In order to find if each binomial is a factor of the given polynomial function, we can use the zero remainder theorem.
This theorem states that if a value x = k is a zero of the function f(x) (that is, f(k) = 0), so the binomial (x - k) is a factor of the function f(x).
Therefore, let's check the values 1, 3, -3, 4 and -4:
\(\begin{gathered} f(1)=1+4-9-36=-40 \\ f(3)=27+36-27-36=0 \\ f(-3)=-27+36+27-36=0 \\ f(4)=64+64-36-36=64 \\ f(-4)=-64+64+36-36=0 \end{gathered}\)Therefore the answer is:
(x - 1): No
(x - 3): Yes
(x + 3): Yes
(x - 4): No
(x + 4): Yes
Calculate the mean of the following data x 5 ,10 ,15, 20, 25, f 3, 2 ,6, 4 ,8.
The overall mean would be the average of the means of the two sets, which is 9.8.
To calculate the mean of a set of data, you need to sum up all the values and divide by the total number of values. In this case, we have two sets of data: the first set is {5, 10, 15, 20, 25}, and the second set is {3, 2, 6, 4, 8}.
For the first set, the sum of the values is 5 + 10 + 15 + 20 + 25 = 75. There are 5 values in this set. So, the mean of the first set is 75 divided by 5, which equals 15.
For the second set, the sum of the values is 3 + 2 + 6 + 4 + 8 = 23. There are 5 values in this set as well. Therefore, the mean of the second set is 23 divided by 5, which equals 4.6.
To find the overall mean, we need to calculate the weighted average of the means of the two sets. Since we don't have information about the weights assigned to each set, we cannot provide an exact overall mean.
However, if both sets have equal importance, we can assume equal weights. In that case, the overall mean would be the average of the means of the two sets, which is (15 + 4.6) / 2 = 9.8.
Please note that without information about the weights assigned to each set, this assumption of equal weights is arbitrary, and the overall mean could differ if the weights are different.

The measure of arc angle QTP is 204 degrees.
How to find arc angle?When a tangent and a secant intersect outside a circle then the measure of the angle formed is one-half the positive difference of the measures of the intercepted arcs.
Therefore, let's find the measure of arc angle QTP as follows:
90 = 0.5(x - 68)
90 = 0.5x - 34
0.5x = 124
x = 124 / 0.5
x = 248 degrees
Where
x = arc angle TSQ
Therefore,
arc QP = 44 degrees

arc QTP = 248 - 44

Given that a+b = 10 and a square - b square = 40 find the value of a-b
Answer:
the value of a - b is 4.
Step-by-step explanation:
We have been given the following two equations:
a + b = 10 ------------(1)
a² - b² = 40 -------(2)
We can factor the left-hand side of equation (2) using the difference of squares identity:
(a + b)(a - b) = 40
Substituting equation (1) into this equation, we get:
10(a - b) = 40
Dividing both sides by 10, we get:
a - b = 4
Therefore, the value of a - b is 4.
Step-by-step explanation:
if I understand this correctly :
a + b = 10
a² - b² = 40
(a² - b²) = (a + b)(a - b) = 40
10(a - b) = 40
(a - b) = 4

if the number of data observations is even, the median is generally considered to be the average of the first and last values
False, that is if the number of data observations is even, the median is generally considered to be the average of middle values not the first and last values.
The median is a simple measure of central tendency. To find the median, we arrange the observations in order from smallest to largest value. If there is an odd number of observations, the median is the middle value. If there is an even number of observations, the median is the average of the two middle values.
At least half of the observations are equal to or smaller than the median, and at least half of the measurements are equal to or greater than the median. The median divides the bottom half of observations from the upper half.
Even Number of Observations :
Suppose we have the monthly wages of 4 employees of a company. How would you find the median wage?
wages are 120,240,500,400
we have arranged their wages above from lowest to highest. This ranking will help us to determine the median. Using the method introduced earlier, the median is computed by taking the simple average of the (n/2)ᵗʰ = (4/2)ᵗʰ = 2ⁿᵈ and
(n/2 + 1)ᵗʰ = (2+1)ᵗʰ = 3ʳᵈ observations.
Therefore, the median is 240+500/2

Applying the product rule gives
\(\displaystyle \frac{d}{dx}\int_1^{x^2}\frac{2t}{1+t^2}\,dt \times \int_1^{\ln(x)}\frac{dt}{(1+t)^2} + \int_1^{x^2}\frac{2t}{1+t^2}\,dt \times \frac{d}{dx}\int_1^{\ln(x)}\frac{dt}{(1+t)^2}\)
Use the fundamental theorem of calculus to compute the remaining derivatives.

The remaining integrals are
\(\displaystyle \int_1^{\ln(x)}\frac{dt}{(1+t)^2} = -\frac1{1+t}\bigg|_1^{\ln(x)} = \frac12-\frac1{1+\ln(x)}\)
\(\displaystyle \int_1^{x^2}\frac{2t}{1+t^2}\,dt=\int_1^{x^2}\frac{d(1+t^2)}{1+t^2}=\ln|1+t^2|\bigg|_1^{x^2}=\ln(1+x^4)-\ln(2) = \ln\left(\frac{1+x^4}2\right)\)
and so the overall derivative is
\(\displaystyle \frac{4x^3}{1+x^4} \left(\frac12-\frac1{1+\ln(x)}\right) + \frac{1}{x(1+\ln(x))^2} \ln\left(\frac{1+x^4}2\right)\)

Find the equation of the line in slope-intercept form through the point (-6,4) and Perpendicular to the line y = -1/2x + 8
Answer:
y = 2x + 16
Step-by-step explanation:
Remember: The slope of perpendicular lines are negative reciprocals of each other.
1. Find the slope using the given equation.
y= -1/2x + 8 Using the slope- intercept form y = mx + b, the slope is -1/2 because it is the coefficient of the x-term .
The new line is perpendicular to the given line and their slopes are negative reciprocals of each other. You will use a slope = 2
2. Substitute into the slope intercept form y = mx +b , the value of the slope, "m" and the given point (-6, 4) and solve for "b"
y = mx + b
4 = 2(-6) + b
4 = -12 + b
