Answer:

Base rate: $120

Rate: $2 per person

Equation: f(x)=2x+120

Step-by-step explanation:

If 30 people cost $180 and 50 people cost $220, the charge for 20 extra people is $40.  This means, \(\frac{220-180dollars}{50-30people}=\frac{40dollars}{20people}=2\frac{dollars}{person}\).

These values correspond to a base rate for the bus of $120.

The function for the cost per bus with x number of people on it would be:

\(f(x)=2x+100\)

This can be checked by using the values given in the problem:

\(f(30)=2(30)+120=180\\f(50)=2(50)+120=220\)

The base rate of $120 and $2 per person satisfies the given equation and established values.

The zero of the function are the roots of the function

The zero of the function is 30

The equation of the function is given as:

\(f(x) = 2 -4\sin(x)\)

Set the function to 0

\(2 -4\sin(x) = 0\)

Subtract 2 from both sides of the equation

\(-4\sin(x) = -2\)

Divide both sides by -4

\(\sin(x) = 0.5\)

Take the arc sin of both sides

\(x = \sin^{-1}(0.5)\)

Solve for x

\(x =30\)

Hence, the zero of the function is 30

The sky appears blue because of Rayleigh scattering while water appears blue due to selective absorption and scattering of light.

The blue color of the sky is a result of Rayleigh scattering which occurs when the Earth's atmosphere scatters shorter wavelengths of light (blue and violet) more efficiently than longer wavelengths (red and orange).

When sunlight enters the atmosphere, the blue light is scattered in all directions by the molecules and tiny particles present in the air creating the blue appearance of the sky.

Similarly, water appear blue due to selective absorption and scattering of light. Water molecules selectively absorb colors from the visible light spectrum and absorb longer wavelengths (such as red) more effectively than shorter wavelengths (such as blue).

Answer:

$90

Step-by-step explanation:

To find out how much money he can save by paying the total amount at the time of purchase, first you have to determine the total amount that Jackson would pay if he can agree to pay $250 down and $130 a month for 18 months:

$250+(130*18)=$2590

Then, you need to find the difference:

$2590-$2500=$90

According to this, the answer is that you will save $90 by paying the total amount at the time of purchase.

This question is based on the simply math calculation. Therefore, the money can he save is $90 by paying the total amount at the time of purchase.

Given:

Jackson wants to purchase a home theater system that sells for $2500. Either he can pay the total amount at the time of purchase or he can agree to pay $250 down and $130 a month for 18 months.

We need to determined money can he save by paying the total amount at the time of purchase.

According to the question,

To find out,  money he can save by paying the total amount at the time of purchase, first you have to determine the total amount that Jackson would pay if he can agree to pay $250 down and $130 a month for 18 months:

⇒ $250+(130 \(\times\) 18)=$2590

Now, calculating the difference:

⇒ $2590 - $2500 = $90

Therefore, the money can he save is $90 by paying the total amount at the time of purchase.

Thinking and cognition are related to reasoning, which requires using one's intellect. The study of logic focuses on how people can construct logically sound arguments using formal reasoning. Deductive, inductive, and abductive reasoning are three examples of logical reasoning that can be used to further break down reasoning. Aristotle distinguished between logical discursive reasoning (reason proper) and intuitive reasoning, noting that the former may lean toward the subjective and the personal, despite being correct. While logical and intuitive styles of reasoning might clash in certain social and political circumstances, in others they are considered as complimentary rather than competitive.

Step-by-step explanation: add 50 to 280 :)

The length of portion BC of the cloth is approximately 5.8709 inches.

To find the length of portion BC of the cloth, we need to use trigonometric functions.

In this case, we can use the cosine function.

Given that the adjacent side to angle B is labeled BC and the hypotenuse is labeled 7 in, we can apply the cosine function, which is defined as the adjacent side divided by the hypotenuse:

cos(angle) = adjacent / hypotenuse

In this scenario, the angle we are considering is 33 degrees.

Therefore, we have:

cos(33°) = BC / 7 in

To isolate BC, we can rearrange the equation:

BC = 7 in \(\times\) cos(33°)

Calculating this expression, we find:

BC ≈ 7 in \(\times\) 0.8387 (rounded to four decimal places)

BC ≈ 5.8709 in.

Answer:

To calculate 2 3/4 of 500 grams, follow these steps:

1. Convert the mixed number to an improper fraction:

2 3/4 = (2 x 4 + 3)/4 = 11/4

2. Multiply the improper fraction by 500:

11/4 x 500 = (11 x 500)/4 = 2,750/4

3. Simplify the fraction by dividing the numerator and denominator by their greatest common factor, which is 2:

2,750/4 = (2 x 1,375)/(2 x 2) = 1,375/2

Therefore, 2 3/4 of 500 grams is equal to 1,375/2 grams or 687.5 grams.

Since the y-intercept of the line is (0,1) and the line passes through the point (2,4) which is also satisfied by the equation of the line, the given equation represents the graph of the line.

The slope-intercept form of a line is y = mx +c where m is the slope of the line and c is the y-intercept.

The given equation of the line is y = (3/2)x + 1.

To find the y-intercept of the line, substitute x = 0 into the given equation,

y = (3/2)(0) + 1

y = 1

Note that the y-intercept of the graph of the line is also 1.

The graph of the line passes through points (2,4).

To verify whether the equation satisfies the coordinates of (2,4) or not, substitute the coordinates of the point into the given equation:

4 = (3/2)(2) + 1

4 =4

The equation is true.

Hence, it can be said that the given equation represents the graph of the line.
