Answer:

VAT = R239.85

Step-by-step explanation:

VAT = 15%

15/100 = 0.15

R1599 × 0.15 = 239.85

VAT = R239.85

Answer:

Step-by-step explanation:

\(\\ \sf\longmapsto V=\pi r^2h\)

\(\\ \sf\longmapsto 11.25=5\pi r^2\)

\(\\ \sf\longmapsto 2.25=\pi r^2\)

\(\\ \sf\longmapsto r^2=2.25/3.14=0.71\)

\(\\ \sf\longmapsto r=\sqrt{0.71}\)

\(\\ \sf\longmapsto r=0.84in\)

Answer:

Diameter is 3.00 inches

Step-by-step explanation:

» Volume of a cylindrical soup is given a formula below:

\({ \tt{volume = \pi {r}^{2} h}}\)

\({ \tt{11.25\pi = \pi( {r}^{2} ) \times 5}}\)

» Divide either sides by 5π

\({ \tt{ \frac{11.25\pi}{ \green{5\pi}} = \frac{\pi {r}^{2} \times 5}{ \green{5\pi}} }} \\ \\ { \tt{2.25 = {r}^{2} }} \\ { \tt{ \sqrt{ {r}^{2} } = \sqrt{2.25} }} \\ { \tt{r = 1.5 \: in}}\)

» From identical circular formulae, diameter is twice radius:

\( { \boxed{ \tt{ \: diameter = 2 \times radius \: }}} \\ { \tt{d = 2 \times 1.5}} \\ { \tt{d = 3 \: inches}}\)

Step-by-step explanation:

Yes, because there is a constant rate of change. It is and will always be constantly increasing by 1.5.

To be a linear line you have to have a constant rate of change.

Answer:

C

Step-by-step explanation:

cot²θ = 1/tan²θ

plug this in to get

1/(1/tan²θ + 1)

1/tan²θ + 1 = 1/tan²θ + tan²θ/tan²θ = (1+tan²θ)/tan²θ

we then have

1/((1+tan²θ)/tan²θ)

1/(x/y) = y/x, so this is equal to

tan²θ/(1+tan²θ)

tan²θ = sin²θ/cos²θ, so plug this in to get

(sin²θ/cos²θ)/(1+sin²θ/cos²θ)

1+sin²θ/cos²θ = cos²θ/cos²θ + sin²θ/cos²θ

sin²θ + cos²θ = 1, so we have

(cos²θ+sin²θ)/cos²θ = 1/cos²θ. plug this in to get

(sin²θ/cos²θ)/(1/cos²θ)

(a/b)/(c/d) = (d/c) * (a/b), so we have

(sin²θ/cos²θ)/(1/cos²θ)  = cos²θ/1 * sin²θ/cos²θ = sin²θ

The number of gallons of  8% butterfat is 139 and the number of gallons of 3% butterfat milk is 146.

An equation is a statement that two mathematical expressions have values that are equal. Simply said, an equation proves that two things are equal. It is denoted by the equals sign, or "=."

Given:

A dairy needs 285 gallons of milk containing 6% butterfat,

The other milk is 8% butterfat and milk containing 3% butterfat,

Assume, the number of gallons of 8% butterfat milk is M then,

The number of gallons of 3% butterfat milk is = 285 - M,

Write the equation as shown below,

M × 8% + (285 - M) × 3% = 6% × 258

Solve for the value of M as shown below,

0.08 M + 8.55 - 0.03 M = 15.48

0.05 M = 6.93

M = 138.6 or 139

The number of gallons of 3% butterfat milk is = 285 - 139 = 146

What is a linear equation?

At first it is important to know about linear equation

Equation shows the equality between two algebraic expressions by connecting the two algebraic expressions by an equal to sign.

A one degree equation is known as linear equation.

Length of two sides of a right angled triangle = x, x+2

Area = \(\frac{1}{2}\times x \times (x + 2)\)

By the problem,

The linear equation is

After answering the provided question, we can conclude that As a result, with continuous compounding at a fixed annual interest rate of 2.67%, Jacob's investment will reach $25,000 in approximately 30.6 years.

In mathematics, interest refers to the amount of revenue raised or owed on an original cost or loan. You can use either simple or compound interest. Simple interest is determined by a proportion of the original amount, whereas compound interest is calculated on the principal amount and as well as any previously earned interest. If you put money $100 at a 5% yearly simple interest rate, visitors will earn $5 in interest every year for three years, for a total of $15.

To solve this problem, we can use the continuous compounding formula:

\(A = Pe^(rt)\\25000 = 8634e^(0.0267t)\\e^{(0.0267t)}= 2.893\\0.0267t = ln(2.893)\\t = ln(2.893) / 0.0267 ≈ 30.6 years\\\)

As a result, with continuous compounding at a fixed annual interest rate of 2.67%, Jacob's investment will reach $25,000 in approximately 30.6 years.

