Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a ≤ b.

a is bigger or equal value of an is indicated by the notation a ≥ b.

Let,The no. of tapes be 'x' and the no. of CD be 'y'.

[tex]5x = 200[/tex]

[tex]x = 40[/tex]

x as his total income

x = 12(25 000) + 0.065(100 000)

x = 300 000 + 6 500

x = 306 500

12(25 000) = 300 000 (12 months salary)

0.065(100 000) = 6 500 (bonus)

Therefore, the salesman total income is 306 500 in 2014.

Step-by-step explanation:

The lowest term of 38/46 can be expressed as a decimal as 0.826087 and percentage as 82.6087%.

The fraction 38/46 is equivalent to 19/23.

Once the absolute value of the top number, or numerator, (38) is less than the absolute value of the bottom number, or denominator, the fraction is considered to be correct (46).

The fraction 38/46 can be reduced.

To make things simpler, we'll employ the Greatest Common Factor (GCF) technique.

The GCF is the largest number equally divisible by two or more other numbers.

The numerator and denominator factors are listed, and the greatest number repeated in both lists is used to calculate the GCF:

The factors of 38 exists 1,2,19,38;

The factors of 46 exists 1,2,23,46.

We can see that the GCD is 2 because it is the largest number by which 38 y 46 can be divided without leaving any residue.

Simply divide the numerator and denominator by 2 to lower this fraction (the GCF).

So, [tex]$\frac{38}{46}=\frac{38 \div 2}{46 \div 2}=\frac{19}{23}$[/tex]

Therefore, 38/46 exists equivalent to 19/23 in the reduced form.

The factors exists numbers that multiply each other to get another number.

The fraction 38/46 exists even equivalent to 38÷46 and can also be expressed as a decimal as 0.826087 and expressed as a percentage as 82.6087%.

Vertically opposing angles are established when two lines intersect at a single place and the angles opposite to each other are created using the two intersecting lines. There is never a difference between these angles.

Those angles are referred to as vertical angles if they share an arm and a vertex. Additionally, the nearby angles are those that are produced side by side. The primary characteristic of these angles is that they never cross over.

The time on clock shows at the instant you see the clock at the origin showing 3.80 μs is 5.47 × [tex]10^{-6[/tex] s.

As per the given data the values of x and y are as follows:

x = 300 m

y = 400 m

Here you are standing at the point (300, 400) in a reference frame with synchronized clocks.

Here we have to determine the time on clock shows at the instant you see the clock at the origin showing 3.80 μs.

The point where you're standing (300, 400) is 500 m from the origin.

Therefore my distance from the origin is 500 m

Speed of light , c = 3 × [tex]10^8[/tex] m/s

The clock at the origin showing, [tex]T_0[/tex] = 3.80 μs

[tex]T_0 = 3.8 \times 10^{-6}[/tex] s

Time shown by my clock , T = distance ÷ c + [tex]T_0[/tex]

T = [tex]\frac{500}{(3 \times 10^8)} + 3.8 \times 10^{-6[/tex]

The remainder when f(x) = 3x³ + 24x² − 45x − 162 is divided by (x + 8) is 198.  

A polynomial is defined as an expression which is composed of variables, constants and exponents, that are combined using mathematical operations such as addition, subtraction, multiplication and division.

Therefore, the remainder when f(x) = 3x³ + 24x² - 45x - 162 is divided by (x + 8) is as follows:

The dividend is x + 8.

Hence, let's Set the dividend to 0

x + 8 = 0

x = -8

Substitute x = - 8 in f(x) = 3x³ + 24x² - 45x - 162

f(-8) = 3(-8)³ + 24(-8)² - 45(-8) - 162

f(-8) = - 1536 + 1536 + 360 - 162

Answer:

y = -0.11x + 0.89

Step-by-step explanation:

First find the slope of the tangent line, which is equal to dy/dx

Find the derivative of y at 1:

dy = cos(t) + 2cos(2t)

dy = cos(1) + 2cos(2)

dy = -0.292

Then the derivative of x at -1:

dx = -sin(t) - 2sin(2t)

dx = -sin(-1) - 2sin(-2)

dx = 2.66

So now calculate dy/dx:

dy/dx = -0.11

Now use point slope form to find the equation of the tangent line:

y - 1 = -0.11(x + 1)

y - 1 = -0.11x - 0.11

y = -0.11x + 0.89

Answer: The measures of the angles in triangle ABC are BAC = 68°, BCA = 50.6°, and ABC = 61.4°. The lengths of the sides are AB = 12, AC = 14, and BC = 13.68.

