question content area top part 1 find the average rate of change of the function over the given intervals. f(x)=11x3 11; a) [6,8], b) [−1,1]
Answers
the average rate of change = (f(1) - f(-1))/(1-(-1)). Substituting in the values of f(-1) and f(1), we get (143 - (-143))/2
a) Average rate of change of the function over [6,8] = (f(8) - f(6))/(8-6) = (11(83) - 11(63))/2 = 882/2 = 441
b) Average rate of change of the function over [-1,1] = (f(1) - f(−1))/(1-(−1)) = (11(13) - 11(-13))/2 = 244/2 = 122
a) To find the average rate of change of the function f(x)=11x3 over the interval [6,8], first calculate the value of the function at x=6 and x=8. This gives us f(6) = 11(63) = 729 and f(8) = 11(83) = 1728. Then, the average rate of change = (f(8) - f(6))/(8-6). Substituting in the values of f(6) and f(8), we get (1728 - 729)/2 = 882/2 = 441.
b) To find the average rate of change of the function f(x)=11x3 over the interval [-1,1], first calculate the value of the function at x=-1 and x=1. This gives us f(-1) = 11(-13) = -143 and f(1) = 11(13) = 143. Then, the average rate of change = (f(1) - f(-1))/(1-(-1)). Substituting in the values of f(-1) and f(1), we get (143 - (-143))/2

Hey if anybody could please give me a hand and explain this question to me and help me out that would be great

Answer:
Step-by-step explanation:
We can use similar triangles to solve this. The bigger triangle is made up of the water tower as the height and the long horizontal line as its base, and the smaller triangle fitted inside the larger is made up of the tripod of the camera as the height and the distance Brian lies on the ground beyond it as the base for that triangle. We have to add this distance to the distance of the larger triangle's base. Setting it up as a proportion:
[tex]\frac{watertower}{base} =\frac{camera}{base}[/tex]
but since everything is in different measurements, we have to sort that out first. Let's change everything to feet.
The water tower's distance is 100 yards + 2 feet 9 inches:
[tex]100yds*\frac{3ft}{1yd}=300'[/tex] and now we add in 2 feet 9 inches which is 2.75 feet to get a total of 302.75 feet from the base of the water tower to the point of the triangle. Since we have already converted Brian's distance to feet we're ready to set up the proportion:
[tex]\frac{x}{302.75} =\frac{5}{2.75}[/tex] and we cross multiply.
2.75x = 1513.75 and divide to get
x = 550.45 feet tall.

If a polynomial equation P(x)= 0 has 3+4i as a solution, what other solution must it have?
Answers
Answer: 3 - 4i
Step-by-step explanation:
For the given polynomial p(x) , if 3 +4i is a root then, 3 - 4i is also the root of p(x).
Consider the given polynomial equation p(x) = 0 It is given that the polynomial P(x) has one root 3 + 4i .
According to complex conjugate theorem, if V is a polynomial and x + iy is a root of given polynomial then its conjugate x - iy is also the root of the polynomial.
Thus, for the given polynomial p(x) if 3 +4i is a root then, 3 - 4i is also the root of p(x).
If a polynomial equation P(x) = 0 has (3 + 4i) as a solution, the other solution it must have (3 - 4i).
What is a polynomial?
Polynomial is formed composed of the phrases Nominal, which means "terms," and Poly, which means "many." An expression that consists of variables, constants, and exponents that is combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial.
Conjugate complex numbers are those that only differ in the imaginary part's sign.
a + bi and a - bi, where a and b are real numbers, are generally conjugate, as are, for instance, 2 + 3i and 2 - 3i, -5 - 7i and -5 + 7i, and so on.
Due to the fact that their output is always a genuine number.
The general case is -
= (a + bi)(a - bi)
= a² - abi + abi - (b²)(i²)
= a² + b²
The real example is -
= (2 + 3i)(2 - 3i)
= 2² + 3²
= 4 + 9
= 13
Complex roots for a polynomial equation P(x) = 0 with real coefficients are always represented as conjugate pairs.
So, the following equation must contain (3 - 4i) as a second root if the coefficients are real.
Therefore, P(x) has second root (3 - 4i).

The magnitude of f3 is 6.403N and the coordinate direction angle is 247.9°
We can calculate the magnitude and coordinate direction angle of f3 using the vector triangle method.
We assume that the coordinate direction angle of f1 is 0° and the coordinate direction angle of f2 is 90°.
Using the law of cosines, we can determine the magnitude of f3, which is 6.403N:
f3^2 = f1^2 + f2^2 -2f1f2cos180°
f3^2 = 5^2 + 8^2 -2(5)(8)cos180°
f3^2 = 25 + 64 -80
f3^2 = 49
f3 = 6.403N
We can then use the law of sines to determine the coordinate direction angle of f3, which is 247.9°:
sinθ3 = f2sin180°/f3
sinθ3 = (8)(180°)/6.403
sinθ3 = 147.6°

consider the formula k = 1/(1-s). what happens to the variable k when s grows in value?
Answers
When s grows in value, the value of variable k decreases.
Consider the formula k = 1/(1 - s)
We know that when the value of one quantity 'm' increases with respect to decrease in the value of other 'n' or vice-versa, then we say that the two quantities 'm' and 'n' are inversely proportional to each other.
We write this as,
m∝ 1/n
m = p/n
where p is the constant of proportionality
From the formula k = 1/(1 - s) we can observe that the quantities k and s are inversely proportional to each other.
this means, when the value of variable s increases, there is decrease in value of variable k.

