tex]\frac{0.5}{2.5}[/tex]× 100 = 20%

Hence, 500g is the 20% 0f 2.5g.

Answer:

540

Step-by-step explanation:

10% of 600 is 60, 600-60 is 540

The 10% of $600 will be $60 therefore, the net salary that Mr. Smith will take home will be $540.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

Base salary = $600

10% of $600 = (10/100) x 600 = $60

Net salary = $600 - $60 = $540

Hence "The 10% of $600 will be $60 therefore, the net salary that Mr. Smith will take home will be $540.".

Answer:

(- 21, - 13 )

Step-by-step explanation:

- 3y + x = 18 → (1)

x = 2y + 5 → (2)

substitute x = 2y + 5 into (1)

- 3y + 2y + 5 = 18

- y + 5 = 18 ( subtract 5 from both sides )

- y = 13 ( multiply both sides by - 1 )

y = 13

substitute y = - 13 into (2)

x = 2(- 13) + 5 = - 26 + 5 = - 21

solution is (- 21, - 13 )

Answer:

a. 3.4t (miles)

b. 2.125 miles

c. t = 1.6 hours

Step-by-step explanation:

A) We use this relation: Distance = time * speed ( speed or vitesse or rate)

So d= 3.4*t= 3.4t (miles)

B) If t= 5/8

then the distance d= 3.4* 5/8= 2.125 miles.

C) If the distance d= 5.44, we can find the time like:

d= 3.4*t, and we know d=5.44

so 5.44= 3.4*t or t = 5.44/3.4, t= 1.6 hours
