After 12 years there will be $25,865.41 in the bank account when Ann goes to college option (b) is correct.

It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.

We can calculate the compound interest using the below formula:

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

Where A = Final amount

          P = Principal amount

          r  = annual rate of interest

          n = how many times interest is compounded per year

          t = How long the money is deposited or borrowed (in years)

The formula for the compounded continuously:

[tex]\rm A = Pe^{rt}[/tex]

r = 6.4% = 0.064

t = 12

P = $12,0000

[tex]\rm A = 12,0000e^{0.064\times12}[/tex]

After solving:

A = $25,865.41

Thus, after 12 years there will be $25,865.41 in the bank account when Ann goes to college option (b) is correct.

Answer:

4.8 minutes

Step-by-step explanation:

Time = Speed * Distance

Time = 6 mi / 30 min * 24 miles=  1 mi / 5 min * 24 miles = 0,2 mi / min * 24 = 4.8 minutes

Answer:

So if you know that you can complete 6 miles over the course of 30 minutes it is just matter of multipling 30 minutes times 4, this is becasue it takes 4 times your base distance and time to get to yur goal of 24 miles.

30 x 4 equal 120

which you divide by 60 (because you have 60 minutes in one hour)

so it is safe to say that it will take 2 hours of 120 minutes to ski a ditance of 24 miles at a speed of 6 miles per 30 minutes.

School 2 students generally spend more time on volunteer work than School 1, while School 1 students tend to spend more time than School 3.

Based on the dot plots representing the number of hours spent on volunteer work by students from three different high schools, we can draw some conclusions about the median values of the data sets.

Firstly, comparing School 1 and School 2, it appears that students in School 2 generally spend more time doing volunteer work. This conclusion is supported by the higher frequency of dots in the higher hour range in School 2 compared to School 1.

Next, comparing School 1 and School 3, it seems that students in School 1 generally spend more time on volunteer work. The dot plot for School 1 shows a higher frequency of dots in the higher hour range compared to School 3.

In summary, students in School 2 generally spend more time doing volunteer work than those in School 1, while students in School 1 tend to spend more time on volunteer work than those in School 3.

Step-by-step explanation:

Since the triangle is right use Pythagoras' identity to solve for x

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

The hypotenuse is the side opposite the right angle, thus

x² + 1² = ([tex]\sqrt{2}[/tex])²

x² + 1 = 2 ( subtract 1 from both sides )

x² = 1 ( take the square root of both sides )

V = πr2h

V = π(4)2(7)

V = π(16)(7)

V = 112π

V = 351.858

Final answer:

The volume of the cylindrical container is approximately 352.6 cubic inches.

Explanation:

To find the volume of a cylindrical container, you can use the formula V = πr²h, where V is the volume, r is the radius, and h is the height. In this case, the radius is 4 inches and the height is 7 inches. Plug these values into the formula:

V = 3.14 x (4 inches)² x 7 inches = 3.14 x 16 square inches x 7 inches = 352.64 cubic inches.

Since the question asks for the volume rounded to the nearest tenth, the answer is approximately 352.6 cubic inches.

ANSWER

(–5, –11), because the point satisfies both equations

EXPLANATION

The given equations are:

Line A: y = x – 6

Line B: y = 3x + 4

We substitute (-5,-11) into both equations.

Line A: -11 = -5– 6

This implies that,

-11=-11

This statement is true.

Line B: -11= 3(-5)+ 4

-11= -15+ 4

-11=-11

This is also true.

Since this point ,(&6,-11) satisfy both equations, it is their solution.

The bus can hold no more than 40 people. 6 are already on so at most, there can be 34 others on board. But the number doesn’t have to be exact.

Answer:

Step-by-step explanation:

Let's start by simplifying a little:

g(x) = -2[(x − 1)² + 3]

g(x) = -2(x − 1)² - 6

The negative sign in front means a reflection about the x axis.  The 2 coefficient means a vertical stretch by a factor of 2.  The x−1 means a horizontal shift to the right by 1 unit.  And the -6 means a vertical shift down six units.

