Divide the amount by the cost of capital, the length of time, and other factors to arrive at simple interest. Simple gain = initial + return + hours is the marketing formula. This system makes it easiest to calculating interest. The most conventional technique to figure out interest is as a portion of the principal sum. He will indeed pay his share of the 100percent annual interest, for example, if he borrows $100 from a partner and commits to pay it back with 5% concern. $100 (0.05) = $5. When you borrow money, you must pay interest, and when you give it out, you must charge interest. Interest is often determined as an extra component of the loan total. The interest on the loan is this percentage.

B = {5, 6, 9, 10}

Every element of A is also an element of B. Choose the correct answer below.

1. False

2. True

The answer to the equation is x = 6 or x = 6.

To solve the equation x^2 - 12x + 18 = 0 by completing the square, follow these steps:

Rewrite the equation in the form (x - a)^2 = b, where a and b are constants. In this case, a = 6 and b = 0.

Add (a^2 - b) to both sides of the equation to complete the square.

x^2 - 12x + 36 = 18

Factor the left side of the equation as a perfect square trinomial.

(x - 6)^2 = 0

Take the square root of both sides of the equation.

x - 6 = 0 or x - 6 = 0

Solve for x by adding or subtracting a to both sides of the equation.

Answer: A) The equation can be written as y = mx + b, where m is the slope and b is the y-intercept. The slope represents the cost per person and the y-intercept represents the fixed cost. Using the two given points, we can find the slope and y-intercept:

(15, 120) and (25, 200)

m = (200 - 120) / (25 - 15) = 80 / 10 = 8

b = 120 - 8 * 15 = 120 - 120 = 0

So the equation is y = 8x.

B) In the equation y = 8x, x represents the number of people attending the party and y represents the cost of having the party catered.

C) To predict the cost of having a party of 40 people catered, we plug in x = 40 into the equation:

y = 8x

y = 8 * 40

y = 320

So it will cost $320 to have a party of 40 people catered.

The proportion of the class with a midterm grade less than 75 is approximately 0.3085, or 30.85%. This means that 30.85% of the class is expected to have a midterm grade lower than 75.

We can use the cumulative distribution function (CDF) of the normal distribution to find the proportion of the class with a midterm grade less than 75.

The CDF of a normal distribution with mean μ and standard deviation σ evaluated at a point x is given by the formula:

CDF(x) = 0.5 * [1 + erf((x - μ) / (σ * √2))]

where erf is the error function.

For this problem, μ = 78 and σ = 6, and x = 75, so the CDF can be calculated as follows:

CDF(75) = 0.5 * [1 + erf((75 - 78) / (6 * √2))]

= 0.5 * [1 + erf(-0.3536)]

The value of erf(-0.3536) can be looked up in a table or calculated using a software package. The result is approximately -0.383.

CDF(75) = 0.5 * [1 + -0.383] = 0.5 * [0.617] = 0.3085

Completed the first step in dividing the fraction 45 ÷ 63 = 45/63 = 7/10.

What is fraction ?

A fraction is a part of a whole. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator. In a simple fraction, both are integers. A complex fraction has a fraction in the numerator or denominator. In a proper fraction, the numerator is less than the denominator.

Divide 45 by 63 to get the first digit of the quotient:

45 ÷ 63 = 7/10

Multiply 63 by 7/10 to get 45:

7/10 × 63 = 45

Subtract this result from 45:

45 - 45 = 0

Bring down the next digit (i.e., 43) to the next decimal place:

7/10

Constructing the four lines that intersect the circumference of the circle and form the square.

To construct a circle inscribed in a square, first draw a square with the desired side length.

Next, draw two diagonals from opposite corners of the square. This will divide the square into four quadrants. Measure the length of each diagonal.

Divide the length of each diagonal by two and mark the midpoints of each diagonal.

This will create four points which will define the circle. Connect each of the midpoints with a curved line to form a circle inscribed in the square.

Finally, use a compass to adjust the curve of the circle until it is perfectly symmetrical.

The circle should be perfectly centered in the square and tangent to each of its sides.

Answer: (A) Set compass to the diameter of the circle.

Step-by-step explanation:

The following formula can be used to get the coordinates of P such that P divides segment AB into parts having a part-to-whole ratio of 1 to 5 with A(-9, 3) and B(1, 8). P = (1 - t)A + TB.

where A and B are the coordinates of the segment's two endpoints, P's position on the segment AB is represented by the scalar value t, and

The part-to-whole ratio in this situation is 1:5, thus t equals 1/6.

In order to change the values of A, B, and t in the formula, we do as follows:

P = (1 - 1/6)A + (1/6)B

P = (5/6)A + (1/6)B

P = (-95/6, 35/6) + (1/6, 8/6)

P = (-15/2, 5/2) + (1/6, 4/3)

P = (-15/2 + 1/6, 5/2 + 4/3)

P = (-30/3, 23/6)

The positioning of P is (-10,3.83)

Regarding the second issue,

Using the same procedure as before, we can determine P's coordinates such that P divides segment AB in three equal halves if A(7, -4) and

B(-5, 4).

P = (1 - t)A + TB

The part-to-whole ratio in this situation is 3:1, therefore t equals 3/4.

In order to change the values of A, B, and t in the formula, we do as follows:

P = (1 - 3/4)A + (3/4)B

P = (1/4)A + (3/4)B

P = (7/4, -4/4) + (-53/4, 43/4)

P = (7/4 + -15/4, -4/4 + 3)

P = (-8/4, -1/4)

The positioning of P is (-2,-0.25)

Point P in the first issue is hence (-10,3.83), while Point P in the second issue is (-2,-0.25)

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

f(x)= -3x^2+4x+4

g(x)= x(-7x-7)

now,

f(x) + g(x)

=-3x^2+4x+4 +x(-7x-7)
