Use CER (Claim, Evidence and Reasoning) to answer the following question. Be sure to answer using
complete sentences and proper grammar.
Here are two equations. One defines function m and the other defines function p.
m (x) = x (x + 6)
p(x) = (x+3)² - 9
Are the expressions defining m and p equivalent?
1. State your claim by answering the question. (1 pt)
2. Provide mathematical evidence supporting your claim. (2 pts)
3. Reason about your claim by comparing the vertex and x-intercepts of BOTH functions. (2 pts)
Claim: The expressions defining m and p are not equivalent.
Evidence: To show that the expressions are not equivalent, we can expand both functions and compare them term by term.
Reasoning: We can also compare the vertex and x-intercepts of both functions to further support our claim.
What is CER?CER (Claim, Evidence, and Reasoning) is a framework commonly used in scientific writing and critical thinking to help structure arguments and explanations.
The CER framework is often used in science classrooms to teach students how to write scientific arguments. Here's a breakdown of each component:
Claim: The claim is the main argument or point being made. It should be a concise statement that is clear and specific.
Evidence: Evidence is the information or data that supports the claim. This can include scientific research, experiments, observations, or other types of data.
Reasoning: Reasoning is the explanation of how the evidence supports the claim. It should be a clear and logical explanation that connects the evidence to the claim.
In the given question,
Claim: The expressions defining m and p are not equivalent.
Evidence: To show that the expressions are not equivalent, we can expand both functions and compare them term by term:
m(x) = x(x + 6) = x² + 6x
p(x) = (x + 3)² - 9 = x² + 6x + 9 - 9 = x² + 6x
We can see that both functions have the same terms x² and 6x, but m(x) has an additional term of 0x, while p(x) has an additional constant term of 0. Therefore, the expressions defining m and p are not equivalent.
Reasoning: We can also compare the vertex and x-intercepts of both functions to further support our claim.
The vertex of m(x) is located at (-3, -9), since it is a quadratic function with a leading coefficient of 1, and the x-coordinate of the vertex is given by -b/2a = -6/(2*1) = -3. The vertex of p(x) is also located at (-3, -9), since it is a quadratic function in vertex form.
The x-intercepts of m(x) are 0 and -6, since m(x) is equal to 0 when x = 0 or x = -6. The x-intercept of p(x) is -3, since p(x) is equal to 0 when x = -3.
Therefore, we can see that while the vertex of both functions is the same, their x-intercepts are different, which further confirms that the expressions defining m and p are not equivalent.

Find the solution of the square root of the quantity of x plus 3 plus 6 equals 9, and determine if it is an extraneous solution. x = 0; extraneous x = 0; not extraneous x = 6; extraneous x = 6; not extraneous
The equation square root of (x + 3) + 6 = 9 has two potential solutions, x = 0 and x = 6. However, upon analysis, it is determined that x = 0 is an extraneous solution while x = 6 is not extraneous.
To find the result of the given equation, we'll break it step by step and also determine if any results are extraneous.
The given equation is
√( x + 3) 6 = 9
Let's break it
Step 1 Subtract 6 from both sides of the equation
√( x +3) = 9- 6
√( x +3) = 3
Step 2 Square both sides of the equation to exclude the square root
( x + 3) = \(3^{2}\)
( x + 3) = 9
Step 3 Subtract 3 from both sides of the equation
x = 9- 3
x = 6
The result to the equation is x = 6.
Now, let's determine if this result is extraneous or not.
To check if the result is extraneous, we need to substitute it back into the original equation and see if it holds true.
Original equation √( x + 3) + 6 = 9
Substituting x = 6
√( 6 +3) + 6 = 9
√ 9 +6 = 9
3 +6 = 9
9 = 9
Since the equation holds true when x = 6, the result x = 6 is NOT an extraneous result.
thus, the correct statements are
x = 0; not extraneous
x = 6; not extraneous

In baseball, a player's batting average is calculated by dividing the number of hits by the number of times at bat. A major league baseball player had 50 hits and 150 at bats so far this season. How many consecutive hits does the player need to raise his overall batting average to 0. 375?
The player would need to get 10 consecutive hits to raise their overall batting average to 0.375.
Now, If a player has 50 hits in 150 at-bats, their current batting average is:
50 hits / 150 at-bats = 0.3333
For the number of consecutive hits needed to raise the player's batting average to 0.375, we can use the following formula:
(50 + x) / (150 + x) = 0.375
where x is the number of consecutive hits needed.
To solve for x, we can cross-multiply and simplify:
50 + x = 0.375 (150 + x)
50 + x = 56.25 + 0.375x
0.625x = 6.25
x = 10
Therefore, the player would need to get 10 consecutive hits to raise their overall batting average to 0.375.

