The tangent lines of the cubic function f(x) = x(x - 2)(x - 6) at the zeros 0, 2 and 6 are y = 12x, y = -8x + 16 and y = 24x - 144
Part A: The tangent lines of f(x) = x(x - 2)(x - 6)The cubic function is given as:
f(x) = x(x - 2)(x - 6)
Expand
f(x) = x³ - 8x² + 12x
Differentiate the function
m = 3x² - 16x + 12
At the point x = 0, we have:
m = 3(0)² - 16(0) + 12
m = 12
Also, we have:
f(0) = 0
A linear equation is represented as:
y = m(x - x₁) + y₁
So, we have:
y = 12(x - 0) + 0
y = 12x
At the point x = 2, we have:
m = 3(2)² - 16(2) + 12
m = -8
Also, we have:
f(2) = 0
A linear equation is represented as:
y = m(x - x₁) + y₁
So, we have:
y = -8(x - 2) + 0
y = -8x + 16
At the point x = 6, we have:
m = 3(6)² - 16(6) + 12
m = 24
Also, we have:
f(6) = 0
A linear equation is represented as:
y = m(x - x₁) + y₁
So, we have:
y = 24(x - 6) + 0
y = 24x - 144
The above means that the tangent lines are:
y = 12x, y = -8x + 16 and y = 24x - 144
From the attached graph, we can see that the tangent lines at the zero values x = 0 and x = 2 intersect the graph of f(x) at the zero value x = 6
Part B: The tangent lines of f(x) = (x - a)(x - b)(x - c)The equation is given as:
f(x) = (x - a)(x - b)(x - c)
To prove the statement using a computer algebra system, simply follow the next steps:
Set values for a, b and cInclude the following vertices in the plane: (a,f(a)), (b,f(b)) and (c,f(c))Differentiate f(x) i.e g(x) = f'(x)Include the following vertices in the plane: (a,g(a)), (b,g(b)) and (c,g(c))Lastly, plot the following equations: y = g(a)(x - a) + f(a), y = g(b)(x - b) + f(b) and y = g(c)(x - c) + f(c)See attachment (2) for proof

Which linear equation best represents the line of best fit for the scatterplot?
y = − 1/3x
y= 3x
y=−3x
y = 1/3x
Answer:
[tex]y = -\frac{1}{3}x[/tex]
Step-by-step explanation:
The scatter plot trends downward from left-> right, meaning that it is negative. Next, use two points to solve for the value for the slope.
In this case, I will use (-3 , 1) & (0 , 0)
Use the following equation. m = slope:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Let:
[tex](x_1 , y_1) = (0 , 0)\\(x_2 , y_2) = (-3 , 1)[/tex]
Plug in the corresponding numbers to the corresponding variables:
[tex]m = \frac{1 - 0}{-3 - 0} = \frac{1}{-3} = -\frac{1}{3}[/tex]
Your answer will be:
[tex]y = -\frac{1}{3}x[/tex]

In the equation model, the simple harmonic motion is d=6sin(πt/4)-6 if the object moves in simple harmonic motion with a period of 8 seconds and amplitude of 6 cm.
What is simple harmonic motion?Simple Harmonic Motion is described as a motion in which the restoring force is proportionate to the body's displacement from its mean position.
We have:
Amplitude A = 6 cm
Time period = 8 seconds

Things we need to keep in mind in order to plot a point :
x - coordinate of the point shows its distance from origin in horizontal direction. y - coordinate of the point shows its distance from origin in vertical direction.Signs of the coordinates shows which side it lies on.
if x coordinate is positive then the point lies on right side of y - axis and if it is negative then it lies on left side of y - axis.similarly,
if y coordinate is positive then the point lies above the x - axis , and if it's negative then it lies on down the x - axis.Now, let's proceed ~
First check out its x - coordinate on origin and move up or down according to its y - coordinate and you will get your required point.
So, for point (1 , 0) it has y - coordinate = 0, so it lies on x - axis at the x - coordinate of 1.
Vanessa bought a house for $268,500. she has a 30 year mortgage with a fixed rate of 6.25%. vanessa’s monthly payments are $1,595.85. how much was vanessa’s down payment?
Based on the calculation below, the amount of vanessa’s down payment is $9,314.45.
Calculation of down paymentFirst, we have to calculate the balance after deducting vanessa’s down payment using the formula for calculating the present value (PV) of an ordinary annuity as follows:
PV = P * ((1 - (1 / (1 + r))^n) / r) …………………………………. (1)
Where;
PV = Present value or balance after deducting vanessa’s down payment = ?
P = Monthly payment = $1,595.85
r = Monthly interest rate = 6.25% / 12 = 0.0625 / 12 = 0.00520833333333333
n = number of months = 30 * 12 = 360
Substitute the values into equation (1), we have:
PV = $1,595.85 * ((1 - (1 / (1 + 0.00520833333333333))^360) / 0.00520833333333333) = $259,185.55
Now, the amount of vanessa’s down payment can be calculated as follows:
Vanessa’s down payment = Cost of the house – PV = $268,500 - $259,185.55 = $9,314.45

The area of the triangle below is 14.25 square feet. What is the length of the base?
Answer:
5.7 feet
Step-by-step explanation:
Given:
[tex]\text{Height of triagle: 5 ft}[/tex]
Formula;
[tex]\text{Area of triangle}= \dfrac{1}{2} \times \text{Base} \times \text{Height}[/tex]
Substitute the height and the area in the formula;
[tex]\implies\text{Area of triangle}= \dfrac{1}{2} \times \text{Base} \times \text{Height}[/tex]
[tex]\implies14.25 = \dfrac{1}{2} \times \text{Base} \times 5[/tex]
Use cross multiplication;
[tex]\implies14.25 = \dfrac{1}{2} \times \text{Base} \times 5[/tex]
[tex]\implies14.25 \times 2= \text{Base} \times 5[/tex]
Simplify the left hand side;
[tex]\implies14.25 \times 2= \text{Base} \times 5[/tex]
[tex]\implies28.5= \text{Base} \times 5[/tex]
Divide both sides of the equation by 5;
[tex]\implies\dfrac{28.5}{5} = \dfrac{\text{Base} \times 5}{5}[/tex]
[tex]\implies \text{Base} = \dfrac{28.5}{5} = 5.7 \ \text{ft}[/tex]
Therefore, the measure of the base is 5.7 feet.
Answer:
5.7 feet
Step-by-step explanation:
The area formula for a triangle: A=(1/2) Base x Height
1. What we know: 14.25=(1/2)Base x 5
2. Now isolate "base" to get the answer. First, divide by 1/2. Dividing by 1/2 is the same as multiplying by 2. Leaves us with: 28.5=Base x 5.
3. The last thing we have to do is divide 5: 5.7=base.
4. To make sure, check with the formula: (1/2) 5.7 x 5=14.25

Which function has a vertex on the y-axis? f(x) = (x – 2)2 f(x) = x(x 2) f(x) = (x – 2)(x 2) f(x) = (x 1)(x – 2)
The function that has a vertex on the y-axis is f(x) = (x - 2)(x + 2)
How to determine the function?For a function to have its vertex on the y-axis, then the coordinate of the vertex must be:
(h,k) = (0,y)
A quadratic function is represented as:
f(x) = (x - h)^2 + k
So, we have:
f(x) = (x - 0)^2 + k
Evaluate
f(x) = x^2 + k
From the list of options, we have:
f(x) = (x - 2)(x + 2)
Expand
f(x) = x^2 - 4
Hence, the function that has a vertex on the y-axis is f(x) = (x - 2)(x + 2)
