15 × 6/100=0.9

15+0.9=$15.9

Answer: $15.90

Step-by-step explanation:

15*0.06=.90 +15=15.90

In order to solve this problem, you need to first change 6% to a decimal. 6 divided by 100 is 0.06. Then, you need to multiply that by 15 to figure out the amount in tax. Finally, you need to add 15 dollars with 90 cents to get $15.90

Answer:

vertex = (3, - 8 )

Step-by-step explanation:

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

\(x_{vertex}\) = - \(\frac{b}{2a}\)

y = x² - 6x + 1 ← is in standard form

with a = 1 and b = - 6 , thus

\(x_{vertex}\) = - \(\frac{-6}{2}\) = 3

Substitute x = 3 into the function for y

y = 3² - 6(3) + 1 = 9 - 18 + 1 = - 8

vertex = (3, - 8 )

Step-by-step explanation:

To solve the equation \(6sin^2(x)\) + 6sin(x) + 1 = 0, we can use algebraic methods and the unit circle to determine the values of x that satisfy the equation.

1. Start by rearranging the equation to a quadratic form: \(6sin^2(x)\) + 6sin(x) + 1 = 0.

2. Notice that the equation resembles a quadratic equation in terms of sin(x). Let's substitute sin(x) with a variable, such as u: \(6u^2\) + 6u + 1 = 0.

3. Solve this quadratic equation for u. You can use the quadratic formula or factorization methods to find the values of u. The solutions are u = (-3 ± √3) / 6.

4. Since sin(x) = u, substitute back the values of u into sin(x) to obtain the values for sin(x): sin(x) = (-3 ± √3) / 6.

5. To find the values of x, we can use the inverse sine function. Take the inverse sine of both sides: x = arcsin[(-3 ± √3) / 6].

6. The arcsin function has a range of [-π/2, π/2], so the values of x lie within that range. Use a calculator to find the approximate values of x based on the values obtained in step 5.

7. Plot the obtained x-values on the graph to show the solutions of the equation \(6sin^2(x)\) + 6sin(x) + 1 = 0. The graph will illustrate the points where the curve intersects the x-axis.

The following can be shown about the diagonals of parallelogram PQRS to compare the proof that diagonals of a parallelogram bisect each other: B. PR and SQ have the same midpoint.

In Mathematics and Geometry, a parallelogram is a geometrical figure (shape) and it can be defined as a type of quadrilateral and two-dimensional geometrical figure that has two (2) equal and parallel opposite sides.

In order for any quadrilateral to be considered as a parallelogram, two pairs of its parallel opposite sides must be equal (congruent). This ultimately implies that, the diagonals of a parallelogram would bisect one another only when their midpoints are the same:

(Line segment PR)/2 = (Line segment SQ)/2

Line segment PR = Line segment SQ

Answer:

\((- \infty, 2), (2, \infty)\)

Step-by-step explanation:

Given the function:

\(f(x) = \dfrac{x+1}{x-2}\)

To find:

Domain of the function.

Solution:

First of all, let us learn about definition of  domain of a function.

Domain of a function is the valid input values that can be provided to the function for which output is defined.

OR

Domain of a function \(f(x)\) are the values of \(x\) for which the output \(f(x)\) is a valid value.

i.e. The function does not tend to \(\infty\) or does not have \(\frac{0}0\) form.

So, we will check for the values of \(x\) for which \(f(x)\) is not defined.

For value to tend to \(\infty\), denominator will be 0.

\(x-2\neq 0 \\\Rightarrow x \neq 2\)

So, the domain can not have x = 2

Any other value of x does not have any undefined value for the function \(f(x)\).

Hence, the answer is:

\(\bold{(- \infty, 2), (2, \infty)}\)     [2 is not included in the domain].

the statement that "you walk at a constant rate" tells us that the relationship is indeed proportional, namely, there's a value in the input that's consistent or common yielding the output.

Check the picture below.

to get the equation of any straight line, we simply need two points off of it, for the distance "from school" table, let's use those two points in that table

\((\stackrel{x_1}{10}~,~\stackrel{y_1}{0.5})\qquad (\stackrel{x_2}{30}~,~\stackrel{y_2}{1.5}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{\textit{\large rise}} {\stackrel{y_2}{1.5}-\stackrel{y1}{0.5}}}{\underset{\textit{\large run}} {\underset{x_2}{30}-\underset{x_1}{10}}}\implies \cfrac{1}{20}\)

\(\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{0.5}=\stackrel{m}{\cfrac{1}{20}}(x-\stackrel{x_1}{10})\implies y-0.5=\cfrac{1}{20}x-\cfrac{1}{2} \\\\\\ y=\cfrac{1}{20}x-\cfrac{1}{2}+0.5\implies y=\cfrac{1}{20}x-\cfrac{1}{2}+\cfrac{1}{2}\implies \boxed{y=\cfrac{1}{20}x}\)

To convert square meters to square centimeters, we need to multiply by the conversion factor (100 cm / 1 m)^2.

