find the average value of the following function on the given interval. draw a graph of the function and indicate the average value. f(x); [0,1] for any integer n greater than 1
The average value is the intersection point between the function and the line, which is at (0,1+C).
The average value of a function on an interval can be calculated using the following formula: Average Value = (1/b-a)∫a b f(x)dx. In this case, the function is f(x) and the interval is [0,1]. To calculate the average value, we must first calculate the integral of the function on the given interval. The integral of f(x) is nx^n-1 + C, where C is a constant. Using the fundamental theorem of calculus, we can evaluate the integral from 0 to 1 to be 1 + C.
The average value of the function on the given interval is then (1/1-0)∫0 1 (1+C)dx, which simplifies to 1+C. Therefore, the average value of the function on the given interval is 1 + C.
Graphically, the average value of the function on the given interval can be seen by plotting the graph of the function, which is a parabola with a vertex at (0,0), and a line at y=1+C. The average value is the intersection point between the function and the line, which is at (0,1+C).

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?
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.

determine the magnitude and coordinate direction angles of f3 so that the resultant of the three is 0
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°

a sample of 137cs (half-life = 30.1 years) decays at a rate of 10^10 decays per second. how long (in years) will it take the decay rate to decrease to 10^7 decays per second?
It will take 19.44 years for the decay rate of 137Cs to decrease to 10^7 decays per second.
The decay rate of 137Cs is given by the formula:
A = A0 * e^(-λt)
Where A is the decay rate, A0 is the initial decay rate (10^10 decays per second), λ is the decay constant (ln(2)/30.1 years) and t is the time in years.
To calculate the time, t, required for the decay rate to decrease to 10^7 decays per second, we solve for t and substitute the given values into the equation:
[tex]t = (ln(A0/A))/λ\\t = (ln(10^10/10^7))/(ln(2)/30.1)\\t = 19.44 years[/tex]

a scale of 1:900,000 is ________ a scale of 1:24,000
A scale of 1:900,000 is 36 times smaller than a scale of 1:24,000.
This can be expressed mathematically as a ratio: 1:900,000 = 1:24,000 / 36. To calculate the scale factor between two maps, divide the denominator of the larger scale by the denominator of the smaller scale. In this example, the scale factor is 36.
A scale of 1:900,000 means that one unit on the map represents 900,000 units of the same type in the real world. For example, one centimeter on the map could represent 900,000 centimeters in real life, or 9 kilometers. A scale of 1:24,000 would mean that one unit on the map represents 24,000 units of the same type in the real world. For example, one centimeter on the map could represent 24,000 centimeters in real life, or 0.24 kilometers.
The scale factor is the number that is used to compare the size of one map to another. In this example, a map with a scale of 1:900,000 is 36 times smaller than a map with a scale of 1:24,000. This means that the features on the 1:900,000 map are 36 times smaller than the same features on the 1:24,000 map. Therefore, the 1:900,000 map is not as detailed as the 1:24,000 map.

Team A needs to sell 255 bags of popcorn to reach their goal of $100.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Team A will sell the bags of popcorn for $0.50 each.
Team B will sell the cotton candy for $0.75 per stick.
Let the number of bags of popcorn sold by Team A be "x".
So, the total cost for the popcorn machine rental and supplies is
= $15 + 0.05x.
To reach their goal of $100
$100 = 0.5x - ($15 + 0.05x)
$100 = 0.5x - $15 - 0.05x
$115 = 0.45x
x = $115 / 0.45
x = 255 bags of popcorn
Thus, Team A needs to sell 255 bags of popcorn.

If a polynomial equation P(x)= 0 has 3+4i as a solution, what other solution must it have?
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 dots, which represent the sample proportions obtained by the students,
A) will all be at the same number.
B) will be wildly unpredictable.
C) will be clustered around 0 and 1.
D) will be centered around p, the true population proportion.
The correct option is "will be centered around p, the true population proportion."
What are random sample?Random sampling is a part of the sampling technique in which each sample has an equal probability of being chosen.
Given that, the students select their random samples and plot the results on a dot plot, the dots, represent the sample proportions obtained by the students,
Since, the dots are representing the sample proportions, we know,
The population proportion is equal to the mean of the sampling distribution of the sample proportion.
Hence, the correct option is "will be centered around p, the true population proportion."

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%
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%

find the volume of the solid obtained by rotating the region bounded by the curves y=1−x2 and y=0 about the x-axis.
The volume of the region will be 4/3 cubic unit with the help of integration.
What is integration?
Integration is the calculation of an integral. Integrals in maths are used to find many useful quantities such as areas, volumes, displacement, etc. When we speak about integrals, it is related to usually definite integrals. The indefinite integrals are used for antiderivatives. Integration is one of the two major calculus topics in Mathematics, apart from differentiation(which measure the rate of change of any function with respect to its variables).
Definite Integral
An integral that contains the upper and lower limits then it is a definite integral. On a real line, x is restricted to lie. Riemann Integral is the other name of the Definite Integral.
A definite Integral is represented as:
∫f(x)dx from a to b.
Indefinite Integral
Indefinite integrals are defined without upper and lower limits. It is represented as:
∫f(x)dx = F(x) + C
Where C is any constant and the function f(x) is called the integrand.
Now,
For volume
Integrate y=1-x^2 for x=-1 to 1.
volume=1-x^2.dx
V=x-x^3/3
=1-1/3+1-1/3
=2-2/3
Hence,
Volume=4/3 cubic unit

The height of the tree is obtained as 27.7 m
What is the height of the light pole?We have to note that in the solution of the problem that the tangent of the angle is going to come in to play. The tangent if one of the trigonometric ratios and the other ratios are the cos and the sine.
We know that the tangent of the angle is;
tan 36 = opposite/adjacent
Opposite of the angle = x + 5
(Where x is the height of the tree)
Adjacent of the angle = 45 m
We would then have that;
tan 36 = x + 5/45
45 tan 36 = x + 5
x = (45 tan 36) - 5
x = 27.7 m
