What is arithmetic progression ?When there are identical differences between every two next words, the series is known as an arithmetic progression (AP). There is a chance to find a formula for the nth term of the AP using this kind of development. The series 2, 6, 10, 14, etc., for instance, is an example of an arithmetic progression (AP) because it follows a pattern in which each number is acquired by adding 4 to the preceding word. Nth term in this series equals 4n-2.
Given that :Lerato begins a new cycling programme with 2 km on the first day. Each day, he will increase his cycling by 500 m.
The formula to find Sum of an arithmetic progression is

a wood cutter has 1/4 + 2/4 + 3/4 of wood And goes to the store and buys 1/4 + 2/4 + 3/4 And adds all of his wood up.
Answer: I believe the answer is 3.
Step-by-step explanation:
a wood cutter has 1/4 + 2/4 + 3/4 So we add those up to get 6/4.
Then he buys the same amount again which would make 12/4.
We are not done probably, so we MUST simplify.
how many times can 4 fit into 12? 3! so we have whole number 3 and since 4 fit into 12 3 times perfectly all we have is 3

We are to solve using completing the square:
1/4x² + x + 1/4 = 0
Let's collect like terms:
1/4x² + x = -1/4
Divide both sides by the coefficient of x-squared:
x² + 4x = -1
Take half of the coefficient of x, square it, then add to both sides:
x² + 4x + 4 = -1 + 4
factor the left side of the equation:
(x + 2)² = 3
Take the root of both sides;
x + 2 = ±√3
Add 2 to both sides:
x = ±√(3) - 2
x = -2 + √3 or x = -2 - √3
herefore, the correct option is B, which is x = -2 + √3 or x = -2 - √3

The width of a rectangle is fixed at 5 cm. Determine (in terms of an inequality) those lengths for which the area will be less than 125 cm2.
The lengths of the rectangle for which the area will be less than 125 cm² is 5 < m < 25
In this question, we have been given the width of a rectangle is fixed at 5 cm.
We need to determine (in terms of an inequality) those lengths for which the area will be less than 125 cm²
Let 'm' be the length of the rectangle.
The area of the rectangle is:
A = length × width
The area of the rectangle should be less than 125 cm²
5 × m < 125
Divide both the sides of the inequality by 5
m < 25
This means, the length of rectangle should be less than 25 cm
But length is always greater than the width of the rectangle.
So, we get an inequality 5 < m < 25
Therefore, the lengths of the rectangle for which the area will be less than 125 cm² is 5 < m < 25

In a recent year, 26% of all college students were enrolled part-time. If 4.4 million college students were enrolled part-time that year, what was the total number of college students? Round your answer to the nearest million.
Answer: 17 million
Step-by-step explanation:
We will set up a proportion to solve. We also will divide 26% by 100 to get a decimal, 0.26. We know that 26% of college students was 4.4 million, but we want to find 100%.
[tex]\displaystyle \frac{0.26}{4.4\text{ million}} =\frac{1}{x\text{ million}}[/tex]
Now, we will cross-multiply.
0.26 * x = 1 * 4.4
0.26x = 4.4
Lastly, we will divide both sides of the equation by 0.26. Then, we will round to the nearest million.

Answer:

Step-by-step explanation:
Let n be the unknown number.
The quotient is the result obtained by dividing one number by another.
Therefore, the quotient of a number and 8 is ⁿ/₈.
If the quotient of a number and 8 is added to 1/4 the result is 7/8:
[tex]\implies \dfrac{n}{8}+\dfrac{1}{4}=\dfrac{7}{8}[/tex]
To solve, make the denominators of all the fractions the same:
[tex]\implies \dfrac{n}{8}+\dfrac{1 \cdot 2}{4 \cdot 2}=\dfrac{7}{8}[/tex]
[tex]\implies \dfrac{n}{8}+\dfrac{2}{8}=\dfrac{7}{8}[/tex]
[tex]\textsf{Apply the fraction rule} \quad \dfrac{a}{c}+\dfrac{b}{c}=\dfrac{a+b}{c}:[/tex]