When can parallelism make your algorithms run faster when could it make your algorithms run slower?
When an algorithm necessitates extensive sharing of instantaneous results, parallelism slows it down. Because there are multiple independent parallel processes and the right number of threads, parallelism will speed up an algorithm.
What algorithm is parallelizable?The ones with data dependencies are the most challenging. It will be exceedingly challenging, for instance, if you are dealing with a vector and the input for the computation at point n depends on the output at position n-1.
When this occurs, you must comprehend what the original algorithm is doing and take an alternative approach. For the aforementioned case, it might be a difficulty with digital signal processing including a feedback-containing digital filter. These are challenging to parallelize, but that is not the sole solution. Instead, you might use the filter and signal's fast Fourier transforms, multiply them, and then perform the inverse transform.

Select two choices that are true about the function f(x)=23x+14/x
Answer:
There is an asymptote at x = 0
There is an asymptote at y = 23
Step-by-step explanation:
Given the function:
(23x+14)/x
Vertical asymptote is gotten by equating the denominator to zero
Since the denominator is x, hence the vertical asymptote is at x = 0. This shows that there is an asymptote at x = 0
Also for the horizontal asymptote, we will take the ratio of the coefficient of the variables in the numerator and denominator
Coefficient of x at the numerator = 23
Coefficient of x at the denominator = 1
Ratio = 23/1 = 23
This means that there is an asymptote at y = 23

you buy 6 apples for $2.70 write and equation that can be used to express the relationship between the total price t and the number of apples a you buy.
1. t= 2.70a
2. t=0.45a
3. t=6a
t= 2.22a
Answer:
The correct answer is: 2. t=0.45a
Step-by-step explanation:
Let t be the price of apples
and a be the number of apples
The price and quantity are directly proportional
\(t \propto a\)
Removing the proportionality symbol introduces a proportionality constant in the equation
\(t = ka\)
So far we know that cost of 6 apples is $2.70
Putting in the equation
\(2.70 = k (6)\\k = \frac{2.70}{6}\\k = 0.45\)
Putting the values of k will give us:
\(t = 0.45a\)
Hence,
The correct answer is: 2. t=0.45a
Find the x-intercepts for the parabola defined by this equation: y=3x^2+3x-6
To find the x-intercepts of the parabola defined by the equation y=3x^2+3x-6, we need to set y=0 and solve for x. Using the quadratic formula, we can find the values of x that make y=0, giving us the x-intercepts of the parabola.
To find the x-intercepts of the parabola defined by the equation y=3x^2+3x-6, we need to set y=0 and solve for x. This is because the x-intercepts are the points where the graph intersects the x-axis, meaning y=0 at those points. Therefore, we can substitute y=0 into the equation and solve for x:
0 = 3x^2 + 3x - 6
We can simplify the equation by dividing both sides by 3:
0 = x^2 + x - 2
Now we can use the quadratic formula to solve for x:
x = (-b ± sqrt(b^2 - 4ac)) / 2a
Where a=1, b=1, and c=-2 are the coefficients of x^2, x, and the constant term, respectively.
Plugging in these values, we get:
x = (-1 ± sqrt(1^2 - 4(1)(-2))) / 2(1)
x = (-1 ± sqrt(9)) / 2
Which gives us two possible solutions:
x = (-1 + 3) / 2 = 1
x = (-1 - 3) / 2 = -2
Therefore, the x-intercepts of the parabola are at the points (1, 0) and (-2, 0).

A bal is hit from the ground. When the ball has traveled a horizontal distance of d meters, its height, h,
in meters, can be modeled by the function (d) = -1.8+d.
What is the horizontal distance from the point where the ball is hit to the point where the ball lands on the
ground?
The horizontal distance from the point where the ball is hit to the point where the ball lands on the ground is 1.8 meters.
To find the horizontal distance from the point where the ball is hit to the point where the ball lands on the ground, we need to find the value of d when the height h is 0 (since the ball is on the ground again).
The function provided is h(d) = -1.8 + d. Let's set h(d) to 0 and solve for d:
0 = -1.8 + d
Now, let's isolate d by adding 1.8 to both sides:
d = 1.8
So, the horizontal distance from the point where the ball is hit to the point where the ball lands on the ground is 1.8 meters.

