The table shows three values of x and their corresponding values of f (x) for a linear function f, such that f (r) = 0 and f (0) = s, where r and s are constants. What is the value of rs?
Using a linear function, it is found that the product rs is rs = 81.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem, when x changes by 68(from -64 to 68), y changes by -16(from 12 to -4), hence the slope is given by:
m = -16/64 = -0.25.
Hence:
y = -0.25x + b.
When x = 34, y = -4, hence this is used to find b.
-4 = -0.25(34) + b
b = 4.5.
Hence the function is:
y = -0.25x + 4.5.
f(r) = 0, hence:
-0.25x + 4.5 = 0
x = 4.5/0.25
x = 18
r = 18.
f (0) = s, hence s = 4.5.
Then the value of the product is:
rs = 18 x 4.5 = 81.

Let V(x)=−x2+2x−4 and W(x)=−x3+2x2+x+5. Find V(x)⋅W(x)
Answer:
B
Step-by-step explanation:
I assume this should look like
V(x) = -x² + 2x - 4
W(x) = -x³ + 2x² + x + 5
when doing arithmetic operations with whole functions, we simply do these operations with the whole expressions :
V(x) × W(x) =
(-x² + 2x - 4) × (-x³ + 2x² + x + 5) =
= x⁵ - 2x⁴ - x³ - 5x² - 2x⁴ + 4x³ + 2x² + 10x + 4x³ - 8x² - 4x - 20 =
= x⁵ - 4x⁴ + 7x³ - 11x² + 6x - 20

A researcher is examining the claims made by a water softener salt manufacturer. He performs an experiment using water from a variety of sources. For each water source, he has a sample with no treatment and a sample treated with the recommended amount of the water softener salt.
He then tests each sample to measure the softness and compares the results, determining that the claims made by the manufacturer are true.
The conclusion drawn from the study is _____ because the sample is _____. In this instance, an ______study was performed.
The conclusion is valid in this experiment because the sample is homogenous and an experimental study was performed.
What is an experimental study?It should be noted that an experimental study is one in which there is a dependent variable and there is a dependent variable. Also a control is used to establish the validity of the results.
In this case, the dependent variable is the level of softness after treatment while the independent variable is the type of water softener used.

A. 60°
B. 45°
C. 180°
D. 90°
Answer:
C. 180°
Step-by-step explanation:

If m < ACD = 100 , then m < ACE = ?
If m ∠ACD = 100°, then m ∠ACE = 80°, as ∠ACD and ∠ACE are supplementary angles.
Supplementary angles are the angles whose sum is equal to 180°. The angles formed when one straight line intersects the other, on the point of intersection on the same side of any line are always supplementary.
In the given question, AB and DE are two straight lines intersecting at point C. ∠ACD and ∠ACE lie on the same side of the line DE, thus they are supplementary angles.
Therefore, m ∠ACD + m ∠ACE = 180°.
But we know that m ∠ACD = 100°. So,
m ∠ACD + m ∠ACE = 180°,
or, 100° + m ∠ACE = 180°,
or, m ∠ACE = 180° - 100° = 80°.
Therefore, if m ∠ACD = 100°, then m ∠ACE = 80°, as ∠ACD and ∠ACE are supplementary angles.

Select each graph that shows a function and it’s inverse
Answer:
First option
Explanation:
The inverse of a graph is its reflection on the line y = x.
This means that it is the graph that you get by reflecting the original graph on a line with the equation y = x.
In the picture below, we can see a function (red graph), its inverse (blue graph) and the line (green) that the two graphs are reflected on.
From the picture below, we can see that the shapes of the graph of a function and its inverse is similar and correspond to the shape given as the first option in the question. Therefore, the first option is the answer.

Complete the equation: x2−4x+−−=(−−)2
The complete equation is x^2 - 4x + (-2) = (-2)^2
How to complete the equation?The equation is given as:
x^2 - 4x + __ = (__)^2
_____________________________
Take the coefficient of x
k = -4
Divide by 2
k/2 = -4/2
k/2 = -2
Square both sides
(k/2)^2 = (-2)^2
_____________________________
Add the result of the above computation to both sides of x^2 - 4x + __ = (__)^2
So, we have:
x^2 - 4x + (-2) = (-2)^2

What is the length of focal chord of the equation y^2 + 6y - 2x + 13 = 0?
Answer:
2 units
Step-by-step explanation:
The given equation graphs as a parabola that opens to the right. It can be written in the form ...
(4p)x = ay² +by +c
Interpreting the equationWhen the equation is written in the form ...
(4p)x = ay² +by +c
The value of p is the focus-to-vertex distance. The length of the latus rectum (focal chord) is 4 times the value of p, so is the coefficient of x in the equation.
ApplicationRewriting the given equation to the form shown above, we have ...
2x = y² +6y +13
That is, the value of 4p, the coefficient of x, is 2. The length of the focal chord is 2 units.
