Answer:

You will have approximately  

4 , 049.58   in your account in 10 years

Step-by-step explanation:

To calculate the future value of $3000 deposited in an account with an 8% annual interest rate compounded monthly over 10 years, use the compound interest formula [tex]A = P(1 + r/n)^{(nt)}[/tex], resulting in approximately $6,658.93.

You want to find out how much money you will have in an account after 10 years when you deposit $3000 with an annual interest rate of 8% compounded monthly. To solve this, you can use the compound interest formula:

[tex]A = P(1 + r/n)^{nt}[/tex]

Where:

A = the future value of the investment/loan, including interest

P = the principal investment amount (initial deposit or loan amount)

r = the annual interest rate (decimal)

n = the number of times that interest is compounded per year

t = the time the money is invested or borrowed for, in years

Given the data:

P = $3000

r = 0.08 (since 8% = 0.08 when converted to a decimal)

n = 12 (monthly compounding)

t = 10 years

You can now calculate:

A = 3000(1 + 0.08/12)¹²⁰

Then:

A ≈ 3000(1 + 0.0066667)¹²⁰

A ≈ 3000(1.0066667)¹²⁰

A ≈ 3000(2.21964)

A ≈ $6,658.93

Step-by-step explanation:

x - 7 = 0 or x + 2 = 0

x = 7 or x = - 2

Answer:

  the roots are x = -2, +7

Step-by-step explanation:

The roots are the values of x that make one of the factors be zero. Whenever a factor is zero, the product is zero.

To make x+2 = 0, x = -2.

To make x-7 = 0, x = 7.

Answer:

Range of the given function is [ 5 , ∞ )

Step-by-step explanation:

Given function is [tex]y\:=\:\sqrt{x}+5[/tex]

We need to find Range of the given function.

The Range of function is the set of all possible values of the dependent variable ( here, y )  , after substituting the value of domain.

We know that square root can not have negative value. So, Domain of the given function is all non negative real number.

That is Domain = { x : x ∈ R and x ≥ 0 } = [ 0 , ∞ )

Now for range,

put x = 0 in given function,

[tex]y\:=\:\sqrt{0}+5=5[/tex]  

⇒ Minimum value of range is 5

put x = ∞ in given function,

[tex]y\:=\:\sqrt{\infinity}+5=\infinity+5=\infinity[/tex]  

⇒ Maximum value of range is ∞

Thus, Range  = { y : y ∈ R and y ≥ 5 } = [ 5 , ∞ )

Therefore, Range of the given function is [ 5 , ∞ )

Without additional context, the measure of angle 2 cannot be specific. However, the three given angles do not comprise a valid triangle. More information is required.

To find the measure of angle 2, we need to use the properties of angles formed by parallel lines and a transversal. Angle 2 is an alternate interior angle with angle 5, as they are on opposite sides of the transversal line and between the parallel lines. Therefore, angle 2 is also equal to angle 5, which measures 120°. So the measure of angle 2 is 120°.

The question didn't provide enough context or information to specifically determine the measure of angle 2. However, if we look at the three angles provided – 30°, 120°, and 60° – it's plausible that these angles might comprise a triangle since the sum of all angles in a triangle is 180° (30° + 120° + 60° = 210°, so not a valid triangle). We'd need more information to accurately determine the measure of angle 2.

Answer:

y=-3/2 x +12

Step-by-step explanation:

Solve for y.

2y+3x=24

We want 2y by itself so I will subtract 3x on both sides giving:

2y=-3x+24

Now I will divide both sides by 2 giving:

y=-3/2 x+24/2

Simplifying this gives:

y=-3/2 x+12

The slope is -3/2

The y-intercept is 12

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 2y + 3x = 24 into this form

Subtract 3x from both sides

2y = - 3x + 24 ( divide all terms by 2 )

y = - [tex]\frac{3}{2}[/tex] x + 12 ← in slope- intercept form

Answer:

[tex]m =[/tex]±[tex]\frac{7\sqrt{n}}{2n}[/tex]

Step-by-step explanation:

We have the following expression: [tex]4m^{2}n = 49[/tex] and we need to solve it for 'm'. Above the steps:

