Answer:
i believe it's (1,-8)
Step-by-step explanation:
you subtract the "+3," since it's really the opposite, from 4 to get 1. The -8 stays the same since the transformation doesn't affect the y's.
Find all relative maximum and minimums of f(x) =2x^3-3x^2-12x+5 Explain your steps in detail.
Answer:
The relative minimum is (3,-4) and the relative maximum is (-2,1)
Step-by-step explanation:
The first step is to take the derivative of f(x)
By using the power rule which is d/dx x^n=nx^n-1 you will find that the derivative is 6x^2-6x-12
The next step is to set the derivative = to 0 and by doing that you will obtain x being equaled to -2 and 3
Put -2 and 3 on a sign chart and determine the behavior for both of those functions
The outcome of your sign chart should be + - + because of the odd multimplicity of (x-3) and (x+2).
The next step is to find the f(x) values or y values of your two points
By plugging in 3 into f(x), you get -4 and by plugging in -2 into f(x) you get 1
Since there was interval given, I cannot find the absolute extremas of this function.
Evaluate the piecewise function by matching the domain values with the range values.
The subfuctions of the piecewise function f(x) are linear functions
The matching values of the domain values with the range values are
x f(x)
-4 -7
-2 -8
0 -2
2 4
4 -4
8 -12
How to evaluate the piece-wise function?The function is given as:
[tex]f(x) = \left[\begin{array}{cc}x-3&x\le-4\\3x-2&-4 < x\le 2\\-2x+4&x > 2\end{array}\right][/tex]
The above definition means that:
All x values less than or equal to -4 would be evaluated using f(x) = x - 3All x values greater than -4 but less than or equal to 2 would be evaluated using f(x) = 3x - 2All x values greater than 2 would be evaluated using f(x) = -2x + 4Using the above highligts, we have:
f(-4) = -4 - 3 = -7
f(-2) = 3(-2) - 2 = -8
f(0) = 3(0) - 2 = -2
f(2) = 3(2) - 2 = 4
f(4) = -2 * 4 + 4 = -4
f(8) = -2 * 8 + 4 = -12
So, the matching values are
x f(x)
-4 -7
-2 -8
0 -2

4 -4
8 -12

Form a polynomial whose zeros and degree are given. Zeros: 2, multiplicity 1; 4, multiplicity 2; degree 3
Answer:
If the polynomial is degree 3, then it is of the form y = Ax3 + Bx2 +Cx + D
And if the zeros are -2 with multiplicity of 1, then the factor is (x+2)1 = x+2
The other zero is -4 with multiplicity of 2, so it's factor is (x+4)2 = x2 +8x+16
So in general, if we let A = 1, then the polynomial is y = (x+2)(x+4)2 which multiplies out to
(x+2)(x2+8x+16) = x3 + 8x2 + 16x + 2x2 + 16x + 32
Combining like terms gives the polynomial:
y = x3 +10x2 + 32x + 32
If A is not 1, then y = A(x3 +10x2 + 32
I WILL GIVE YOU 20 POINTS TO THOSE WHO ANSWER THIS QUESTION RIGHT NOOOO SCAMS AND EXPLAIN WHY THAT IS THE ANSWER. A ramp formed the angles shown to the right. What are the values of A and B?
Answer:
A=167⁰, B=13⁰
Step-by-step explanation:
A=167⁰
B=13⁰
I HOPE IT HELPED YOU
Answer:
a° = 167°, b° = 13°
Step-by-step explanation:
since the angles in a triangle add to 180°, we can work out b°
90° (right angle) - 77° = 167°
180° - 167° = 13°
since the angle of a straight line is also 180°, a° would be 180° - 13° which is 167°.

The change that will occur to the mean, median, mode of the data matched as follows:
1. e
2. b
3. d

5. c
What is the Mean fo a Data Set?To find the mean, the sum of all the values is divided by the number of values.
Given the data, 90, 85, 35, 70, 67, 76, 90, 79, 94, 100, 87, 61, 56, 80, 67, 65, therefore:
1. 35 is an extreme value, so it is an outlier. If we remove 35, the greatest change will be on the mean. (e)
2. If we remove 90, 67 will have the highest frequency. This means the mode of the data will change to 67. (b)
3. If 76 is removed from the data, the median of the data would be 79. (d)
4. If we remove 100, the range of the data would be, 94 - 35 = 59. (a)
5. If we remove 94, the mean of the data = 1108/15 = 73.87
This means the mean of the data will change to 73.87 if we remove 94. (c)

The following statement is a Contingency: (P and (P => Q)) => Q T True F False
The statement (p and (p => q)) => q) is not a contingency because of it evaluating to only true while a contingency statement includes both true values and some false values.
What is a contingency statement?Contingency is a statement in which there are some true and some false values for every value of its propositional variables.
The statement given is (p and (p => q)) => q), or in more symbolic way, it is: ((p ∧ (p → q)) → q)
Now, let we evaluate it for p = False, and q = False.
Then we get:
(p → q) = T (as False implied False)
Now, (p ∧ (p → q)) is F and T which is F
Then, ((p ∧ (p → q)) → q) is F → F which is True, or T.
Thus, p = F,and q = F makes ((p ∧ (p → q)) → q) = T
Similarly, the truth table for the statement (p and (p => q)) => q) or simply ((p ∧ (p → q)) → q) is:
p q ((p ∧ (p → q)) → q)
F F T
F T T
T F T
T T T
Since all the values are true, thus, this isn't a contingency.
Thus, the statement (p and (p => q)) => q) is not a contingency because of it evaluating to only true while a contingency statement includes both true values and some false values.
