Answer:

36

Step-by-step explanation:

2x + 8 = 20

2x = 20 - 8

2x = 12

x = [tex]\frac{12}{2}[/tex]

x= 6

6x

6(6) = 36

Answer:

43.2 years

Step-by-step explanation:

The formula for continuously compounded interest on a principal investment Pat a given interest rater

over time tin years is given by A = Pe^rt

P = Initial amount compounded = $12000

A = Amount compounded continuously after t years = six times it's original worth

= 6 × $12,000 = $72000

r = Interest rate = 4.15%

t = time in years = ?

Making t the subject of the formula

t = ln(A/P) / r

First, convert R percent to r a decimal

r = R/100

r = 4.15%/100

r = 0.0415 per year,

Then, solve our equation for t

t = ln(A/P) / r

t = ln(72,000.00/12,000.00) / 0.0415

t = 43.175 years

Approximately t = 43.2 years

The time required to get a total amount of $ 72,000.00 from compound interest on a principal of $ 12,000.00 at an interest rate of 4.15% per year and compounded continuously is 43.2years.

Answer:

$1954

Step-by-step explanation:

Given the profit function expressed as;

y=-3x^2 + 197x – 1279

The profit is at maximum when dy/dx = 0

dy/dx = -6x + 197

0 = -6x+197

6x = 197

x = 197/6

x = 32.83

substitute 32.83 into the modeled function

y=-3x^2 + 197x – 1279

y -3(32.83)²+197(32.83) - 1279

y = -3(1,078.03)+6,467.51 - 1279

y = -3,234.09+6,467.51-1279

y = 1,954.42

hence the maximum amount of profit the company can make, to the nearest dollar is $1954

Answer:

[tex]y = \frac{1}{2} x + \frac{1}{2} [/tex]

Step-by-step explanation:

equation of line formula:

[tex]y = mx + c[/tex]

m = slope

c = y-intercept

1) find m

slope formula:

[tex]m = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1}} [/tex]

take 2 coordinates from the given graph and substitute the values into the slope formula

i) (-1,0)

[tex]x _{1} = - 1[/tex]

[tex]y_{1} = 0[/tex]

ii) (3,2)

[tex]x_{2} = 3[/tex]

[tex]y_{2} = 2[/tex]

substitute the values into the slope formula

[tex]m = \frac{2 - 0}{3 - ( - 1)} [/tex]

[tex]m = \frac{2}{4} [/tex]

[tex]m = \frac{1}{2} [/tex]

2) find the half equation of the line by substituting the value of m into the equation of line formula

[tex]y = \frac{1}{2} x + c[/tex]

3) find c by substituting either coordinate into the half equation

(3,2)

x = 3

y = 2

[tex]2 = \frac{1}{2} (3) + c[/tex]

[tex]2 = \frac{3}{2} + c[/tex]

[tex]2 - \frac{3}{2} = c[/tex]

[tex] \frac{1}{2} = c [/tex]

[tex]c = \frac{1}{2} [/tex]

4) find equation of line by substituting the value of c into the half equation

[tex]y = \frac{1}{2} x + \frac{1}{2} [/tex]

Answer:

( x , y ) = ( -1,1/2)

Step-by-step explanation:

Solve the equation for X

[tex]\left \{ {{x=-5/3+4/3y} \atop {5x+8y=-1}} \right.[/tex]

Substitute the given value of x into the equation 5x + 8y = -1

5(-5/3+4/3y)+8y=-1

Solve the equation for Y

y=-1/2

Substitute the given value of y into the equation x = -5 / 3 + 4 / 3y

x=-5/3+4/3×1/2

Solve the equation for X

x=-1

The system solution is the computer pair

(x,y)=(-1,1/2)

Check if the ordered pair given to the solution of the system of equations

[tex]\left \{ {{3*(-1)-4*1/2=-5} \atop {5*(-1)+8*1/2=-1}} \right.[/tex]

Simplify the equations

[tex]\left \{ {{-5=-5} \atop {-1=-1}} \right.[/tex]

The ordered pair is the solution of the system of equations, since both equations are true

(x,y)=(-1,1/2)

Answer:

The amount is $2137.24 and the interest is $237.24.

Step-by-step explanation:

STEP 1: To find amount we use formula:

A = P[tex](1+\frac{x}{y} )nt[/tex]

A = total amount P = principal or amount of money deposited, r = annual interest rate n

= number of times compounded per year t = time in years In this example we have

P = $1900 , r = 4% , n = 1 and t = 3 years

After plugging the given information we have

A = 1900 [tex](1+\frac{0.04}{1})^{1*3}[/tex]

A = 1900 · 1.0[tex]4^{3}[/tex]

A = 1900 · 1.124864

A = 2137.24

STEP 2: To find interest we use formula A = P + I, since A = $2137.24 and P = $1900 we

have:

A = P + I

2137.24 = 1900 + I

I = 2137.24 − 1900

I = 237.24

Answer:

Width=9.5, Length=32.5

Step-by-step explanation:

Let x be the width of the rectangle,

The length is 4 feet more than 3 times the width,

The length= 3x+4

The perimeter is

2(x)+2(3x+4)=84

2x+6x+8=84

8x=76

x=76/8

x=9.5

The Width=9.5

Length= 3(9.5)+4=32.5

What is this question do you need help or you are playing

Answer:

1/5

Step-by-step explanation:

There are 2 out of 10 that are blue so in fraction form thats 2/10 so when you simplify it, the simplest form is 1/5

Well, as it says, your first statement needs to explain what interests you about the program.

If you feel you need multiple paragraphs, let the first be an introduction, around 4 or 5 sentences. Include, possibly what pushed you to apply for this program, what you're looking forward to, and a reason for them to hire you. You can add a thesis statement of sorts if that helps (a short statement, usually one sentence, that summarizes the main point or claim of a paper). The first paragraph can be short, it doesn't need to be too in-depth. You can talk more about that later in your statement.

The body paragraphs must include your goals and extracurricular interests (what courses would you like to take and why?).

As it states, you must list your GPA, what interests you about the Major and/or Minor/Workshop courses, and what you can contribute (you can build off of what you said in your first paragraph here).

It is very important to share additional details you think are important, such as accomplishments you are proud of, for example.

A conclusion would be nice, a short and sweet wrap-up of your overall statement (not too long).

Remember, the name of the game is to sound confident and prove to them that you are in fact a good fit for the program! Good luck! Stay focused ^^

When looking at the following expression, we can tell that it has no rational roots. However, it does have zeros at:

t = -0.45, 2.16, 12.29.

When thinking of the cubic curves you know that p(t) < 0 for 2.16 < t < 12.29. Meaning the team took a loss in years 3-12.

Please consider me brainliest.

Answer:

Step-by-step explanation:

4x-2 +3x+7 = 180

7x + 5 = 180

7x = 175

x = 25

3(25) + 7 = 82

Answer:

82 (degrees)

Step-by-step explanation:

4x-2+3x+7=180=7x+5...175=7x...x=175/7... x=25

This is both angles combined which we know adds up to half of the entire quadrilateral (180 degrees). Then solve.

3(25) +7=82 which is equal to f

f=82
