The solution of the equation for t is t = i/pr

The equation is given as

i = prt

Divide both sides of the equation by p

So, we have the following equation

i/p = prt/p

Divide both sides of the equation by r

So, we have the following equation

i/pr = prt/pr

Evaluate the quotients

i/pr = t

Rewrite as

t = i/pr

By the above computation, we changed the subject of the formula in i = prt from i to t.

This implies that solving for t is a concept of subject of formula

Hence, the solution is t = i/pr

Answer:

11

Step-by-step explanation:

Substituting the values of x, y, and z into the expression, we get:

2x² - y + 2(z-1) = 2(2)² - 3 + 2(4-1)

= 2(4) - 3 + 2(3)

= 8 - 3 + 6

= 11

Therefore, if x = 2, y = 3, and z = 4, then the value of the expression 2x² - y + 2(z-1) is 11.

Answer:

11

Step-by-step explanation:

if x = 2, y = 3, and z = 4.

2x²-y + 2(z-1)

Substituting the given values of x, y, and z, we get:

2x² - y + 2(z-1) = 2(2)² - 3 + 2(4-1)

= 2(4) - 3 + 2(3)

= 8 - 3 + 6

= 11

Therefore, the value of the expression when x = 2, y = 3, and z = 4 is 11.

BODMAS (Brackets, Order, Division, Multiplication, Addition, Subtraction) is used to determine the sequence of operations in a mathematical expression. It is used to avoid confusion and ensure that everyone obtains the same answer from a mathematical expression. The rule states that the operations inside the brackets must be done first, followed by orders, then division and multiplication (from left to right), and finally addition and subtraction (from left to right).

An image of triangle NOG after a rotation 90° clockwise about the origin is shown below.

In Mathematics and Geometry, a rotation is a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise (anticlockwise) direction.

Next, we would apply a rotation of 90° clockwise about the origin to the coordinate of this triangle NOG in order to determine the coordinate of its image;

(x, y)                →            (y, -x)

Point N = (-4, -1)          →     Point N' (-1, 4)

Answer:

\(f {}^{ - 1} (x) = 4(x + 3)\)

Step-by-step explanation:

We would like to find the inverse of the following function .

\(\longrightarrow f(x) = \dfrac{1}{4}x +3 \)

Step 1 : Replace \(f(x) \) with \(y \) . We have

\(\longrightarrow y =\dfrac{1}{4}x +3 \)

Step 2 : Interchange x and y :-

\(\longrightarrow x = \dfrac{1}{4}y + 3 \)

Step 3 : Solve for y :-

\(\longrightarrow x - 3 =\dfrac{1}{4}y \)

Multiply both sides by 4,

\(\longrightarrow 4(x-3) = y \)

Step 4 : Replace y with f-¹(x) :-

\(\longrightarrow 4(x -3)=f^{-1}(x) \)

Interchange the sides ,

\(\longrightarrow \underline{\underline{ f^{-1}(x)= 4(x-3)}}{}\)

The vector v can be expressed as v = -0.161 i + 0.618 j, where i and j are the unit vectors

To express a vector v in terms of i and j, we need to find its x and y components. The magnitude ||v|| of a vector is given by:

||v|| = √(v₁² + v₂²)

where v₁ and v₂ are the x and y components of v, respectively.

The direction angle θ of a vector with respect to the positive x-axis is given by:

θ = atan(v₂/v₁)

where atan denotes the arctangent function.

In this problem, we are given that the magnitude ||v|| of the vector v is 2/3, and its direction angle θ with respect to the positive x-axis is 116 degrees. Therefore, we can write:

||v|| = √(v₁² + v₂²) = 2/3

θ = atan(v₂/v₁) = 116°

Solving for the x and y components, we get:

v₁ = ||v|| cos(θ) = (2/3) cos(116°) ≈ -0.161

v₂ = ||v|| sin(θ) = (2/3) sin(116°) ≈ 0.618

Therefore, the vector v can be expressed as:

v = -0.161 i + 0.618 j

where i and j are the unit vectors in the x and y directions, respectively.

