Step-by-step explanation:

D. 8x^5y^4

1. HP price for Susie is R 282600 and David is R 179300

2. The difference between the total price paid by Susie and David  is R 103300

3. The interest that Susie and David have to pay as a percentage of the cash price​ is 117.38% and 37.92%

The HP price, also known as the hire purchase price, is the total amount that a buyer pays for a product when purchasing it through a hire purchase agreement.

It includes the cash price of the product plus any interest and fees charged by the lender.

Here we have

3.1.1, For Susie:

The cash price of the car is R 130000.

She pays a 10% deposit, which is:

= [10/100] × 130000 = R 13000

=> HP price =  the cash price - the deposit

=>  130000 -  13000 = R 117000

She will pay monthly installments of R 4600 for 3 years,

which is 36 months.

Therefore, the total amount she will pay is:

36 x 4600 = R 165600

Therefore, the total amount she will pay is R 165600

The HP price for Susie is,  

117000 + 165600 = R 282600

For David:

The cash price of the car is R 130000. He pays a 35% deposit, which is:

=> [ 35/100] × 130000 = R 45500

The HP price = 130000 - 45500 = 84500

He will pay monthly installments of R 3950 for 2 years, which is 24 months. Therefore, the total amount he will pay is:

24 × 3950 = 94800

The HP price for David is, therefore:

=> 84500 + 94800 = R 179300

3.1.2, The difference between the total price paid by Susie and by David  

=  282600 - 179300 = R 103300

3.1.3

For Susie:

The total interest she has to pay is the difference between the HP price and the cash price, which is:

=> 282600 - 130000 = R 152600

The interest rate as a percentage of the cash price is:

=> (152600/130000) × 100% = 117.38%

For David:

The total interest he has to pay is the difference between the HP price and the cash price, which is:

=> 179 300 - 130 000 = R 49 300

The interest rate as a percentage of the cash price is:

=> (49 300/130000) × 100% = 37.92%

Therefore,

1. HP price for Susie is R 282600 and David is R 179300

2. The difference between the total price paid by Susie and David  is R 103300

3. The interest that Susie and David have to pay as a percentage of the cash price​ is 117.38% and 37.92%

By applying synthetic division concept, it can be concluded that if f(v) = 8v⁴ + 34v³ - 26v² + 21v + 11, then, f(-5) = 6.

Synthetic division is a shorthand way of dividing polynomials where we can divide the coefficients of the polynomial by omitting variables and exponents. As a result, we get the coefficient of the quotient and the remainder.

Polynomial remainder theorem states that the value of p in argument b is equal to the remainder of the polynomial division p(x) / (x - b). Specifically, p(x) is divided by x - b with a remainder of zero if, and only if, b is a root of p.

We have the following polynomial:

f(v) = 8v⁴ + 34v³ - 26v² + 21v + 11

To find f(-5) using synthetic division, we will divide the polynomial f(v) by (z + 5). The steps are as follows:

1. Put the coefficients in a row and multiply the outside coefficient by the divisor: 8(-5)= -40.

2. Add the inside coefficient to the product from the previous step: -40 + 34 = -6.

3. Multiply the result from the previous step by the divisor: -6(-5) = 30.

4. Add the next coefficient to the product from the previous step: 30 - 26 = 4.

5. Multiply the result from the previous step by the divisor: 4(-5) = -20.

6. Add the next coefficient to the product from the previous step: -20 + 21 = 1.

7. Multiply the result from the previous step by the divisor: 1(-5) = -5.

8. Add the last coefficient to the product from the previous step: -5 + 11 = 6.

The final result of the synthetic division is 6, so the answer to the question is f(-5) = 6.

The Cartesian equation of the curve is y = 0. This is a horizontal line at y = 0.

To find the Cartesian equation of the curve, we need to eliminate the parameter θ from the parametric equations.

First, let's rearrange the first equation to isolate θ:
2x = cotθ - cscθ
2x + cscθ = cotθ
cscθ - cotθ = -2x
1/(sinθ) - 1/(tanθ) = -2x
1/(sinθ) - (cosθ)/(sinθ) = -2x
(cosθ)/(sinθ) = 1/(sinθ) + 2x
cosθ = 1 + 2x*sinθ

Now, let's rearrange the second equation to isolate θ:
4y = 2cscθ - 2cotθ
2y = cscθ - cotθ
2y + cotθ = cscθ
cotθ - cscθ = -2y
1/(tanθ) - 1/(sinθ) = -2y
(cosθ)/(sinθ) - 1/(sinθ) = -2y
(cosθ)/(sinθ) = 1/(sinθ) - 2y
cosθ = 1 - 2y*sinθ

Now we can set the two equations equal to each other and solve for sinθ:
1 + 2x*sinθ = 1 - 2y*sinθ
4x*sinθ = -4y*sinθ
sinθ = -4y/4x
sinθ = -y/x

Finally, we can use the Pythagorean identity, sin^2θ + cos^2θ = 1, to find the Cartesian equation:
(-y/x)^2 + cos^2θ = 1
y^2/x^2 + cos^2θ = 1
cos^2θ = 1 - y^2/x^2
cosθ = √(1 - y^2/x^2)

Substituting this back into one of the original equations, we get:
1 + 2x*sinθ = 1 - 2y*sinθ
1 + 2x*(-y/x) = 1 - 2y*(-y/x)
1 - 2y^2/x = 1 + 2y^2/x
4y^2/x = 0
y^2 = 0
y = 0

So the Cartesian equation of the curve is y = 0. This is a horizontal line at y = 0.

The domain of a function is the set of all possible input values (x) for which the function is defined.

