what is the answer to the circumference of the base of a cylinder with a diameter of 6cm and height of 12cm

Answer:

y = -4x + 5

Step-by-step explanation:

Slope of the line passing through \((x_1,y_1)\) and \((x_2,y_2)\) is represented by,

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

Given line in the graph is passing through two points (0, 5) and (2, -3),

m = \(\frac{5+3}{0-2}\) = (-4)

Equation of the line passing through \((x_1,y_1)\) and slope m will be,

\(y-y_1=m(x-x_1)\)

Therefore, equation of the line passing through (0, 5) and slope = -4 will be,

y - 5 = -4(x - 0)

y - 5 = -4x

y = -4x + 5

answer

just put the -4 in the y spot and 5 in the x spot

Answer:  $3510

Step-by-step explanation:

There is 9 survey responses out of 50 and it wants to know for 600 instead of 50. So you would set up a proportion of 9/50  /600 then you would do 600 x 9 divided by 50 to get 108 then you would multiply that by profit per bike which is 32.50 to get $3510.

The figure above shows two circles, one inside the other. The equation x^2 + y^2 = 2 represents the smaller circle, while the larger circle is not explicitly defined in the question.

However, we can see from the graph that the center of both circles is at the origin (0,0) and that the larger circle has a radius twice as big as the smaller circle.

Therefore, the radius of the larger circle is 2 times the radius of the smaller circle, which is the square root of 2. So the answer is (a) √2.
The given equation of the circle is x^2 + y^2 = 2. To find the radius of this circle, we can rewrite the equation in the standard form of a circle: (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center and r is the radius.

In this case, the equation is already in the standard form with h = 0, k = 0, and r^2 = 2. Therefore, the radius of the larger circle is r = √2. So, the correct answer is a) √2.

Answer:

  7 yd

Step-by-step explanation:

The sum of horizontal measures is the same across the top and bottom:

  15 yd = 8 yd + ?

  7 yd = ? . . . . . subtract 8 yd from both sides

The missing side length is 7 yd.

a) The present value of $25,000 due 9 periods from now, discounted at 10%, is approximately $10,593.22.

b) The present value of $25,000 to be received at the end of each of 6 periods, discounted at 9%, is approximately $22,935.35.

(a) Present Value of $25,000 due 9 periods from now, discounted at 10%:

To calculate the present value, we need to discount the future cash flow of $25,000 back to its current value using the given discount rate of 10%. The formula to calculate the present value is:

Present Value = Future Value / (1 + Discount Rate)ⁿ

Where:

Future Value is the amount to be received in the future ($25,000).

Discount Rate is the rate at which we discount the future cash flow (10%).

'n' is the number of periods or years until the future cash flow is received (9 periods in this case).

Let's plug in the values into the formula and calculate the present value:

Present Value = $25,000 / (1 + 0.10)⁹

Calculating the denominator:

(1 + 0.10)⁹ = 1.10⁹ ≈ 2.36

Present Value = $25,000 / 2.36 ≈ $10,593.22

(b) Present Value of $25,000 to be received at the end of each of 6 periods, discounted at 9%:

In this case, we have a cash flow of $25,000 to be received at the end of each of 6 periods, discounted at 9%. Let's calculate the present value:

Present Value = $25,000 / (1 + 0.09)¹ + $25,000 / (1 + 0.09)² + ... + $25,000 / (1 + 0.09)^6

Calculating each discount factor:

(1 + 0.09)¹ ≈ 1.09

(1 + 0.09)² ≈ 1.1881

(1 + 0.09)³ ≈ 1.2950

(1 + 0.09)⁴ ≈ 1.4116

(1 + 0.09)⁵ ≈ 1.5386

(1 + 0.09)⁶ ≈ 1.6765

Plugging in the values and summing them up:

Present Value = $25,000 / 1.09 + $25,000 / 1.1881 + $25,000 / 1.2950 + $25,000 / 1.4116 + $25,000 / 1.5386 + $25,000 / 1.6765

Present Value ≈ $22,935.35

The equation of the conic with Points at (1,−1) directrix along x−y+1=0 and with eccentricity 2​ is 2xy - 4x -4y +1 = 0 .

