cotx = [tex]\frac{cosx}{sinx}[/tex] , cosecx = [tex]\frac{1}{sinx}[/tex]

Consider the left side

[tex]\frac{1}{1-cos\alpha }[/tex] - [tex]\frac{1}{1+cos\alpha }[/tex]

-9 - 8x = -2(7 + 4x) pls help it won’t

Answers

Answer:

no solution

Step-by-step explanation:

Given

- 9 - 8x = - 2(7 + 4x) ← distribute

- 9 - 8x = - 14 - 8x ( add 9 to both sides )

- 8x = - 5 - 8x ( add 8x to both sides )

0 = - 5 ← this is not possible

This indicates the equation has no solution

Help ​

Answers

Answer:

OK mate don't freak out its easy

First things first x and y are height and base and 10cm is hypotenuse.

40degree is the angle

Now.

The sin angle is an trigonometric angle which deals with height and hypotenuse.

It's formulae is...... Sin angle =height /hypotenuse

So sin 40 = x/10

X= 10 * sin 40

X= 10*0.64

Hence x=6.4 cm

Remainder sin 40 is 0.64

Again

The cos angle is an trigonometric angle which deals with base and hypotenuse

It's formulae is...... Cos angle =base /hypotenuse

So cos 40 = y/10

Y= cos 40 *10

Y= 0.76*10

Hence y = 7.6cm

Remainder cos 40 = 0.76.

The proportion of values of X between -3 and 8, if ∼(5,4.2)
X

(

. Round your answer to three decimal places.

Answers

If I'm understanding the question correctly, you're saying that X is a random variable following a normal distribution with mean 5 and standard deviation 4.2, and you want to find the proportion of the distribution that lies in the interval (-3, 8). In other words, the probability

P(-3 < X < 8)

Transform X to Z, which follows the standard normal distribution with mean 0 and standard deviation 1, using the rule

X = µ + σZ   ==>   Z = (X - µ)/σ

where µ and σ are the mean and standard devation of X, respectively.

We have

P(-3 < X < 8) = P((-3 - 5)/4.2 < (X - 5)/4.2 < (8 - 5)/4.2)

… ≈ P(-1.904 < Z < 0.714)

… ≈ P(Z < 0.714) - P(Z < -1.904)

… ≈ 0.762 - 0.028 ≈ 0.734

The proportion of values of X between - 3 and 5 is 0.734

The expression ∼(5,4.2) gives the mean and standard deviation of X

Mean, μ = 5

Mean, μ = 5Standard deviation, σ = 4.2

Using the normal distribution :

The proportion of values of X is given as :

z = (x - μ) / σ

P(Z < z) - P(Z < z)

P(Z < (x - μ) / σ) - P(Z < (x - μ) / σ)

For X = - 3 and x = 8

P(Z < (8 - 5) / 4.2) - P(Z < (-3 - 5) / 4.2)

P(Z < 0.7143) - P(Z < - 1.90476)

0.76248 - 0.0284 = 0.73408

Hence, the proportion of values of X between - 3 and 5 is 0.734

Here is a data set:

1 2 3 3 4 4 4 4 5 5 6 7

What happens to the mean and standard deviation of the data set when the 7 is changed to a 70?

Your answer:

Answers

The mean is  4 because it is in the middle an it is used the most in the data set.

The mean shift to the right side of the data set and the standard deviation is increased.

What is mean?

It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.

It is given that:

The data set is:

1 2 3 3 4 4 4 4 5 5 6 7

The mean of the data = ∑x/n

The mean of the data = 4

The standard deviation of the data set = 1.58

If data changed:

1 2 3 3 4 4 4 4 5 5 6 70

The mean of the data = 9.25

The standard deviation of the data set = 18.36

Thus, the mean shift to right side of the data set and the standard deviation is increased.

what is the slope of the equation y= -3/4x+2 ?

Answers

The slope of that equation is 3/4

Answer: Slope = -3/4

Step-by-step explanation:

Background information

The given equation [y = -3/4x + 2] is in the form of slope-intercept form of linear equation.

The slope-intercept form of a linear equation is where one side contains just [y]. So, it will look like: y = mx + b where [m] is the slope and [b] is the y-intercept.

Match the given equation with the base form of the equation

y = (-3/4)x + 2

y = m x + b

Finalize the match result

m = -3/4

b = 2

Therefore, the slope of the equation [y = -3/4x + 2] is [tex]\boxed{-\frac{3}{4} }[/tex]

How many ounces of a 15​% alcohol solution must be mixed with 4 ounces of a 20​% alcohol solution to make a 17​% alcohol​ solution?

Answers

Answer:

6 ounces

Step-by-step explanation:

Let x = the number of ounces of the 15% alcohol solution needed to be mixed with the 4 ounces of 20% alcohol solution to obtain the 17% alcohol solution.

After converting the percentages to their decimal equivalents, set up the necessary equation as follows:

0.15x+0.20(4) = (x+4)(0.17) Simplify and solve for x.

0.15x+0.8 = 0.17x+0.68 Subtract 0.15x from both sides.

0.8 = 0.02x+0.68 Now subtract 0.68 from both sides.

0.12 = 0.02x Finally, divide both sides by 0.02

x = 6

You need to mix 6 ounces of 15% alcohol solution with 4 ounces of 20% alcohol solution to obtain 10 (x+4)ounces of 17% alcohol solution.

Answer:

Therefore 2 ounces of 11% alcohol solution must be mixed with 4 ounces of 20%alcohol to make a 17%alcohol solution

Step-by-step explanation:

Let x ounces of 11% alcohol must be mixed with the 2 ounces of 20% alcohol.

The amount of alcohol in 4 ounces solution is=   ounces

                                                             = 0.8 ounces

The amount of alcohol in x ounces  solution is=   ounces

                                                                             = 0.11 x ounces

Total amount of alcohol is = (4+x) ounces

According to the problem,

Therefore 2 ounces of 11% alcohol solution must be mixed with 4 ounces of 20%alcohol to make a 17%alcohol solution

If x varies directly as y, and x=45 when y=60, find x when y=36.

Answers

Answer:

x=31

Step-by-step explanation:

When x=45    y=60

And when y=36

First find how y became 36

For that let's take the amount as Z(to find how much was decreased)

60-z=36

60   =36+z

60-36=z

      14=z

Now subract 14 from 45

45-14

31

Therefore when y=36 x=31

Step-by-step explanation:

2 tan(60) = 2 * (sqrt(3)/2 = sqrt(3)

1 + tan^2(60) = 1/cos^2(60) = 1//1/4 = 4

The answer is going to look a little convoluted but it should be correct.

The answer so far is sqrt(3) /4

sin(60) = sqrt(3)/2    

of the 4, two is needed to get sqrt(3)/2

So far then we have sin(60)/2

If we multiply by 2 as in (sin(60)/2) we get just sin(60)

2* sqrt(3) /4 then  = 2 sin(60)

It was similar to the European feudal system, but it was also very structured - an attribute not always associated with European feudalism. This political system was called the Bakuhan system. Baku comes from Bakufu, which describes how the Shogun used to control their private affairs inside each fief. Thus, Bakuhan refers to the co-existence of the Tokugawa Shogun with separate, independent governments across each of the fiefs. Since each Daimyo was employed by the Shogun, they managed to hold onto power across the whole of Japan.
