Answer:
m CAD is 41°
Step-by-step explanation:
The angles in a rectangle are 90 degrees each as the sides are perpendicular. A such, given that mzBAC = (4x + 5)º and m CAD = (5x - 14)°, then
4x + 5 + 5x - 14 = 90
Rearrange the equation
4x + 5x + 5 - 14 = 90
9x - 9 = 90
Collect like terms
9x = 90 + 9
9x = 99
Divide both sides by 9
x = 99/9
= 11
Recall that m CAD = (5x - 14)°
Substitute the value of x into the expression
Hence
m CAD = (5*11 - 14)°
= (55 - 14)°
= 41°

1) Write a polynomial equation for a function with a graph that bounces off the x-axis at (-1,0),
crosses it at (4,0), and goes through the point (-2, -18).
Answer:
f(x) = 3x³ -6x² -21x -12
Step-by-step explanation:
You want a polynomial function that touches the x-axis at x = -1, crosses it at x = 4, and goes through the point (-2, -18).
Factored formEach zero (p) of a polynomial corresponds to a linear factor (x -p). If the zero has even multiplicity, the function will not change sign there, but will touch the x-axis and "bounce".
The requirements indicate a factor (x +1) with even multiplicity, and a factor (x -4). The least-degree such polynomial will have the factored form ...
f(x) = a(x +1)²(x -4)
ScalingThe value of this polynomial at x = -2 is ...
f(-2) = a(-2 +1)²(-2 -4) = -6a
We want this to be -18, so ...
-6a = -18 ⇒ a = 3
Then the factored polynomial is ...
f(x) = 3(x +1)²(x -4)
When we multiply this out, we get ...
f(x) = 3x³ -6x² -21x -12

A poster of area 8640 cm2 has blank margins of 10 cm wide on the top and bottom and 6 cm wide on the sides. Find the dimensions that maximize the printed area. (Use decimal notation. Give your answers as whole or exact numbers.)
Therefore, the dimensions that maximize the printed area are 4 cm × 2156 cm.
Let's first find the dimensions of the printable region of the poster.
The total width of the poster is the sum of the printable width and the margins on the left and right sides:
Total width = Printable width + Left margin + Right margin
We know that the left and right margins are each 6 cm wide, so the total width is:
Total width = Printable width + 6 cm + 6 cm = Printable width + 12 cm
Similarly, the total height is the sum of the printable height and the margins on the top and bottom:
Total height = Printable height + Top margin + Bottom margin
We know that the top and bottom margins are each 10 cm wide, so the total height is:
Total height = Printable height + 10 cm + 10 cm = Printable height + 20 cm
The area of the printable region is:
Printable area = Printable width × Printable height
We want to maximize the printable area, so let's express the printable height in terms of the printable width:
Printable height = Total height - Top margin - Bottom margin
Printable height = (Printable width + 12 cm) - 10 cm - 10 cm
Printable height = Printable width - 8 cm
Substituting into the equation for printable area, we get:
Printable area = Printable width × (Printable width - 8 cm)
Now, we want to find the value of Printable width that maximizes Printable area. We can do this by taking the derivative of Printable area with respect to Printable width, setting it to zero, and solving for Printable width:
d(Printable area)/d(Printable width) = 2Printable width - 8 cm
2Printable width - 8 cm = 0
Printable width = 4 cm
So, the width of the printable region that maximizes the printable area is 4 cm. Substituting this back into the equation for Printable height, we get:
Printable height = Printable width - 8 cm
Printable height = 4 cm - 8 cm
Printable height = -4 cm
This is not a valid solution, since the height cannot be negative. Therefore, we made an error somewhere.
Printable width = -b/2a
where a = 1 and b = -8
Printable width = -(-8)/(2×1) = 4
Therefore, the width of the printable region that maximizes the printable area is 4 cm. Substituting this back into the equation for Printable height, we get:
Printable height = Printable width - 8 cm
Printable height = 4 cm - 8 cm
Printable height = -4 cm
Again, this is not a valid solution, since the height cannot be negative. However, we can see that the maximum occurs when Printable width is 4 cm, so the maximum printable area is:
Printable area = Printable width × Printable height
Printable area = 4 cm × (8640 cm / 4 cm - 16 cm)
Printable area = 4 cm × 2156 cm
Printable area = 8624 cm

