The rules SSS SAS ASA and AAS are the rule that is used to prove the congruence of the triangle

The rules  SSS SAS ASA and AAS are used to prove the congruence of the triangles .

The congruence  means if shape and size of the one shape is same as the shape and size of the another shape, then we can say that both the shapes are congruent

If you consider the case of triangle, two triangle can be prove as congruent if the specifics sides and angles of the triangle is equal to the other triangles.

The rules that used to prove the congruence of the triangles are

SSS - side-side-side rule of congruence

SAS = side-angle-side rule of congruence

ASA = angle-side-angle rule of congruence

AAS = angle-angle-side rule of congruence

Therefore, these rules are used to prove the congruence of the triangle

Length and width should the rectangle have so that its area is a maximum are 4.242 and 2.121 respectively.

From the question, we have

Area = A = xy

A = xsqr(9-x^2)

Taking the derivative and set = 0

A' = (x/sqr(9-x^2)(-2x) + sqr(9-x^2) = 0

A' = -x^2 + 9 -x^2 = 0

-2x^2 =-9

x^2 = 9/2

x = 3/sqr2 = (3/2)sqr2 = 4.242

y = sqr(9-x^2) = sqr(9-9/2) = 3sqr2/2 = 2.121

Dimensions of the rectangle are 4.242 and 2.121 respectively

Multiplication:

Mathematicians use multiplication to calculate the product of two or more numbers. It is a fundamental operation in mathematics that is frequently utilized in everyday life. When we need to combine groups of similar sizes, we utilize multiplication. The fundamental concept of repeatedly adding the same number is represented by the process of multiplication. The results of multiplying two or more numbers are known as the product of those numbers, and the factors that are multiplied are referred to as the factors. Repeated addition of the same number is made easier by multiplying the numbers.

The point-slope form of the equation of Street D is; y = 0.8·(x - 5)

The point-slope of the equation of straight line can be expressed mathematically as (y - y₁) = m·(x - x₁)

The coordinates of the point

The x-intercept of the street D = 5

The y-intercept of the street D = -4

The x-intercept is the point the graph of the equation of the street intersects the x-axis.

At the x-intercept, the y-coordinate of the point of the graph is 0, therefore, the coordinate of the x-intercept is (5, 0)

The y-intercept is the point at which the graph of the function intersects the y-axis, therefore, the x-coordinate of the graph at the y-intercept is 0

The y-intercept of the street D is therefore; (0, -4)

The slope, m, of the equation of the street is therefore;

m = (-4 - 0)/(0 - 5) = 4/5 = 0.8

The point-slope form of the equation, using the x-intercept, (5, 0) is therefore;

The scalar equation of the plane that contains given points and lines can be written as: (-4)(x-1) + 4(y-2) + (-10)(z-3) = 0.

What is equation of plane?

A given point p(x, y, z) that is located on the plane and a normal vector n define the equation of a plane. A plane's vector and scalar components can be used to formulate the equation for the plane.

The parametric form of line equation,

[tex]p = p_0 + t. \vec v[/tex]

On comparing with the given equation in question, we can say that,

p = {x, y, z}, p₀ = {0, 6, 1,},  vec(v) = {3, -2, -2}

The scalar equation can be given by,

[tex][ \vec \omega, p - p_1] = 0[/tex]

Here, p₁ = {1, 2, 3} and ω is perpendicular to v and to the segment p₁ - p₀ So,

[tex]\vec \omega = \vec v \times (p_1 - p_0) = ( 3, -2, -2 ) \times (1, -4, -2)[/tex]

then,

[tex]\vec \omega = (-4, 4, -10)[/tex]

Therefore, the scalar equation can be written as:

(-4)(x-1) + 4(y-2) + (-10)(z-3) = 0

The required coordinates of the vertices of △ABC after it has been rotated 90 degrees, reflected across the line y=0, and then translated according to the rule (x+3,y-3) are A''' = [8, 1], B''' = [-3, -6], and C''' = [-5, -4].

To determine the coordinates of the vertices of △ABC after it has been rotated 90 degrees, reflected across the line y=0, and then translated according to the rule (x+3,y-3), we need to apply these transformations to the coordinates of the original vertices in the order given.

