Answer:I believe it's -5√41/41

Step-by-step explanation:

The value of [tex]cos\theta[/tex] will be [tex]-0.7813[/tex].

If the point [tex](-5.-4)[/tex] were rotated around the origin, it would form a circle of radius [tex]r[/tex].  Also, if the point were projected to the x-axis, a right-angled triangle would be formed. Then, the value of [tex]cos\theta[/tex], could be obtained by the  formula

[tex]cos\theta=\dfrac{x}{r}[/tex]

where

[tex]x=\text{the side of the triangle opposite the reference angle of }\theta\\r=\text{the radius of the circle}[/tex]

From the point on the terminal side

[tex](x,y)=(-5,-4)[/tex]

we can directly get the value of [tex]x[/tex]. But we need to calculate the value of [tex]r[/tex].

To calculate the value of [tex]r[/tex], make use of Pythagoras theorem

[tex]r=\sqrt{x^2+y^2}\\=\sqrt{(-5)^2+(-4)^2}\\=\sqrt{25+16}\\\approx6.4[/tex]

We can now proceed to find the value of [tex]cos\theta[/tex], since we have the values of [tex]x[/tex], and [tex]r[/tex]. Therefore,

[tex]cos\theta=\dfrac{x}{r}\\\\=\dfrac{-5}{6.4}\approx-0.7813[/tex]

Answer:

12.6491106

Step-by-step explanation:

With respect to the angle formed by the bottom of the

ladder with the ground

  cos T = 6/14 = 3/7  

 T = inverse-cosine(3/7) = 64.623006647 degrees

 sin(64.623006647) = h/14

 h = 14*sin(64.62300647) = 12.6491106

The question is missing parts. Here is the complete question.

Sheer Industries is considering a new computer-assisted program to train maintenance employees to do machine repairs. In order to fully evaluate the program, the director ofmanufacturing requested an estimateof the population mean time required for maintenance employees to complete the computer assisted training. Use 7.94 days as a planning value for the population standard deviation. (Round your answers up to the nearest whole number).

(a) Assuming 95% confidence, what sample size would be required to obtain a margin of error of 0.5 days?

(b) If precision statement was made with 90% confidence, what sample size would be required to obtain a margin of error of 3 days?

Answer: (a) n = 900

               (b) n = 18

Step-by-step explanation: Margin of Error represents the percentage of confidence your result will be different from the real population value.

It is calculated as

[tex]E=z\frac{\sigma}{\sqrt{n}}[/tex]

z is z-score related to the percentage of confidence

σ is population standard deviation

n is sample size

(a) Margin of error = 0.5

For a 95% confidence, z-score is 1.96.

Sample size will be:

[tex]E=z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]\sqrt{n}=\frac{z\sigma}{E}[/tex]

[tex]\sqrt{n}=\frac{1.96*7.64}{0.5}[/tex]

[tex]\sqrt{n} =30[/tex]

n = 900

For a 95% confidence, margin of error of 0.5 days, sample size required would be 900.

(b) Margin of error = 3

z-score for 90% confidence = 1.645

Solving for sample size:

[tex]\sqrt{n}=\frac{z\sigma}{E}[/tex]

[tex]\sqrt{n}=\frac{1.645*7.64}{3}[/tex]

[tex]\sqrt{n}=4.2[/tex]

n = 18

It would be required, to obtain a margin of error of 3 days, a sample size of 18 maintenance employees.

Answer:

(4, 2) to (-2, 4) to (-4, -2).

Step-by-step explanation:

This 90 degree rotation depends on the direction of the rotation.  I'm assuming clockwise here.

So (4, 2) rotated 90 degrees puts the point at (-2, 4).

Another 90 degrees (therefore total 180 degrees), and we get to (-4, -2).

Answer:

The cost of buying salad per pound) is more than or equal to $4.50.

Step-by-step explanation:

The inequality represents the cost of at least $4.50 will be x ≥ 4.50 thus option (A) is correct.

A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.

In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.

As per the given,

The cost of salad is at least $4.50 thus means it is the minimum cost so x ≥ 4.50 refers to the cost equal and more than $4.50.

Hence "The inequality indicates that the price will be x ≥ 4.50, which must be at least $4.50".

Hello!

[tex]\large\boxed{a = 13m/s^{2}}[/tex]

Use the equation F = m · a to solve where:

F = total force (N)

m = mass (kg)

a = acceleration (m/s²)

We are given the force and mass, so we can plug these values into the equation to solve.

However, mass is used in kilograms, so we must convert from grams to kilograms:

1 kg = 1000 grams

Convert using dimensional analysis or proportions:

[tex]500 g* \frac{1 kg}{1000g} = 0.5kg[/tex]

Plug in the force and mass to solve:

6.5 = 0.5(a)

Divide both sides by 0.5 (Multiply by 2)

a = 13 m/s²

1[tex]\frac{39}{70}[/tex] pounds

Step-by-step explanation:

To find the remaining amount of money available left to buy gummy bears, we need to find the amount of money already spent on jelly beans.

Amount of money spent on jelly beans = 1[tex]\frac{3}{4}[/tex] × 3.90

                                                                 = 6.825

Amount of money left for gummy bears = 15-6.825

                                                                  = 8.175

Pounds of gummy bears bought = 8.175 ÷ 5.25

                                                      = 1[tex]\frac{39}{70}[/tex] pounds

If David already has 7/4 pounds of jelly beans, then 1.55 pounds of gummy bears can he buy.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

To determine the remaining amount of money available left to buy gummy bears, we have to find the amount of money already spent on jelly beans.

Amount of money spent on jelly beans;

= 7/4 × 3.90

 = 6.825

Amount of money left for gummy bears ;

= 15-6.825

= 8.175

Thus Pounds of gummy bears bought = 8.175 ÷ 5.25

                                                     = 1.55 pounds

Hence, If David already has 7/4 pounds of jelly beans, then 1.55 pounds of gummy bears can he buy.

Answer:

42

Step-by-step explanation:

If you divide any known side of PQRS by the same side on ABCD, it will equal 1.4. So if you did 49/35 or 56/40, each time you would get 1.4. Then, you just multiply 1.4 with RSs similar side, which is CD. 1.4 multiplied by 30 equals 42.

b) 8/9, -3.3(And I say its -3.3, because you need to write it in its original form.), so far its 8/9, -3.3, -8, -15.

c) Because the absolute value is the positive value of that number. (i.e, -3 is 3 places away from 0, so it's absolute value would be 3.)

Step-by-step explanation:

72.99% of days have a high temperature between 66 and 80 degrees.

It is the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.

here, we have,

Let random variable x denote the daily temperature in a variation resort city.

then E(x) = μ = 75

and S.D. = √var(x) = σ = 6

x is approximately normal

x ≈ N(75, 6²)

then Z = (X - 75) / 6

Z ~ N(0,L)

P(66< x < 80) = P((66-75 / 6) < (x - 75 / 6) < 20 - 75 / 6)

= P( -1.5 < z < 0.23), where Z = (x - 75 / 6)

=P(z<0.23) - P(z ≤ -1.5)

= 0.7967 - 0.0668

= 0.7299

P(66< x < 80) = 0.7299

Therefore, 72.99% of days have a high temperature between 66 and 80 degrees.
