The required polynomial [tex]f(x) = x^4+5x^2-6[/tex] has the zeros -1, 1, [tex]i\sqrt6[/tex], and [tex]-i\sqrt6[/tex].
What is a polynomial ?
A polynomial is a mathematical expression that consists of variables and coefficients, combined by addition, subtraction, and multiplication, but not division by a variable.
To write a polynomial function of least degree with integral coefficients that has zeros of -1, 1, and [tex]i\sqrt{6[/tex], we need to include their conjugates as well. This is because complex roots always come in conjugate pairs.
The conjugate of [tex]i\sqrt{6[/tex] is [tex]-i\sqrt{6[/tex], so our polynomial function will have the following zeros: -1, 1, [tex]i\sqrt{6[/tex], and [tex]-i\sqrt{6[/tex].
To find the polynomial function, we can use the fact that the product of the factors of a polynomial is equal to the polynomial itself. So, we can start by multiplying out the factors:
[tex](x+1)(x-1)(x-i\sqrt6)(x+i\sqrt6)[/tex]
Expanding this out gives:
[tex](x^2-1)(x^2+6)[/tex]
Multiplying these two expressions gives:
[tex]x^4+5x^2-6[/tex]
So the polynomial function of least degree with integral coefficients that has zeros of -1, 1, and [tex]i\sqrt{6[/tex] is [tex]f(x) = x^4+5x^2-6[/tex]
To verify that this polynomial has the desired zeros, we can factor it using the difference of squares:
[tex]x^4+5x^2-6 = (x^2-1)(x^2+6) = (x-1)(x+1)(x^2+6)[/tex]
And the quadratic factor has no real roots, so it must be the factorization [tex](x-i\sqrt6)(x+i\sqrt6)[/tex].
Therefore, [tex]f(x) = x^4+5x^2-6[/tex] has the zeros -1, 1, [tex]i\sqrt6[/tex], and [tex]-i\sqrt6[/tex], as required.

Find the missing measurements in the triangle.
Angles should be to the nearest degree.
Side lengths should be rounded to the nearest tenth.
Answer: angle b= 63
Ac= 23.6
Ab=26.4
Step-by-step explanation:
angle b= 63
Ac= 23.6
Ab=26.4
Angle B is 63 degrees, the length of AC is approximately 22.23 units, and the length of AB is approximately 26.42 units.
What is right angle triangle?
A triangle in which one of its angles measures 90 degrees is called a right-angled triangle .
The side opposite the right angle is called the hypotenuse while the other two sides are called the legs or the adjacent and opposite sides.
According to given figure angle C is a right angle, we know that the sum of angles A and B must be 90 degrees.
So, angle B = 90 - angle A = 90 - 27 = 63 degrees.
To find the length of AC, we can use trigonometry. Since we know the length of the opposite side (BC) and the angle opposite the side we want to find (angle A), we can use the tangent function:
tan A = opposite / adjacent
tan 27 = BC / AC
AC = BC / tan 27
AC = 12 / tan 27
AC ≈ 22.23
Now,
[tex]AB^2 = AC^2 + BC^2 \\ AB^2 = 22.23^2 + 12^2 \\ AB^2 ≈ 697.57 \\ AB ≈ 26.42[/tex]
Therefore, Angle B is 63 degrees, the length of AC is approximately 22.23 units, and the length of AB is approximately 26.42 units.

x = sin t, y = 3 cos t
Answer:
16.39 square units.
Step-by-step explanation:
The parametric equations x = sin t and y = 3 cos t describe a curve in the xy-plane known as an ellipse.
To see this, we can use the Pythagorean identity for sine and cosine:
sin^2 t + cos^2 t = 1
Multiplying both sides by 9, we get:
9 sin^2 t + 9 cos^2 t = 9
Substituting x = sin t and y = 3 cos t, we get:
9 x^2 + y^2/3 = 9
This is the equation of an ellipse centered at the origin with semi-axes a = 3 and b = sqrt(3), where a is the length of the horizontal semi-axis and b is the length of the vertical semi-axis.
The area of an ellipse is given by the formula:
Area = pi * a * b
Substituting the values of a and b, we get:
Area = pi * 3 * sqrt(3) ≈ 16.39
Therefore, the area of the ellipse described by the parametric equations x = sin t and y = 3 cos t is approximately 16.39 square units.

