The value of x is 8.1

Step-by-step explanation:

We can use SOH CAH TOA to find our answer.

In this acronym, O is the opposite side, A is the adjacent side, and H is the hypotenuse. S is for the SIN function. C is for the COS function. T is for the TAN function.

We can calculate the length of the string by using the COS function.

So we can say the tangent of angle \(\beta\) is the opposite side divided by the adjacent side.

\(tan( \beta)=\frac{O}{A}\)

We are given the angle and the opposite side. We are looking for the adjacent side.

Lets solve for \(A\).

Take the reciprocal of both sides.

\(\frac{1}{tan(\beta)} =\frac{A}{O}\)

Multiply both sides by \(O\).

\(\frac{1}{tan(\beta)} *O=A\)

We are given

\(\beta=56\textdegree \\O=12\)

\(\frac{1}{tan(56)} *12=A\)

\(A=8.0941022\)

A continuous function is a function that is defined for all values of the independent variable, and its graph has no breaks or jumps. A discontinuous function is a function that is not continuous, meaning there are values of the independent variable at which the function is undefined or has a break or jump in its graph.

A continuous function is a function that can be graphed without any breaks or jumps. This means that the graph of a continuous function is a single, unbroken curve that passes through all its points. Furthermore, a continuous function is defined for all values of the independent variable. This means that the function is defined for all points in its domain. On the other hand, a discontinuous function is a function that is not continuous, meaning there are values of the independent variable at which the function is undefined or has a break or jump in its graph. This means that the graph of a discontinuous function will have jumps or breaks. Furthermore, a discontinuous function is not defined for all values of the independent variable, meaning that there are certain points in the domain for which it is not defined. In conclusion, the main difference between continuous and discontinuous functions is that a continuous function is defined for all values of the independent variable and has no jumps or breaks in its graph, whereas a discontinuous function is not defined for all values of the independent variable and has jumps or breaks in its graph.

For given equation of circle radius is 6 unit and center is at (-2,1).

What is a circle?

A circle is a special kind of ellipse in which the eccentricity is zero and the two foci are coincident. A circle is also termed as the locus of the points drawn at an equidistant from the center. The distance from the center of the circle to the outer line is its radius. Diameter is the line which divides the circle into two equal parts and is also equal to twice of the radius.

The equation of circle in the plane is given as:

(x-h)^2 + (y-k)^2 = r^2

where (x, y) are the coordinate points

(h, k) is the coordinate of the center of a circle

and r is the radius of a circle.

Now,

Step-by-step explanation:

Answer:yes

Step-by-step explanation:

The solutions are:

1st part:

Part A: Rewriting the expression so that the greatest common factor (GCF) is factored completely is 2y(x³ + 9x - 5x - 45).

Part B: Rewriting the expression completely factored is 2y(x² + 9)(x - 5).

2nd part:

Part A:  each side is 3x+4

Part B: one side is  (4x-5y), and the other side is (4x+5y)

3rd part:

The vertex of the function is a minimum and the coordinate of the vertex of the function is (0.2, -2.4)

Here, we have,

1st part:

Here,

In order to rewrite the expression so that the greatest common factor (GCF) is factored completely, we would determine the coefficients of the expression as follows:

2x³y + 18xy − 10x²y − 90y

The coefficients include the following:

2, 18, 10, 90

The greatest common factor (GCF) of the above listed coefficients is equal to two (2) while y is the common term for the variables x³y, xy, x²y, and y.

Therefore, the greatest common factor (GCF) of this expression is 2y and it should be factored as follows:

2x³y + 18xy − 10x²y − 90y = 2y(x³ + 9x - 5x - 45)

Part B.

