given area (shown in image below)?
x +9
x² + 11x + 18
(My answer is a guess so please show your work if you answer this question!)
thank you:)
Answer:
x + 2
Step-by-step explanation:
Area = x² + 11x + 18
length = x + 9
width = ?
Area = length x width
Factor the polynomial x² + 11x + 18:
length x width = (x + 9)(x + 2) = x² + 11x + 18
The length is x + 9, therefore the width is x + 2
the set of lowercase words of length 8 in which each distinct letter appears exactly twice (e.g., approora, yetiteyi, tunantau).
There are 12 lowercase words of length 8 in which each distinct letter appears exactly twice.
What are the Lowercase Words?To form a lowercase word of length 8 in which each distinct letter appears exactly twice, we can choose 4 distinct letters from the English alphabet and then arrange them in pairs in the word. The number of ways to choose 4 distinct letters from 26 is:
C(26, 4) = 26! / (4! * 22!) = 14,950
Once we have chosen 4 distinct letters, we can arrange them in pairs in the word in the following way:
Choose the first pair: we can choose any of the 4 letters, so there are 4 options.Choose the second pair: we can choose any of the remaining 3 letters, so there are 3 options.Arrange the pairs: there is only one way to arrange the pairs.Therefore, the total number of such words is:
4 * 3 * 1 = 12
Thus, there are 12 lowercase words of length 8 in which each distinct letter appears exactly twice. Here are all the possible words:

what that two numbers when multiplied give 600 and when added give 59
Answer:
Step-by-step explanation:
Let the 2 numbers be x and y
From the problem we have that
x * y = 600 and x + y = 59
From x + y = 59 -> x = 59 - y
Plug x = 59 - y to x * y = 600 we have
(59 - y) * y = 600
-> 59y - y^2 = 600
-> -y^2 + 59y - 600 = 0
-> y = \((59 - \sqrt{1081})/2\) or \((59 + \sqrt{1081})/2\)
Then we could plug the answers in and find x because x = 59 - y

The volume of the solid obtained by rotating the region bounded by the curve y = 1 - (x - 5)² in the first quadrant about the y-axis is 51π cubic units.
What is the volume of the solid obtained by rotating the region in the first quadrant bounded by the given curve about the y - axis?To find the volume of the solid obtained by rotating the region bounded by the curve y = 1 - (x - 5)² in the first quadrant about the y-axis, we can use the method of cylindrical shells.
The formula for the volume using cylindrical shells is:
V = 2π ∫ [a, b] x * h(x) dx
Where:
- V is the volume of the solid
- π represents the mathematical constant pi
- [a, b] is the interval over which we are integrating
- x is the variable representing the x-axis
- h(x) is the height of the cylindrical shell at a given x-value
In this case, we need to solve for x in terms of y to express the equation in terms of y.
Rearranging the given equation:
x = 5 ± √(1 - y)
Since we are only interested in the region in the first quadrant, we take the positive square root:
x = 5 + √(1 - y)
Now we can rewrite the volume formula with respect to y:
V = 2π ∫ [c, d] x * h(y) dy
Where:
- [c, d] is the interval of y-values that correspond to the region in the first quadrant
To determine the interval [c, d], we set the equation equal to zero and solve for y:
1 - (x - 5)² = 0
Expanding and rearranging the equation:
(x - 5)² = 1
x - 5 = ±√1
x = 5 ± 1
Since we are only interested in the region in the first quadrant, we take the value x = 6:
x = 6
Now we can evaluate the integral to find the volume:
V = 2π ∫ [0, 1] x * h(y) dy
Where h(y) represents the height of the cylindrical shell at a given y-value.
Integrating the expression:
V = 2π ∫ [0, 1] (5 + √(1 - y)) * h(y) dy
To find h(y), we need to determine the distance between the y-axis and the curve at a given y-value. Since the curve is symmetric, h(y) is simply the x-coordinate at that point:
h(y) = 5 + √(1 - y)
Substituting this expression back into the integral:
V = 2π ∫ [0, 1] (5 + √(1 - y)) * (5 + √(1 - y)) dy
Now, we can evaluate this integral to find the volume
V = 2π ∫ [0, 1] (5 + √(1 - y)) * (5 + √(1 - y)) dy
To simplify the integral, let's expand the expression:
V = 2π ∫ [0, 1] (25 + 10√(1 - y) + 1 - y) dy
V = 2π ∫ [0, 1] (26 + 10√(1 - y) - y) dy
Now, let's integrate term by term:
\(V = 2\pi [26y + 10/3 * (1 - y)^\frac{3}{2} - 1/2 * y^2]\)] evaluated from 0 to 1
V = \(2\pi [(26 + 10/3 * (1 - 1)^\frac{3}{2} - 1/2 * 1^2) - (26 * 0 + 10/3 * (1 - 0)^\frac{3}{2} - 1/2 * 0^2)]\)
V = 2π [(26 + 0 - 1/2) - (0 + 10/3 - 0)]
V = 2π (25.5)
V = 51π cubic units

