What do you mean by simple interest and compound interest?
Simple interest can be defined as the amount that is paid back using borrowed money over a period of time.
simple interest:
Simple interest can be defined as the principal of a loan or deposit that an individual puts into a bank account.
Compound interest:
Compound interest is interest that accrues on the principal and accrues interest.
Given:
Principal, P = $710000
Rate of interest, r = 8.25%
Time period, t = 20 years
withdrawal at the end of 20 years , A = [tex]P(1+r)^{t}[/tex]
A = [tex]710000(1+8.25/100)^{20}[/tex] = [tex]710000(1+0.0825)^{20}=710000(1.0825)^{20}[/tex]

use the formula for the area of the circle and the dimensions you listed in level 5 to explain the formula for the area of a circle (r2).
The formula for the area of a circle is given as follows:
A = πr².
How to obtain the area of a circle?The area of a circle of radius r is given by the multiplication of the number π and the square of the radius, according to the equation presented as follows:
A = πr².
Hence, for example, for a circle of radius of 5 units, the area is given as follows:
A = π x (5 units)² = 25π units².
The diameter of a circle is twice the radius, hence the radius is half the diameter, and as a function of the diameter, the area will be given as follows:
A = 0.25πd².
As the diameter in the context of this problem is:
r² = (0.5d)² = 0.25d².
Missing InformationThe problem is incomplete, hence the area of the circle was explained in general terms.

Write a linear equation that passes through
the points (-3, 3) and (9, -13).
In Point - Slope form.
The point slope form of equation is y- 3 = -4/3( x- (-3)).
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx
where, m is the slope
Given:
Points= (-3, 3) and (9, -13)
Now,
slope= (-13 - 3)/ (9 - (-3))
slope= -16 / 12
slope= -4/3
Now, the point slope form
y- [tex]y_1[/tex] = m (x- [tex]x_1[/tex])
y- 3 = -4/3( x- (-3))
y- 3= -4/3x - 4
y= -4/3x - 1
Hence, the point slope for of equation is y- 3 = -4/3( x- (-3)).

Calculate the rate of change of function f(x)= sqaure root of x - 1/square root of x
The rate of change of function [tex]f(x) = \sqrt{x} - \frac{1}{\sqrt{x}}[/tex] for x = 4 and x = 9 is 7 / 30.
We know that the rate of change of a function is nothing but the slope of the line.
The slope of the line is given by;
Slope = Change in y-coordinate / change in x-coordinate
We are given;
[tex]f(x) = \sqrt{x} - \frac{1}{\sqrt{x}}[/tex]
We need to find the rate of change of function for x = 4 and x = 9.
Let us find the value of y or f(x) for the given value of x.
For x = 4, [tex]f(x) = \sqrt{4} - \frac{1}{\sqrt{4}}[/tex] = 2 - 1/2 = 4 - 1 / 2 = 3 / 2
For x = 9, [tex]f(x) = \sqrt{9} - \frac{1}{\sqrt{9}}[/tex] = 3 - 1/3 = 9 - 1 / 3 = 8 / 3
Put the values of x and y in the slope formula, we will get;
Slope = (8 / 3 - 3 / 2) / (9 - 4) = 7 / 6*5 = 7 / 30
So, the rate of change of function is 7 / 30.
Thus, the rate of change of function [tex]f(x) = \sqrt{x} - \frac{1}{\sqrt{x}}[/tex] for x = 4 and x = 9 is 7 / 30.

The value of ∠A in triangle ABC is 40°
What is a triangle?A triangle is a geometric figure with three edges, three angles and three vertices. It is a basic figure in geometry.
The sum of the angles of a triangle is always 180°
In the given triangle ABC,

By alternate segment theorem,
∠C=4x+27°
The sum of all the angle of a triangle is 180°.
∠A+∠B+∠C=180°
⇒7x-16+81+4x+27=180

What is the equation of this graph the line?
The slope-intercept form of the given line be,
y = -(9/8)x + 7
Given, a line is passing from two points (0 , 7) and (8 , -2)
we have to find the slope-intercept form of the equation of the line passing from the given points.
Using the slope-intercept form, we get
(y - y1)/(x - x1) = (y1 - y2)/(x1 - x2)
(y - 7)/(x - 0) = (7 - (-2))/(0 - 8)
(y - 7)/(x - 0) = 9/-8
-8(y - 7) = 9x
-8y + 56 = 9x
9x + 8y = 56
Slope-intercept form of the equation is,
y = -(9/8)x + 7

What is the smallest distance between the origin and a point on the graph of y = 1/2*(x^2 - 8)?
The smallest distance between the origin and a point on the graph of y = 1/2(x² - 8) is √7 units.
Given, a function
y = 1/2(x² - 8)
We have to find the smallest distance between origin and a point on the graph of y = 1/2(x² - 8).
Now, the point on the graph be,
( x , 1/2(x² - 8) ) and origin be (0 , 0)
Let the function of the distance between both the points be,
D = √(x - 0)² + (1/2(x² - 8) - 0)²
D = √x² + 1/4(x² - 8)²
D² = x² + 1/4(x² - 8)²
On differentiating, we get
2DD' = 2x + x(x² - 8)
x³ + 2x - 8x = 0
x³ - 6x = 0
x(x² - 6) = 0
So, x = 0 , √6 , -√6
and the distance is minimum for x = √6
Therefore, using distance formula, we get
Distance = √(x1 - x2)² + (y1 - y2)²
Distance = √(0 - √6)² + (0 - (-1))²
Distance = √6 + 1
So, the smallest distance between the origin and a point on the graph of y = 1/2(x² - 8) is √7 units.
Hence, the smallest distance between the origin and a point on the graph of y = 1/2(x² - 8) is √7 units.
