that the demand for the product is said to be inelastic.

when the demand for a product is inelastic, it means that consumers are not very sensitive to changes in the price of the product. This could be because there are no close substitutes for the product, or because the product is a necessity that consumers cannot easily do without.

when market demand hardly changes with a small change in the price of a product, it indicates that the demand for the product is inelastic.


When the market demand for a product does not change significantly with a small change in the price, this indicates that the product's demand is inelastic. Inelastic demand means that the percentage change in quantity demanded is less than the percentage change in price. Consumers are less sensitive to price changes for inelastic goods, often because they are necessities or have few substitutes.

The demand for a product that hardly changes with small price fluctuations is best described as inelastic.

Answer:

Solving the given formula for v2 gives us:

\(a(t_2-t_1)+v_1 = v_2\)

Step-by-step explanation:

Solving an equation for a particular variable means that the variable has to be isolated on one side of the equation.

Given equation is:

\(a = \frac{v_2-v_1}{t_2-t_1}\)

Multiplying both sides by t2-t1

\((t_2-t_1) . a = \frac{v_2-v_1}{t_2-t_1} . (t_2-t_1)\\a(t_2-t_1) = v_2-v_1\)

Adding v1 to both sides of the equation

\(a(t_2-t_1)+v_1 = v_2-v_1+v_1\\a(t_2-t_1)+v_1 = v_2\)

Hence,

Solving the given formula for v2 gives us:

\(a(t_2-t_1)+v_1 = v_2\)

Henry opens a savings account with an annual interest rate of 4.5 percent. After a year, he gets $75,000 in payment. He made a deposit into the savings account of $72,831.68.

Here are the steps on how to calculate the amount Henry invested:

Convert the annual interest rate to a monthly rate.

\(\begin{equation}4.5\% \div 12 = 0.375\%\end{equation}\)

Calculate the number of years.

\(\begin{equation}\frac{18 \text{ months}}{12 \text{ months/year}} = 1.5 \text{ years}\end{equation}\)

Use the compound interest formula to calculate the amount Henry invested.

\(\begin{equation}FV = PV * (1 + r)^t\end{equation}\)

where:

FV is the future value ($75,000)

PV is the present value (unknown)

r is the interest rate (0.375%)

t is the number of years (1.5 years)

\(\begin{equation}\$75,000 = PV \cdot (1 + 0.00375)^{1.5}\end{equation}\)

\$75,000 = PV * 1.0297

\(\begin{equation}PV = \frac{\$75,000}{1.0297}\end{equation}\)

PV = \$72,831.68

Therefore, Henry invested \$72,831.68 in the savings account.

This indicates that the Australian dollar appreciated by 5.80%. the correct answer is (a) appreciated; 5.80.

To determine whether the Australian dollar appreciated or depreciated and by what percentage, we can calculate the percentage change in value between today and yesterday.

The formula for calculating the percentage change is:

Percentage Change = (New Value - Old Value) / Old Value * 100

Using this formula, we can calculate the percentage change:

Percentage Change = (0.73 - 0.69) / 0.69 * 100

Percentage Change = 0.04 / 0.69 * 100

Percentage Change ≈ 5.80

The percentage change is approximately 5.80%. This indicates that the Australian dollar appreciated by 5.80%.

The answer is parallel.The slope of the two lines is the same, i.e., -3. Hence, both lines are parallel to each other. Therefore, the answer is parallel.

First of all, we have to find the equation of each line, given the point-slope form:

Slope of the line passing through (-2, 2) with a slope of -3:

Since the slope of the line is -3 and it passes through (-2, 2), the equation is:

y - 2 = -3(x + 2) ⇒ y - 2 = -3x - 6 ⇒ y = -3x - 4

The equation of the first line is y = -3x - 4.

Slope of the line passing through (2, -2) with a slope of -3:

Since the slope of the line is -3 and it passes through (2, -2), the equation is:

y - (-2) = -3(x - 2) ⇒ y + 2 = -3x + 6 ⇒ y = -3x + 4

The equation of the second line is y = -3x + 4.

A NORMAL distribution is a symmetrical probability distribution with a bell-shaped curve. It is also called a Gaussian distribution or a normal curve. This distribution is often used in statistics to represent a large number of natural phenomena, such as the distribution of height, weight, or IQ scores in a population.

The first deviation of a NORMAL distribution includes 68.2% of the data. This means that if we were to take a random sample of data from a normally distributed population, about 68.2% of the data would be within one standard deviation of the mean.

The second deviation includes 95.4% of the data. This means that about 95.4% of the data would be within two standard deviations of the mean.

The third deviation includes 99.7% of the data. This means that about 99.7% of the data would be within three standard deviations of the mean.

It is important to note that while these percentages hold true for a NORMAL distribution, they may not apply to other types of distributions.

To find f(x) and g(x) for the given function y = 9/sqrt(5x+5), we need to express y in the form y = f(g(x)).
Let's start by defining g(x) as the expression inside the square root, i.e., g(x) = 5x+5.
Next, we need to find f(x) such that f(g(x)) = y. To do this, we can simplify the given expression for y:
y = 9/sqrt(5x+5)
y * sqrt(5x+5) = 9

Squaring both sides:
(y * sqrt(5x+5))^2 = 9^2
5xy + 45y^2 + 45y - 81 = 0
Now we can solve for y in terms of g(x) (i.e., y = f(g(x))) using the quadratic formula:
y = (-45 ± sqrt(2025 - 4*5*g(x)*(-81))) / (2*5)
y = (-45 ± sqrt(2025 + 1620g(x))) / 10

So our final answer is:
f(x) = (-45 ± sqrt(2025 + 1620x)) / 10
g(x) = 5x+5
(Note: there are two possible values of f(x) because of the ± sign in the quadratic formula, but either one will work to give the original function y = 9/sqrt(5x+5) as y = f(g(x)).)

Answer:

Step-by-step explanation:

Determine the amount of sales she made that month

a. The total amount of sales is Ksh 450,000

b. Her commission in february is  Ksh 34,480

Total earning is Ksh 43,860

a) Jane's total earnings in January were Ksh 48,000, and her base salary is Ksh 20,000. This means that she earned an additional Ksh 28,000 in commissions.

Since her commission rate is 8% for sales in excess of Ksh 100,000, we can calculate the amount of sales she made in January by first calculating the sales over which she got a commission.

Ksh 28,000 is 8% of the sales over Ksh 100,000. So we can set up the following equation and solve for the sales:

0.08 * sales = 28,000

Solving for sales:

sales = 28,000 / 0.08 = Ksh 350,000

Since she only earns a commission on sales in excess of Ksh 100,000, the total amount of sales she made in January would be:

Ksh 100,000 (no commission threshold) + Ksh 350,000 (sales over the threshold) = Ksh 450,000

b) i) If her total sales in February increased by 18%, her sales in February were:

1.18 * Ksh 450,000 = Ksh 531,000

But remember, she only gets a commission on sales over Ksh 100,000. So the sales that will earn a commission in February are:

Ksh 531,000 - Ksh 100,000 = Ksh 431,000

Her commission in February is 8% of this amount:

0.08 * Ksh 431,000 = Ksh 34,480

ii) If her sales in March then dropped by 25%, her sales in March were:

0.75 * Ksh 531,000 = Ksh 398,250

The sales that will earn a commission in March are:

Ksh 398,250 - Ksh 100,000 = Ksh 298,250

Her commission in March is 8% of this amount:

0.08 * Ksh 298,250 = Ksh 23,860

So, her total earnings in March (her base salary plus her commission) would be:

Ksh 20,000 + Ksh 23,860 = Ksh 43,860