Show that the function f(x) = x²(x + 1)² - on (-[infinity]0; +[infinity]0) (i) has an absolute maximum, and (ii) find that absolute maximum.
The function f(x) = x²(x + 1)² has an absolute maximum at x = -1/2, and the maximum value is 9/16.
How to Show that the function f(x) = x²(x + 1)² - on (-[infinity]0; +[infinity]0) has an absolute maximumTo show that the function f(x) = x²(x + 1)² has an absolute maximum on the interval (-∞, +∞), we need to analyze its behavior and find the critical points.
(i) Critical Points:
To find the critical points, we need to find where the derivative of f(x) is equal to zero or undefined.
Taking the derivative of f(x):
f'(x) = 2x(x + 1)² + x² * 2(x + 1)
Setting f'(x) equal to zero and solving for x:
2x(x + 1)² + 2x²(x + 1) = 0
2x(x + 1)((x + 1) + x) = 0
2x(x + 1)(2x + 1) = 0
This equation is satisfied when x = 0, x = -1, or x = -1/2. These are the critical points of f(x).
(ii) Absolute Maximum:
To find the absolute maximum, we evaluate the function at the critical points and the endpoints of the interval (-∞, +∞).
Let's evaluate f(x) at the critical points and the endpoints:
f(-∞) = (-∞)²((-∞) + 1)² = +∞ (as x approaches -∞, f(x) approaches +∞)
f(-1/2) = (-1/2)²((-1/2) + 1)² = 9/16
f(-1) = (-1)²((-1) + 1)² = 0
f(0) = 0²(0 + 1)² = 0
f(+∞) = (+∞)²((+∞) + 1)² = +∞ (as x approaches +∞, f(x) approaches +∞)
From the above evaluations, we can see that the function f(x) has an absolute maximum on the interval (-∞, +∞) at x = -1/2, and the value of the maximum is f(-1/2) = 9/16.
Therefore, the function f(x) = x²(x + 1)² has an absolute maximum at x = -1/2, and the maximum value is 9/16.

Answer:
\(\large \boxed{\sf \ \ 70\% \ \ }\)
Step-by-step explanation:
Hello,
We assume that the year is 52 weeks, and we note r the interest rate we are looking for. The rate is expressed in percent and is annually, meaning that the investment is, after the first week :
\(1000\cdot (1+\dfrac{r\%}{52})=1000\cdot (1+\dfrac{r}{5200})\)
For the second week
\(1000\cdot (1+\dfrac{r}{5200})^2\)
After 52 weeks
\(1000\cdot (1+\dfrac{r}{5200})^{52}\)
and we want to be equal to 2000 so we need to solve:
\(1000\cdot (1+\dfrac{r}{5200})^{52}=2000\\\\\text{*** divide by 1000 both sides ***}\\\\(1+\dfrac{r}{5200})^{52}=\dfrac{2000}{1000}=2\\\\\text{*** take the ln **}\\\\52\cdot ln(1+\dfrac{r}{5200})=ln(2)\\\\\text{*** divide by 52 ***}\\\\ln(1+\dfrac{r}{5200})=\dfrac{ln(2)}{52}\\\\\text{*** take the exp ***}\\\\\displaystyle 1+\dfrac{r}{5200}=exp(\dfrac{ln(2)}{52})=2^{(\dfrac{1}{52})}=\sqrt[52]{2}\\\\r = 5200\cdot (\sqrt[52]{2}-1)=69.77875...\)

What is the sum of the first five terms of a geometric series with a = 10 andr
= 1/5?
Answer:
12.496
Step-by-step explanation:
Here, to calculate the sum of the first five terms of the series, we use the formula for the sum of terms in a geometric series.
Mathematically, that would be;
Sn = a(1-r^n)/1-r
where Sn = ?
a = 10
r = 1/5 = 0.2
n = 5
Substituting these values into the equation above, we have;
Sn = 10(1-(0.2)^5)/1-0.2
