Answer:

the derivative of given function is

[tex]cos(cos^2 x )(-sin 2 x)[/tex]

Step-by-step explanation:

Step :-

using chain rule formula [tex]\frac{d y}{d x} = \frac{d y}{d u} X\frac{d u}{d x}[/tex]

let [tex]Y = sin(cos^2 x)[/tex]  ...........(1)

[tex]\frac{d(sin x)}{d x} = cos x[/tex]

Differentiating equation (1) with respective to x,we get

[tex]\frac{d y}{d x} = cos(cos^2 x) \frac{d}{d x} (cos^2 x)[/tex]........(2)

we will use again formula

[tex]\frac{d(cos x)}{d x} = -sin x[/tex]

[tex]\frac{d (x^{2} )}{d x} =2 x[/tex]

From (2) equation we will get solution is

[tex]\frac{d y}{d x} = cos (cos^2 x) (2 cos x (\frac{d(cos x)}{dx} )[/tex]  ........(3)

again simplification the equation (3) we will get

[tex]\frac{d y}{d x} = cos(cos^2 x)(2 cos x(-sin x))[/tex] ........(4)

by using trigonometry formula

[tex]2 sin x cos x = sin2x[/tex]

now the equation (4) we get final solution is

[tex]\frac{d y}{d x} = cos(cos^2 x)(- sin2x)[/tex]

Answer:

[tex](5m - \frac{1}{5})^{3}[/tex]

Step-by-step explanation:

We have to write the following expression as a power of a binomial.

The expression is [tex]125m^{3} - 15m^{2} + \frac{3}{5}m - \frac{1}{125}[/tex].

Now, we have to rearrange the given expression.

[tex]125m^{3} - 15m^{2} + \frac{3}{5}m - \frac{1}{125}[/tex]

= [tex](5m)^{3} - 3(5m)^{2}(\frac{1}{5}) + 3(5m)(\frac{1}{5})^{2} - (\frac{1}{5})^{3}[/tex]

= [tex](5m - \frac{1}{5})^{3}[/tex] (Answer)

Since we know the identity as (a - b)³  = a³ - 3a²b + 3ab² - b³.

Answer:

5 people

Step-by-step explanation:

This is a subtraction problem.

45 - 40 = 5

There are 45 people wanting to ride the carousel, but since it can hold only 40 people, 5 people will have to wait for the next ride.

This is a simple arithmetic problem. There are 45 people waiting in line and the carousel can hold 40 people. To find out how many people will need to wait for the next ride, we subtract the number of people the carousel can hold from the number of people waiting in line:

So, 5 people will need to wait for the next ride.

For this case we have the following statement:

Concha is making dresses, if she has made 2/3 of 6 dresses. How many fractions of dresses does she have left to finish? How many dresses have you already made?

If Concha has made [tex]\frac {2} {3}[/tex] of 6 dresses we have:

[tex]\frac {2} {3} * 6 = \frac {6 * 2} {3} = \frac {12} {3} = 4[/tex]

So we have to:

[tex]\frac {3} {3} - \frac {2} {3} = \frac {1} {3}\\6 * \frac {1} {3} = 2[/tex]

Thus, Concha must make 2 dresses to complete all 6. This represents[tex]\frac {1} {3}.[/tex]

The value of function g (4) will be 31.

What is Function?

A relation between a set of inputs having one output each is called a function.

Given that;

F(x) is an even function.

So, F(-x) = F(x)

And, f(-6) = 8

Now,

The function is,

g(x) = 4 f(x+2) - 1

Find the value of g(4), substitute x = 4 in above equation as;

⇒ g (4) = 4 f(4 + 2) - 1

⇒ g (4) = 4 f (6) - 1

Since, F(x) is an even function.

So, F(-8) = F(8)

Hence, We get;

⇒ g (4) = 4 × 8 - 1

⇒ g (4) = 32 - 1

⇒ g (4) = 31

Thus, The value of function g (4) will be 31.

The point (4,60) on a graph in the context of a bicyclist traveling likely represents that the bicyclist traveled a distance of 60 units in a time of 4 units, where the exact units would depend on the graph's axes' labels.

In go math books page 131, the point (4,60) typically represents a point on a graph or chart. In the context of a bicyclist traveling, the two numbers in the point likely stand for two different values or measurements. The first number '4' could represent time elapsed (for example, 4 hours or 4 minutes) and the second number '60' could possibly represent the corresponding distance traveled by the bicyclist (for example, 60 miles or 60 meters). Therefore, the point (4,60) could mean that the bicyclist traveled a distance of 60 units in a time of 4 units. The exact meanings of '4' and '60' would depend on the labels of the x-axis and y-axis of the graph.

The point (4,60) likely represents that after 4 units of time, the bicyclist has traveled 60 units of distance. This is typically used to interpret motion on a distance-time graph in kinematics, which is a branch of physics.

In the context of a Go Math book, the point (4,60) on a graph usually represents two distinct pieces of information about an event or a scenario. For instance, if we're considering the motion of a bicyclist, the point (4,60) might represent that after 4 units of time (such as 4 minutes or 4 hours), the bicyclist has traveled 60 units of distance (such as 60 meters or 60 miles). However, without the specific context or the content of page 131, it's challenging to determine the exact meaning of the point.

