Answer:

1. Sine (sin) 2. Cosine (cos) 3. Tangent (tan) 4. Secant (sec) 5. Cosecant (csc) 6. Cotangent (cot) These functions are used to relate the angles of a triangle with the sides of that triangle.

Step-by-step explanation:

Sine and cosine functions are examples of trigonometric functions that generate periodic waves. These waves can be represented in equations like y = A sin(wt + p) and x(t) = A cos(wt + p), where A is the amplitude, w is the angular frequency, t is the time, and p is the phase shift.

Trigonometric functions like the sine, cosine, and tangent functions are often used to generate periodic waves in mathematics and physics. For instance, simple harmonic motion, which is related to alternating cycles in physics, can be represented by sine and cosine functions.

Let's consider the example of a bouncing object on a spring. The object's position over time can be represented by a sine function, resulting in a wave-like pattern on a graph. A sine function generating a periodic wave would look like this: y = A sin(wt + p), where A is the amplitude, w is the angular frequency, t is the time, and p is the phase shift.

Another example is a cosine function that might represent a phase-shifted wave, like this: x(t) = A cos(wt + p). Again, A is the amplitude, w is the angular frequency, t is the time, and p is the phase shift. This function is effectively identical to the sine function but is shifted to the right on the x-axis.

Answer:

145

Step-by-step explanation:

The volume of the rectangular prism bin is area of base * height.

Base/top is a square, so area would be 150 * 150 = 22,500

Thus, volume of bin = 22,500 * 210 = 4,725,000

Using volume of sphere formula and given radius of each ball is 16cm, we can say that

Volume of 1 Ball = [tex]\frac{4}{3}\pi r^3 = \frac{4}{3}\pi (16)^3=17,157.28[/tex]

Since, 190% is including the packing, we can take volume of 1 ball (inclusive of packaging) to be  1.9 * 17,157.28 = 32,598.83

How many of this will fit in the bin, we divide bin volume by this:

Number of Balls = [tex]\frac{4,725,000}{32,598.83}=144.94[/tex]

Rounding, we can say that we can fit 145 balls, 2nd answer choice is right.

The answer would be B. The highest price and the lowest price of the game differ by less than $14. Hope this helps!

B. The highest price and the lowest price of the game differ by less than $14.

Given is that the the price of Song Hero showed greater variability. This means their prices are more varied in range.

If Song Hero was priced between $35 and $49 during the 10-month period, This means the variability of Star chasers is less than [tex]49-35=$14[/tex]

Since, $14 is Song Hero’s range, the range for Star chasers should be less.

Therefore, option B is correct.

Answer:

1. D ∠4 and ∠5

2. C 37°

3. A 50°

Step-by-step explanation:

1. Complementary angles are those that add up to 90°.

From the diagram you can see that angles 4 and 5 together form right angle, so angles 4 and 5 are complementary.

2. Angles 1 and 4 are vertical angles. Vertical angles have the same measure, so

∠4=∠1=37°

3. From 1,

∠4+∠5=90°

From 2

∠1=∠4

Since ∠1=40°, then ∠4=40°

So,

∠5=90°-40°=50°

Answer:

4.9 & 4.2

Step-by-step explanation:

First, we will have to define mode,

“Mode is the most frequently occurring value of the given data.”

The value with the greatest frequency is called mode. In order to find mode, we have to skim through the data. The value which is repeated most is the mode of the given data. A data can have more than one modes.

For the above data,

4.9 is repeated 3 times.

4.2 is repeated 3 times.

These both numbers have highest frequency in the data.

So the modes are 4.9 and 4.2 ..  

Answer:

So the modes are 4.9 and 4.2

Answer:

Hmm... None of these choices seem to be correct.

Step-by-step explanation:

The exact dimensions of the TV are approximately 14 inches by [tex]14\sqrt{3}[/tex] inches, which simplifies to 14 inches by 142 inches

The correct answer is:

 B. 14 inches by 142 inches.

To find the exact length and width of the TV, we can use the properties of a 30-60-90 right triangle. In such a triangle, the side lengths are related as follows: the length of the side opposite the 30-degree angle is [tex]\( \frac{1}{2} \)[/tex] times the length of the hypotenuse, and the length of the side opposite the 60-degree angle is [tex]\( \frac{\sqrt{3}}{2} \)[/tex] times the length of the hypotenuse.