Suppose we observe the following rates: 1R1 = .08, 1R2 = .12, and E(2r1) = 14. If the liquidity premium theory of the term structure of interest rates holds, what is the liquidity premium for year 2? Hint: Ry[(1+R)+E(277)+4)...Q+E(x7)+Lx)} N-1 O 6.15% O 2.15% O 14.00% O 8.45% O 12.45%
Answers
If the liquidity premium theory of the term structure of interest rates holds, 0.498% is the liquidity premium for year 2.
What is liquid premium theory?Any additional compensation that is necessary to attract investment in assets that cannot be quickly and effectively converted into cash at fair market value is known as a liquidity premium. Because it is more difficult to sell than a short-term bond, a long-term bond, for instance, will have a higher interest rate. According to the principle of the liquidity premium, bond investors favour short-dated assets that are highly liquid and have a short sales cycle over those that are longer-dated. According to another tenet of the theory, fluctuations in interest rates provide investors with compensation for greater pricing and default risks.
Given that,
1 + 1R₂= {(1 + 1R₁)(1 + E(2r₁) + L₂)}1/2
or, 1.12 = (1.8)(1.14 + L₂)1/2
or, (1.12)2/1.18 = 1.14 + L₂
or, 1.898 = 1.14 + L₂
or, L₂ = 0.498%

three computer viruses arrived as an email attachment. virus a damages the system with probability 0.4. independently of it, virus b damages the system with probability 0.5. independently of a and b, virus c damages the system with probability 0.2. what is the probability that the system gets damaged? 0.96 0.24 0.76 0.04
Answers
The probability that the system gets damaged is P(AUBUC)=0.76
If the probability of occurrence of an event A is not affected by the occurrence of another event B, then A and B are said to be independent events.
The two events are said to be independent events if the outcome of one event does not affect the outcome of another.
The formula can be defined as:
P(A and B) = P(A)×P(B)P(A and B) = P(A)×P(B)
For independent events U and V we have P(U∩V)=P(U)P(V)
if the viruses are truly independent then the probability that the system gets damaged=
P(AUBUC)=P(A)+P(B)+P(C)-P(AnB)-P(anc)-P(bnc)+P(AnBnC).
0.4+0.5+0.2-0.4*0.5-0.4*0.2-0.5*0.2+0.4*0.5*0.2=1.1-0.2-0.08-0.1+0.04

what should be t-value to indicate that curve is not over flattening in smoothening of time series data
Answers
When smoothing time series data, it's important to ensure that the curve is not over-flattened, as this can lead to important information being lost.
What should be t-value to indicate that curve is not over flattening?To avoid over-flattening, one approach is to use a threshold value, or "t-value", to determine the maximum amount of smoothing that can be applied.Here are some steps to consider when choosing a t-value:Plot the original time series data and the smoothed curve to visualize the smoothing effect.Compare the slope of the smoothed curve to the slope of the original data.Choose a t-value that preserves the important features of the original data, such as trends, seasonality, and outliers.Ensure that the smoothed curve still accurately represents the underlying pattern in the data, while reducing noise and variability.Re-evaluate the t-value if necessary, based on the visual comparison of the original data and the smoothed curve.The t-value should be chosen such that the smoothed curve captures the underlying pattern in the data, while retaining important features such as trends and seasonality. If the t-value is set too high, the curve may become over-flattened and important information may be lost. On the other hand, if the t-value is set too low, the curve may not effectively reduce noise and variability in the data.To learn more about T-value refer:

Determine if the triangles are similar by side-angle-side similarity
Answers
Answer:
Step-by-step explanation:
note that all adjacent triangles will share an angle.
for 13 and 14 this is the case.
for 13 and 14 the adjacent sides are also multiples of each other proportionately. find this by dividing one side by the other for both triangles. if equal they are proportionately larger.
13 and 14 are both similar
for 15 and 16 the same logic can be applied to the side lengths. however, we are not given any information on the angles and cannot determine the angles mathematically.
for 17 and 18 the same logic can be applied again for the sides and given that the angles are confined within each other, the angles are the same.
for 17 and 18 you must add the side lengths for each side together and divide to determine the ratio and compare that to the ratio of the initial triangle

the mean composite score for seniors who took the sat in 2018 was 1068. if the standard deviation for this same year was 180, what is the raw score for a person with a z score of –0.42?
Answers
A person with a Z-score of -0.42 would have a raw score of 992.4 on the SAT taken in 2018.
The standard deviation is a measure of how much the data varies from the mean. A Z-score is a standardized value that represents the number of standard deviations a raw score is from the mean.
To find the raw score given a Z-score, we can use the following formula:
raw score = mean + Z-score * standard deviation
For the mean composite score of 1068 and a standard deviation of 180, we can plug in the values for the Z-score of -0.42:
raw score = 1068 + (-0.42) * 180
raw score = 1068 - 75.6
raw score = 992.4
Note: The Z-score of -0.42 indicates that the raw score is 0.42 standard deviations below the mean.
