The   BEST advice you can offer so that he can maximize interest is : b Deposit your money as early as possible in an account with the highest interest rate possible.

Compound interest can be defined as the interest a person earn on the money they saved in their account as well as the money earn on the interest the bank gives them which implies that a person tend to earn interest on the money saved and the interest giving on the money saved.

A person can tend to earn more interest when they deposit their money earlier into an account that pay more interest rate as this will enables them to accumulate more interest.

Therefore the correct option is b.

The expression 1/(2x²) - 7y is not a polynomial because it has a negative exponent

An equation is an expression that shows the relationship between two or more numbers and variables.

Equations are classified based on degree (value of highest exponents) as linear, quadratic, cubic and so on. Variables can be dependent or independent. Dependent variables depend on other variable while an independent variable do not depend.

A polynomial is an expression that involves only the operations of addition, subtraction, multiplication, and positive exponent powers of variables. If the expression has a negative exponent, it is not a polynomial.

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx + c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If [tex]\theta[/tex] is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m = [tex]tan\theta[/tex]

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.

Here,

x intercept = 0 and y intercept = 0

This means that  if Ryan do not work at all, he will not be paid.

The surface area of the given pyramid is equivalent to 760 square inches.

The surface area of a figure is the sum of the area of the surfaces of such figure.

The given pyramid is made up of 5 big rectangles and 2 small rectangles

Surface area = Area of 4 large rectangles + 2(area of small rectangles)

Surface area = 2(22 * 10) + 2(22 * 5) + 2(10 * 5)

Surface area = 440 + 220 + 100

Surface area  = 760 square inches

The perimeter of each pool is 92 ft.

What is perimeter?

A perimeter is a closed route that covers, surrounds, or outlines a two-dimensional form or length. The circumference of a circle or an ellipse is its perimeter.

Given, the triangles are congruent so,

20x-15 = 15x+15

=> 20x-15x = 15+15

=> 5x = 30

=> x = 30/5 = 6

Therefore, perimeter = (4x-4) + (5x+1) + 41

                                    = (4x6 - 4) + (5x6 + 1) + 41

                                    = 20 + 31 + 41

                                    = 92

Hence, the perimeter of each pool is 92 ft.

The measure of an exterior angle of a regular octagon is 45 degrees

Angles are formed when two or more lines intersect.

This in other words means that angles is the measure of space between the intersection of rays or lines

The given parameters are:

Shape: regular octagon

A regular octagon has 8 sides, and the total sum of angles is 360

So, we have

Exterior angle = Total sum of angles/Number of sidee

This gives

Exterior angle = 360/8

Evaluate the quotient

Exterior angle = 45

Hence, the measure of the angle is 45 degrees

The expansion and simplified form of the expression [(x+3)(2x-1)(x+4)] will be (2x³ + x² - 25x - 12).

As per the question statement, we are provided with the expression of [(x+3)(2x-1)(x+4)] where three separate factors of the variable "x" are multiplied with each other.

We are required to expand and simplify the above-mentioned expression to obtain our desired answer.

Given, [(x + 3)(2x - 1)(x + 4)]

= [{(x + 3)*(2x - 1)}(x + 4)]

= [{(x*2x) - (x*1) + (3*2x) - (3*1)}(x + 4)]

= [(2x² - x - 6x -3)(x + 4)]

= [(2x² - 7x -3)(x + 4)]

= [(2x²*x) + (2x²*4) - (7x*x) - (7x*4) - (3*x) - (3*4)]

= [2x³ + 8x² - 7x² - 28x - 3x - 12]

The coordinates of Z are (-11.5, 5)

When a point on a line segment divides it into two segments, the formula used to determine the coordinates of that point is known as the section formula. Let us say, we have a point P(x,y) that divides the line segment with marked points as A (x1,y1) and B(x2,y2). To find the coordinates, we use the section formula, which is mathematically expressed as:

P(x, y) =  (m[tex]x_2[/tex] + n [tex]x_1[/tex] / m+ n, m [tex]y_2[/tex] +n[tex]y_1[/tex] /m+ n)

Given coordinates:

XY:XZ is 2:3

X is located at (6,10) and Y is located at (-1,8).

let the coordinates of Z(x, y)

using section formula

-1 = (2x + 18)/ 5

-5 = 2x +18

2x = -23

x= -11.5

and, 8 = 2y + 30 /5

40 = 2y + 30

2y= 10

y=5

Hence, the coordinates of Z are (-11.5, 5)

The integer solutions of the system of inequalities are x >= 1 and b <= 0

Inequality expressions are mathematical statements that are represented by variables, coefficients and operators where the opposite sides are not equal

System of inequalities 1

Here, we have

3 - 18x < 0

0.2 - 0.1x > 0

Rewrite as

0 < 0.2 - 0.1x

The above means that

3 - 18x  < 0.2 - 0.1x

Collect the like terms

So, we have

3 - 0.2 < 18x + 0.1x

Evaluate the like terms

So, we have

2.8 < 18.1x

Divide both sides by 18.1

So, we have

0.155 < x

Rewrite as

x > 0.155

The integer value greater than 0.155 is at least one

Hence, the integer solution of the system is x >= 1

System of inequalities 2

Here, we have

6 - 4b > 0

3b - 1 > 0

The above means that

6 - 4b > 0 < 3b - 1

Collect the like terms

So, we have

-4b > - 6 + 0 + 1< 3b

Evaluate the like terms

So, we have

-4b > -5 < 3b

Solve for b

b < -1.25 or -1.67 < b

The integer values in this case are 0

So, we have

b <= 0