So the answer is the third one.

Answer:

Final answer:

To find what multiplied by 3/4 equals 1/4, set up the equation 3/4 * x = 1/4 and solve for x, giving the answer x = 1/3.

Explanation:

This question demands basic understanding of multiplication and reciprocals.

The question asks, "3/4 times what equals 1/4?". To find the answer, we can set up the equation 3/4 * x = 1/4, where x is the unknown we are trying to find. Solving for x involves dividing both sides of the equation by 3/4 to isolate x.

Therefore, the equation simplifies to x = (1/4) / (3/4). Performing the division gives us x = 1/3. This means that 1/3 is the number you need to multiply by 3/4 to get 1/4.

To find what number multiplied by 3/4 equals 1/4, divide 1/4 by 3/4, which is the same as 1/4 times the reciprocal of 3/4 (4/3), resulting in 1/3.

To find out 3/4 times what equals 1/4, we are essentially looking for a number that when multiplied by 3/4 gives us 1/4. The mathematical operation we need to use is division since we want to find what 1/4 divided by 3/4 is. So, the equation we are solving is (1/4) ÷ (3/4).

When we divide fractions, we multiply by the reciprocal of the divisor. The reciprocal of 3/4 is 4/3. So, the calculation now is (1/4) × (4/3).

Multiplying the numerators and denominators separately, we get (1 × 4) / (4 × 3) which simplifies to 4/12. After simplification, 4/12 reduces to 1/3. Therefore, 3/4 times 1/3 equals 1/4.

EXPLANATION

The numbers are given in standard form.

The first criteria we will use to order them is the exponents.

The bigger the exponents the bigger the number.

The second criteria is that, if the exponents of any two numbers are the same, then we use the numbers multiplying the powers of 10 to order.

[tex]9.4 * 10^{-8} \: < \: 9.25 * 10^{-6} \: < \: 2.5 * 10^3 \: < \: 7* 10^3[/tex]

The correct choice is A.

Answer:

Option A. [tex]9.4\times 10^{-8}< 9.25\times 10^{-6}< 2.5\times 10^{3}<7\times 10^{3}[/tex]

Step-by-step explanation:

The given numbers are [tex]9.4\times 10^{-8}, 9.25\times 10^{-6}, 2.5\times 10^{3},7\times 10^{3}[/tex].

These are numbers written in scientific notation.

To identify the order of the numbers from least to greatest we will convert the numbers into the standard from.

[tex]9.4\times 10^{-8}[/tex] = 0.000000094

[tex]9.25\times 10^{-6}[/tex] = 0.00000925

[tex]2.5\times 10^{3}[/tex] = 2500

[tex]7\times 10^{3}[/tex] = 7000

Now we can arrange then from least to greatest.

0.000000094 < 0.00000925 < 2500 < 7000

OR

[tex]9.4\times 10^{-8}< 9.25\times 10^{-6}< 2.5\times 10^{3}<7\times 10^{3}[/tex]

The answer is the 1st [tex]\frac{\left[\begin{array}{cc}16&3\\8&1\end{array}\right]}{-8}=1[/tex]

Step-by-step explanation:

Lets revise the Cramer's rule

- If the system of equation is ax + by = c and dx + ey = f

- A is the matrix represent this system of equation

- The first column has the coefficients of x, and

  the second column has the coefficients of y

∴ A = [tex]\left[\begin{array}{cc}a&b\\d&e\end{array}\right][/tex]

- Ax means replace the column of x by the answers of the equation

∴ Ax = [tex]\left[\begin{array}{ccc}c&b\\f&e\end{array}\right][/tex]

- Ay means replace the column of y by the answers of the equation

∴ Ay = [tex]\left[\begin{array}{ccc}a&c\\d&f\end{array}\right][/tex]

