Given:

When the cardboard is folded to become a box (cuboid), it will have the following dimensions after the cut of squares from each corner;

The volume of a cuboid is given by;

Solve the quadratic equation by factorization;

Hence, the dimension of the original piece of cardboard is;

Therefore, the dimensions of the original piece of cardboard are 26 in by 22in

Explanation:

Length of green line = length of black line

Length of green line = 26

Total length of black line = h + h + *

Total length of black line = 2h + 8

Equate the two expressions

26 = 2h + 8

Collect the like terms

26 - 8 = 2h

18 = 2h

Isolate h by dividing both sides by 2

18/2 = 2h/2

h = 18/2

h = 9

The equation is 26 = 2h + 8

The term in the AP whose value is 201 / 2 is 71.3.

The first term of an arithmetic progression is 5 and the common difference is - 3/2.

The formula of the arithmetic progression can be described as follows:

nth term = a + (n - 1)d

where

Therefore, using the arithmetic progression formula,

a = 5

d = 3 / 2

nth term = 201 / 2

let's find the term(n)

Therefore,

- 201 / 2 = 5 + (n - 1) - 3 / 2

- 201 / 2 = 5  - 3 / 2 n  + 3 / 2

- 201 / 2  - 3 / 2 - 5 =  - 3 / 2 n

- 107  =  -3 / 2 n

The given data  is incorrect, k does not constitute a constant, but rather y does not varies directly to x.

We may have 11=7k for the initial point, implying that k=11/7.

Again for second point, we'd have 13=8k, which means k=13/8.

Using proportions, we can see that 11/7 doesn't really equal 13/8: cross multiply and you get 11*8=7*13, or 88=91.

Given the expression

We are asked to find the remainder. We can use the remainder theorem. This can be seen below.

According to this theorem, if we divide a polynomial P(x) by a factor ( x – a); that isn't essentially an element of the polynomial; you will find a smaller polynomial along with a remainder.

All we need to do is to substitute the value of (a) in the numerator to get the remainder. a is represented in the denominator.

Therefore, we will have;

Applying the Pythagorean Theorem, the ladder's height from the ground is: 24.3 ft.

If we know any two sides of a right triangle, the Pythagorean Theorem can be used to find the length of the third side, c, if c is the longest side, and a and b are the shorter sides of the right triangle, we ill have the equation:

c² = a² + b².

The ladder forms a right triangle with the wall of the building. Therefore:

Substitute

25² = 6² + b²

b = √(25² - 6²)

Answer:

Equation of line is given as y = mx + c, where m is the gradient and c is the y-intercept.

First find the gradient. Formula for gradient is given as (y2-y1)÷(x2-x1) or (y1-y2)÷(x1-x2).

Gradient = (2-0)÷(0-4) = -1/2

Equation of line is y = -1/2x + c

Substitute either one of the points into the equation to find c.

0 = -1/2(4) + c

c = 2

Hence, the equation of the line is y = -1/2x + 2.

Answer: The triangle is not possible.

Step-by-step explanation:

1) Find the missing angle

62+59+x=180

x=59

2) Use the Law of Sine to check if the triangle sides are the same.

The Law of sine means that Sine the angle and divide with the side across it will equal to same.

ANSWER

YES, the base is 4 ......option B

The first step is to simplify both sides of the equation. The equation can be written as

y^3 - 3^3 = 9y(y - 3)

For the left hand side, we would apply the difference of two cubes formula. it is expressed as

x^3 - y^3 = (x - y)(x^2 + xy + y^2)

By comparing with the left hand side of the equation,

x = y and y = 3. It becomes

(y - 3)(y^2 + 3y + 3^2)

= (y - 3)(y^2 + 3y + 9)

The equation becomes

(y - 3)(y^2 + 3y + 9) = 9y(y - 3)