In Figure 24.7, which describes the motion of a motorist, time is on the y-axis and distance on the x-axis, which is a common convention for distance-time graphs in motion problems. Therefore, if (4,60) were a point on such a graph, 4 would likely represent the time elapsed and 60 the distance traveled.

Understanding points on these graphs helps students to visualize and interpret different aspects of motion, such as speed, displacement, and acceleration, contributing greatly to their grasp of kinematics of physics

Final answer:

While a correlation of 0.67 suggests a positive relationship between loud music and poor hearing, it does not confirm causation. Many factors contribute to hearing loss, and while loud music is a significant risk factor for noise-induced hearing loss, one cannot definitively conclude it causes poor hearing without considering other variables.

Explanation:

The correlation coefficient of 0.67 between poor hearing and loud music indicates a positive and moderate relationship between the two variables, suggesting that people who listen to loud music tend to have poorer hearing. However, correlation does not imply causation. While loud music can be one of the factors contributing to poor hearing, it is important to remember that other factors can also lead to hearing loss, such as age, genetics, infections, and other environmental noises. Therefore, while the correlation is significant, we cannot conclude with certainty that poor hearing is exclusively caused by listening to loud music.

Noise-induced hearing loss can indeed happen from prolonged exposure to sounds of high intensity. For example, listening to music through earbuds at maximum volume, which can be around 100-105 decibels, increases the risk of hearing loss and can cause noise-induced hearing loss after 15 minutes of exposure. The impact of sound intensity on hearing health is undeniable, but when determining causality, a deeper investigation into other possible contributing factors must also be taken into account.

Answer:

351.7227778°

Step-by-step explanation:

The conversion of 351°41’142” into decimal degrees involves expressing minutes and seconds as fractions of a degree. This results in approximately 351.7227 degrees.

To convert degrees, minutes, and seconds to decimal degrees, we express the minutes and seconds as fractions of a degree. Degrees are already expressed in decimal form, so 351° remains 351. However, 1 minute equals 1/60 of a degree, while 1 second equals 1/3600 of a degree. So, to convert 41 minutes into decimal degrees, we divide 41 by 60, which equals approximately 0.6833. And to convert 142 seconds into decimal degrees, we divide 142 by 3600, which equals approximately 0.0394. Then we add these values together with the original degrees to get the final answer: 351 + 0.6833 + 0.0394 equals approximately

351.7227 degrees

Final answer:

There are 72 possible outcomes in the experiment.

Explanation:

The total number of outcomes for the experiment can be found by multiplying the number of outcomes for each event.

For the first event, rolling a six-sided number cube, there are 6 possible outcomes (numbers 1 to 6).

For the second event, flipping a coin, there are 2 possible outcomes (heads or tails).

For the third event, rolling a six-sided number cube again, there are 6 possible outcomes.

To find the total number of outcomes, multiply the number of outcomes for each event: 6 x 2 x 6 = 72.

Therefore, there are 72 possible outcomes in this experiment.

Step-by-step explanation:

The Ortega family has 11/16 pound of confetti left for next year's fiesta after using 1/4 pound this year.

The Ortega family started with 15/16 pound of confetti for the celebration. They used 1/4 pound of confetti for the fiesta eggs. To find out how much confetti they have left, we need to subtract the amount used from the total amount they made.

To subtract these fractions, they need to have the same denominator. The fractions already have the same denominator here, which makes it simpler. So, we subtract 1/4 from 15/16:

Therefore, the Ortega family has 11/16 pound of confetti left for the next year's celebration.

The equation of line is [tex]y = \frac{-3}{4}x - 3[/tex]

Solution:

Given that line passes through the point (4, –6) and has a slope of Negative three-fourths

Given point is (x, y) = (4, -6)

[tex]slope = \frac{-3}{4}[/tex]

The equation of line passing through point (x, y) and slope "m" is given as:

y = mx + c ----- eqn 1

Where "m" is the slope of line and "c" is the y - intercept

Substitute (x, y) = (4, -6) and [tex]m = \frac{-3}{4}[/tex] in eqn 1

[tex]-6 = \frac{-3}{4} \times 4 + c\\\\-6 = -3 + c\\\\c = -6 + 3\\\\c = -3[/tex]

The required equation of line is given as:

[tex]\text{ Substitute } m = \frac{-3}{4} \text{ and } c = -3 \text{ in eqn 1 }[/tex]

[tex]y = \frac{-3}{4}x - 3[/tex]

B. 3/4

Step-by-step explanation:

Care with these types of graphs as the values are 2 rather than one on each axis.

Away from that, rate of change can also be named "slope" in which how many units up or down the y-value goes per x value. To find the slope or "rate of change" you want to use [tex]\frac{RISE}{RUN}[/tex] .

To find the rise over run you want to go up from any point where the x and y value line up to another. The origin or (0,0) can be used to do this. Look at point (8,6) to see this. Rise from the origin 6 times and run to the right 8 times. Rise OVER run so the rate of change can be shown as 6/8 which can be simplified to 3/4.
