Answer:

Changing value of "c" changes the phase shift of the sine graph.

Step-by-step explanation:

Question says to find about how does the c value affect your sine graph.

General equation of sine function can be given as:

[tex]y=a\cdot\sin\left(bx-c)\right)+d[/tex]

In that formula, value of  "c/b" gives phase shift.

So changing value of "c" changes the phase shift of the sine graph.

Divide the area with the length ( 9 feet long)

Area: 63/9

= 7 feet long

7*9=63 ft 2

Answer: 7 feet long

7 feet.

The area of a rectangle is equal to its length times its height.

In this case, the area can be represented by 63 = 9 * w.

Divide both sides of the equation by 9 to get 7 = w.

This means the width is 7 feet.

Answer:

Step-by-step explanation:

You need to use trigonometry (SOHCAHTOA)

As from the focus angle -thetre- (65^o) you have the adjecent (x) and hypotenuse (the side opposite the right angle - 81.9m):

cos(θ) = adjacent/hypotenuse

cos (65) = x/81.9

as the opposite of dividing is mulitplying, you multiple both sides by 81.9

81.9*cos(65) = x

using calculator - in degree mode-

x = 34.6124

Thus it is the first choice, x = 34.61.

Answer:

The correct answer is first option

X = 34.61

Step-by-step explanation:

Points to remember

Trigonometric ratios

Sin θ  = Opposite side/Hypotenuse

Cos θ = Adjacent side/Hypotenuse

Tan θ = Opposite side/Adjacent side

From the figure we can see that a right angled triangle with base x and hypotenuse = 81.9.

One angle = 65°

To find the value of x

We have Cos θ = Adjacent side/Hypotenuse

Cos 65 = X/81.9

X = 81.9 * Cos 65

 = 81.9 * 0.4226  

 = 34.61

Therefore  X = 34.61

The correct answer is first option

Answer:

Step-by-step explanation:

If the price is linear, then the slope between each pair of points must be the same.

m = Δy/Δx

m = (150 - 70) / (5 - 1) = 20

m = (450 - 150) / (20 - 5) = 20

m = (1050 - 450) / (50 - 20) = 20

So the equation is indeed linear.  It has a slope of 20 and y-intercept of 50.

p = 20n + 50

Answer:

B. 0.56.

Step-by-step explanation:

That would be the number of sophomore / total number of people

= 77 / 137

= 0.56.

The probability that the randomly chosen person from this group is a sophomore is B. 0.56.

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Given that,

Total number of people attended in the school event = 137

Number of sophomores in the group = 77

To find the probability, we have to divide the number of desired outcomes by the total number of outcomes.

Here total number of outcomes is 137 and the number of sophomores is 77.

Probability = 77 / 137 = 0.562 ≈ 0.56

Hence the probability is 0.56.

Answer: 16,503,616 leagues²

Step-by-step explanation:

Assume that the Earth is a sphere. Then, you need to use the formula for calculate the surface area of a sphere:

[tex]SA=4\pi r^2[/tex]

Where r is the radius.

Divide the diameter by 2 to calculate the radius of the Earth:

[tex]r=\frac{2,292\ leagues}{2}\\r=1,146\ leagues[/tex]

Substituting values into the formula  [tex]SA=4\pi r^2[/tex], you get that the total surface of the Earth to the nearest whole number is:

 [tex]SA=4\pi (1,146\ leagues)^2=16,503,616\ leagues^2[/tex]

The correct answer is that the total surface area of Earth is approximately 510 million square kilometers.

To calculate the total surface area of Earth, we can use the formula for the surface area of a sphere, which is [tex]\( A = 4\pi r^2 \)[/tex], where r is the radius of the sphere. Since the diameter of Earth is given as 2292 leagues, we first need to convert leagues to kilometers. Historically, one league was approximately 5.556 kilometers.

 Using this conversion, the radius of Earth in kilometers is:

[tex]\[ r = \frac{2292 \text{ leagues} \times 5.556 \text{ km/league}}{2} \] \[ r = \frac{2292 \times 5.556}{2} \] \[ r = 1146 \times 5.556 \] \[ r \approx 6337.536 \text{ km} \][/tex]

Now, we can calculate the surface area using the radius:

[tex]\[ A = 4\pi r^2 \] \[ A = 4\pi (6337.536 \text{ km})^2 \] \[ A = 4\pi (404,089,630.24 \text{ km}^2) \] \[ A \approx 4\pi (4.04 \times 10^9 \text{ km}^2) \] \[ A \approx 4 \times 3.14159 \times 4.04 \times 10^9 \text{ km}^2 \] \[ A \approx 50.26548 \times 10^9 \text{ km}^2 \] \[ A \approx 5.026548 \times 10^{10} \text{ km}^2 \][/tex]

Rounding to the nearest whole number, the total surface area of Earth is approximately 510 million square kilometers.

