The shortest distance the joggers must travel to return to their starting point is 7.81 miles.

To find the shortest distance the joggers must travel to return to their starting point, we can use the Pythagorean theorem, as the southward and eastward distances form a right triangle. The theorem states that the square of the length of the hypotenuse (the shortest distance, in this case) is equal to the sum of the squares of the other two sides:

a^2 + b^2 = c^2

Here, a is the southward distance (6 miles), and b is the eastward distance (5 miles). We need to find c, the hypotenuse.

(6 miles)^2 + (5 miles)^2 = c^2

36 + 25 = c^2

61 = c^2

Now, take the square root of both sides to find c:

c = √61

c ≈ 7.81 miles

Answer:

A) Total amount to be paid = Birr 8,560

B) Amount of VAT liable to the dealer = Birr 520

Step-by-step explanation:

The tax on bought commodity and the tax on sold commodity isn't provided but in some places, these values are 7% and 9% respectively. So, these are the values that will be used for this question.

Note that these values vary from country to country and the value missing from this question will not change how the question is solved; the question will still be solved in a similar manner, only the parameters will vary.

A) The dealer bought Birr 8000 at 7% tax.

Total amount to be paid = cost price (1 + r%)

r = 7% = 0.07

Total amount to be paid = 8000 × 1.07 = Birr 8,560

B) To find the VAT, it is the difference between the tax paid when the good was bought and the tax put on it after it was sold.

Tax paid when the shoes were bought = 7% of cost price = 7% × 8,000 = Birr 560

Tax paid when the shoes were sold = 9% of selling price = 9% × 12,000 = Birr 1,080

VAT = tax recovered on sale - Tax paid on purchase

VAT = 1080 - 560 = Birr 520

Answer:

\(11\dfrac{3}{5}$ miles\)

Step-by-step explanation:

Miguel ran \(2\dfrac{9}{10}\) miles on Monday.

On Friday, he ran 5 times as far as he did on Monday.

Miles run on Friday

\(=5 X 2\dfrac{9}{10}\)

\(=5 X \dfrac{29}{10}\\=\dfrac{29}{2}$ miles\)

Difference in Number of Miles Run

\(=\dfrac{29}{2}-\dfrac{29}{10}\\=\dfrac{145-29}{10}\\=\dfrac{116}{10}\\=11\dfrac{3}{5}$ miles\)

Therefore, Miguel ran \(11\dfrac{3}{5}$ miles\) farther on Friday.

Option A: 18.169 and 27.690.

The confidence interval for the true slope of the population regression line is (0.2, 0.4), indicating that we are 95% confident that the true slope falls within this interval.

What is Statistics?

Statistics is the branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of data

In regression analysis, a regression line is a straight line that describes how a response variable y changes as an explanatory variable x changes. The slope of the regression line represents the change in the response variable y per unit change in the explanatory variable x.

Sure, here is a numerical example:

Suppose we want to estimate the relationship between height and weight among adults, and we collect a sample of 100 adults and measure their height and weight. We can use linear regression to model the relationship between these variables, and estimate the slope and intercept of the population regression line.

Suppose the slope of the true population regression line is unknown, but we calculate a 95% confidence interval for it based on the sample data, and obtain the interval (0.2, 0.4). This means that we are 95% confident that the true slope of the population regression line falls between 0.2 and 0.4.

If we were to repeat the sampling process many times and construct confidence intervals in the same way, we would expect that about 95% of those intervals would contain the true value of the population slope. However, we cannot be completely certain that the true value falls within this interval, as there is always some degree of uncertainty in statistical inference.

In the given question, the statement "we are 95% confident that the true population regression line (i.e. slope) will fall between" implies that a confidence interval is being constructed for the true slope of the regression line. The four options represent different intervals for the true slope, and only one of them can be correct.

Step-by-step explanation:

4.1 The tariff for electricity consumption is R2.55 per kilowatt-hour (kWh).

4.2 The cost of electricity for 80 kWh is R204

4.3 One way of saving electricity is by ensuring energy-efficient practices such as putting off lights, electronics, and appliances when not in use and using LED or other energy-efficient light bulbs.

4.4.1 The oven uses 1.5 kilowatts of electricity per hour.

4.4.2 The amount of money left on the meter after baking for 4 hours is  R39.70.

4.2 To calculate the cost of electricity for 80 kWh, we shall use the formula:

Cost = R2,55 x number of kWh of electricity used:

Cost = R2,55 x 80

= R204

Therefore, the cost of electricity for 80 kWh is R204.

4.4.1 We calculate the kilowatts (kW) of electricity the oven uses per hour, by converting the watts to kilowatts.

1 kilowatt (kW) = 1000 watts

Oven uses 1500 watts each hour, so we convert:

1500 watts = 1500/1000 = 1.5 kilowatts (kW)

So, the oven uses 1.5 kilowatts of electricity per hour.

4.4.2 If Mary has R55,00 worth of electricity and bakes for 4 hours, we compute the cost of electricity used during baking.