So,

3.9 m² = 3.9 × (100 cm / 1 m)²

3.9 m² = 3.9 × 10,000 cm²

3.9 m² = 39,000 cm²

Therefore, 3.9 square meters is equal to 39,000 square centimeters.

Step-by-step explanation:

The average EMF induced in the coil is 2.714336 × 10⁻⁴

To calculate the average EMF induced in the coil, we need to determine the change in magnetic flux through the coil and divide it by the time interval over which the change occurs.

The magnetic flux (Φ) through a coil is given by the formula:

Φ = B * A * cos(θ),

where B is the magnetic field strength, A is the area of the coil, and θ is the angle between the magnetic field and the normal to the coil.

When the coil is perpendicular to the field at t = 0, the angle θ is 90 degrees, and the magnetic flux is:

Φ1 = B * A * cos(90) = 0,

since the cosine of 90 degrees is zero.

At t = 0.015s, the coil becomes parallel to the field, so the angle θ becomes 0 degrees. The magnetic flux at this moment is:

Φ2 = B * A * cos(0) = B * A.

The change in magnetic flux (ΔΦ) during this transition is given by:

ΔΦ = Φ2 - Φ1 = B * A.

To find the average emf (ε) induced in the coil, we divide the change in magnetic flux by the time interval (Δt) over which the change occurs:

ε = ΔΦ / Δt.

Given that the radius of the coil is 6.0 cm, the area (A) of the coil can be calculated using the formula for the area of a circle:

A = π * r²

where r is the radius of the coil. Substituting the values, we get:

A = π * (0.06 m)²

Substituting the values of B and A, and noting that the time interval Δt is 0.015s, we can calculate the average EMF induced in the coil:

ε = (B * A) / Δt.

By substituting the known values, the calculation becomes:

ε = (3.6x10⁻⁴ T) * (π * (0.06 m)²) / 0.015 s. =  2.714336 × 10⁻⁴

It will take approximately 3.96 years (or approximately 3 years and 11 months) for Vincent's savings to reach $9,000.

To solve this problem, we can use the formula for the future value of an ordinary annuity:

FV = P * [(1 + r)^n - 1] / r

Where:

FV = Future Value

P = Payment (deposit amount)

r = Interest rate per compounding period

n = Number of compounding periods

In this case, Vincent deposits $165 at the end of each quarter, so P = $165. The annual interest rate is 6%, compounded quarterly, so the interest rate per compounding period, r, would be 6% divided by 4 (since there are 4 quarters in a year), which is 0.06/4 = 0.015.

We want to find the number of years, n, it will take for Vincent's savings to reach $9,000. Let's substitute the given values into the formula and solve for n:

9,000 = 165 * [(1 + 0.015)^n - 1] / 0.015

To solve this equation, we can use algebraic techniques or a financial calculator. Solving the equation, we find that n is approximately 15.83.

Since n represents the number of quarters, we need to convert it to years by dividing it by 4 (since there are 4 quarters in a year):

n (in years) = 15.83 / 4 ≈ 3.96

Therefore, it will take approximately 3.96 years (or approximately 3 years and 11 months) for Vincent's savings to reach $9,000.

\(\large \boxed{\sf x=9 \ \ \ or \ \ \ x=-3 }\)

Step-by-step explanation:

We are looking for the value of x that satifies the following equation :

\(\sf x^2 -6x -20 =7\)

Le'ts substract 7 from both sides :

\(\sf x^2 -6x -27 =0\)

This equation is a quadratic equation in the form ax²+bx+c=0

The solution of this equation is given by the quadratic formula :

\(\sf x=\dfrac{-b\pm\sqrt{\Delta}}{2a}\)

Where \(\sf \Delta = b^2-4ac\) is the discriminant.

There are 3 cases depending on the values of the discriminant :

Let's calculate the discriminant :

\(\sf \Delta = (-6)^2-4\times1\times(-27)\\\Delta = 36+108\\\underline{\sf \Delta = 144 > 0}\)

There are 2 real roots.

Now let's use the quadratic formula to find the two roots.

\(\sf x=\dfrac{-(-6)\pm \sqrt{144}}{2\times1} \\x=\dfrac{6\pm12}{2} \\\boxed{\sf x=9 \ \ \ or \ \ \ x=-3 }\)
