WILL GIVE BRAINLIEST !!! What is the axis of symmetry for the function, f(x) = −2(x − 4)2 + 2 ?
Answers
Answer:
\(x=4\)
Step-by-step explanation:
We have the function:
\(f(x)=-2(x-4)^2+2\)
This is a quadratic in vertex form:
\(f(x)=a(x-h)^2+k\)
Where (h, k) is the vertex.
So, according to the equation, h=4 and k=2.
Hence, our vertex is at (4, 2).
Remember that the axis of symmetry is the vertical line that passes through the x-coordinate of the vertex.
Hence, our axis of symmetry is x=4.

What is substitution method?The algebraic approach to solving simultaneous linear equations is known as substitution method. The value of one variable from one equation is substituted in the second equation in this procedure, as the name implies.Finding the value of any variable from one equation in terms of another variable is the first step in the substitution method. For instance, if there are two equations,-2x – y = -7 and x + 7y = 10, Applying the replacement approach begins with this.One of the equations' initial variable should be solved for, and the answer should be inserted into the other equation.Form of Point: (3 , 1 )

(a) write an equation of the line that passes through the point and is parallel to the given line
(b) write an equation of the line that passes through the point and is perpendicular to the given line
Answers
Answer:
(a) Equation of parallel line is y = x + 4
(b) Equation of perpendicular line is y = - x + 8
Step-by-step explanation:
Given line is
x - y = 4
Rewrite this as
x - 4 = y
or
y = x - 4
This is the equation of a line in slope intercept form which is generally
y = mx + b
where m is the slope and b the y-intercept
Here m = 1, b = -4
(a) A parallel line will have the same slope but a different y-intercept
So for starters we can write the equation of the parallel line as
y = x + b
Since this passes through (2,6) sub 2 for x and 6 for y to get
6 = 2 + b
==> b = 4
Equation of the line is
y = x + 4
(b) A perpendicular line will have as slope -1/m where m is the slope of the original line
Here m = 1, so -1/m = -1/1 = -1
Equation will be of the form
y = -x + b
Since this also passes through (2,6)
6 = -2 + b
==> b = 6 + 2 = 8
Equation of perpendicular line is
y = -x + 8

Step-by-step explanation:To evaluate the expression (2b+3a)×(c^2) when a=4, b=3, and c=1/3, we substitute the given values into the expression and perform the indicated arithmetic operations:
(2b + 3a) × (c^2)
= (2(3) + 3(4)) × ((1/3)^2) (substitute a=4, b=3, c=1/3)

Answers
The correct answer is C. It is the graph of f(x) translated 11 units to the left.
The correct answer is:
C. It is the graph of f(x) translated 11 units to the left.
When we have a function of the form g(x) = f(x - a), it represents a horizontal translation of the graph of f(x) by 'a' units to the right if 'a' is positive and to the left if 'a' is negative.
In this case, g(x) = f(x - 11), which means that the graph of f(x) is being translated 11 units to the right. However, the answer options do not include this specific transformation. The closest option is option C, which states that the graph of g(x) is translated 11 units to the left.
The graph of f(x) = x is a straight line passing through the origin with a slope of 1. If we apply the transformation g(x) = f(x - 11), it means that we are shifting the graph of f(x) 11 units to the right. This results in a new function g(x) that has the same shape and slope as f(x), but is shifted to the right by 11 units.
Therefore, the correct answer is C. It is the graph of f(x) translated 11 units to the left.

