which value of a make the solution of the equation 3(2x-4) = 4(ax-2)

Based on the given parameters, the amount of the investment after 2 years is $3123

The given parameters about the compound interest are

Principal Amount, P = $3000

Interest Rate, R = 2%

Time, t = 2

Number of times, n = 4 i.e quarterly

Compound interests are different from simple interest, and they are calculated using the following compound interest formula

CI = P(1 + R/n)^nt - P

To calculate the amount, we have:

A = P + CI

So, the equation becomes

A = P + P(1 + R/n)^nt - P

Evaluate the like terms

A = P(1 + R/n)^nt

Substitute the known values in the above equation

A = 3000 * (1 + 2%/4)^(2 * 4)

Express 2% as decimal

A = 3000 * (1 + 0.02/4)^(2 * 4)

Evaluate the sum

A = 3000 * (1.005)^8

Evaluate the exponent

A = 3000 * 1.041

Evaluate the product

A = 3123

Hence, the value of the investment is $3123

The slope of the line that passes through points (10,4) and (7, 3) is 1/3

Here we are dealing with a slope of a line where a slope of a line is the change in the y coordinate with regard to the change in the x coordinate. If P(x1,y1) and Q(x2,y2) are the two points on a straight line, at that point the slope formula is given by:

m = Change in y-coordinates/Change in x-coordinates

m = (y₂– y₁)/(x₂ – x₁)

Since we are given two points (10,4) and (7, 3),  where x₁ and x₂ are 10, 7 whereas y₁ and y₂ are 4, 3

From  the formula we get,

m = (y₂-y₁)/(x₂-x₁)

The missing integer that makes the following addition statement true is -1.

The commutative law of addition is also known as the law of cumulative addition and it states that when two numbers are added together, then, the outcome is equal to the addition of their interchanged position because addition is considered as a binary operation.

Mathematically, the commutative law of addition can be represented using the following formula:

A + B = B + A.

An integer can be defined as a whole number that may either be positive, negative, or zero such as -1, 0, 1, 2, 3, etc.

Applying the rules for the polar equations, the correct pairs are given in the image at the end of the answer.

The most well known polar equation rules are given as follows:

For the first pair, when x = 2, we have that:

rcos(θ) = 2.

r = 2/cos(θ)

r = 2 sec(θ), as one divided by the cosine is the secant.

For the second pair, we have that:

x² + y² = 36.

x² + y² = r², hence:

r² = 36

r = 6.

For the third pair, we have that:

x² + y² = 2y

r² = 2rsin(θ).

r²/r = 2sin(θ).

r = 2sin(θ).

For the fourth pair, we have that:

[tex]x = \sqrt{3}y[/tex]

[tex]\frac{y}{x} = \frac{1}{\sqrt{3}}[/tex]

[tex]\frac{y}{x} = \frac{\sqrt{3}}{3}[/tex]

Then the angle theta is given as follows:

θ = arctan(sqrt(3)/3) = pi/6.

For the fifth pair, we have an angle in which the sine and the cosine are equal, hence this angle is of 45º = pi/4.

The image at the end of the answer shows all the matched pairs.

The area of mathematics known as algebra aids in the representation of issues or circumstances into mathematical statements. To create a meaningful mathematical expression, it requires variables like x, y, and z as well as mathematical operations like addition, subtraction, multiplication, and division. Algebra is used in all areas of mathematics, including coordinate geometry, calculus, and trigonometry. 2x + 4 = 8 is a basic algebraic expression.When operations like addition, subtraction, multiplication, division, etc. are performed on variables and constants, we obtain algebraic expressions as the mathematical statement.

After evaluating the limit we have came to find that the limit of  [tex]\lim_{x\rightarrow -\infty }\frac{x^2}{x^2\ +4}[/tex] as x approaches ∞- is 1

The value that a function, sequence, or index approaches as an input, or an index, approaches a particular value is known as a limit in mathematics. Limits, which are essential to calculus and mathematical analysis, are required by the definitions of continuity, derivatives, and integrals.

