The distance traveled by light in 1 minute = 18 million kilometers and the distance traveled by light in 1 second = 0.3 million kilometers.

We are given that -

The distance traveled by light in 10 minutes = 180 million km.

Now we have to find the distance traveled by light in 1 minute.

Using the unitary method, we get -

Distance traveled by light in 1 min = 180000000 / 10

Distance traveled by light in 1 min = 18 million kilometers

Now we have to find the distance traveled by light in 1 second.

We know that 1 minute= 60 seconds,

Thus, In 60 seconds light travels a distance of = 18 million kilometers. (from above)

therefore, in 1 second light would travel a distance of = 18 million / 60

                                                                                         = 0.3 million km

Hence, the distance traveled by light in 1 second = 0.3 million kilometers.

The water level is rising at a rate of 0.0764 cm per second.

Using implicit differentiation, it is found that the water level is rising at a rate of 0.0764 cm per second.

The volume of a cone of radius r and height h is given by:

V = πr²h/3

Applying implicit differentiation, the rate of change is given by:

dV/dt = 2πr/3 dr/dt + πr²/3 dh/dt

In this problem:

The radius is constant, thus dr/dt = 0

Height of 5 cm and radius of 3 cm, thus h = 5, r=3.

Water poured at a rate of 2 cm³/s, thus dV/dt = 2

Then

dV/dt = 2πr/3 dr/dt + πr²/3 dh/dt

2 = 25π/3 dh/dt

dh/dt = 6/25π

dh/dt = 0.0764

The water level is rising at a rate of 0.0764 cm per second.

Different x values must be taken into account in order to graph h (x). So the graph of the h(x) is given below.

In the given question, we use the graphs of f and g to graph h(x) = (f + g)(x).

A diagram that compares the fluctuation of one variable to that of one or more other variables, such as a collection of points, lines, line segments, curves, or regions.

The graph is given below:

h (x) = (f + g) (x)

The function h(x) can be written as

h (x) = f (x) + g (x)

Different x values must be taken into account in order to graph h (x).

h (0) = f (0) + g (0) = 2 - 1 = 1

h (1) = f (1) + g (1) = 3 + 0 = 3

h (2) = f (2) + g (2) = 1 + 0.5 = 1.5

h (3) = f (3) + g (3) = 2 + 0 = 2

Store D provides the best value, with the lowest price per donut at $0.24.

To determine which store has the best deal, you should compare the price per donut at each store.

At Store A, the BOGO offer means that you can buy one dozen donuts for the regular price of $6.35 and get a second dozen for free. This means that you are paying $6.35 for 2 dozen donuts, or $0.27 per donut.

At Store B, a dozen donuts cost $3.35, or $0.28 per donut.

At Store C, a dozen and a half donuts cost $6.50, or $0.26 per donut.

At Store D, if you buy 2 dozen donuts at $3.70 each and receive a 25% discount, you will pay $3.70 × 2 × (1 - 0.25) = $5.77 for 2 dozen donuts, or $0.24 per donut.

Thus, based on these prices, Store D is the best deal, as it has the lowest price per donut at $0.24.

y=6x+6 is the equation of the tangent line to the curve at point (0,6)

In order to fing the equation of tangent of any graph we need 2 things.

i . A point on the graph at which tangent need to be drawn.

ii . Slope a line on that point.

solpe of line = [tex]y^'[/tex]  =[tex]\frac{d(y)}{dx}[/tex]

=> d(6[tex]e^xcosx[/tex])/dx

in order to differentiate the above equation we have to use by parts

=> 6([tex]e^xcox-e^xsinx[/tex])

finding the slope at point(0,6)

[tex]y^'[/tex] = 6*(1*1-1*0)

=>6

so slope is 6

now equation of line with slope 6 and point (0,6)

=> y-6 = 6(x-0)

=> y = 6x+6

step 2 : applying the formula

y – y1 = m(x – x1)

y – 5 = m(x – 6)

Answer:

x = 25

Step-by-step explanation:

The two interior angles equal the exterior angle.

6x - 12 = 3x + 2x + 13  Combine like terms

6x - 12 = 5x + 13  Subtract 5x from both sides of the equation

6x -5x - 12= 5x - 5x + 13

x - 12 = 13  Add 12 to both sides of the equation

x - 12 + 12 = 13 + 12

x = 25

The given population is 10%.

If the 10 % condition is met, a binomial distribution can be used to approximate the number of successes in a simple random sample. The 10% condition requires that the sample represents less than 10% of the population. Despite the fact that the sample size is far too tiny in comparison to the population, it is reasonable to infer that the trials of occurrences are independent. This suggests that the sample size n must be smaller than 10% of the population size N in this situation.

According to the 10% condition, sample sizes shouldn't exceed 10% of the population. Check the condition whenever samples are involved in statistics to make sure your findings are reliable. If you want to employ a typical normal model, some statisticians contend that a condition of 5% is preferable to a condition of 10%.

Hence we get the required answer.

If new automobile prices are roughly regularly distributed, with a mean of $17,000 and a standard deviation of $500, then it means that the majority of the prices paid for the car will fall within a certain range.

Specifically, approximately 68% of the prices paid will be within one standard deviation of the mean, which in this case would be between $16,500 and $17,500.

Approximately 95% of the prices paid will be within two standard deviations of the mean, which would be between $16,000 and $18,000. And approximately 99.7% of the prices paid will be within three standard deviations of the mean, which would be between $15,500 and $18,500. This demonstrates that the prices paid for the cars are generally consistent, with only a tiny percentage deviating from the mean and standard deviation-defined range.

The congruence theorem that would best prove the congruence of the triangles is SAS that is Side-Angle-Side.

What is congruence theorem?

Congruent refers to something that is "absolutely equal" in terms of size and form. The shapes hold true regardless of how we rotate, flip, or turn them. Draw two circles with the same radius, for instance, cut them out, then stack them on top of one another.

The figure, in this case a triangle, is congruent if and only if the corresponding sides and angles are equal in measurement. In this case we have BC being common to both triangles. Thus, one pair of corresponding sides is equal. Next, we have another pair of corresponding sides that are equal, AC and DC. Lastly, we have the included angles being equal to each other. Thus, the congruence theorem that would best prove the congruence of the triangles is SAS that is Side-Angle-Side.

An angle is formed when two straight lines or rays meet at a common endpoint.

The common point of contact is called the vertex of an angle. The word angle is from a Latin word that means ‘angulus,’ meaning “corner.”

There are many examples of an angle, such as cloth hangers, arrowheads, scissors, etc.

Symbol of Angle:

The symbol ∠ represents an angle. Angles are measured in degrees (°) using a protractor.

For example, 45 degrees is represented as 45°

Parts of Angles:

Vertex: A vertex is a corner of an angle, a point where two lines/sides meet.

Arms: The two sides of the angle, joined at a common endpoint.

Initial Side: It is also known as the reference line, a straight line from where an angle is drawn.

Terminal Side: The side up to which the angle measurement is done.

True. Adjusted R2 is always less than or equal to R2 in the multiple regression model.

A statistical method called regression links a response variable with one or more independence (explanatory) variables. A regression model can demonstrate whether changes in any or all of the independent variable are related to changes in the dependent variable.

Regress, from which the word "regression" is derived, means "to go back" in Latin (to something). Regression is the method that enables "going back" from muddled, challenging data to a simpler and more significant model in this manner. Forecasting, time series modeling, and determining the causal connection between variables are the three basic applications of regression analysis.