Final answer:

To find the product of the binomials (x + ut)(9x - 8ut), we use the FOIL method and combine like terms, resulting in the expression 9x² + uxt - 8u²t².

Explanation:

To find the product of the binomials (x + ut)(9x - 8ut), we will use the distributive property (also known as the FOIL method in this case), which involves multiplying each term in the first binomial by each term in the second binomial:

Combining like terms, the final product is:

9x² + 9uxt - 8uxt - 8u²t²

Since 9uxt and -8uxt are like terms, we can simplify further:

9x² + uxt - 8u²t²

Answer:

B {(0,-4),(2,6)(,4,16)

Step-by-step explanation:

Answer:

x = - 4, x = 0, x = 1

Step-by-step explanation:

To find the zeros equate p(x) to zero, that is

3x³ + 9x² - 12x = 0 ← divide through by 3

x³ + 3x² - 4x = 0 ← factor out x from each term

x(x² + 3x - 4) = 0

x(x + 4)(x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x = 0

x + 4 = 0 ⇒ x = - 4

x - 1 = 0 ⇒ x = 1

Answer:

11,400.0

Step-by-step explanation:

There needs to be 40 employees per every 3 supervisors, so this means multiplication, or division, but I went with the multiplication route.

285 x 40 = 11,400.

11,400 / 40 = 285.

The reason I multiplied 285 by 40 is because the supervisors was the main piece to the puzzle, and was much easier than if it gave you employees first, and that's when you'd divide by 3.

If there's 285 supervisors, you have the full amount of supervisors, now you need employees, so you are free to multiply by 40, since thats how many supervisors are available every 40 employees. I hope this helps.

To solve this problem, we'll first establish the ratio of employees to supervisors as given by the company policy. The policy states that for every 40 employees, there must be 3 supervisors.
To find the number of employees that can be supervised by a single supervisor, we'll divide the number of employees by the number of supervisors in that ratio.
So, for every 3 supervisors, there are 40 employees. We want to know how many employees would be there per 1 supervisor. Thus, we divide 40 (the number of employees) by 3 (the number of supervisors):
Number of employees per supervisor = \( \frac{40 \text{ employees}}{3 \text{ supervisors}} \)
Now, if there are 285 supervisors at the company, we can find out the total number of employees by multiplying the number of supervisors by the number of employees per supervisor.
Therefore, the total number of employees \( E \) is:
\( E = 285 \text{ supervisors} \times \frac{40 \text{ employees}}{3 \text{ supervisors}} \)
The "supervisors" unit cancels out, and we are left with only the "employees" unit.
Now let's do the multiplication. We divide 40 by 3 and then multiply the result by 285:
\( E = 285 \times \frac{40}{3} \)
Calculating that results in:
\( E = 95 \times 40 \)
\( E = 3800 \)
Thus, the company has 3,800 employees.

Step-by-step explanation:

Final answer:

In an isosceles triangle with a perimeter of 22 cm and one side of 6 cm, the other two sides must be equal in length and must be 8 cm each to satisfy the perimeter condition.

Explanation:

The question asks for the possible lengths of the other two sides of an isosceles triangle with a perimeter of 22 cm, where one side is already known to be 6 cm. In an isosceles triangle, the two other sides must be of equal length because an isosceles triangle has two sides that are the same.

Let's denote the length of these two equal sides as 'x'. The perimeter of a triangle is the sum of the lengths of all three sides:

6 cm + x + x = 22 cm
2x + 6 cm = 22 cm
2x = 22 cm - 6 cm
2x = 16 cm
x = 8 cm

Therefore, the other two sides of the triangle must each be 8 cm long.

It's important to note that all three sides of a triangle must satisfy the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. In this case, the other two sides cannot both be less than 6 cm, otherwise, they will not form a triangle with the third side of 6 cm. The solution provided meets this requirement.

Answer:

y = 3z - 2x

Step-by-step explanation:

Systems of equations can be solved by a number of know techniques, such as substitution, elimination or graphical approach.

We are required to solve the system of equations given via substitution;

2x + y = 3z

x + y = 6z

The question requires us to determine the value for y from the first equation, that could be substituted into the second equation.

We simply need to make y the subject of the formula from the first equation;

2x + y = 3z

To do this we subtract 2x on both sides of the equation;

2x + y -2x = 3z - 2x

y = 3z - 2x

This is the value of y from the first equation, that can be substituted into the second equation.

