The remainders obtained when px³ + qx² + 4x − 2 is divided by x-1 and x + 2 are
equal. Show that 3p - q = -4. If also the remainder is -18 when the polynomial is
divided by x-2, find the value of p and of q.
Our first equation yields p = 0. We obtain q = 3p = 0 by substituting this in the second equation. Hence, p = q = 0. As a result, the values of p and q are both zero.
what is polynomial ?A polynomial is a mathematical equation composed of variables and coefficients that is solved using mathematical operations like combination, deletion, multiplication, and quel integer exponents.
given
The result of dividing the same polynomial by x + 2 is
(p[tex]x^{2}[/tex] + (2p-q)x + (5q-2))(x+2) + (q[tex]x^{3}[/tex] + q[tex]x^{2}[/tex]+ 4[tex]x^{2}[/tex]) (12p-9q-2)
p+2q-2 = 12p-9q-2
When we simplify this equation, we obtain:
11p + 2q = 0
=> 3p - q = -4 (by adding 22p to both sides and multiplying both sides by 2)
Now, we also understand that the polynomial, when divided by x – 2, leaves a remainder of -18. Synthetic division or polynomial long division yields the following results:
= (p (x-2)³ + (7p-2q)(x-2) (x-2)² + (18q-8p)(x-2)) - 18
When we compare coefficients, we find:
p = 7p - 2q = 18q - 8p = 0
Our first equation yields p = 0. We obtain q = 3p = 0 by substituting this in the second equation. Hence, p = q = 0. As a result, the values of p and q are both zero.

in a randomized controlled trial, sometimes patients agree to receive an intervention but later decide to stop taking the medication. moreover, some patients who were assigned to placebo decide to stop taking the placebo pill and buy the drug on their own (even when they do not know that they are taking a placebo pill). when this happens, researchers typically do the analysis according to the original assignment of the treatment regardless of the actual treatment received. what is the name of this procedure to analyze the data?
The procedure used to analyze the given data is intention-to-treat analysis.
The procedure to analyze data according to the original assignment of the treatment regardless of the actual treatment received is called the intention-to-treat (ITT) analysis. It is considered the gold standard in clinical trial analysis because it preserves the randomization and avoids bias that may arise from differential dropouts or non-compliance. By analyzing all patients according to their randomized group, the ITT analysis provides an unbiased estimate of the treatment effect and better reflects the real-world effectiveness of the intervention.
The intention-to-treat (ITT) analysis is different from other types of analyses because it includes all patients according to their original randomized group, regardless of whether they received the assigned treatment or not. This is in contrast to per-protocol analysis, where only patients who completed the study without any major protocol deviations are included, or as-treated analysis, where patients are analyzed according to the actual treatment received.

Answer: The probability that Travis will choose a mystery book is 1/3.
Step-by-step explanation: To find the probability that Travis will choose a mystery book, we need to determine the ratio of the number of mystery books to the total number of books on Travis's shelf.
Travis has 6 mystery books, and the total number of books on his shelf is 6 + 5 + 4 + 3 = 18.
Therefore, the probability (in fraction form) that Travis will choose a mystery book is 6/18.
To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 6.
6 ÷ 6 = 1
18 ÷ 6 = 3
So, the simplified fraction is 1/3.

Nicole is 1.55 meters tall. At 2 p.m., she measures the length of a tree's shadow to be 30.05 meters. She stands 25.6 meters away from the tree, so that the tip of her shadow meets the tip of the tree's shadow. Find the height of the tree to the nearest hundredth of a meter.
Answer:
approximately 1.81 meters.
Step-by-step explanation:
Let's call the height of the tree "h". We can set up a proportion based on the similar triangles formed by Nicole, her shadow, the tree, and the tree's shadow:
(height of Nicole) / (length of Nicole's shadow) = (height of tree) / (length of tree's shadow)
Substituting the given values, we get:
1.55 / 25.6 = h / 30.05
Simplifying and solving for h, we get:
h = (1.55 / 25.6) * 30.05
= 1.81181640625
Rounding to the nearest hundredth, we get:
h ≈ 1.81 meters
the height of the tree is approximately 1.81 meters.

