Triangles PQR and ZQX are similar!

Square side => a

XZ / (PQ - PZ) = PR / PQ

a / (12 - a) = 8 / 12

a = 4.8

The side length of the square PZXY is sqrt(2).

A square is a two-dimensional figure that has four sides and all four sides are equal.

The area of a square is given as side².

We have,

Since triangle PQR is a right triangle, we can use the Pythagorean theorem to find the length of QR:

QR² = PQ² + PR²

QR² = 1² + 1²

QR² = 2

QR = √2

Since PZXY is a square, its sides are equal in length.

Let's denote the length of one side of the square as s.

Then, we can write:

PR = PX + RX

1 = s + QY

Since QY = PZ = s and PX = QX = QR - QY = sqrt(2) - s,

we can substitute these values into the equation for PR to get:

1 = s + (√2 - s)

1 = √2

Therefore,

The side length of the square PZXY is √2.

Therefore , the solution of the given problem of percentage comes out to be  19.9%  is the percent change.

In mathematics, a percentage is any value that can be written as a proportion of 100. There are also sporadic uses of the abbreviations "pct.," "pct," or "pc." However, it is commonly indicated by the "%" mark. The proportional amount is flat and lacks any dimensions. Since percentages have a numerator of 100, they can be thought of as fractions. The cent symbol (%) must come after a number to denote that it is a percentage.

Here,

Given:

You can compute 1.99 as a percent of a given number x by dividing 1.99 by x and multiplying the outcome by 100.

Answer:

Step-by-step explanation:

Given triangle WXY with sides WX = 7 in and XY = 7 in and angle X = 60°, you want the measure of angle Y and the length of side WY.

The equal given side measures tell you that their opposite angles (W and Y) have equal values. Those values will be such that the total of all angles is 180°:

  W +Y +X = 180°

  Y +Y +60° = 180° . . . . . . . . . . . use given values; substitute Y for W

  Y = (180° -60°)/2 = 60° . . . . . . . subtract 60°, divide by 2

All of the angles in this triangle have the same measure, so it is an equilateral triangle. All of the sides have the same measure, too.

  angle Y = 60°

  WY = 7 inches

Step-by-step explanation:

This is an example of a work-rate-time problem

Since the experienced roofer can finish the job in 24 hours, his rate of work would be 1/24 (of the roof) per hour

Let the time taken by the trainee alone be x hours

His rate of work = [tex]\dfrac{1}{x}[/tex]

Together they finish the roof in 15 hours
So combined work rate = [tex]\dfrac{1}{15}[/tex]

Since combined rate = sum of individual rates we get

[tex]\dfrac{1}{24} +\dfrac{1}{x} = \dfrac{1}{15}[/tex]

Move 1/24 to the right side:
[tex]\dfrac{1}{x} = \dfrac{1}{15} - \dfrac{1}{24}[/tex]

[tex]\dfrac{1}{x} =\dfrac{24 - 15}{24\cdot 15} = \dfrac{9}{360}\\\\[/tex]

A is directed along negative X and Y axes respectively having magnitudes 3.214 and 3.83 units respectively.

A vector is an object that, as we all know, possesses both magnitude and direction. We must determine a vector's length in order to determine its magnitude. Vector quantities include things like velocity, displacement, force, momentum, etc. However, scalar quantities like as speed, mass, distance, volume, temperature, etc. exist. In contrast to vectors, which

have both magnitude and direction, scalars only have magnitude.

Magnitude of vector A = |A| = 5 units

We know, the negative Y-axis is an angle of 270° counterclockwise with a positive X-axis.

θ = Angle of vector A with positive X-axis = (270° - 40°) = 230°

So, x component of vector A = Ax = |A| * cos 230° = |A| * cos (180° + 50°) = |A| * (- cos 50°) = 5 * (-0.6428) = -3.214

And, y component of vector A = Ay = |A| * sin 230° = |A| * sin (180° + 50°) = |A| * (- sin 50°) = 5 * (-0.766) = -3.83

Since Ax and Ay both are negative relative to positive X and Y axes respectively; so, the x and y components of vector A are directed along negative X and Y axes respectively having magnitudes 3.214 and 3.83 units respectively.

y = 3 cos(2 (x + π/2)) - 2

y = 3 cos(2x + π) - 2

Let θ = 2x + π,

Choice A.

