The factored form of the polynomial is f(x) = (x + 2)(x + 10)(x - 6) .
The given polynomial is f(x) = x4 + x3 + 2x2 - 22x - 60.
To find the zeros of the polynomial, set f(x) = 0 and solve for x. This gives us the following equation:
x4 + x3 + 2x2 - 22x - 60 = 0
The given zero is -2. To factor the polynomial, use the zero(-2) as one factor. To find the other factors, set (x + 2) = 0 and solve for x. This gives us the following equation:
x3 + 2x2 - 22x - 60 = 0
To solve this equation, use the Quadratic Formula. This gives us two factors, (x + 10) = 0 and (x - 6) = 0. Therefore, the factored form of the polynomial is:
f(x) = (x + 2)(x + 10)(x - 6)

The solution to the system of equations is [tex]x = -3/4 $ and $ y = -3^{1/2}.[/tex] The solution has been obtained by using substitution method.
What is substitution method?
The substitution approach is one approach of solving equation problems. To use the substitution method, obtain an expression for one variable in terms of the second variable using one equation. Replace that variable with that expression in the second equation after that.
We are given system of equations as:
y = -2x - 5
y = 2x - 2
Now, by using the substitution method, we get
⇒-2x - 5 = 2x - 2
⇒-4x = 3
⇒x = -3 / 4
On substituting the value of x in y = 2x - 2, we get
⇒y = 2(-3/4) - 2
⇒y = (-3/2) - 2
⇒y = -7/2
Hence, the solution to the system of equations is[tex]x = -3/4 $ and $ y = -3^{1/2}.[/tex]

Give three points that are equivalent to the polar point (7,40°). Write the three points in polar form, with the angles in degrees.
Three points that are equivalent to the polar point (7,40°) are (7,400°), (7,-320°), and (7,760°). These points are equivalent because they all have the same magnitude of 7, but their angles differ by multiples of 360°.
In polar form, these points are written as:
- (7,400°) = 7cis(400°)
- (7,-320°) = 7cis(-320°)
- (7,760°) = 7cis(760°)
These points are equivalent because the angle in polar coordinates is measured modulo 360°. This means that any angle that differs by a multiple of 360° will be equivalent. For example, 40° is equivalent to 400° because 400° - 40° = 360°. Similarly, -320° is equivalent to 40° because -320° + 360° = 40°, and 760° is equivalent to 40° because 760° - 720° = 40°.
In conclusion, the three points that are equivalent to the polar point (7,40°) are (7,400°), (7,-320°), and (7,760°), and they are written in polar form as 7cis(400°), 7cis(-320°), and 7cis(760°).

As an engineer, you are responsible for building a road
across a very steep slope. What factors would you consider
when building your road and how would you address them
to ensure the road is safe? Explain
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. Every roadway should be built with illuminated raised pavement markings for facilitating safe travel during the night.

A company's production process has 5 steps of preparing, manufacturing, refining, validating, and shipping. Let's say there are 12 preparation stations and 4 manufacturing stations and 2 refining stations and 2 validating stations and 2 shipping stations.
If it is equally likely for a product to be prepared on any of the preparation stations, please find the probability that randomly chosen product was prepared on preparation stations 6, 7, and 8.
Therefore, the probability that a randomly chosen product was prepared on preparation stations 6, 7, and 8 is 0.25, or 25%.
The probability that a randomly chosen product was prepared on preparation stations 6, 7, and 8 can be found using the formula:
P(event) = number of favorable outcomes / total number of possible outcomes
In this case, the number of favorable outcomes is 3, since there are 3 preparation stations that we are interested in (6, 7, and 8). The total number of possible outcomes is 12, since there are 12 preparation stations in total.
So, the probability that a randomly chosen product was prepared on preparation stations 6, 7, and 8 is:
P(event) = 3 / 12
P(event) = 0.25
Therefore, the probability that a randomly chosen product was prepared on preparation stations 6, 7, and 8 is 0.25, or 25%.

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.
In conclusion, the mode of the set {2, 5, 6, 8, 9, 11, 15} is undefined as there are no repeating numbers in the set.

Find a formula for the exponential function passing through the points (-2,768) and (2,3)
The formula for the exponential function passing through the points (-2,768) and (2, 3) is:
[tex]y = 48 \times ((3/768)^{1/4})^x[/tex]
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
Therefore,

The parametric equations of a curve are:
2x= cotθ - cscθ and
4y= 2cscθ - 2cotθ
Find the Cartesian equation ( y = f(x))
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.

If f(v)=8v^(4)+34v^(3)-26v^(2)+21v+11, use synthetic division to find f(-5) Submit
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.

An urn contains 7 orange marbles and 8 blue marbles. A marble is drawn and dropped back in the urn. The marble was orange if another marble is drawn what is the probability that it will be orange
7 / 15 is the probability that it will be orange. A marble drawing is a separate action. In other words, the results of drawing a marble will not be influenced by each other.
We must ascertain the sample space, the number of occurrences in the sample space, and the number of successful outcomes in order to calculate the necessary probability. 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.
Hence, the following is true for the event P(A₀)= total outcomes / favorable outcomes 7 / 15

x = (-b ± √(b^(2) - 4ac))/(2a)
Plugging in the values of a, b, and c into the formula, we get:
x = (-(6) ± √((6)^(2) - 4(-9)(4)))/(2(-9))
Simplifying the equation, we get:
x = (-6 ± √(36 + 144))/(-18)
x = (-6 ± √180)/(-18)
x = (-6 ± 6√5)/(-18)
x = (1 ± √5)/(3)
Therefore, the solutions to the given polynomial equation are x = (1 + √5)/(3) and x = (1 - √5)/(3).

Susie buys a car on hire purchase. The car costs R130 000. She pays a 10% deposit on the cash price and will have to pay monthly instalments of R4 600 for a period of three years. David buys the same car, but chooses another option where he has to pay a 35% deposit on the cash price and monthly instalments of R3 950 for two years.
3.1.1 Calculate the HP price for both options.
3.1.2 Calculate the difference between the total price paid by Susie and by David
3.1.3 Calculate the interest that Susie and David have to pay as a percentage of the cash price
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%
What is the HP price: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%

what are the domain and range of the function f(x)=2^x+1
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).
