Cone Surface Area Calculation

surface area of cone slant height is 2 radius is 1

To find the surface area of a cone, we need to know the radius and slant height of the cone.

In this case, we are given that the radius (r) is 1, and the slant height (l) is 2. We can use the Pythagorean theorem to find the height (h) of the cone:

l^2 = r^2 + h^2

2^2 = 1^2 + h^2

4 = 1 + h^2

h^2 = 3

h = sqrt(3)

Now we can use the formula for the surface area of a cone:

A = πr^2 + πrl

Substituting the values we know:

A = π(1)^2 + π(1)(2)

A = π + 2π

A = 3π

So the surface area of the cone is 3π

To find the eigenvalues and eigenvectors of a 2x2 matrix, follow these steps:

Calculate the characteristic equation by subtracting the identity matrix I multiplied by the scalar λ from matrix A, and set the determinant of this resulting matrix equal to zero. The characteristic equation is given by det(A - λI) = 0.Solve the characteristic equation to find the eigenvalues (λ).

Let's assume we have a 2x2 matrix A:

  | a  b |

A = | c d |

To find the eigenvalues, we need to calculate the characteristic equation:

det(A - λI) = 0,

where I is the 2x2 identity matrix and λ is the eigenvalue.

A - λI = | a-λ b |

| c d-λ |

The determinant of this matrix is:

(a-λ)(d-λ) - bc = 0,

which simplifies to:

λ² - (a+d)λ + (ad - bc) = 0.

This quadratic equation gives us the eigenvalues.

Solve the quadratic equation to find the values of λ. The solutions will be the eigenvalues.

Once you have the eigenvalues, substitute each value back into the equation (A - λI)v = 0 and solve for v to find the corresponding eigenvectors.

For each eigenvalue, set up the homogeneous system of equations:

(A - λI)v = 0,

where v is the eigenvector.

Solve this system of equations to find the eigenvectors corresponding to each eigenvalue.

To find the eigenvalues and eigenvectors of a 2x2 matrix, follow the steps mentioned above. The characteristic equation gives the eigenvalues, and by solving the corresponding homogeneous system of equations, you can determine the eigenvectors.

The formula 2x/(x-7) - (x+7)/x therefore equals (x² + 49) / (x × (x-7)).

Mathematical expressions consist of at least two integers or factors, a minimum of one math procedure, and a sentence. It's possible to multiply, divide, add, or remove with this mathematical procedure.

To simplify the expression 2x/(x-7) - (x+7)/x, we need to find a common denominator.

First, we can rewrite the second term as (x+7)/(x × 1), so the expression becomes:

2x/(x-7) - (x+7)/(x × 1)

To find a common denominator, we need to multiply the first term by x/x and the second term by (x-7)/(x-7):

2x × x / (x × (x-7)) - (x+7) × (x-7) / (x × (x-7))

Simplifying the expression further, we get:

(2x² - (x² - 49)) / (x × (x-7))

Simplifying the numerator, we get:

(2x² - x² + 49) / (x × (x-7))

And finally, we can simplify the expression to:

(x² + 49) / (x × (x-7))

Therefore, the expression 2x/(x-7) - (x+7)/x is equivalent to (x² + 49) / (x × (x-7)).

Fiona must have bought 3 pairs of socks and 2 belts to spend $27.95 in all.

What is the linear equation?

A linear equation is defined as a function that has either one or two variables without exponents. It is a function that graphs to a straight line.

We can model the scenario with a system of two equations in two variables as follows:

a: number of pairs of socks purchased

b: number of belts purchased

The cost of each pair of socks is $4.95, so the total cost of a pairs of socks is 4.95a.

Similarly, the cost of each belt is $6.55, so the total cost of b belts is 6.55b.

The total amount Fiona spent is $27.95, so we can write:

4.95a + 6.55b = 27.95

This is the first equation in our system.

We also know that a and b are both non-negative integers, since Fiona cannot buy a negative number of socks or belts.

To model this restriction, we can add the following inequalities to the system:

a ≥ 0

b ≥ 0

Now we have a system of two equations and two inequalities:

4.95a + 6.55b = 27.95

a ≥ 0

b ≥ 0

We can use this system to solve for the values of a and b that satisfy all the constraints of the problem. We could use a variety of methods to solve the system, such as substitution, elimination, or graphing.

For example, one way to solve the system is to solve the first equation for b in terms of a:

b = (27.95 - 4.95a) / 6.55

Since b must be a non-negative integer, we can try plugging in different values of a and see which ones yield integer values of b.

For instance, if we let a = 0, then b = (27.95 - 4.950) / 6.55 = 4.27, which is not an integer. Similarly, if we let a = 1, then b = (27.95 - 4.951) / 6.55 = 3.42, which is also not an integer.