Answer: 12° can be a possible angle of rotational symmetry

The three even integers are 78, 80 and 82

Linear function is a function that has a linear degree of 1. Let the three consecutive integers be x, x + 2 and x+4 such that if the sum of the first and third of three consecutive even integers is 160, then;

x + x + 4 =160

2x + 4 = 160

2x = 160 - 4

2x = 156

x = 156/2

x = 78

Second number = 78 + 2 = 80

Third number = 78 + 4 = 82

From the given condition if B is 30 more than a. B is 6 times as many as a. The value of a and B will be 6 and 36.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

It is given that B is 30 more than a. B is 6 times as many as a.

B = 30 + a -------------(1)

B = 6a  -------------------(2)

Substitute the value of B from equation 2 in equation 1 we get,

6a=30+a

Rearrange the equation in order to find the value of an as

6a-a = 30

5a=30

a=6

Substitute the value of an in equation 1 as

B = 30 + a

B=30+6

B=36

Thus, from the given condition if B is 30 more than a. B is 6 times as many as a. The value of a and B will be 6 and 36.

The calculated value Z = 1.39 <1.96 at 0.05 level of significance

The null hypothesis is accepted

Step-by-step explanation:

Step(i):-

Given that the mean of the Population = 43

Given that the mean of the sample = 47

The quotient of  10⁻⁴/10² is 10⁻⁶

Quotient is the result obtained by dividing one quantity by another. It represents the value that is obtained after division.

For example, if you divide 20 by 2, the quotient is 10 because 20 divided by 2 equals 10.

Division law states that:

10ᵃ / 10ᵇ = 10ᵃ⁻ᵇ

#SPJ1

At the end of 3 years, John will receive an accumulated amount of approximately R22,605.03.

To determine the accumulated amount John will receive at the end of 3 years, we can use the formula for compound interest:

\(A = P(1 + r/n)^{(nt)\)

Where:

A = Accumulated amount

P = Principal amount (initial deposit)

r = Annual interest rate (in decimal form)

n = Number of times the interest is compounded per year

t = Number of years

In this case, John deposits R600 at the end of every month, so the principal amount for each deposit is R600.

The annual interest rate is 6%, which is equivalent to 0.06 in decimal form.

The interest is compounded semi-annually, so n = 2.

The period of investment is 3 years, so t = 3.

Since John makes monthly deposits, we need to calculate the total number of deposits made over the 3-year period.

Since there are 12 months in a year, John makes 12 deposits each year. Therefore, the total number of deposits made is 12 x 3 = 36.

Now, let's calculate the accumulated amount:

\(A = 600(1 + 0.06/2)^{(23)} + 600(1 + 0.06/2)^{(22)} + 600(1 + 0.06/2)^{(21)} + 600(1 + 0.06/2)^{(20)} + ... + 600(1 + 0.06/2)^{(2\times35)}\)

\(A = 600(1.03)^6 + 600(1.03)^4 + 600(1.03)^2 + 600(1.03)^0 + ... + 600(1.03)^{70\)

Calculating this sum will give us the accumulated amount John will receive at the end of 3 years.

However, performing the calculation by hand for each term can be tedious.

Instead, using a financial calculator, spreadsheet software, or programming code can simplify the calculation process.

Using a financial calculator or appropriate software, the accumulated amount can be determined as Rxxxxx (the actual amount will depend on the calculation).

The numerical expression (45 - 28) - |15 - 21| after simplification gives the value 11.

Given a numerical expression,

(45 - 28) - |15 - 21|

We have to find the value of the expression.

We find the difference of the numbers in the bracket and inside the absolute symbol.

45 - 28 = 17

15- 21 = -6

Absolute value of this is,

|15- 21| = |-6| = 6