[tex]4m^{2}n = 49[/tex] ⇒ [tex]m^{2} = \frac{49}{4n}[/tex]

Taking the square rooth of both sides:

[tex]m = \sqrt{\frac{49}{4n}}[/tex] ⇒ [tex]m = \frac{7}{2\sqrt{n}}[/tex]

⇒ [tex]m =[/tex]±[tex]\frac{7\sqrt{n}}{2n}[/tex]

Answer:

7y - 3 / x  

Step-by-step explanation:

So , first you have to Simplify y/x

 ( 0 -  3/x ) +  ( 7   •    y/x )

Then simplify 3/x

 ( 0 -  3/x )  +  7y/x

Then add the fractions which have a common denominator

(Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible)

-3 + 7y/x  =  7y - 3/x  

you'll get your answer as : 7y-3 / x                        

Answer:

[tex]\frac{7y-3}{x}[/tex]

Step-by-step explanation:

Since the fractions have a common denominator of x, combine them by adding the numerators and leaving the denominator, that is

[tex]\frac{-3+7y}{x}[/tex] = [tex]\frac{7y-3}{x}[/tex]

8.54 / 8.75 =0.975

1 - 0.975 = 0.025

0.025 x 100% ( and nearest thenth)

=2.5%

Answer:

2.4%.

Step-by-step explanation:

Consider the formula for percentage change (Mathisfun)

[tex]\displaystyle \rm \text{Percentage Change} = \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}}\times 100\%[/tex].

Note that the old value shall be the one on the denominator.

For this question:

[tex]\displaystyle \rm \begin{aligned}\text{Percentage Change} &= \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}}\times 100\%\\ &= \frac{8.75 - 8.54}{8.75}\times 100\%\\&= -2.4\%\end{aligned}[/tex].

The value here is negative, but don't be alerted. A positive value of change indicates an increase, while a negative value of change indicates a decrease. In other words, the stock price dropped by 2.4%.

Answer:

Answer:

x = -5/4, y = 0

Step-by-step explanation:

Solve the following system:

{4 x + 6 y = -5 | (equation 1)

{8 x = 12 y - 10 | (equation 2)

Express the system in standard form:

{4 x + 6 y = -5 | (equation 1)

{8 x - 12 y = -10 | (equation 2)

Swap equation 1 with equation 2:

{8 x - 12 y = -10 | (equation 1)

{4 x + 6 y = -5 | (equation 2)

Subtract 1/2 × (equation 1) from equation 2:

{8 x - 12 y = -10 | (equation 1)

{0 x+12 y = 0 | (equation 2)

Divide equation 1 by 2:

{4 x - 6 y = -5 | (equation 1)

{0 x+12 y = 0 | (equation 2)

Divide equation 2 by 12:

{4 x - 6 y = -5 | (equation 1)

{0 x+y = 0 | (equation 2)

Add 6 × (equation 2) to equation 1:

{4 x+0 y = -5 | (equation 1)

{0 x+y = 0 | (equation 2)

Divide equation 1 by 4:

{x+0 y = (-5)/4 | (equation 1)

{0 x+y = 0 | (equation 2)

Collect results:

Answer:  {x = -5/4, y = 0

Answer:

The first choice, [tex]\frac{x-3}{x^{2}-4 }[/tex]

Step-by-step explanation:

Excluded value means that the value of x will make the denominator 0.

(-2)² - 4 = ?

4 - 4 = 0.

Therefore, it's the first choice– [tex]\frac{x-3}{x^{2}-4 }[/tex]

Answer:

[tex]x^2-3/x^2-4[/tex]

Step-by-step explanation:

An excluded value of x for any rational function or expression is when you have any value of x that makes the value of the function undefined. Thus, these values ​​must be excluded from the domain of the function.

in order to know if a value is an excluded value you have to calculate it in the expression:

x=-2

[tex]x^2-3/x^2-4[/tex]=[tex](-2)^2-3/(-2)^2-4[/tex]=[tex]4-3/4-4[/tex]= function undefined (because denominator 0 is undefined)

Answer: 615 ft²

Step-by-step explanation:

There are 4 walls - assume that the floor and ceiling are not being painted.