Multiply both sides by 8:
[tex]\implies \dfrac{8(n+2)}{8}=\dfrac{7 \cdot 8}{8}[/tex]

THE GILBERTS PURCHASED A CAR. IF THE TOTAL COST, INCLUDING A 5% SALES TAX, WAS $14,512, FIND THE COST OF THE CAR BEFORE TAX
The cost of the car the Gilberts purchased before tax is $13,820.52.
What is the cost before tax?Tax is a compulsory amount that is levied on a good or service by the government. A sales tax is a tax that is levied on the purchase of a good and service. Taxes increase the cost of a good or service.
The equation that can be used to determine the cost of the car after tax is:
(1 + sales tax) x cost before tax = cost after tax
(1 + 0.05) x c = $14,512
1.05c = $14,512
In order to determine the value of c, divide both sides of the equation by 1.05:

x = 14*15/21 x = 10Factor the trinomials:
1) [tex]x^2 -2x-2[/tex]
2)[tex]x^2-6x+4[/tex]
Given that equation
1) [tex]x^{2} - 2x - 2[/tex] using the general quadratic equation, x = 1
2)[tex]x^{2} -6x -4[/tex] using the general quadratic equation, x= [tex]\frac{6 - \sqrt{20} }{2}[/tex]
According to the question, given that
1) [tex]x^{2} - 2x - 2[/tex]
2)[tex]x^{2} -6x -4[/tex]
this equation cannot be factored but using general quadratic equation. we solved it easily.
When asked to solve a quadratic equation that you just can’t seem to factor (or that just doesn’t factor), you have to employ other ways of solving the equation, such as by using the quadratic formula. The quadratic formula is the formula used to solve for the variable in a quadratic equation in standard form.
Given a quadratic equation in standard form ax2 + bx + c = 0,
[tex]x = \frac{- b - \sqrt{b^{2} - 4 ac } }{2a}[/tex] and [tex]x = \frac{- b + \sqrt{b^{2} - 4 ac } }{2a}[/tex]
solve [tex]x^{2} - 2x - 2[/tex] = 0, you first say that a = 1, b = –2, and c = 2. The a, b, and c terms simply plug into the formula to give you the values for x:
1) [tex]x^{2} - 2x - 2[/tex]
[tex]x = \frac{- (-2) + \sqrt{(-2)^{2} - 4 (1)(1) } }{2(1)}[/tex]
[tex]x = \frac{2 + \sqrt{4 -4} }{2}[/tex]
x = [tex]\frac{2}{2}[/tex]
[tex]x = 1[/tex]
and [tex]x = \frac{- (-2) - \sqrt{(-2)^{2} - 4 (1)(1) } }{2(1)}[/tex]
[tex]x = \frac{2 - \sqrt{4 -4} }{2}[/tex]
x = [tex]\frac{2}{2}[/tex]
[tex]x = 1[/tex]
equation [tex]x^{2} - 2x - 2[/tex] and x= 1
2)[tex]x^{2} -6x -4[/tex]
solve [tex]x^{2} - 6x - 4[/tex] = 0, you first say that a = 1, b = –6, and c = 4. The a, b, and c terms simply plug into the formula to give you the values for x:
[tex]x^{2} -6x -4[/tex]
[tex]x = \frac{- (-6) + \sqrt{(-6)^{2} - 4 (1)( 4) } }{2(1)}[/tex]
[tex]x = \frac{6 + \sqrt{36 - 16} }{2}[/tex]
x = [tex]\frac{6 \sqrt{20} }{2}[/tex]
and [tex]x = \frac{- (-6) - \sqrt{(-6)^{2} - 4 (1)(4) } }{2(1)}[/tex]
[tex]x = \frac{6 - \sqrt{36 - 16} }{2}[/tex]
x = [tex]\frac{6 - \sqrt{20} }{2}[/tex]
equation [tex]x^{2} - 6x + 4[/tex] and x= [tex]\frac{6 - \sqrt{20} }{2}[/tex]