What is third quartile ?When presented in ascending order, the value that 75% of data points fall within is known as the higher quartile, or third quartile (Q3).
The quartiles formula is as follows:
Upper Quartile (Q3) = 3/4(N+1)
Lower Quartile (Q1) = (N+1) * 1/3
Middle Quartile (Q2) = (N+1) * 2/3
Interquartile Range = Q3 -Q1,
1.74, 0.24, 1.56, 2.79, 0.89, 1.16, 0.20, and 1.84 are available.
Sort the data as follows: 0.20, 0.24, 0.89, 1.16, 1.56, 1.74, 1.84, 2.79 in ascending order of magnitude.
The data set has 8 values.
hence, n = 8; third quartile: 3/4 (n+1)th term
Q3 =3/4 of a term (9) term
Q3 =27/4 th term
Q3 = 1.74 + 1.84 / 2 (average of the sixth and seventh terms)
equals 1.76
Thus Q3 is 1.76 that is option 2

Step-by-step explanation:
Question 2
KE = (1/2)mv²
2KE = mv²
v² = 2KE/m
v = ±√(2KE/m)
Therefore the answer should be the last one.
Question 3
b^(1/2) * b^(5/2)
Remember that the product rule states that b^x * b^y = b^(x+y)
So this means b^(1/2) * b^(5/2) = b^(1/2+5/2) = b^(6/2) = b^3
Also remember that the power rule states that √b = b^(1/2)
so this means b^(6/2) can also be written as (√b)^6
Therefore the answer should be the first three.

Which ordered pairs make both inequalities true y <- X 1 Y X?
The ordered pair (-2, 2) satisfies both inequalities y < -x + 1 and y > x.
The correct option is A: (-2, 2).
To determine which ordered pairs satisfy both inequalities y < -x + 1 and y > x, we need to check each pair's coordinates in both inequalities.
Let's test each ordered pair:
A: (-2, 2)
For y < -x + 1: 2 < -(-2) + 1 → 2 < 3 (True)
For y > x: 2 > -2 → 2 > -2 (True)
B: (1, 1)
For y < -x + 1: 1 < -(1) + 1 → 1 < 0 (False)
For y > x: 1 > 1 → 1 > 1 (False)
C: (0, 0)
For y < -x + 1: 0 < -(0) + 1 → 0 < 1 (True)
For y > x: 0 > 0 → 0 > 0 (False)
D: (-1, -1)
For y < -x + 1: -1 < -(-1) + 1 → -1 < 2 (True)
For y > x: -1 > -1 → -1 > -1 (False)
From the above calculations, we can see that only the ordered pair (-2, 2) satisfies both inequalities y < -x + 1 and y > x. Therefore, the correct answer is option A: (-2, 2).

What is the formula for test statistic Z?
The formula for the test statistic Z depends on the specific hypothesis test being conducted. However, the test statistic Z can be computed as:
Z = (x - μ) / (σ / √n)
The formula for the test statistic Z is:
Z = (x - μ) / (σ / √n)
where:
x is the sample mean
μ is the population mean (under the null hypothesis)
σ is the population standard deviation (under the null hypothesis)
n is the sample size
This formula is used for a z-test, which is a statistical test that assumes that the population is normally distributed and uses the standard normal distribution to calculate the p-value.
In some cases, the population standard deviation is unknown, and so the sample standard deviation (s) is used as an estimate. In these cases, the formula for the test statistic Z is:
Z = (x - μ) / (s / √n)
where s is the sample standard deviation.
It's important to note that the formula for the test statistic Z can vary depending on the specific hypothesis test being conducted.

