the equation straight line y = -1/5 x + 4. of the line drawn in the picture is attached below.

What is equation straight line?

There are numerous ways to express the equation of a straight line, including point-slope form, slope-intercept form, general form, standard form, etc. A straight line is a geometric object with two dimensions and infinite lengths at both ends. The formulas for the equation of a straight line that are most frequently employed are y = mx + c and axe + by = c. Other versions include point-slope, slope-intercept, standard, general, and others.

Given two line-side coordinates, use the slope formula to determine the slope of the line. The slope is defined as the ratio of the change in the y values to the change in the x values using the formula m=(y2-y1)/(x2-x1).

The given equation y = -1/5 x + 4.

Here m = -1/5

and c= 4

So the plot on the graph will be as fallow.

Hence the equation of the line drawn in the picture attached below

Remove any grouping symbol such as brackets and parentheses by multiplying factors.

Use the exponent rule to remove grouping if the terms are containing exponents.

Combine the like terms by addition or subtraction

Combine the constants

Simplify 3x2 + 5x2

Solution

Since both terms in the expression are have same exponents, we combine them;

3x2 + 5x2 = (3 + 5) x2 = 8x2

A square and a rectangle have the same perimeter, then the area of the square and the rectangle are the same.

An object's area is how much space it takes up in two dimensions. It is the measurement of the amount of unit squares which completely encompass the surface of a compact figure. The squared unit, which is frequently expressed as inches, square feet, etc., is the accepted unit of area.

Let x be the side of the square,

The length of the rectangle, l = 2x - 4,

The width of the rectangle, w = x - 6,

So, we have: (2x - 4) × (x -6) = x²,

x = 2 (4 + √10)

= 14.32455 cm, it is the side of the square

14.32455 × 2 -4

=24.6491cm, it is the length of the rectangle.

14.32455 - 6

=8.32455cm, it is the width of the rectangle.

24.6481 × 8.32455 = 14.32455²

= 205.19 cm²

Thus, it means that the areas of square and rectangles are similar.

When the ball is punted the value of x is zero, therefore f(0) is:

Answer:

1.5 feet

Step-by-step explanation:

Given function,

→ f(x) = (-16/1225)x² + (7/5)x + 1.5

Required function,

→ f(x) = f(0)

→ f(0) = (-16/1225)x² + (7/5)x + 1.5

Now the needed height is,

→ (-16/1225)x² + (7/5)x + 1.5

→ (-16/1225)(0)² + (7/5)(0) + 1.5

→ 0 + 0 + 1.5

→ 1.5 feet

Hence, the height is 1.5 feet.

The value of t in the equation can be express as follows:

[tex]t = \frac{V-7\pi r^{2} }{6\pi r}[/tex]

The subject of a formula is the variable that is being worked out. The subject of a formula is the variable which is expressed in terms of the other variables.

The variable to be worked out is t.

Therefore,

V = 6πrt + 7πr²

Therefore, let's make t the subject of the formula,

V = 6πrt + 7πr²

subtract 7πr² from both sides of the equation.

V = 6πrt + 7πr²

V - 7πr² = 6πrt + 7πr² -7πr²

V - 7πr² = 6πrt

divide both sides of the equation by 6πr

Hence,

[tex]\frac{V-7\pi r^{2} }{6\pi r}=t[/tex]

Therefore,

[tex]t = \frac{V-7\pi r^{2} }{6\pi r}[/tex]

Matrix A is invertible such that A⁻¹ = - A - 3I. This is solved using the Calely Hamilton Theorem.

This theorem says that every square matrix satisfies its own characteristic equation. In other words, the scalar polynomial

p(λ) = det(λI − σ) also holds for the stress polynomial p(σ).

It also states that The roots λ₁, λ₂........λₙ of a typical equation (aₙλₙ + aₙ₋₁ λⁿ⁻¹ + ...... a₁ λ + a₀)  will indicate the nature of the Matrix A. If either of the roots of the attributes equation is 0, the matrix's determinant becomes zero. As a result, the matrix is non-invertible.

Based on the above, we know that Matrix A fulfills the qualities below::

A²+3A + I = 0

Since every square matrix fulfills its own characteristic

λ₁ + λ₂ = -3

λ₁ x λ₂ = 1 ≠ 0

This is true for any order of a square matrix. That is:
λ₁ x λ₂ x λ₃ x........ x λₙ ≠ 0

Thus

|A| = λ₁ x λ₂ x λ₃ x........ x λₙ

|A| ≠ 0 → Invertibel Matrix

A² + 3A + I = 0
I = -A² - 3A
A⁻¹ x I = A⁻¹ (-A - 3A); hence

A⁻¹ = - A - 3I

The value of test statistic t is -2.39 and P-value is P(t₈< -2.39).

The mean and the standard deviation can be calculated from the below formulae:

Sample mean (X)= (∑xi)/n

Sample standard deviation (s)= √(∑xi- X)²/(n-1)

where, n is sample size = 9

xi= elements in sample

On calculation we get X as,

X = (3.5+6.5+6.5+5.5+19.5+7+12.5+20+10.5)/9 = 10.17

s = √(∑xi- X)²/(n-1)

= √(44.49+13.47+13.47+21.81+87.05+10.05+5.43+96.63+0.11)/8

= √36.57 = 6.04

t would represent the static, it is given by the formula,

t = (X-μ₀)/(s/√n)

where μ₀ = 15 from the data (the value we want to test)

t = (X-μ₀)/(s/√n) = (10.17-15)/(6.04/√9) = -2.39

Step-by-step explanation:

You want to know the number of roots of x^3+4x^2-9x-36.

The degree of the given polynomial is the highest exponent of x: 3. That is the number of roots the polynomial has.

There are 3 roots.

The number of sign changes among the coefficients tells you the number of positive real roots. The signs go from + to - one time, so there is one positive real root.

When the signs of odd-degree terms are switched, the signs become ...

  - + + -

There are two sign changes here, meaning that there may be 2 or 0 negative real roots. (If there are 0 real roots, the two roots are complex.)

You can see that successive pairs of terms have coefficients with the same ratio. That means you can factor this by grouping terms:

  x^3+4x^2-9x-36

  = (x^3+4x^2) -(9x+36)

  = x^2(x +4) -9(x +4)

  = (x^2 -9)(x +4)

  = (x -3)(x +3)(x +4) . . . . . roots -4, -3, and +3

The perimeter of triangle ABC = 60 + 20√3  cm

What is perimeter?

The complete length of a shape's edge serves as its perimeter in geometric terms. Adding the lengths of all the sides and edges that surround a form yields its perimeter. It is calculated using linear length units such centimeters, meters, inches, and feet.

In triangle ADB,

sin (30°) = AD/AB

1/2 = ( 10 √3 ) /AB

AB  = 20√3

In triangle ABC,

cos (30°) = AB/BC

√3 /2 =  20√3 / BC

BC = 40

tan (30°) = AC/AB

1/√3 =  AC/ 20√3

AC = 20

Perimeter of triangle ABC =  AB +BC  + AC

                                           = 20√3  +  40  + 20

                                           = 60 + 20√3

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant.

A linear equation must have the highest power of the independent variable as 1.

option A and C, the independent variable x has degree 2

option D the x variable there stands for absolute values.