The range of a function is the set of all possible output values (f(x)) that the function can produce.

For the given function f(x) = 2^(x+1), the domain includes all real numbers because we can substitute any real number for x and obtain a valid output.

To find the range, we can examine the behavior of the function as x approaches positive and negative infinity. As x approaches negative infinity, the exponent (x+1) becomes very large negative number, and 2^(x+1) approaches zero. As x approaches positive infinity, the exponent (x+1) becomes very large positive number, and 2^(x+1) approaches infinity. Therefore, the range of the function is (0, infinity).

So, the domain is (-infinity, infinity) and the range is (0, infinity).

The factors which would be considered while constructing a road for a steep slope are the terrain of the area, the estimated daily traffic, minimum and maximum sight distance, and the design speed.

Constructing roads on a steep slope is a challenge for every civil engineer. It is because such slopes which are possibly found in hilly areas have less access to main land from where the resources/ material for construction are to be transported and also need specific calculations to estimate maximum durability of the roads and also prevent accidents which might occur due to steep slopes.

Hence, an engineer has to keep in mind several factors which can help to reduce the accident cases, provide road safety and better connectivity with major areas.  It is essential that roadway engineers design roads that allow drivers to travel at the right speed. Topography determines the terrain, the different gradient and the construction cost.

A square is a regular quadrilateral in Euclidean mathematics because it has four equal sides and four equal angles (right angles, 90-degree angles). It can also be explained as a rectangle with two adjacent sides that are of identical length. It is the only regular polygon whose diagonals are all the same length and whose internal, central, and exterior angles are all equal (90°).

In mathematics, an angle bisector is a line that divides an angle into two equal angles. The term "bisector" refers to a device that divides an object or a shape into two equal sections. An angle bisector is a beam that divides an angle into two identical segments of the same length.

Angle bisector points are equally spaced from both angle lines.

Any angle, including acute, obtuse, and right angles, can have an angle bisector traced to it.

In the given square,

The diagonals NL and KM are angle bisectors of ∠K, ∠L, ∠M and ∠N.

Therefore, ∠OKL= 90/2

2. Symmetry with respect to the x-axis (odd symmetry). 3. Symmetry with respect to the origin (rotational symmetry)

To check for symmetry with respect to the y-axis, we can substitute (-x) for x in the function and see if it is equal to the original function.

f(-x)=-3(-x)^(2)+4=-3x^(2)+4

The mode of the set {2, 5, 6, 8, 9, 11, 15} is the number that appears most frequently in the set. In this case, all of the numbers appear only once, so there is no mode.

The mode of a set of numbers is the value that appears most frequently in the set. To find the mode of the set {2, 5, 6, 8, 9, 11, 15}, we need to count how many times each number appears and then determine which number appears most frequently.

From the set, we can see that no number appears more than once. Therefore, there is no single number that appears most frequently and we cannot determine a mode for this set.

In some cases, a set of numbers may have multiple modes if two or more numbers appear with the same frequency. For example, the set {1, 2, 2, 3, 3, 3, 4, 5, 5} has two modes, 2 and 3, since both of these numbers appear three times in the set.

However, in the case of the set {2, 5, 6, 8, 9, 11, 15}, there are no repeating numbers, so there is no mode.

The colour determines every consequence that can occur when drawing a marble. The total number of marbles is 15, including 7 orange and 8 blue. Hence, there are 7+5=15 elements in the sample space.

As we are interested in drawing an orange marble and returning the orange marble to the urn after each drawing, the number of favourable events, in this case, is 7. Due to their independence, past drawings won't have an impact on the most recent ones. The likelihood of an event P(A) = total outcomes / favourable outcomes can be used to define A as the ratio of the number of favourable outcomes to the number of total outcomes in the sample space.

We have,

To find a formula for the exponential function passing through the points (-2, 768) and (2, 3), we can use the general form of an exponential function: y = a x [tex]b^x[/tex], where "a" is the initial value or y-intercept, and "b" is the base of the exponential function.

Let's start with the first point (-2, 768).

Plugging in the values, we have:

768 = a x [tex]b^{-2}[/tex]

Next, let's consider the second point (2, 3).

Plugging in the values, we have:

3 = a x b²

Now we have a system of equations:

768 = a x [tex]b^{-2}[/tex]

3 = a x b²

To solve this system, we can divide the second equation by the first equation:

3/768 = (a x b²) / (a x [tex]b^{-2}[/tex])

Simplifying further:

3/768 = [tex]b^4[/tex]

Taking the fourth root of both sides:

[tex](b^4)^{1/4} = (3/768)^{1/4}\\b = (3/768)^{1/4}[/tex]

Now we can substitute the value of b back into either of the original equations to solve for a.

Let's use the first equation:

[tex]768 = a \times b^{-2}[/tex]

Substituting [tex]b = (3/768)^{1/4}:[/tex]

[tex]768 = a \times ((3/768)^{1/4})^{-2}[/tex]

Simplifying:

[tex]768 = a \times (3/768)^{-1/2}[/tex]

Now, we can simplify the right-hand side:

[tex]768 = a \tmes (768/3)^{1/2}[/tex]

Simplifying further:

[tex]768 = a \times (256)^{1/2}[/tex]

Taking the square root of 256:

768 = a x 16

Solving for a:

a = 768 / 16 = 48

(2√(4x-28))2 = (x - 6)2

Then, solve for x:

(4x-28) = (x - 6)2
4x-28 = x2 - 12x + 36
x2 - 16x + 64 = 0

Solve for x by factoring:

(x-8)(x-8) = 0

x = 8

Therefore, the solution to the equation x = 6+((4x-28)1/2) is x = 8.