Rewriting expression completely factored, we have:

2x³y + 18xy − 10x²y − 90y = 2xy(x² + 9) - 10y(x² + 9)

2x³y + 18xy − 10x²y − 90y = (x² + 9)(2xy - 10y)

2x³y + 18xy − 10x²y − 90y = (x² + 9)2y(x - 5)

2x³y + 18xy − 10x²y − 90y = 2y(x² + 9)(x - 5)

2nd part:

part A

9x² +24x+16=

(3x)² +24x +4²=

(3x+4)² = (3x+4)(3x+4) so each side is 3x+4

Part B

16x² -25y²= (4x)² -(5y)²= (4x-5y)(4x+5y)

so one side is  (4x-5y), and the other side is (4x+5y)

3rd part:

The vertex of the function is a minimum and the coordinate of the vertex of the function is (0.2, -2.4)

Part A: What are the x-intercepts of the graph of f(x)

The function is given as:

f(x) = 5x^2 + 2x - 3

Expand the function

f(x) = 5x^2 + 5x - 3x - 3

Factorize the function

f(x) = (5x - 3)(x + 1)

Set the function to 0

(5x - 3)(x + 1) = 0

Solve for x

x = 3/5 and x =-1

Hence, the x-intercept is 3/5 and -1

Part B : Is the vertex of the graph of f(x) going to be a maximum or a minimum?

The vertex of the function is a minimum.

This is so because the leading coefficient of the function is positive

Here, we have:

f(x) = 5x^2 + 2x - 3

Differentiate and set to 0

10x + 2 = 0

Solve for x

x = -0.2

Substitute x = -0.2 in f(x) = 5x^2 + 2x - 3

f(0.2) = 5(0.2)^2 + 2(0.2) - 3

Evaluate

f(0.2) = -2.4

Hence, the vertex of the function is (0.2, -2.4)

Part C: What are the steps you would use to graph f(x)?

To do this, we simply plot the x-intercept and the vertex.

And then connect the points.

If Kurt company takes advantage of the purchase discount, they will pay $4900 to Marilyn company.

The terms of "2/10 n/40" indicate that Kurt company can take advantage of a 2% discount if they pay within 10 days. The full payment is due within 40 days.

To calculate the amount Kurt company will pay to Marilyn company if they take advantage of the purchase discount, we need to subtract the discount from the total amount.

The total amount of merchandise purchased is $5000.

To calculate the discount amount, we multiply the total amount by the discount percentage:

Discount amount = 2% of $5000 = 0.02 * $5000 = $100

Therefore, if Kurt company takes advantage of the purchase discount, they will pay $100 less than the total amount.

The amount Kurt company will pay to Marilyn company is:

Total amount - Discount amount = $5000 - $100 = $4900

Hence, if Kurt company takes advantage of the purchase discount, they will pay $4900 to Marilyn company.

The spring will stretch 1.5 times further when the 0.60 kg block is added to the 1.2 kg block.

To determine how much further the spring will stretch when a 0.60 kg block is added to the 1.2 kg block, we need to consider Hooke's Law, which states that the force exerted by a spring is directly proportional to the displacement from its equilibrium position.

Let's assume that the spring is initially stretched by a certain amount x when only the 1.2 kg block is attached. The force exerted by the spring is given by F = kx, where k is the spring constant.

When the 0.60 kg block is added, the total mass becomes 1.2 kg + 0.60 kg = 1.8 kg. The force exerted by the spring remains the same, but the total mass affects the acceleration of the system according to Newton's second law, F = ma.

Using F = ma, we can find the acceleration of the system: F = (1.8 kg)(9.8 m/s^2) = 17.64 N.

Since F = kx, we can rearrange the equation to find x: x = F/k.

Now, if we assume the spring constant k remains constant, the displacement x will increase by a factor of 1.8 kg/1.2 kg = 1.5.

Therefore, the spring will stretch 1.5 times further when the 0.60 kg block is added to the 1.2 kg block.

Answer:

radius of the pot is 24.5 cm

Step-by-step explanation:

r≈24.51cm

Circumference = 154 cm

Using the formula

C=2πr

Solving for r

2πr = 154

r ≈ 24.50986cm

The radius of the pot will be 24.52229299≅24.522 if the circumference of the pot is 154 cm.

             A circle is a Two-Dimensional closed figure that has no corners or edges. The Circle will have a diameter, radius and circumference.

The circumference of the circle is calculated by the formula,

                                                 C=2πr

           where,  C= Circumference of the circle

                         π= 3.14 (fixed value)

                         r= Radius of the circle

As given per the problem C= 154 cm, substitute this value in the formula and derive r

                                         => 2πr = 154

                                         =>  πr = 154/2

                                         =>  πr = 77

                                         => r = 77/π

                                         => r = 77/3.14

                                         => r= 24.52229299 ≅ 24.52

Therefore, radius(r) = 24.52

Step-by-step explanation:

Given

x 2 4 6 8

y 1 -2 -5 -8

Required

Determine the slope

First, pick any two corresponding x and y values.

