Repeat the procedure of dividing, multiplying, subtracting, and bringing the next digit down until you have solved the division problem's quotient.
For example, consider the long-division problem:
4567 ÷ 123
In this problem, we need to repeat the process of dividing, multiplying, subtracting, and bringing the next digit down three times, since the divisor has three digits.
However, in some cases, you may need to repeat the process more or fewer times than the number of digits in the divisor.
For example, if the dividend has fewer digits than the divisor, you may need to repeat the process fewer times. Or, if you need to carry a digit over to the next step, you may need to repeat the process more times.
Thus, in general, you should repeat the process of dividing, multiplying, subtracting, and bringing the next digit down until you have found the quotient of the division problem. This will typically be the number of digits in the divisor, minus one, but it may be more or fewer in some cases.

How do you find the vertical and horizontal asymptotes of a function using limits?
Consider the behavior of the function when x approaches the value of the vertical asymptote from the left and from the right in order to locate the vertical asymptotes of a function using limits. Consider the behavior of the function when x grows very big in order to determine the horizontal asymptotes of a function using limits (in either the positive or negative direction).Similary, To find the horizontal asymptotes of a function using limits, consider the behavior of the function as x becomes very large (in either the positive or negative direction). If the y-values of the function approach a fixed value as x becomes very large, then that value is the horizontal asymptote of the function.
what is an Asymptote?An asymtote is a line being approached by a curve but never touching the curve at any finite distance.It is a line that the graph approaches as either x or y in positive or negative infinity.
What is vertical asymptote?A vertical line that directs the function's graph but is not actually a part of it is called a vertical asymptote. Because it appears at an x-value outside of the function's scope, the graph can never cross it. There may be several vertical asymptotes for a given function.
Consider the behavior of the function when x approaches the value of the vertical asymptote from the left and from the right in order to identify the vertical asymptotes of a function using limits. The vertical asymptote is at that value of x if the function approaches positive infinity as x approaches the asymptote from the left and negative infinity as x approaches the asymptote from the right. Consider the function f(x) = 1/x as an illustration. We may take into account how the function behaves as x approaches 0 from the left and from the right in order to determine the vertical asymptotes of this function using limits.The y-values of the function become closer to negative infinity as x moves toward 0 from the left (negative x-values). The y-values of the function get closer to positive infinity as x gets closer to 0 from the right (positive x-values). As a result, we may infer that the function's vertical asymptote lies at x = 0.
Similary, Consider the behavior of the function when x grows very big in order to determine the horizontal asymptotes of a function using limits (in either the positive or negative direction). The horizontal asymptote of the function is the point at which the y-values of the function begin to approach a fixed value when x increases significantly.

(b) ∠BCD = 60°
(c) ∠ADC = 105°
What is a composite figure?A composite figure is a figure comprising of two or more regular geometric figures.
9. The shape of the quadrilateral ABDE = A square
The kind of triangle specified for the triangle ΔBCD = Equilateral triangle
The sides of the square ABDE are congruent by the definition of a square
Therefore; AB = BD = DE = AE by the definition of congruency
(a) Angle ∠ABD is a corner of the square ABDE, therefore;
The size of angle ∠ABD = 90° (properties of the interior angle of a square)
∠ABD = 90°(b) The size of angle ∠BCD = 60° (Interior angle of an equilateral triangle)
∠BCD = 60°(c) The size of angle ∠ADC is found as follows;
Triangles ΔAED and triangle ΔABD formed by the diagonal AD are congruent by Side-Side-Side, SSS congruency postulate
∠DAB ≅ ∠ADB (base angles of isosceles triangle ΔABD)
∠DAB = ∠ADB (Definition of isosceles triangles)
∠ABD + ∠DAB + ∠ADB = 180° (Angle sum properties of a triangle)
90° + 2 × ∠ADB = 180° (substitution property)
∠ADB = (180° - 90°) ÷ 2 = 45°
∠BDC = 60° (Interior angle of an equilateral triangle)
∠ADC = ∠ADB + ∠BDC (Angle addition postulate)
Therefore, ∠ADC = 45° + 60° = 105°

Yoezer bought 25 shares that had a face value of Nu 100 but were selling at a discount of 5%. A 15% dividend rate was paid at the end of one year. He then sold the stock at a 5% premium.
i. Find the amount of his investment.
ii.Calculate his total profit.
2375 is the amount of his investment and 625 is his total profit
The discount on the shares is 5%, so the price of each share is 100 - (5/100)100 = 95.
The total price Yoezer paid for the shares is 2595 = 2375.
To calculate Yoezer's total profit, we need to find the total dividend he received and the price he sold the shares for.
The dividend rate is 15%, so Yoezer received a dividend of (15/100)100 = 15 on each share.
The total dividend he received is 1525 = 375.
The price Yoezer sold the shares for was increased by a premium of 5%, so the selling price was 100 + (5/100)100 = 105.
The total selling price for the shares is 10525 = 2625.
Yoezer's total profit is the selling price minus the price he paid for the shares plus the dividends he received. This is 2625 - 2375 + 375 = 625.

Answer:
There is no real square root of -4 because it is impossible to square any real number and get a negative answer.
You might think -2 could work. However, a negative times a negative is positive → -2(-2) = +4, so the problem would have to be written as [tex]\sqrt4[/tex] instead of [tex]\sqrt{-4}[/tex]. Hence, there is no real square root of -4.

define the derivative of a funnction y = f(x) at the point a
Answer:
Step-by-step explanation:
The derivative of a function y = f(x) at the point a is a measure of the rate of change of the function at that point. It is represented by the symbol f'(a) or df/dx.
The derivative can be thought of as the slope of the tangent line to the curve of the function at the point a. It is calculated using the limit definition of the derivative, which states that the derivative of a function at a point is the limit of the difference quotient as the difference between x and a approaches zero.
In other words, the derivative of a function y = f(x) at the point a is the slope of the line that is tangent to the function at that point, and it is calculated using the following formula:
f'(a) = lim(h -> 0) [(f(a+h) - f(a)) / h]
This formula can be used to calculate the derivative of any function at any point. I hope this helps! Let me know if you have any questions.