P=160-70*cos(2π*(1/12)*t)

• Pressure in mathematics or physics is defined as force per unit area. The pressure exerted by a solid object which is resting on top of a solid surface is the weight divided by the area of the object . SI unit of force is Newton (N).

First, we find the amplitude by taking the difference between the peak values and dividing by two:

Amplitude=(230+90)/2=70

We can find the center value by either adding 70 to the minimum or subtracting 70 from the maximum:

90+70=160

230-70=160

This tells us that the Center Value=160

The frequency that we are operating at is given as:

f = 5/hour

so in minutes

f=5*(1/60)/minute=5/60=1/12 per minute

According to the question an example of C = 3 and D = 2 supports the answer that Equation A gives a bigger value than Equation B.

Two equations are considered to be comparable when their roots and solutions line up. To create an equivalent equation, the identical quantity, symbol, or expression has to be added to or removed from both of the equation's two sides. We can also create a similar equation by dividing or multiplying each component of an equation with a nonzero value.

given,

To determine which equation would give a bigger value, we can compare the expressions obtained by expanding Equation A and simplifying Equation B.

Expanding Equation A, we get:

A = (C + D) x (C + D) = C² + 2CD + D²

Simplifying Equation B, we get:

B = 2 x (C + D) = 2C + 2D

To compare the values of A and B, let's choose some values for C and D that are greater than zero. Let's choose C = 3 and D = 2.

Plugging these values into Equation A, we get:

A = 3² + 2(3)(2) + 2² = 9 + 12 + 4 = 25

Plugging these values into Equation B, we get:

B = 2(3 + 2) = 2(5) = 10

Since A is greater than B for the values of C = 3 and D = 2, we can conclude that Equation A gives a bigger value than Equation B for positive values of C and D.

Therefore, an example of C = 3 and D = 2 supports the answer that Equation A gives a bigger value than Equation B.

If the value of a certain collectible card in dollars from January 2020 to May 2021 can be modeled by the function V(m)=250m² – 3,500m + 18,000, the value of the card was declining over the period 0 < m < 7.

To determine when the value of the collectible card was declining, we need to look for when the first derivative of the function is negative. If the first derivative of the function is negative over a certain period, then the function is decreasing over that period. The first derivative of the function V(m) is:

V'(m) = 500m - 3,500

To find when the value of the card was declining, we need to solve the inequality V'(m) < 0. Solving for m, we get:

500m - 3,500 < 0

500m < 3,500

m < 7

Therefore, the value of the card was declining over the period 0 < m < 7. This corresponds to the months from January 2020 to July 2020. During this period, the first derivative of the function V(m) is negative, which means the value of the card was decreasing.

Answer:

Hence, the equation of a sphere with one of its diameters with endpoints (-9, -12, -6) and (11, 8, 14) is \((x-1)^{2}+(y+2)^{2}+(z-4)^{2} = 30\).

Step-by-step explanation:

There are two kew parameters for a sphere: Center (\(h\), \(k\), \(s\)) and Radius (\(r\)). The radius is the midpoint of the line segment between endpoints. That is:

\(C(x,y,z) = \left(\frac{-9+11}{2},\frac{-12+8}{2},\frac{-6+14}{2} \right)\)

\(C(x,y,z) = (1,-2,4)\)

The radius can be found by halving the length of diameter, which can be determined by knowning location of endpoints and using Pythagorean Theorem:

\(r = \frac{1}{2}\cdot \sqrt{(-9-11)^{2}+(-12-8)^{2}+(-6-14)^{2}}\)

\(r = 10\sqrt{3}\)

The general formula of a sphere centered at (h, k, s) and with a radius r is:

\((x-h)^{2}+(y-k)^{2}+(z-s)^{2} = r^{2}\)

Hence, the equation of a sphere with one of its diameters with endpoints (-9, -12, -6) and (11, 8, 14) is \((x-1)^{2}+(y+2)^{2}+(z-4)^{2} = 30\).

The inverse of f(x) = x^(7/9) using exponential notation is f(x) = x^(9/7)

An inverse function in mathematics is a function that "undoes" another function.

In other words, if f(x) yields y, then y entered into the inverse of f yields the output x.

An invertible function is one that has an inverse, and the inverse is represented by the symbol f⁻¹.

The given function is of the form

f(x) = x^(7/9), this is equivalent to ⁹√x⁷

say f(x) = y, then

f(x) = y = x^(7/9)

y = x^(7/9)

solving for the inverse, of y = x^(7/9)

y = x^(7/9)

y^(9/7) = x

interchanging the letters

y = x^(9/7)

hence the inverse function is solved to be f⁻¹(x) = x^(9/7)

Step-by-step explanation:

Total revenue from 1st movie

16×100 = 1600

Revenue from 2nd and 3rd movie = 4980 - 1600 = 3380

Total number of tickets sold = 310

Number of tickets sold for 2nd and 3rd movie combined = 310 - 100 = 210

Let x be number of 2nd movie tickets, y be number of 3rd movie tickets

x + y = 210, multiplying this by 13,

13x + 13y = 2730   (1)

13x + 18y = 3380   (2)