\((x_1,y_1) =(2,1)\)

\((x_2,y_2) =(8,-8)\\\)

The slope (m) is then calculated using:

\(m = \frac{y_1 - y_2}{x_1 - x_2}\)

Substitute in, the x and y values

\(m = \frac{1 - (-8)}{2- 8}\)

\(m = \frac{1 +8}{-6}\)

\(m = \frac{9}{-6}\)

\(m = -\frac{9}{6}\)

Divide numerator and denominator by 3

\(m = -\frac{9/3}{6/3}\)

\(m = -\frac{3}{2}\)

Hence, the slope is -3/2

Julia will use 10 groups to arrange all of the CDs.

To determine the number of groups Julia will use to arrange all of the CDs, we need to find the greatest common divisor of the numbers 215, 125, and 330.

First, we can check if any of the numbers are divisible by 5:

215 is not divisible by 5

125 is divisible by 5 (125 ÷ 5 = 25)

330 is divisible by 5 (330 ÷ 5 = 66)

Now we divide 125 and 330 by 5:

125 ÷ 5 = 25

330 ÷ 5 = 66

Next, we check if any of the numbers are divisible by 2:

25 is not divisible by 2

66 is divisible by 2 (66 ÷ 2 = 33)

Now we divide 66 by 2:

66 ÷ 2 = 33

Therefore, the greatest common divisor of 215, 125, and 330 is 5 × 2 = 10.

Step-by-step explanation:

The exact length of the curve. y = 3 + 4x^3/2, 0 ≤ x ≤ 1 is L = ∫√(9+108x-144x^(5/2)) / √(9-16x^3) dx, from 0 to 1.

To find the length of the curve, we need to use the arc length formula:

L = ∫√(1+(dy/dx)^2) dx, where y = 3 + 4x^(3/2) and 0 ≤ x ≤ 1.

First, we need to find dy/dx:

dy/dx = (12x^(1/2))/2√(3 + 4x^(3/2))

dy/dx = 6x^(1/2)/√(3 + 4x^(3/2))

Now, we can substitute this into the arc length formula:

L = ∫√(1+(6x^(1/2)/√(3 + 4x^(3/2)))^2) dx, from 0 to 1.

Simplifying the inside of the square root, we get:

L = ∫√(1+(36x)/(3 + 4x^(3/2))) dx, from 0 to 1.

We can simplify this further by multiplying the numerator and denominator of the fraction by (3 - 4x^(3/2)):

L = ∫√(1+36x(3-4x^(3/2))/(9-16x^3)) dx, from 0 to 1.

Expanding the numerator, we get:

L = ∫√((9+108x-144x^(5/2))/(9-16x^3)) dx, from 0 to 1.

Simplifying the expression under the square root, we get:

L = ∫√(9+108x-144x^(5/2)) / √(9-16x^3) dx, from 0 to 1.

We can evaluate this integral using numerical methods, such as Simpson's rule or the trapezoidal rule, to get an approximation of the length of the curve. The exact length of the curve cannot be expressed in a finite number of terms, but it can be approximated to any desired degree of accuracy using numerical methods.

$21,500  this would be cause a person to be indifferent between Fund A and Fund B (i. E. , the EMVs would be the same)

EMV 1 = 0.2*10,000 + 0.3*2,000 + 0.5*-5,000 = $100EMV 2 = 0.2*6,000 + 0.3*4,000 + 0.5*-0 = $2,400.

Comparing both funds based on EMV calculations, Fund B shows a higher EMV. Therefore, to maximize expected value, we should invest in Fund B with an expected value of $2,400. First, his EMV for Fund A is not the same as Fund A's return being higher or lower in good economic conditions. Therefore, the EMC can also be higher or lower. But obviously the economy changes quickly sometimes. You don't always get the same return. So relying solely on returns is risky. Relying heavily on favorable economic conditions makes Fund A vulnerable to change and increases investor risk, so investors need to be more diversified. We can do the calculation:

Fund A return in good economy = Difference between A and B: EMV (Fund A) = EMV (Fund B) 0.2*X + 0.3(2,000) + 0.5(- 5,000) = 2 4,000.2X = 4,300X = $21,500.