=10y - 5 = 3y - 12

=7y - 5 = -12

=7y = -7

y = 1

Answer:

y = -1

Step-by-step explanation:

to solve this equation, you would solve for y by isolating y on one side of the equation

5(2y - 1) = 3(y - 4) < distribute 5 into 2y - 1 and 3 into y - 4

5(2y - 1)

5 x 2y = 10y

5 x - 1 = -5

= 10y - 5

3(y - 4)

3 x y = 3y

3 x -4 = -12

= 3y - 12

we get the new equation:

10y - 5 = 3y - 12 < add 12 to both sides to eliminate -12 from the right side

+ 12              + 12

10y + 7 = 3y < subtract 10y from both sides

-10y        -10y

7 = -7y < divide both sides by -7 to isolate y

7/-7 = -1

-7y/-7 = y

-1 = y

our solution to the equation is y = -1. we can see if this is an answer by plugging it in and seeing if both sides are equal, but its not necessary. i will show the check anyway:

CHECK

5(2y - 1) = 3(y - 4) when y = -1

5(2(-1) - 1) = 3((-1)- 4)

5(-2 - 1) = 3( -1 - 4)

5(-3) = 3(-5)

-15 = -15

both sides check out so y = -1 is a solution to the equation

Answer:

2n² + n + 1

Step-by-step explanation:

                               4, 11, 22, 37

Difference between:  7, 11, 15

7,11,15 are all 4 apart. You divide the 4 by 2 to get 2n² (it is squared because you needed a second level to find the difference)

And then I knew you needed to put the original 2n² with the sequence we are trying to work out.

                                                                 2, 8, 18, 32

                                                                 4, 11, 22, 37

difference between the 2 sequences   2, 3 ,4 ,5 (which all has a difference of 1)  which means 1n or just  n.

So that's 2n² + n

I

The sequence is quadratic as the second difference is constant. The nth term expression can be established as 2n² for which the coefficient 2 is half of the second difference. Further, by matching the sequence to the nth term, we adjust the expression to 2n² + n + 1.

A key step to finding an expression for the nth term of this sequence is finding the difference between consecutive terms. For this particular sequence, you can see that the difference isn’t constant, thus, it's a quadratic sequence. However, if the second difference is constant, the nth term of the sequence is a quadratic:

The first differences are: 7(11-4), 11(22-11), 15(37-22), 19(56-37).

The second differences are 4(11-7), 4(15-11), 4(19-15).

Since the second difference is constant and equals to 4. We divide this by 2 to get 2. This is the coefficient of the n² term in our sequence. Thus, the first part of the nth term is 2n².

The next step is to write out the sequence of 2n², subtract this sequence from the original sequence, and identify the differences:

The difference above is clearly linear (increases by 1 each time) and thus the format for nth term has improved from 2n² to 2n²+n. So far this match has worked for the first 5 terms, but we need to look at the nth term to see if it works:

Original sequence: 4, 11, 22, 37, 56

Sequence of 2n²+n: 3, 10, 21, 36, 55

To match the original sequence, add 1 to each term in our sequence. The nth term is therefore 2n² + n + 1.

AB - C² = 3x³ + x² + 6x - 9 ⇒ last answer

Step-by-step explanation:

* Lets study the problem to solve it

- The variables are:

# A = x²

# B = 3x + 2

# C = x - 3

* At first lets find AB

∵ A = x² and B = 3x + 2

∴ AB = x²(3x + 2)

∵ x² × 3x = 3x³ ⇒ same base so we added the power

∵ x² × 2 = 2x² ⇒ coefficient of x² is 1 multiplied by 2

∴ AB = 3x³ + 2x²

* At second find C²

∵ C = x - 3

∴ C² = (x - 3)²

- To solve bracket to the power of 2 use this rule:

# square the first term + 1st term × 2nd term × 2 + square the 2nd term

∴ (x - 3)² = (x²) + (x) (-3) (2) + (-3)² = x² - 6x + 9

∴ C² = x² - 6x + 9

* Now lets find AB - C²

∵ AB - C² = 3x³ + 2x² - (x² - 6x + 9) ⇒ multiply the bracket by -ve sign

∵ -ve × -ve = +ve

∵ -ve × +ve = -ve

∴ AB - C² = 3x³ + 2x² - x² + 6x - 9 ⇒ Add the like terms

∴ AB - C² = 3x³ + x² + 6x - 9

* AB - C² = 3x³ + x² + 6x - 9