In addition to being closely related to the concepts of limit and direct limit in category theory, the idea of a limit of a sequence is further generalised to encompass the idea of a limit of a topological network.

A limit of a function is typically expressed in formulas as

[tex]{\displaystyle \lim _{x\to c}f(x)=L,}[/tex]

To find the limit we will use L'Hôpital's Rule

By the rules of probability

P(A or  B) = P(A) + P(B) - P( A and  B)  
So P(A or b ) = 0.45 + 0.65 - 0.35 = 0.75

The complement of a set A is all the elements not in A
P(A') = 1 - P(A)

If we denote the complement of a set A as A' then your second expression is asking What is the complement of A or B or P(A or B)'
P(A and  B)' = 1 - P(A or B) = 1- 0.75 = 0.25

P(A|B)  = P(A and  B)/P(B) = 0.35/0.65 = 0.54

P(B|A) = P(A and B)/P(A) = 0.35/0.45 = 0.78

1.4 Relations and Functions

A relation is a correspondence between two sets. If x and y are two

elements in these sets and if a relation exists between x and y, then x

corresponds to y, or y depends on x.

DEFINITION OF A FUNCTION:

Let X and Y two nonempty sets. A function from X into Y is a relation that

associates with each element of X, exactly one element of Y.

However, an element of Y may have more than one elements of X

associated with it.

That is for each ordered pair (x,y), there is exactly one y value for each x,

but there may be multiple x values for each y. The variable x is called the

independent variable (also sometimes called the argument of the

function), and the variable y is called dependent variable (also

sometimes called the image of the function.) x = y2 is not a function from X into Y, because there

is not exactly one y value for each x.

Solving for y, you get y =

which means there are two possible values for y

Step-by-step explanation:

4y + 5 = 2  Subtract 5 from both sides

4y = -3  Divide both sides by 4

y = [tex]\frac{-3}{4}[/tex]

Answer:

4y+5=2

Step-by-step explanation:

First, replace "a number" with "y"
The sentence becomes: "The sum of 4 times y and 5 is 2"
Replace "is" with the equals sign, "="
The sentence becomes: "The sum of 4 times y and 5 = 2"
Replace "times" with the multiply symbol, " * "
The sentence becomes: "The sum of 4 * y and 5 = 2"
Replace "the sum of ___ and ___" with " ___ + ___"

The sentence becomes: "4*y + 5 = 2".
the " * " isn't needed since 4y implies multiplication already, so you can optionally remove the *

To be able to get the expected value of Z, we will be using the following formula:

We get,

Therefore, the expected value of Z is -12.29.

After substituting x = -1/2 in f(x), the value of the function f(-1/2) is found to be 5.333.

A function from a set X to a set Y assigns exactly one element of Y to each element of X.

The set X is known as the function's domain, and the set Y is known as the function's codomain.

The given function is f(x) = -2/3x +5.

To obtain f(-1/2), we must substitute the value of x with -(1/2).

f(x) = -2/3x +5

f(-1/2) = -2/3×(-1/2) + 5

f(-1/2) = (2/6) + 5

f(-1/2) = 0.333 + 5

∴ f(-1/2) = 5.3333

Therefore, the value of the function f(-1/2) obtained after substituting        x = -1/2 is 5.333.

The approximate probability that a randomly selected 10-year-old child will be more than 51.75 inches tall is 0.6915.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. From the information, the heights of 10-year-old children have a normal probability distribution with a mean of 54.6 inches and standard deviation of 5.7 inches.

Based on this, the probability that a randomly selected 10-year old child will be more than 51.75 inches tall will be:

P(X > 51.75)

= P(Z > [(number - mean) / standard deviation)]

= P(Z > [(51.75 - 54.6) / 5.7)]

= P(Z > -0.5)

= 1 - P(Z = -0.5)

This will be looked at in the z table.

The value of x that makes m and n parallel is 15.

How to find the angles in parallel lines?

When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate angles, vertically opposite angles etc.

The value of x that makes the line ma and n parallel can be calculated as follows:

180 - x  = x (alternate exterior angle)

180  = 2x

x = 180 / 2

x = 90 degrees