However, if we let a = 2, then b = (27.95 - 4.95*2) / 6.55 = 2.57, which is not an integer. Continuing in this way, we find that the first integer value of b occurs when a = 3, which gives:

b = (27.95 - 4.95*3) / 6.55 = 1.71 ≈ 2

Hence, Fiona must have bought 3 pairs of socks and 2 belts to spend $27.95 in all.

Two panes of glass cost $4.30.

Explanation

First find the cost of one pane of glass (the "unit cost")

7 panes of glass cost

$

15.05

, so one pane of glass costs

15.05

÷7∩

$2.15 ← cost of one pane of glass

Then use that answer to find the cost of two panes of glass

If one pane of glass costs $2.15, then 2 panes cost 2× $2.15 $4.30 ← cost of two panes of glass

Answer:

Two panes of glass cost $4.30.

Step-by-step explanation:

anything whole or complete is designated as 100%.

what is x% of that whole ?

well, we need to multiply the whole with the same factor we need to multiply 100 with to get x.

100×f = x

f = x/100

whole × f = x% of the whole

so, when we are looking for 5%, what did that mean ?

it means that x = 5, and f = 5/100.

therefore, 5% of $13 is

13 × 5/100 = 65/100 = 0.65

so,

basic cost = $13

tax rate = 5%

tax amount = $0.65

and

basic cost = $13

tax amount = $0.65

total cost = 13 + 0.65 = $13.65

as 5/100 = 0.05

we have seen that the tax amount is simply $13×0.05

and when we add the tax amount to the basic cost, we need to add $13×1 (basic cost) to the $13×0.05 (tax amount), and we get as total

total cost = $13×(1+0.05) = $13×1.05 = $13.65

so, the decimal factor we can use directly without going through all the detail above is : 1.05

The probability of event A given event B, denoted as P(A | B), is 0.750. The probability of event B given event A, denoted as P(B | A), is 0.900. A and B are not independent events because the conditional probabilities P(A | B) and P(B | A) are not equal to the marginal probabilities P(A) and P(B), respectively.

To find P(A | B), we use the formula:

P(A | B) = P(A ∩ B) / P(B)

In this case, P(A ∩ B) = 0.45 and P(B) = 0.60.

Plugging these values into the formula, we get

P(A | B) = 0.45 / 0.60 = 0.750.

To find P(B | A), we use the formula:

P(B | A) = P(A ∩ B) / P(A)

Here, P(A ∩ B) = 0.45 and P(A) = 0.50.

Substituting the values, we find

P(B | A) = 0.45 / 0.50 = 0.900.

A and B are not independent because the probabilities of A and B are affected by each other. If A and B were independent, then P(A | B) would be equal to P(A), and P(B | A) would be equal to P(B). However, in this case, both P(A | B) and P(B | A) differ from their respective marginal probabilities. Therefore, A and B are dependent events.

Therefore, Deanna will need 60 panels of artificial grass to cover the area.

To find out how many panels of artificial grass Deanna will need to cover the area, we can follow these steps:

Step 1: Calculate the total area of the space she wants to cover.

Area = Length × Width

Given that the length is 20 ft and the width is 12 ft:

Area = 20 ft × 12 ft = 240 square feet

Step 2: Convert the area to square inches since the grass panels are measured in square inches.

1 square foot = 12 inches × 12 inches = 144 square inches

240 square feet × 144 square inches/square foot = 34,560 square inches

Step 3: Calculate the number of panels needed by dividing the total area in square inches by the area of each panel.

Each panel has an area of 24 inches × 24 inches = 576 square inches.

Number of panels = Total area / Area of each panel

Number of panels = 34,560 square inches / 576 square inches = 60 panels

Therefore measurement of x is 15 units.

The value of x from the given right triangle is 20 units. Therefore, option C is the correct answer.

Triangle congruence theorem or triangle congruence criteria help in proving if a triangle is congruent or not. The word congruent means exactly equal in shape and size no matter if we turn it, flip it or rotate it.

From the given right triangle, we have ST = 9, TQ = 16 and RQ = x

From similar triangles,

Δ SRQ ⩭ Δ STR ------(1) {∵ RT 丄 Hypotenuse SQ}

Δ SRQ ⩭ Δ RTQ ------(2) {∵ Δ SRQ, Δ STR and Δ RTQ are similar triangles}

⇒ SR/ST = SQ/SR = RQ/TR

⇒ SR/9 = 25/SR = x/TR

⇒ SR² = 25 × 9

⇒ SR = 5 × 3 = 15

SR² + RQ² = SQ²

RQ² = SQ² - SR²

RQ² = 25² - 15²

RQ = x = √(625 - 225)