Equation:

An equation is a formula that connects two expressions with the equal sign = to indicate that they are equal. Solving an equation involving variables involves determining which values ​​of the variables make the equation true. The variables for which the equation must be solved are also called unknowns, and the values ​​of the unknowns that satisfy the equation are called solutions of the equation. There are two types of comparisons: identity comparisons and conditional comparisons. The identity is true for all values ​​of the variable. Conditional comparisons are only true for certain values ​​of variables

The given system of equations do not have a solution since their related line equations have the same slope.

The given system of equations is:

-x + 5y = 3   .......... (1)

2x - 10y = 4   ........(2)

In Equation (1), add both sides by (-5y)

-x + 5y + (-5y) = 3 + (-5y)

-x = -3 - 5y

Multiply by (-1)

x = 3 + 5y

Substitute x = 3 + 5y into equation (2)

2x - 10y = 4

2.(3 + 5y) - 10y = 4

6 + 10y - 10y = 4

6 = 4 (False)

Since the last equation is false, we might suspect that the given system of solution does not have solutions.

We need to check the slope of both equations:

-x + 5y = 3

⇒ 5y = x + 3

⇒ y = 1/5 x + 3/5

2x - 10y = 4

⇒ -10 y = -2x + 4

⇒ y = (2/10) x - 4/10

⇒ y = 1/5 x - 2/5

We can see that both equations have the same slope, i.e. 1/5.

Hence, they do not have solutions since the lines are parallel to each other.

The parametric equations for the tangent line to the curve at the point x=e−5tcos3t,y=e−5tsin3t,z=e−5t; (1,0,1) are: x = -5t + 1; y = 3t and z = -5t + 1

To find the tangent line to the curve with the given parametric equations at the point (1,0,1), we need to first find the tangent vector at that point.

The vector function for the curve is r(t) = (e^-5tcos3t, e^-5tsin3t, e^-5t).

We can find the derivative of r(t) by taking the derivative of each component:

r'(t) = (-5e^-5tcos3t - 3e^-5tsin3t, -5e^-5tsin3t + 3e^-5tcos3t, -5e^-5t)

Now we can find the tangent vector at the point (1,0,1) by evaluating r'(t) at t=0 (since we are given the point (1,0,1) and not a specific value of t):

r'(0) = (-5cos0 - 3sin0, -5sin0 + 3cos0, -5) = (-5, 3, -5)

So the tangent vector at the point (1,0,1) is (-5, 3, -5).

To find the parametric equations for the tangent line, we can use the point-normal form of the equation for a plane:

(x - 1)/(-5) = (y - 0)/3 = (z - 1)/(-5)

Simplifying, we get:

x = -5t + 1
y = 3t
z = -5t + 1

So the parametric equations for the tangent line to the curve at the point (1,0,1) are:

x = -5t + 1
y = 3t
z = -5t + 1

the derivative dy/dx is equal to 1/3 based on the given information. It's important to note that this calculation assumes that the partial derivatives (∂F/∂x) and (∂F/∂y) are not zero at the given point (z.y.a).

n the given problem, we have an implicit equation ln(x+y+z) = x+2y+3z that defines z as a function of x and y. We are given the values dy = (-1, 5, -3).

To find the derivative dy/dx, we can use the total derivative formula and apply it to the implicit equation. The total derivative is given by dy/dx = - (∂F/∂x)/(∂F/∂y), where F = ln(x+y+z) - x - 2y - 3z.

Differentiating F partially with respect to x and y, we have (∂F/∂x) = 1/(x+y+z) - 1 and (∂F/∂y) = 1/(x+y+z) - 2.

Plugging in the given values of dy = (-1, 5, -3), we can calculate dy/dx = - (∂F/∂x)/(∂F/∂y) = -(-1)/(5-2) = 1/3.

Therefore, the derivative dy/dx is equal to 1/3 based on the given information. It's important to note that this calculation assumes that the partial derivatives (∂F/∂x) and (∂F/∂y) are not zero at the given point (z.y.a).

Using it's concept, it is found that the vertical asymptotes of the function \(f(x) = \frac{x + 2}{x^2 - 3x - 4}\) are given by:

In this problem, the function is:

\(f(x) = \frac{x + 2}{x^2 - 3x - 4}\)

The denominator is \(x^2 - 3x - 4\), which is a quadratic function with coefficients \(a = 1, b = -3, c = -4\), hence, it's roots are found as follows.

\(\Delta = b^2 - 4ac = (-3)^2 - 4(1)(-4) = 25\)

\(x_{1} = \frac{-(-3) + \sqrt{25}}{2} = 4\)