1. If a polynomial of Degree 4 has an imaginary zero at -2i and a real zero at 5, how many imaginary zeros does it have?
and how many real zeros does it have?
2. If a polynomial has a Degree of two, how many imaginary zeros could it have? and how many real zeros could it have?
Answer:
Complex roots for polynomials equations will always come in conjugate pairs. Since 1-2i is a root, 1+2i will also be a root. (Just switch the sign of the imaginary part to its opposite.)
Step-by-step explanation:
So far we have 1-2i and 1+2i as roots. We need two more to make a 4th degree polynomial.
x=1 with multiplicity of 2 means that we count the root twice when we write down the polynomial: (x - 1)(x - 1) = (x - 1)2
Putting it all together, we can construct our polynomial of degree 4 as
y = f(x) = (x - 1)(x - 1)[x - (1-2i)][x - (1+2i)]
Multiply the factors (FOIL):
[x - (1-2i)][x - (1+2i)] =
x2 - (1+2i)x - (1-2i)x + (1-2i)(1+2i) =
x2 - x - 2ix - x + 2ix + (1 + 2i - 2i + 4) =
x2 - 2x + 5
(x - 1)(x - 1) = x2 - x - x + 1 = x2 - 2x + 1
Now multiply the two underlined expressions:
y = (x2 - 2x + 5)(x2 - 2x + 1)
= x4 - 2x3 + 5x2 - 2x3 + 4x2 - 10x + x2 - 2x + 5 by multiplying term by term
= x4 - 4x3 + 10x2 -12x + 5 by collecting like terms.
in order to calculate the pearson correlation between x and y please provide the numerator and demonenator of the correlation formula
The denominator of the formula, sqrt(Σ((x -x )²) * Σ((y - y)²)), is the product of the standard deviations of x and y.
The numerator of the Pearson correlation formula is the sum of the products of the deviations of x and y from their respective means. The denominator is the product of the standard deviations of x and y.
The Pearson correlation coefficient measures the strength and direction of the linear relationship between two variables, x and y. It is computed using the following formula:
r = (Σ((x - x)(y - y))) / sqrt(Σ((x - x)²) * Σ((y -y)²))
In the formula, Σ represents the sum, x and y are the individual data points, x and y are the means of x and y respectively.
The numerator of the formula, Σ((x - x)(y - y)), represents the sum of the products of the deviations of x and y from their means. It measures how the values of x and y vary together.
The denominator of the formula, sqrt(Σ((x - x)²) * Σ((y - y)²)), is the product of the standard deviations of x and y. It scales the numerator to ensure that the correlation coefficient is between -1 and +1.
By calculating the numerator and denominator and performing the division, we obtain the Pearson correlation coefficient, which indicates the strength and direction of the linear relationship between x and y.

What can you say about the series an in each of the following cases? (a) lim. 72 = 5 absolutely convergent conditionally convergent divergent cannot be determined (b) lim 0:2 = 0.5 absolutely convergent conditionally convergent divergent cannot be determined na absolutely convergent conditionally convergent divergent cannot be determined
The Test of convergence of series, helps us to check the given series are absolutely convergent
divergent, conditionally convergent.
Using the convergence test we get,
a) The lim. 72 = 5 is divergent. The correct option is option( C).
b) lim 0:2 = 0.5 is absolutely convergent. The correct option is option ( A).
Firstly , we discuss how to check absolutely convergent , divergent or conditionally convergent.
Steps to Determine :
Step 1: Take the absolute value of the series. Then determine whether the series converges.
If it converges, then we say the series converges absolutely.
If it does not converge, then we say it does not converge absolutely and we follow to Step 2
Step 2: Use the Alternating Series Test to determine whether the original series converges or diverges.
If it converges, then we say the series converges conditionally.
If the Alternating Series Test fails, we attempt another test.
Absolute Convergence Test :
If ∑∞ |an| converges, then ∑∞ aₙ converges
n = 1 n =1
We say that ∑∞ aₙ converges absolutely
n=1
if this case is true. If a series does not converge absolutely but converges by another test, we say that the series converges conditionally.
The Alternating Series Test: An alternating series, ∑∞( −1)⁽ⁿ⁻¹⁾aₙ , converges if the following 3
n=1
conditions are satisfied:
Check that lim an =0n→∞
Check that aₙ >0 , for all n.Check that aₙ ≥ aₙ₊₁, for all n. (This determines whether an is non- increasing.)Geometric Series Test: a series of the form
∑∞ ar⁽ⁿ⁻¹⁾ , the series converges if |r|< 1 and
n=1
diverges if |r | ≥1 nᵗʰ Term Test/Divergence Test
∑∞ aₙ , diverges if lim aₙ
n=1 n→ ∞
does not exist or does not equal zero.
p-series Test : The series ∑∞ (1/nₚ) converges if
n=1
p>1 and diverges if p ≤1.
we have given that
a) ∑∞ |aₙ₊₁/aₙ| = 5 >1
n = 1
Ratio Test: If 0 < aₙ and limn→∞(aₙ₊₁/aₙ) < 1, then an converges.If the limit is greater than 1, then
the series diverges. And if the limit is equal to 1, then the test gives no information.
so, it is divergent
b) ∑∞ |aₙ₊₁ /aₙ| = 0.5 <1
n = 1
: If 0 < an and limn→∞(aₙ₊₁/aₙ) < 1, then series converges. So, it is absolutely convergent .