In circle O, central angle COD has a measure of 48. Find the measure of arc BC. In your final answer, include all your work
Answer:
Measure of arc BC = 132°
Step-by-step explanation:
Measure of the central angle COD = 48°
Therefore, measure of arc AB = 48°
Since, segment AC is a diameter and central angle for a diameter is 180°.
Measure of major arc ABC = 180°
measure of arc AB + measure of arc BC = 180°
48° + measure of arc BC = 180°
Measure of arc BC = 180° - 48°
= 132°

Complete Question
It has been found that 26% of men 20 years and older suffer from hypertension (high blood pressure) and 31.5% of women are hypertensive. A random sample 150 of each gender was selected from recent hospital records, and the following results were obtained.
Men. 43 patients had high blood pressure
Woman. 52 patients had high blood pressure.
Answer:
The 95% confidence interval is
\(- 0.1651 < p_m - p_f <0.0451\)
This mean that there is a 95 % confidence that the difference between the true proportions of male and female that are hypertensive is within this interval and given that the interval contains zero then there is no statistically significant difference between the genders that are hypertensive
Step-by-step explanation:
From the question we are told that
The sample size for male is \(n_1 = 150\)
The number of male that are hypertensive is \(m = 42\)
The sample size of female is \(n_2 = 150\)
The number of female that are hypertensive is \(q = 52\)
The proportion of male that are hypertensive is mathematically represented as
\(\r p_m = \frac{43}{150}\)
\(\r p_m = 0.287\)
The proportion of female that are hypertensive is mathematically represented as
\(p_f = \frac{52}{150}\)
\(p_f = 0.347\)
From the question we are told that confidence level is 95%, hence the level of significance is mathematically represented as
\(\alpha = 100 -95\)
\(\alpha =5\%\)
\(\alpha =0.05\)
Next we obtain the critical value of \(\frac{ \alpha }{2}\) from the normal distribution table, the value is
\(Z_{\frac{ \alpha }{2} } = 1.96\)
Generally the margin of error is mathematically represented as
\(E = Z_{\frac{\alpha }{2} } * \sqrt{\frac{ \r p_m (1- \r p_m )}{n_1} + \frac{ \r p_f (1- \r p_f )}{n_2} }\)
substituting value
\(E = 1.96 * \sqrt{\frac{ 0.287 (1- 0.287 )}{150} + \frac{ 0.347 (1- 0.347 )}{150} }\)
\(E = 0.1051\)
The 95% confidence interval is mathematically represented as
\((\r p_m - \r p_f ) - E < p_m - p_f < (\r p_m - \r p_f ) + E\)
substituting values
\(( 0.287 - 0.347 ) - 0.1051 < p_m - p_f <( 0.287 - 0.347 ) + 0.1051\)
\(- 0.1651 < p_m - p_f <0.0451\)
This mean that there is a 95 % confidence that the difference between the true proportion is within this interval and given that the interval contains zero then there is no statistically significant difference between the genders that are hypertensive.

which must be true in order for the relationship zyx~wvu to be correct
In order for the relationship zyx ~ wvu to be correct, the following conditions must be true:
Corresponding angles are congruent: The angles formed by matching vertices should have the same measures in both triangles. This ensures that the corresponding angles are equivalent.
Corresponding sides are proportional: The lengths of the sides that connect the corresponding vertices of the triangles should have a consistent ratio. This implies that the corresponding sides are proportional to each other.
These conditions are based on the definition of similarity between two triangles. If both the corresponding angles are congruent and the corresponding sides are proportional, then the triangles zyx and wvu are considered similar (denoted by ~).
Therefore, in order for zyx ~ wvu to be correct, the congruence of corresponding angles and the proportionality of corresponding sides must hold true.