If we divide both sides of the equation by (y - 3), it becomes

(y - 3)(y^2 + 3y + 9)/(y - 3 = 9y(y - 3)/(y - 3)

y^2 + 3y + 9 = 9y

y^2 + 3y - 9y + 9 = 0

y^2 - 6y + 9 = 0

We would solve the quadratic equation by applying the method of factorisation. We would find two terms such that their sum or difference is - 6y and their product is 9y^2. The terms are - 3y and - 3y. The equation becomes

y^2 - 3y - 3y + 9

y(y - 3) - 3( y - 3) = 0

(y - 3)(y - 3) = 0

y - 3 = 0 twice

y = 3 twice

Answer:

Step-by-step explanation:

[tex]5x-6y=30 \\ \\ 6y-5x=-30 \\ \\ 6y=5x-30 \\ \\ y=\frac{5}{6}x-5[/tex]

Perpendicular lines have negative reciprocal slopes, so the answer is -6/5.

Answer:

[tex]y=x-5[/tex]

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{4.4cm}\underline{Slope Formula}\\\\Slope $(m)=\dfrac{y_2-y_1}{x_2-x_1}$\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ \\are two points on the line.\\\end{minipage}}[/tex]

Given points:

Substitute the given points into the slope formula to find the slope of the line:

[tex]\implies m=\dfrac{-2-(-1)}{3-4}=\dfrac{-1}{-1}=1[/tex]

[tex]\boxed{\begin{minipage}{5cm}\underline{Point-slope Formula}\\\\$y-y_1=m(x-x_1)$\\\\where $m$ is the slope and\\ $(x_1,y_1)$ is a point on the line.\\\end{minipage}}[/tex]

Substitute the found slope and the point (4, -1) into the point-slope formula to create the equation of the line:

[tex]\implies y-(-1)=1(x-4)[/tex]

[tex]\implies y+1=x-4[/tex]

[tex]\implies y+1-1=x-4-1[/tex]

[tex]\implies y=x-5[/tex]

We will have the following:

First, we find the slope:

So, the equation that represents the line is:

So:

***Explanation***

We are given the points (-2, 1) & (2. 1).

From this we cans see that the line passes both times through y = 1.

We also know that the slope (m) is given by:

Now, we also know that the equation of the line in general form is given by:

So, the equation of the line will be given by:

So the function is a constant value, thus a horizontal line.

***Explanation for the general form of a line***

The general form of a line is given by:

Here "x" & "y" are two variables; "x1" & "y1" are the component of a point that belongs to that lline and "m" is the slope of that line. We remember that (x1, y1) can be any point that belongs to the line.

So, we simply replace the values, in our case I willl solve for (-2, 1), but we could also use (2, 1), the solution at the end will be the same.

Using simple interest, the rate of interest on the amount that Samantha borrowed to buy the law equipment is 11.75%.

A simple interest system does not accumulate (compound) interest on both the principal and interest, unlike compound interest.

The simple interest uses the following formula, Interest = Principal x Rate x Period.

This simple interest formula can be reversed to find either the principal, rate, or period, as the case may be.

The loan amount = $800

Period of loan  = 9 months

Total interest paid = $70.50

Rate of interest = (Interest × 100)/(Principal × Time)

= 11.75% ($70.50 x 100)/($800 x 9/12)

Check:

Interest = $70.50 ($800 x 11.75% x 9/12)

Thus, Samantha's interest rate on the loan is 11.75%.

What are Scientific notations?

Scientific notation is a way to display extremely big or extremely small numbers in a more understandable way. We are aware that full numbers can go on forever, but we are unable to write such enormous figures on paper. Additionally, a simpler method of representation was required for the numbers that appear at the millions place following the decimal. This makes it challenging to express a small number of integers in their enlarged form. We thus employ scientific notations. Learn general forms for numbers as well.

Rules for Scientific Notation

We must adhere to the following rule in order to calculate the power or exponent of 10:

The base must always be 10.

Exponents that are non-zero integers must be either positive or negative in order to be used.

The coefficient's absolute value is more than or equal to 1, but it must be less than 10.

Positive and negative numbers, including whole and decimal values, can be coefficients.

The remaining significant digits of the number are represented by the mantissa.

It means that, as can be seen in the figure, the length of every side of the right triangle can be calculated by multiplying its corresponding side in the left ("small") triangle by a constant. However, this can be done from the right triangle to the left triangle; that's why I put a bidirectional arrow.