First, we rotate the triangle 90 degrees counterclockwise around the origin. This transformation can be represented by the matrix:[cos(90) -sin(90)][sin(90) cos(90)]

Applying this matrix to the coordinates of the vertices of △ABC, we get:A' = [-5, 4]B' = [6, -3]C' = [8, -1]

Next, we reflect the triangle across the line y=0.

This transformation can be represented by the matrix:[-1 0][0 1]

Applying this matrix to the coordinates of the vertices of △ABC', we get:A'' = [5, 4]B'' = [-6, -3]C'' = [-8, -1]

Finally, we translate the triangle according to the rule (x+3,y-3).

This transformation can be represented by the matrix:[1 0][0 1]

Applying this matrix to the coordinates of the vertices of △ABC'', we get:A''' = [8, 1]B''' = [-3, -6]C''' = [-5, -4]

Therefore, the coordinates of the vertices of △ABC after given transformations are A''' = [8, 1], B''' = [-3, -6], and C''' = [-5, -4].

Given that the hoop makes one complete oscillation in 2s, this implies that the period of oscillation is 2s

Then,

T = 2s

Let the Mass of the thin hoop be M

Let the Radius of the hoop be R

The moment of inertial of a hoop is

I = MR²

The period of a physical pendulum of small amplitude is given by

T = 2π √(I / Mgd)

Where,

T is the period in seconds

I is the moment of inertia in kgm²

M is the mass of the hoop

g is the acceleration due to gravity

g = 9.8m/s²

d is the distance from the rotational axis to the center of gravity

Therefore, d = R

Then, applying the formula

T = 2π √ (I / MgR)

So, we know that

I = MR²

Then,

T = 2π √( MR² / MgR)

T = 2π √(R/g)

Make R the subject of the formula

Square both sides

T² = 4π²(R/g)

T²g = 4π²R

Then, R = T²g / 4 π²

Since g = 9.8m/s² and T= 2s

R = 2² × 9.8 / 4π²

R = 0.993m

Then, the radius of the hoop is 0.993m

The height of the top section of the tower is 32 feet.

The radio station tower is built in two sections. The tower is 87 feet from the viewing point. The angle of elevation of the bottom section is 25 degrees. The angle of elevation from the top of tower (both sections) is 40 degrees. Let the height of the bottom section be y and height of the bottom and top section be z.

Considering a right-angled triangle, tangent formula states that:

Tan ɵ = opposite side/ adjacent side where ɵ is the angle of elevation.

Hence, when ɵ = 25, opposite side = y, and adjacent side = 87

Tan 25 = y/ 87

y = 40.57 feet

Hence, when ɵ = 40, opposite side = z, and adjacent side = 87

Tan 40 = z/87

y = 73 feet

Let the height of the top section of the tower be x.

The slope of Line P Q is (v - z) divided by (w - x). The slope of Line P prime Q prime is

(v + b) - (z +b) divided by (w + a) - (x + a). Both lines have a slope that is (v - z) divided by (w - x). Therefore, the lines are parallel.

Slope of line :

Line slope is a measure of the slope and direction of a line. Finding the slope of a line in the coordinate plane helps predict whether the line is parallel or perpendicular without actually using a compass. The slope of a line is defined as the change in y-coordinate with respect to the change in x-coordinate of the line.

The formula for the slope is

m = (y₂ - y₁)/ (x₂ - x₁)

Where (x₁, y₁) and (x₂, y₂) are the points

We have given a line PQ passing through points (x,z ) and (w,v) then slope of line is

m = ( v- z)/(w-x) --(1)

that is line lie in XZ- plane .

The slope of line p prime and q prime

m' = (( v- b) - (z-b))/(w-a)- (x-a)

= (v -b -z + b) /(w-a -x + a)

= (v-z)/(w-x) --(2)

The population standard deviation of the data is gotten from using the sum of squares and count which gave us 1.5

Standard deviation is used to find the values of a particular data that is dispersed or scattered. Standard deviation can be defined as the deviation of the values or data from an average mean. Lower standard deviation assumes that the values are very close to their average. Meanwhile higher values mean the values are far from the mean value. Note that the value of standard deviation value can never be negative.

The data given is

5, 8, 8, 5

The formula is given as

δ = √(μ / n)

δ = √(9/4)

The computation of the peanuts in the hands of Alex can easily be ascertained using the given information, and input of values from the same into the generalized formula, as shown below,

Let p be the number of peanuts. Thus, it can be stated that