2 walls are 17 ft by 9 ft ⇒ 2(17)(9) = 306 ft²

The other 2 walls are 18 ft by 9 ft ⇒ 2(18)(9) = 324 ft²

1 window is 3.75 ft by 4 ft ⇒ 1(3.75)(4) = 15 ft²

2 walls + other 2 walls - 1 window ⇒ 306 + 324 - 15 = 615 ft²

Answer:

The total area that must be paintedis 615ft^2

Step-by-step explanation:

Here we need to calculate the total surface of the room that will be painted, this would be:

The 4 inner walls.

Minus the area of the window, that will not be painted.

I also assume that the floor and the ceiling will not be painted.

the dimensions of the room are:

17 feet long.

18 feet wide.

9 feet high.

So we will have:

two walls of 17 feet by 9 feet.

two walls of 18 feet by 9 feet.

Then the total surface of the walls is:

S = 2*(17ft*9ft) + 2*(18ft*9ft) = 630 ft^2

And the window is 3 feet 9 inches bt 4 feet.

first, we have that 1 feet = 12 inches.

then 9 inches is equivalent to:

9/12 feet = 0.75 feet.

So the area of the window is:

W = 3.75ft*4ft = 15ft^2

the difference is:

A = 630ft^2 - 15ft^2 = 615ft^2

the answer is D cuz 45+45=90 and 90+90=180

Answer:

D. [tex]45^{o}[/tex], [tex]45^{o}[/tex], [tex]90^{o}[/tex]

Step-by-step explanation:

Angles of a triangle always add u to [tex]180^{o}[/tex]. If one angle measures [tex]90^{o}[/tex], then the two remaining angles must add up to 180 - 90 = 90.

Since the two angles have equal measures, we can set up an equation:

2a = 90 (where a = angle of one equal measure)

a = 45.

Therefore, the angle measures of the triangle are [tex]45^{o}[/tex], [tex]45^{o}[/tex], [tex]90^{o}[/tex], or answer choice D.

Step-by-step explanation:

We have to assume that the third child pays a regular fee to get in.

2 adults = 2 * $4.50 =      $9.00

2 children = 2*$2.75/2=   $2.75

1 more child=1*$2.75   =   $2.75

Total                                   $14.50              

The 2 children 1/2 price is rather tricky. You could firgure out what 1/2 price is and then just double it, but that is rather long. And it will come to what I have. So let's try it

1/2 of 2.75 = 1.375

2 * 1.375 = 2.75

It is just as easy to show it rather than doing it.

the probability is 7/9

The probability that a student is a girl given that they scored an A on the test is 0.54.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

Example:

The probability of getting a head in tossing a coin.

P(H) = 1/2

We have,

We can use Bayes' theorem to find the probability that a randomly chosen girl scored an A on the test.

Let's define the following events:

A = student scored an A on the test

G = student is a girl

We want to find P(A|G), the probability that a randomly chosen girl scored an A on the test.

First, we can use the law of total probability to find the probability that a randomly chosen student scored an A:

P(A) = P(A|B) x P(B) + P(A|G) x P(G)

where B represents the event that a student is a boy.

From the problem statement, we know that 55% of the class are boys and 45% are girls, so:

P(B) = 0.55

P(G) = 0.45

We also know that 25% of the boys and 35% of the girls scored an A on the test, so:

P(A|B) = 0.25

P(A|G) = 0.35

Plugging in these values, we get:

P(A) = (0.25)(0.55) + (0.35)(0.45) = 0.29

Next, we can use Bayes' theorem to find P(A|G):

P(A|G) = P(G|A) x P(A) / P(G)

where P(G|A) is the probability that a student is a girl given that they scored an A on the test. This is what we want to find.

To find P(G|A), we can use the formula:

P(G|A) = P(A|G) x P(G) / P(A)

Plugging in the values we know, we get:

P(G|A) = (0.35)(0.45) / 0.29 = 0.54

Rounding to the nearest hundredth, we get:

P(A|G) ≈ 0.54.

Thus,

The probability that a student is a girl given that they scored an A on the test is 0.54.