Let u(x) = sin(x) and v(x) = x ^ 14 and f(x) = (u(x))/(v(x))
Answers
Explanation:
Step 1. We are given the expressions for u(x) and v(x):
\(\begin{gathered} u(x)=sin(x) \\ v(x)=x^{14} \end{gathered}\)The first two parts of the problem consist of finding the derivative of these two expressions: u'(x) and v'(x).
Step 2. To derivate u(x) we use the following rule:
\(\begin{gathered} for\text{ a function } \\ g(x)=sin(x) \\ The\text{ derivative is} \\ g^{\prime}(x)=cos(x) \end{gathered}\)which means that in this case:
\(\boxed{u^{\prime}(x)=cos(x)}\)Step 3. To derivate v(x) we use the following rule:
\(\begin{gathered} for\text{ a function} \\ g(x)=x^n \\ The\text{ derivative is} \\ g^{\prime}(x)=nx^{n-1} \end{gathered}\)In our case n=14, therefore, the derivative is:
\(\begin{gathered} v(x)=x^{14} \\ \downarrow \\ v^{\prime}(x)=14x^{14-1} \end{gathered}\)simplifying the exponent:
\(\boxed{v^{\prime}(x)=14x^{13}}\)Step 4. Now, to solve the third part of the problem, we consider the definition of f(x) given in the statement:
\(f(x)=\frac{u(x)}{v(x)}\)And to find the derivative of this function f'(x) or f', we use the quotient rule,
\(f^{\prime}=\frac{u^{\prime}v-uv^{\prime}}{v^2}\)We already know u and v from the given definitions, and we found u' and v' in 2 and 3.
So now, we substitute the known values into the quotient rule formula:
\(f^{\prime}=\frac{cos(x)(x^{14})-sin(x)(14x^{13})}{(x^{14})^2}\)Step 5. The last step is to simplify our result. We start by simplifying the exponent in the denominator:
\(f^{\prime}=\frac{cos(x)(x^{14})-s\imaginaryI n(x)(14x^{13})}{x^{28}}\)and to simplify further, divide both the numerator and denominator by x^13
\(\begin{gathered} f^{\prime}=\frac{cos(x)(x^)-s\imaginaryI n(x)(14)}{x^{15}} \\ \downarrow \\ \boxed{f^{\prime}=\frac{xcos(x)-14sin(x)}{x^{15}}} \end{gathered}\)And that is the simplified solution.
Answer:
\(\begin{gathered} u^{\prime}(x)=cos(x) \\ v^{\prime}(x)=14x^{13} \\ f^{\prime}=\frac{xcos(x)-14s\imaginaryI n(x)}{x^{15}} \end{gathered}\)Identify the steps to find the value of the inverse ( Please show your work thank you) ↓

If f(x)=x^3−5x^2−2x+24 and (x+2) is a factor, what are the remaining factors?
Factor 1:
Factor 2:
Factor 3:
Answers
Answer:
(x+2), (x-4), (x-3)
Step-by-step explanation:
Use the rational root theorem to get started, then factor the remaining quadratic to find:
x^3 − 5x^2 − 2x + 24 = (x + 2)(x − 4)(x − 3)
Explanation:
Let f(x) =x^3 − 5x^2 − 2x + 24
By the rational root theorem, any rational zeros of f(x) must be expressible in the for p/q for integers p, q with p a divisor of the constant term 24 and q a divisor of the coefficient 1 of the leading term.
That means that the only possible rational zeros are the factors of 24, namely:
± 1, ± 2, ± 3, ± 4, ± 6, ± 12, ± 24
Try each in turn:
f(1) = 1 − 5 − 2 + 24 = 18
f(−1) = −1 − 5 + 2 + 24 = 20
f(2) = 8 − 20 − 4 + 24 = 8
f(−2) = −8 − 20 + 4 + 24 = 0
So x = −2 is a zero and (x + 2) is a factor.
x^3 − 5x^2 − 2x + 24 = (x + 2)(x^2 − 7x + 12)
We can factor
x^2 − 7x + 12 by noting that 4 × 3 = 12 and 4 + 3 = 7, so:
x^2 − 7x + 12 = (x − 4)(x − 3)
Putting it all together:
x^3 − 5x^2 − 2x + 24 = (x + 2)(x − 4)(x − 3)
Find the smallest whole number by which 16087 should be multiplied or divided to get a perfect square
Answers
There is no whole number by which you can multiply or divide 16087 to make it a perfect square.
To determine by which number you should multiply or divide 16087 to make it a perfect square, we can analyze its prime factorization. The prime factorization of 16087 is 13 × 1237.
In order to make 16087 a perfect square, we need each prime factor to have an even exponent. However, when we examine the prime factors of 16087, we find that both 13 and 1237 have an exponent of 1.
To make the exponents even, we need to multiply or divide 16087 by additional prime factors and their respective exponents. However, since 16087 is a product of two prime numbers (13 and 1237), we cannot introduce any additional prime factors to make the exponents even.
A perfect square is a number that can be expressed as the product of two equal factors. In the case of 16087, it cannot be transformed into a perfect square by multiplying or dividing by any whole number. The prime factors 13 and 1237 remain with an exponent of 1 each, indicating that there is no integer that can be applied to make them equal and convert 16087 into a perfect square.
Therefore, there is no whole number by which you can multiply or divide 16087 to make it a perfect square.

can you simplify this: 1/3(5x-8)+2/3x

Step-by-step explanation:
To simplify this expression, you need to distribute the 1/3 to the expression inside the parenthesis. This gives:
1/3(5x-8) = (1/3)*5x - (1/3)*8 = (5/3)x - (8/3)
Now, you can distribute the 2/3 to the x-term:
2/3x = (2/3)x
Putting the two terms together, you get:
(5/3)x - (8/3) + (2/3)x = (5/3 + 2/3)x - 8/3 = (7/3)x - 8/3
