The value of the volume of this rectangular pyramid is,

⇒ V = 192 m³

We have to given that;

In rectangular pyramid,

Lenght = 8 m

Width = 9 m

Height = 8 m

Hence, The volume of this rectangular pyramid is,

⇒ V = 1/3 x Length x width x height

⇒ V = 1/3 × 8 × 9 × 8

⇒ V = 192 m³

Thus, The value of the volume of this rectangular pyramid is,

⇒ V = 192 m³

Answer:

m∠x = 47°

Step-by-step explanation:

The given shape is a triangle.

Sum of interior angles of the triangle is 180,

x + 102 + 31 = 180

x + 133 = 180

x = 180 - 133

m∠x = 47°

The required, difference between the perimeters of the two rectangles is,

⇒ 46.03 in.

Since, rectangles LMNP and WXYZ are similar, their corresponding sides are proportional. Let's denote the scale factor as k.

Then, We get:

k = XY / LM

k = 2.22 / 19

To find the value of k, we can divide 2.22 by 19:

k ≈ 0.117

Hence, The area of rectangle LMNP is given as,

140.6 in².

We can use this to find the length of NP:

LM x NP = area of LMNP

19 x NP = 140.6

NP ≈ 7.4 in

Since, the sides of WXYZ are proportional to those of LMNP, we can find the length of YZ:

XY / YZ = LM / NP

2.22 / YZ = 19 / 7.4

YZ ≈ 1.167 in

Now we can calculate the perimeters of both rectangles:

Perimeter of LMNP = 2(LM + NP) = 2(19 + 7.4) = 52.8 in

Perimeter of WXYZ = 2(XY + YZ) = 2(2.22 +1.167) = 6.77in

Thus, The difference between the perimeters is:

52.8 - 6.77 = 46.03 in

Answer:

  (2)  (-2, 4), (3, 9)

  (3)  (-2, 4), (1, 1)

Step-by-step explanation:

My favorite way to answer questions like this is to use a graphing calculator to find the points of intersection. The attached shows the points of interest.

If you want to solve this by hand, equate the expressions for y, then solve the resulting quadratic using any of the methods you know. Once you find the x-values, put those in either equation to find the y-value.

  (x -3)(x +2) = 0 . . . . factor

  x = 3 or -2 . . . . . find the x-values that make the factors zero

  y = x^2 = 9 or 4

The points are (3, 9) and (-2, 4).

  x = -2 or 1 . . . . . . .zeros

  y = x^2 = 4 or 1

The points are (-2, 4) and (1, 1).

Comment on factoring

When you consider the factored form and its expanded equivalent, ...

  (x +a)(x +b) = x^2 +(a+b)x +ab

you see that the coefficient of the linear term (a+b) is the sum of factors of the constant term (ab). Your knowledge of multiplication tables will often help you factor equations easily. You need to pay attention to signs.

In problem 2, we want factors of -6 that have a sum of -1:

  -6 = (-1)(6) = (-2)(3) = (-3)(2) = (-6)(1)

These factor pairs have sums of 5, 1, -1, -5. The pair whose sum is -1 is the one we're looking for: -3 and 2. So, the factors in problem 2 are (x-3)(x+2).

__

In problem 3, we want factors of -2 that have a sum of +1:

  -2 = (-1)(2) = (-2)(1)

These factor pairs have sums of 1, -1. So, the second pair is the one of interest: -2 and 1. That makes the factors be (x-2)(x+1).

Step-by-step explanation:

To solve, we need to figure out how many gallons of white paint she needs for every gallon of brown paint.

We are given this equation.

5 gallons of brown paint = 7 gallons of white paint

Divide both sides by 5.

1 gallon of brown paint = 7/5 gallons of white paint = 1.4 gallons of white paint

Now, using this, substitute 14 into the left side.

14 gallons of brown paint = 1.4 * 14 gallons of white paint

14 gallons of brown paint = 19.6 gallons of white paint

Thus, the answer is B, 19.6 gallons

the stable distribution for the given regular stochastic matrix is approximately:

π ≈ [0.5455, 0.2404, 0.2141]

How to solve?

To find the stable distribution for the regular stochastic matrix, we need to solve the equation:

πA = π

where π is the stable distribution and A is the transition matrix.

The given matrix is:

[0.4 0.2 0.6]

[0.8 0   0.2]

[0.1 0.9 0  ]

We can set up the equation as:

π[0.4 0.2 0.6] = π

π[0.8 0 0.2] π

π[0.1 0.9 0 ] π

Expanding this equation, we get:

π₁(0.4) + π₂(0.8) + π₃(0.1) = π₁

π₁(0.2) + π₃(0.9) = π₂

π₁(0.6) + π₂(0.2) = π₃

π₁ + π₂ + π₃ = 1

Simplifying and rearranging, we get:

0.4π₁ - 0.8π₂ + 0.1π₃ = 0

-0.2π₁ + 0.9π₃ - π₂ = 0

0.6π₁ + 0.2π₃ - π₃ = 0

π₁ + π₂ + π₃ = 1

We can solve this system of equations using matrix methods, such as Gaussian elimination or inverse matrices. Solving the equations, we get:

π₁ ≈ 0.5455

π₂ ≈ 0.2404

π₃ ≈ 0.2141

Therefore, the stable distribution for the given regular stochastic matrix is approximately:

π ≈ [0.5455, 0.2404, 0.2141]

x = 108

y = 111/5 = 22.2

========================================================

Explanation:

The angles 72 and x form a 180 degree straight line.

72+x = 180

x = 180-72

x = 108

Angles x and 5y-3 are congruent corresponding angles assuming the lines pointing to the northwest are parallel

5y - 3 = x

5y - 3 = 108

5y = 108+3

5y = 111

y = 111/5

y = 22.2

Answer:

x = 108°

y = 22.2°

Step-by-step explanation:

Angles on a straight line sum to 180°.

\(\implies 72^{\circ} + x = 180^{\circ}\)

\(\implies 72^{\circ} + x - 72^{\circ} = 180^{\circ} - 72^{\circ}\)

\(\implies x = 108^{\circ}\)

Corresponding Angles Theorem

When a straight line intersects two parallel straight lines, the angles in the same relative position are congruent.

Assuming the two lines that appear parallel in the given diagram are parallel:

\(\implies (5y - 3)^{\circ} = x^{\circ}\)

\(\implies 5y - 3 = 108\)

\(\implies 5y - 3 + 3 = 108 + 3\)

\(\implies 5y = 111\)

\(\implies 5y \div 5 = 111 \div 5\)

\(\implies y = 22.2^{\circ}\)

Algorithm 2 is more efficient than Algorithm 1 because it only needs to loop through the numbers up to upper/11 instead of upper. This means that it will take fewer iterations to reach the result, making it more efficient than Algorithm 1.

Algorithm 1 will make upper/11 more checks than Algorithm 2, resulting in a slower runtime. Additionally, Algorithm 2 avoids the need to check the modulus of each number, further reducing the computation time. Algorithm 2 only needs to loop through the multiples of 11, which are always 11 apart from each other, so it can skip over the other numbers between them.

This makes Algorithm 2 much faster than Algorithm 1 because it is only looping through a fraction of the numbers.