Choice A is exponentially because the amount is double each day. In other words each day the amount gets larger. One day it increased by 10 cents, the next day 20 cents, the next day 40 cents and so on... eventually it'll be a day where it increases by a million cents.

Choice B is not exponentially, it is linearly because each day the amount increase stays the same. One day is $5.00 more, the next day it's $5.00 more, the next day it's $5.00 more... and so on.

Because of that, we can get rid of those two choice B options.

Both Choice A's look the same. The only difference is that one has a 2 and the other doesn't. That 2 indicates that we're doubling. Makes sense because that's what we associate with doubling.

The nontrivial solution to the equation Ax = 0 is x = [1, 1, 1]^T.

What is the nontrivial solution?

To find a nontrivial solution to the equation Ax = 0, where A is the given matrix, we need to find a vector x that satisfies the equation and is not the trivial solution x = 0.

We can start by using the observation that the first column plus twice the second column equal the third column:

4x1 - 7x2 + 9x3 = 0

x1 + 2x2 - 3x3 = 0

6x1 + 3x2 + 3x3 = 0

Applying row reduction to the matrix A, we find:

{{4,1,6},{-7,5,3},{9,-3,3}}

{{1,1/2,-3/2},{-7,5,3},{9,-3,3}}

{{1,1/2,-3/2},{0,11/2,15/2},{0,11/2,15/2}}

The rank of the matrix A is 2, which is less than the rank of the matrix of the system of linear equations, which is 3. This means there is a nontrivial solution to the equation Ax = 0.

One such nontrivial solution can be found by setting x3 = 1 and solving for x1 and x2:

x1 + 2x2 - 3(1) = 0

x1 + 2x2 = 3

x1 = 3 - 2x2

Setting x2 = 1, we find:

x1 = 3 - 2(1) = 1

x2 = 1

x3 = 1

Answer: The height of the stone after time "t" is given by the function h(t) = 100t - 5t^2, where t is in seconds. To find the maximum height, we need to find the value of t for which the height is greatest.

To do this, we can take the derivative of h(t) with respect to t, which gives us the rate of change of height with respect to time. Then, we can set this derivative equal to 0 and solve for t. The value of t that satisfies this condition will be the time at which the height is at its maximum.

h'(t) = 100 - 10t

Setting h'(t) = 0, we get:

100 - 10t = 0

10t = 100

t = 10

So, the maximum height is h(10) = 100 * 10 - 5 * 10^2 = 100 - 500 = -400 meters.

Since the height cannot be negative, the maximum height the stone can reach is 100 meters.

The functions and equations y = f(x) = 7·x³, x = 5, Δx = 0.06, indicates that we get;

a) Δy = 31.879512

b) dy = 21·x²dx

c) dy = 31.5

A function is a rule that maps input variables to output variables in a relationship in which an input is assigned to exactly one output.

a) The value of the function y = f(x) = 7·x³

The value of x = 5

Value of the change in x, Δx = 0.06

The change in y, Δy is therefore;

Δy = f(x + Δx) - f(x), from which we get;

Δy = f(5 + 0.06) - f(5) = f(5.06) - f(5)

Δy = f(5.06) - f(5)

Plugging in the values of x = 5.06, and x = 5 in the function f(x), we get;

f(5.06) = 7 × (5.06)³ = 906.879512

f(5) = 7 × 5³ = 875

Therefore; Δy = f(5.06) - f(5) = 906.879512 - 875 = 31.879512

Δy = 31.879512

b) dy = f'(x)dx

f'(x) is the derivative of the function f(x)

dy/dx = f'(x)  = 3 × 7 × x² = 21·x²

dy/dx = f'(x) = 21·x²

dy = f'(x)dx = 21·x²dx

dy = 21·x²dx

c) dy for the given x and Δx values can be found by plugging in x = 5 and dx = Δx = 0.06 in the equation, dy = 21·x²dx, as follows;