θ=1 rad when S=r. If θ=2 rad then what is the condition? :::::::(S means arc length)
If θ=2 rad then the condition when θ=2 rad is that the arc length S is equal to twice the radius r.
In this problem, we are given that when the arc length is equal to the radius (S=r), the angle is 1 radian (θ = 1 rad). Now, we are asked to find the condition when the angle is 2 radians (θ = 2 rad).
If Θ=1 rad when S=r, it means that when the angle subtended by an arc of length r is 1 radian, then the radius of the circle is also r.
Now, if θ=2 rad, we can use the same proportionality to find the arc length S that corresponds to this angle. Since the angle has doubled, we can expect the arc length to double as well. Therefore, we have:
θ/Θ = S/r
2/1 = S/r
S = 2r
Thus, the condition when θ=2 rad is that the arc length S is equal to twice the radius r.

the number y is 8 less than 2 times another number x, their sum is 7
The two numbers given by the algebraic expressions are x = 5 and y = 2.
What is system of equation?A system of equations is a set of two or more equations that are to be solved simultaneously. In other words, a system of equations represents multiple relationships between variables that need to be solved for at the same time. A system of equations can be solved using various methods, such as substitution or elimination. The goal of solving a system of equations is to find the values of the variables that satisfy all of the equations in the system. One common method for solving systems of linear equations is called Gaussian elimination, which involves manipulating the equations in the system to eliminate one variable at a time until a solution is found.
Let us suppose the numbers as x and y.
From the given statement the mathematical expression can be set as:
y = 2x - 8
x + y = 7
Now. substituting the value of y in equation we have:
x + (2x - 8) = 7
3x - 8 = 7
3x = 15
x = 5
Now, for x = 5 the value of y is:
y = 2(5) - 8

Which of the points below correctly plots the point (4,4π/3)?
Answer: the correct answer is B
Step-by-step explanation:
Remember that the coordinates (4,4π3) tell us the radius r=4 and the angle θ=4π3. So the point should be on the circle labeled 4 and form an angle of 4π3 with the positive x-axis. Point B is the correct point.
If you repeat this experiment 360 times, how many repetitions do you predict will result in the same letter being spun for both spins?
Answer:
90
Step-by-step explanation:
You want to know the number of times in 360 trials that the same letter will appear twice in a row using a fair 4-letter spinner.
ProbabilityThe table shows 4 outcomes of the 16 possible that have the same letter repeated. That's a probability of a repeated letter of 4/16 = 1/4.
Expected numberThe expected number of repeated letters in 360 trials is the number of trials times the probability of a repeat:
expected repeats = 360 × 1/4 = 90
You predict there will be 90 repetitions in 360 trials.

According to a study done by De Anza students, the height for Asian adult males is normally distributed with an average
of 66 inches and a standard deviation of 2.5 inches. Suppose one Asian adult male is randomly chosen. Let X = height of
the individual
The middle 40% of heights fall between what two values? Sketch the graph, and write the probability statement
The probability statement is written below:
P(62.8 ≤ X ≤ 69.2) = 0.4What is the probability statement?The middle 40% of heights fall between the 10th and 90th percentiles of the standard normal distribution.
The z-scores of the 10th and 90th percentiles are -1.28 and 1.28 respectively.
The heights in the given normal distribution are found using the formula:
X = μ + zσwhere
X is the height,μ is the mean height = 66 inchesσ is the standard deviation = 2.5 inchesz is the z-score.The height of the 10th percentile is:
X = 66 + (-1.28)(2.5)
X = 62.8 inches
The height of the 90th percentile is:
X = 66 + (1.28)(2.5)
X = 69.2 inches
Therefore, the middle 40% of heights fall between 62.8 inches and 69.2 inches and the probability statement will be P(62.8 ≤ X ≤ 69.2) = 0.4

Ahmad received a $1100 bonus. He decided to invest it in a 2-year certificate of deposit (CD) with an annual interest rate of 1.14% compounded daily.
Answer the questions below. Do not round any intermediate computations, and round your final answers to the nearest cent. If necessary, refer to the
list of financial formulas. Assume there are 365 days in each year.
(a) Assuming no withdrawals are made, how much money is in Ahmad's
account after 2 years?
(b) How much interest is earned on Ahmad's investment after 2 years?
The interest that have been earned after two years is $25.
What is the compound interest?A type of interest known as compound interest is computed using both the original sum and any accrued interest from earlier periods. The interest that is earned on interest is, in other terms, interest.
We know that by the compound interest formula;
A = P(1 + r/n)^nt
A = amount
P = principal
r = rate
n = Number of times compounded
t = time
Thus;
A = 1100(1 + 0.0114/365)^365* 2
A = $ 1125
Thus the interest after two years is;
$ 1125 - $1100
= $25