- x = Dx/D, where Dx is the determinant of Ax and D is the determinant

 of A

- The determinant of A = ae - bd

- The determinant of Ax = ce - bf

* Now lets solve the problem

∵ x + 3y = 16 and 3x + y = 8

∴ A = [tex]\left[\begin{array}{cc}1&3\\3&1\end{array}\right][/tex]

- Replace the column of x by the answer to get Ax

∴ Ax = [tex]\left[\begin{array}{cc}16&3\\8&1\end{array}\right][/tex]

∵ [tex]x=\frac{Dx}{D}[/tex]

∵ Dx = [tex]\left[\begin{array}{cc}16&3\\8&1\end{array}\right]=(16)(1)-(3)(8)=16-24=-8[/tex]

∵ D = [tex]\left[\begin{array}{cc}1&3\\3&1\end{array}\right]=(1)(1)-(3)(3)=1-9=-8[/tex]

∴ x = [tex]\frac{\left[\begin{array}{cc}16&3\\8&1\end{array}\right]}{-8}=\frac{-8}{-8}=1[/tex]

* x = [tex]\frac{\left[\begin{array}{cc}16&3\\8&1\end{array}\right]}{-8}=1[/tex]

Answer:

x=3; x=-3; x=√5; x=-√5

Step-by-step explanation:

The equation can be simplified by treating (x^2 - 2) as y. Solving the quadratic equation for y results in y = 4 and y = 7. By substituting these back into the equation and solving for x, we find x = ±sqrt(6) and x = ±sqrt(9). Therefore, one possible solution for x is sqrt(6).

The equation provided is a quadratic in the form of x. In this case, let's take: (x^2 - 2) = y. Therefore the equation can be rewritten as: y^2 - 10y + 21 = 0. In order to find the roots of the equation, we should use the quadratic formula: y = [10 ± sqrt((10)^2 - 4*1*21)] / (2*1), which gives us y = 4 and y = 7. Now we substitute back y = (x^2 - 2). This will form two more quadratic equations: x^2 - 2 = 4 and x^2 - 2 = 7. Solving these, we get x = ±sqrt(6) and x = ±sqrt(9). So, one value of x that is a solution to the equation could be sqrt(6).

3 and 9 can't be written in cubic form unless we use radical numbers.

So the only choice left is D)

D) [tex]x^3+8y^6[/tex]

The only option that matches with the sum of cubes form is the last option,

D) [tex]x^{3}+8y^{6}[/tex]

and it can be rewritten as the following expression:

[tex]x^{3}+8y^{6}=x^{3}+(2y^{2})^{3}\\\\x^{3}+(2y^{2})^{3}=(x+2y^{2})(x^{2}-2xy^{2}+(2y^{2})^{2})\\\\(x+2y^{2})(x^{2}-2xy^{2}+(2y^{2})^{2})=(x+2y^{2})(x^{2}-2xy^{2}+4y^{4})\\\\(x+2y^{2})(x^{2}-xy^{2}+4y^{4})=x*x^{2}-2x^{2}y^{2}+2xy^{4}+2x^{2}y^{2}-2xy^{4}+8y^{6}\\\\x*x^{2}-2x^{2}y^{2}+2xy^{4}+2x^{2}y^{2}-2xy^{4}+8y^{6}=x^{3}+8y^{6}[/tex]

Answer: 68 total outcomes

Final answer:

To find the total number of outcomes, we multiply the number of options for each class type using the fundamental counting principle, resulting in 5 × 4 × 5 × 3 = 300 total outcomes.

Explanation:

The question asks us to find the total number of outcomes for first-year students at a school who must choose one each of 5 English classes, 4 history classes, 5 math classes, and 3 physical education classes. To calculate the total number of outcomes, we use the fundamental counting principle, which states that if there are m ways to do one thing, and n ways to do another, then there are m × n ways of doing both.

In this scenario, the student can choose:

5 English classes

4 history classes

5 math classes

3 physical education classes

Applying the fundamental counting principle, we multiply the number of options for each subject:

5 (English) × 4 (History) × 5 (Math) × 3 (Physical Education) = 300 total outcomes.