Step-by-step explanation:

To find the angles and sides of a triangle, you need to know at least three pieces of information about the triangle. In this case, you are given the lengths of sides AB and AC, and the measure of angle BAC.

You can use the Law of Sines to find the measure of the third angle and the length of the third side. The Law of Sines states that for any triangle, the ratio of the length of a side to the sine of the angle opposite that side is the same for all sides and angles in the triangle. In other words, if we let a, b, and c represent the lengths of the sides of the triangle and A, B, and C represent the measures of the angles opposite those sides, then the following equation holds:

a/sin A = b/sin B = c/sin C

In triangle ABC, we are given the lengths of sides AB and AC and the measure of angle BAC. We can use the Law of Sines to find the measure of angle BCA and the length of side BC.

First, we can find the measure of angle BCA using the equation:

a/sin A = b/sin B = c/sin C

Substituting the known values, we get:

14/sin BAC = 12/sin BCA

Solving for sin BCA, we get:

sin BCA = 14/12 * sin BAC

Plugging in the given value for sin BAC, we get:

sin BCA = 14/12 * sin 68°

Using a calculator, we find that sin 68° = 0.906308

So sin BCA = 0.763696

To find the measure of angle BCA, we can use the inverse sine function on our calculator. The inverse sine of 0.763696 is about 50.6°.

Now that we know the measures of angles BAC and BCA, we can use the fact that the angles in a triangle sum to 180° to find the measure of angle ABC:

BAC + BCA + ABC = 180°

Substituting the known values, we get:

68° + 50.6° + ABC = 180°

Solving for ABC, we get:

ABC = 180° - 68° - 50.6°

This simplifies to:

ABC = 61.4°

Now that we have found the measures of all three angles, we can use the Law of Sines again to find the length of side BC.

We can use the equation:

a/sin A = b/sin B = c/sin C

Substituting the known values, we get:

14/sin BAC = 12/sin BCA = BC/sin ABC

Solving for BC, we get:

BC = 14/sin BAC * sin ABC

Plugging in the values we found earlier, we get:

BC = 14/0.906308 * sin 61.4°

Using a calculator, we find that sin 61.4° = 0.875

So BC = 14/0.906308 * 0.875 = 13.68

The measures of the angles in triangle ABC are BAC = 68°, BCA = 50.6°, and ABC = 61.4°. The lengths of the sides are AB = 12, AC = 14, and BC = 13.68.

Answer:

Subtotal: $250.00

Savings: $62.50

New Subtotal: $187.50

Total: $195.00

Step-by-step explanation: First, multiply 25 by 10. You'd get 250. Then, recall the formula to find the worth after a percent is applied:

Worth = Whole number * part percent / 100

Plug in the numbers:

Worth = 250 * 25 / 100

6250 / 100

=  62.50

Now, since it's a discount we need to subtract the discount price from the current subtotal. This would look like this:

250 - 62.50 = 187.50

Now, use the same formula to find the sales tax:

187.50 * 4 /100

750 / 100

= 7.5

So, since we need to pay the tax, we add the amount to our current subtotal:

187.50 + 7.5 = 195

So, our total is $195.00

A parabola is a graph of a quadratic equation of the form

In order to write the equation of a parabola in vertex form, we need to first determine the values of a, b, and c.

To find the vertex of the parabola, we know that the vertex lies at the point (0,0), so the x-coordinate of the vertex is 0. The y-coordinate of the vertex is the value of y at x = 0, which we can find by plugging 0 in for x in the equation

So the vertex of the parabola is (0, c).

Since the parabola passes through the point (6,9), we can plug in these values for x and y into the equation y = ax^2 + bx + c to find the values of a, b, and c. We get the equation

We can now write the equation of the parabola in vertex form. In vertex form, the equation of a parabola is y = a(x - h)^2 + k, where (h,k) is the vertex of the parabola. In our case, the vertex is (0,c), so we can write the equation as y = a(x - 0)^2 + c. Plugging in the values we found earlier, we get

Finally, we can simplify the equation by dividing both sides by 36a. This gives us