The vertices of a rhombus are located at the coordinates (1, 3), (4, 7), (9, 7),
and (6, 3)
Find the length of the horizontal sides of the rhombus and its perimeter.
Answer: To find the length of the horizontal sides of the rhombus, we need to find the distance between points (1, 3) and (9, 7), which is the same as the distance between points (4, 7) and (6, 3).
Using the distance formula:
d = √[(x₂ - x₁)² + (y₂ - y₁)²]
d = √[(9 - 1)² + (7 - 3)²]
d = √[64 + 16]
d = √80
d ≈ 8.94
So the length of the horizontal sides of the rhombus is approximately 8.94 units.
To find the perimeter of the rhombus, we need to find the distance between all four vertices and add them up.
Using the distance formula:
d₁ = √[(4 - 1)² + (7 - 3)²] = √25 = 5
d₂ = √[(9 - 4)² + (7 - 7)²] = √25 = 5
d₃ = √[(6 - 9)² + (3 - 7)²] = √16 + 16 = √32 ≈ 5.66
d₄ = √[(1 - 6)² + (3 - 7)²] = √25 + 16 = √41 ≈ 6.40
Perimeter = d₁ + d₂ + d₃ + d₄ = 5 + 5 + 5.66 + 6.40 ≈ 22.06
So the perimeter of the rhombus is approximately 22.06 units.

Determine whether the graph of the equation is symmetric with respect to the
The graph of the equation y = x² + 5 is symmetric with respect to the y-axis, the correct option is (b).
To determine the symmetry of the graph, we can substitute (-x) for x in the equation and simplify:
y = (-x)² + 5
y = x² + 5
Since the equation is unchanged when x is replaced by (-x), the graph is symmetric with respect to the y-axis.
We can also see that the graph is not symmetric with respect to the x-axis or the origin. To check for symmetry with respect to the x-axis, we can substitute (-y) for y in the equation:
(-y) = x² + 5
y = -(x² + 5)
The equation is not the same as the original equation, so the graph is not symmetric with respect to the x-axis. Similarly, to check for symmetry with respect to the origin, we can substitute (-x) and (-y) for x and y in the equation:
(-y) = (-x)² + 5
y = x² + 5

write the opposite of -4 1/2 and explain how it's related to -4 1/2. Use a number line as a reference in your explanation. Use the number line to think about the location of the number 2 and the number n, where n is greater than 3. write an inequality comparing the opposite of 2 and the opposite of n. explain how the number line shows that your inequality is correct
We can use the number line to see that 2 and any number greater than 3 are to the right of -4 1/2. By finding the Opposites of 2 and n and comparing them, we can write an inequality that is correct based on the number line.
The opposite of -4 1/2 is 4 1/2. This is because the opposite of a number is the number that is the same distance from 0 on the number line, but in the opposite direction. On a number line, -4 1/2 is to the left of 0, so its opposite, 4 1/2, is to the right of 0.
Looking at the number line, we can see that the number 2 is to the right of -4 1/2, but to the left of 4 1/2. Any number greater than 3, represented by n, is also to the right of -4 1/2.
The opposite of 2 is -2 and the opposite of n is -n. So, the inequality we can write is:
-n < -2
This is because -2 is to the left of -n on the number line. We can see that this inequality is correct on the number line because -2 is closer to 0 than -n, which means that -n is less than -2.
In summary, the opposite of -4 1/2 is 4 1/2, and it is related to -4 1/2 because they are the same distance from 0 on the number line, but in opposite directions. We can use the number line to see that 2 and any number greater than 3 are to the right of -4 1/2. By finding the opposites of 2 and n and comparing them, we can write an inequality that is correct based on the number line.