Cost of electricity used for baking = Cost per kWh x number of kWh used

= R2,55 x (1.5 kW x 4 hours)

= R2,55 x 6 kWh

= R15.30

Next, we estimate the amount of money left on the meter after baking:

Amount left on meter = Initial amount - Cost of electricity used

= R55.00 - R15.30

= R39.70

Hence, Mary will have R39.70 left on the meter after baking for 4 hours.

Answer: 0.33 = 33/10 0.4 = 4/10 So, 33/10 is greater than 4/10. That means 0.33 is greater than 0.4.

Part 1: Operations of Functions

1. Given f(x) = x² + 7x + 12 and g(x) = x² - 9, we can perform the operations as follows:

(a) (f + g)(x):

(f + g)(x) = f(x) + g(x)

          = (x² + 7x + 12) + (x² - 9)

          = 2x² + 7x + 3

(b) (f - g)(x):

(f - g)(x) = f(x) - g(x)

          = (x² + 7x + 12) - (x² - 9)

          = 16x + 21

(c) (-9)(x):

(-9)(x) = -9x

(d) ((x):

((x) is not specified. Please provide the correct function to perform the operation.

2. Given f(x) = 2x + 1 and g(x) = x - 3, we can perform the operations as follows:

(a) (f + g)(x):

(f + g)(x) = f(x) + g(x)

          = (2x + 1) + (x - 3)

          = 3x - 2

(b) (f - g)(x):

(f - g)(x) = f(x) - g(x)

          = (2x + 1) - (x - 3)

          = x + 4

(c) (f * g)(x):

(f * g)(x) is not specified. Please provide the correct operation to perform.

(d) ()(x) is not specified. Please provide the correct function to perform the operation.

Part 2: Compositions of Functions

3. Given f(x) = x², g(x) = 5x, and h(x) = x + 4, we can find the value of f[h(-9)] as follows:

f[h(-9)] = f(-9 + 4) = f(-5) = (-5)² = 25

4. Given f(x) = x², g(x) = 5x, and h(x) = x + 4, we can find the value of h∘f(4) as follows:

h∘f(4) = h(f(4)) = h(4²) = h(16) = 16 + 4 = 20

5. Given f(x) = x², g(x) = 5x, and h(x) = x + 4, we can find the value of g[h(-2)] as follows:

g[h(-2)] = g(-2 + 4) = g(2) = 5(2) = 10

6. The formula f = converts inches n to feet f, and m = 5280 converts feet to miles m. The composition of functions that converts inches to miles can be written as m∘f, where m is applied first and then f.

m∘f(n) = m(f(n)) = m(n/12) = n/(12*5280)

Part 3: Inverses of Functions

7. Given f = {(-4,-5), (0,3), (1,6)} and g = {(6,1), (-5,0), (3,-4)}, we can find fg and g∘f, if they exist.

(a) fg:

To find fg, we need to perform the composition of functions fg(x) = f(g(x)).

fg(x) = f(g(x)) = f(1

) = 6

(b) g∘f:

To find g∘f, we need to perform the composition of functions g∘f(x) = g(f(x)).

g∘f(x) = g(f(x)) = g(x²) is not defined since there is no mapping for x² in g.

8. Given g(x) = x + 6 and h(x) = 3x², we can find [gh](x) and [hg](x), if they exist.

(a) [gh](x):

To find [gh](x), we need to perform the composition of functions [gh](x) = g(h(x)).

[gh](x) = g(h(x)) = g(3x²) = 3x² + 6

(b) [hg](x):

To find [hg](x), we need to perform the composition of functions [hg](x) = h(g(x)).

[hg](x) = h(g(x)) = h(x + 6) = 3(x + 6)² = 3(x² + 12x + 36) = 3x² + 36x + 108

9. To find the inverse of the relation {(-5,-4), (1,2), (3,4), (7,8)}, we need to swap the x and y values to obtain the inverse relation:

Inverse relation: {(-4,-5), (2,1), (4,3), (8,7)}

10. To find the inverse of the function g(x) = 3 + x, we need to interchange x and y and solve for y:

y = 3 + x

Interchanging x and y:

x = 3 + y

Solving for y:

y = x - 3

The inverse function of g(x) = 3 + x is g^(-1)(x) = x - 3.

Graphically, the function g(x) = 3 + x and its inverse g^(-1)(x) = x - 3 can be represented by plotting the points and reflecting them across the line y = x.

Step-by-step explanation:

The y intercept is the value when x =0

We can find the slope using

m = (y2-y1)/(x2-x1)

m = ( 11-9)/(2-1)

   = 2/1

  = 2  

Answer:

Based on these observations, the inequality represented by the graph is y > mx + b, where m is a positive number and b is a negative number.

Step-by-step explanation:

The graph represents a linear function. To find the inequality, we can find the equation of the line in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.

From the graph, it can be seen that the slope of the line is positive, which means that as x increases, y also increases. Also, the y-intercept is negative, which means that the line crosses the y-axis at a negative value.

Based on these observations, the inequality represented by the graph is y > mx + b, where m is a positive number and b is a negative number.

Note that the exact values of m and b can be found by using two points on the line and solving for the slope and y-intercept using the formula for a line.