Given that the diagonal of the TV forms the hypotenuse of two 30-60-90 right triangles, let's denote the length and width of the TV as [tex]\( L \)[/tex] and [tex]\( W \)[/tex] respectively, and the length of the diagonal as [tex]\( D \).[/tex]

We have the following equations:

[tex]\[ L = \frac{1}{2}D \][/tex]

[tex]\[ W = \frac{\sqrt{3}}{2}D \][/tex]

Given that the diagonal [tex]\( D = 28 \)[/tex] inches, we can substitute this value into the equations to find the exact length and width:

[tex]\[ L = \frac{1}{2} \times 28 = 14 \text{ inches} \][/tex]

[tex]\[ W = \frac{\sqrt{3}}{2} \times 28 \approx 14\sqrt{3} \text{ inches} \][/tex]

Now, we need to rationalize the denominator for the width:

[tex]\[ W = 14\sqrt{3} \times \frac{\sqrt{3}}{\sqrt{3}} = \frac{42}{\sqrt{3}} \][/tex]

To rationalize the denominator, multiply both numerator and denominator by[tex]\( \sqrt{3} \):[/tex]

[tex]\[ W = \frac{42\sqrt{3}}{3} = 14\sqrt{3} \text{ inches} \][/tex]

So, the exact dimensions of the TV are approximately 14 inches by [tex]14\sqrt{3}[/tex] inches, which simplifies to 14 inches by 142 inches. Therefore, the correct answer is B.

Complete question:

The diagonal of a TV is 28 inches long. Assuming that the diagonal form a pair of 30-60-90 right triangles, what are the exact length and width of the TV?

A. 55 inches by 568 inches

B. 14 inches by 142 inches

C. 56 inches by 56.5 inches

D. 14 inches by 14.5 inches

Step-by-step explanation:

Answer:

The value of x is 10, and the value of y is 6

Step-by-step explanation:

ABC and GEF are congruent

so

x - 8 = 2

x = 10

x - y = 4

10 - y = 4

y = 10 - 4

y = 6

Answer

x = 10, y = 6

Answer:

x = 10 and y = 6

Step-by-step explanation:

In the given figure ΔABC and ΔGEF are congruent which means all the corresponding sides of the given triangles should be congruent.

So measure of AC = mfg

x - 8 = 2

x = 2 + 8

x = 10

Similarly mBC = mEF

x - y = 4

10 - y = 4

y = 10 - 4 = 6

Therefore, answer are x = 10 and y = 6

Answer: first 20 second 35

Step-by-step explanation:

If you don’t know the tax price/value then you can’t add that on the total amount. So, if we don’t know the value of that we can just forget about it for now.

You do $10.19-$1.25 (to get just the price of the pens) =$8.94

To get the value of one pen just do $8.94 divided by 6 (the total number of pens)=$1.49

$1.49=Price for one pen

For this case we must find three points that satisfy the following equation:

[tex]x-4y = -18[/tex]

So:

[tex]-14-4 (1) = - 14-4 = -18[/tex]

[tex]10-4 (7) = 10-28 = -18[/tex]

[tex]-30-4 (-3) = - 30 - (- 12) = - 30 + 12 = -18[/tex]

Answer:

Thus, three points that meet the equation are:

(-14,1)

(10,7)

(-30, -3)

Three points that solve the equation x-4y=-18 are (0, 4.5), (-18, 0), and (-14, 1).

To find three points that solve the equation x-4y=-18, we can choose values for one variable and solve for the other. Here are three points that satisfy the given linear equation:

These points are part of the infinite set of solutions to the linear equation x-4y=-18.

Final answer:

To combine the expression 4 log x - 6 log (x+2) into a single logarithm, we use the exponentiation and division rules for logarithms to obtain log((x^4)/(x+2)^6).

Explanation:

To write the expression 4 log x - 6 log (x+2) as a single logarithm, we can apply log rules.

The logarithm of a number raised to an exponent is the product of the exponent and the logarithm of the number: log(x^n) = n log x.

The logarithm of a product of two numbers is the sum of the logarithms of the two numbers: log xy = log x + log y.

The logarithm of the number resulting from the division of two numbers is the difference between the logarithms of the two numbers: log(x/y) = log x - log y.

Using these rules, we can

rewrite the given expression:

4 log x - 6 log (x+2) can be rewritten as log(x^4) - log((x+2)^6), which simplifies to log((x^4)/(x+2)^6) according to the division rule for logarithms.

The expression [tex]4 log x - 6 log (x+2)[/tex] can be simplified as a single logarithm by using the logarithm properties of exponents and division, resulting in [tex]log(x^4 / (x+2)^6).[/tex]

The student is asking to write the expression [tex]4 log x - 6 log (x+2)[/tex] as a single logarithm. To do this, we recall two important properties of logarithms:

Using these properties, we can rewrite the expression:

Therefore, the expression [tex]4 log x - 6 log (x+2)[/tex] written as a single logarithm is[tex]log(x^4 / (x+2)^6).[/tex]
