What is the value of the positive zero of the function , f, defined by f(x) =x^2-121
Answer:
The positive zero is 11
Step-by-step explanation:
Given in the question an equation,
f(x) =x² - 121
We are asked to find the positive zero of f(x)
means x > 0 for which f(x) = 0
so,
x² - 121 = 0x² = 121
Take square root on both sides of the equation
√x² = √121
x = ±11
which means that x = 11 and x = -11
Since x > 0 so we will reject x =-11 and we will accept x = 11
Answer: 11
Step-by-step explanation:
You need to substitute [tex]f(x)=0[/tex] into the function given:
[tex]f(x) =x^2-121\\0 =x^2-121[/tex]
Now you need to solve for the variable "x", to do this, first you must add 121 to both sides of the function:
[tex](121)+0=x^2-121+(121)\\121=x^2[/tex]
Now apply square root to both sides of the function. Then, you get:
[tex]\±\sqrt{121}=\±\sqrt{x^2}\\\\\±\sqrt{121}=x\\\\x_1=11\\x_1=-11[/tex]
The value of the positive zero of the function is 11.
A hexagonal pyramid has a volume of 144 cubic millimeters and a height of 4 millimeters. What is the area of the base of pyramid
The answer is:
The area of the base of the pyramid is:
[tex]BaseArea=108mm^{2}[/tex]
Why?We are given the volume and the height of the hexagonal pyramid, so, to calculate the base of the area, we need to use the following formula:
[tex]Volume=\frac{1}{3}*BaseArea*Height[/tex]
So, we are given the following information:
[tex]Volume=144mm^{3}\\\\Height=4mm[/tex]
Then, substituting the given information and isolating the base area, we have:
[tex]Volume=\frac{1}{3}*BaseArea*Height[/tex]
[tex]144mm^{3} =\frac{1}{3}*BaseArea*4mm\\\\144mm^{3}*\frac{3}{4mm}=BaseArea\\\\BaseArea=108mm^{2}[/tex]
Hence, the area of the base of the hexagonal pyramid is equal to:
[tex]BaseArea=108mm^{2}[/tex]

If you factor 4x^2-49y^2 what’s the answer
Answer:
(2x - 7y)(2x + 7y)
Step-by-step explanation:
4x^2-49y^2 is the difference of two squares: (2x)² - (7y)².
This is a case of "special products and factoring."
Since a² - b² = (a - b)(a + b),
(2x)² - (7y)² = (2x - 7y)(2x + 7y)
Solution:
The given Equation is 4x² - 49y²
Spilt it in the form of a² - b² :
☞4x² - 49y²
☞ (2x)² - (7y)²
☞ ( 2x + 7)(2x -7 )
Answer:
More information: { Identity Used }
☞ a² - b² = (a + b)(a-b)
☞ (a + b)² = a² + b² + 2ab

A) 2
B) 1
C) 0.5
D) 0.25
E) 0.1
Random answers will be reported!
Answer:
Sin E=0.50
Step-by-step explanation:
Here we are given that DE || AB, and DB and AE are traverse lines to them meeting at point F.
By the properties of parallel lines intersected by a transverse we know that the alternate interior angles are equal.
If we extend DE and AE on both sides , we can see that A and E are equal as they forms alternate interior angles.
Hence
A=E
Sin A = Sin E
0.50=Sin E
Answer:
I got sin E = 0.5
Thus answer choice C being the correct choice

An inscribed angle is an angle formed by two radii that share an endpoint. (true or false)
Answer:
False
Step-by-step explanation:
False. An inscribed angle is formed by two chords (inside a circle).
Note: A central angle is an angle formed by two radii that share an endpoint.
The statement about an inscribed angle being formed by two radii is false. An inscribed angle has its vertex on the circle and is formed by two intersecting chords, whereas a central angle has its vertex at the center of the circle and is formed by two radii.
The statement that an inscribed angle is an angle formed by two radii that share an endpoint is false. An inscribed angle in a circle is actually formed by two chords that intersect on the circle. The vertex of the inscribed angle lies on the circle and its sides are made up of two chords of the circle. By contrast, an angle formed by two radii that share an endpoint is called a central angle. The central angle's vertex is the center of the circle, and it intercepts an arc.
What is the simplified form of the equation 4/5n - 3/5 = 1/5n?
Answer:
n = 1 if you meant "(4/5)n - (3/5) = (1/5)n"
Step-by-step explanation:
There's some ambiguity here. Did you mean (4/5)n or did you
4
mean --------- ? Please use parentheses to eliminate this ambiguity.
5n
I'm going to assume that you meant to type in (4/5)n - (3/5) = (1/5)n.
Then we have (3/5)n = 3/5, or n = 1
The simplified form of the equation (4/5)n - (3/5) = (1/5)n is n=1. This is obtained by solving for n since it is an algebraic equation.
Find the value of n:Given that,
(4/5)n - (3/5) = (1/5)n
Taking terms with n to one side and constant to other side of the equation,
(4/5)n - (1/5)n = (3/5)
(4-1/5)n = (3/5)
(3/5)n = (3/5)
⇒n = 1
Hence the simplified form of the equation (4/5)n - (3/5) = (1/5)n is n=1.

Which of the following statements about the image below is true?
Answer:
The measure of SWX is 108.
Step-by-step explanation:
TX and QS are not perpendicular.
QRT and TRU are complementary (add to 90) not supplementary (add to 180)
The measure of SWX is 108 because angles on a line add to 180, and RWS is 72. 180 - 72 = 108
Answer:
The measure of <SWX is 108°
The second answer is actually Complementary.
He rest of the answers are pretty obvious no’s.

Which of the following statements is true?
A. The median of box plot A is greater than the median of box plot B.
B. Both the box plots A and B have the same median.
C. The interquartile range of box plot A is greater than the interquartile range of box plot B.
D. The median of box plot B is greater than the median of box plot A.
Answer:
the answer is D: the median of box plot B is greater than the median of box plot A.
Step-by-step explanation:
Answer: D. The median of box plot B is greater than the median of box plot A.
Step-by-step explanation:
We know that in a box-whisker plot, the vertical present in the box represents the median value of data and the length of box along the number line represents the interquartile range.
In the given picture, it can be seen that the box B is longer than box A.
It mean that the interquartile range of box plot B is greater than the interquartile range of box plot A.
Also, the vertical line in box A is present between 15 and 20 on number line but in box B it is present between 25 and 30.
It means that the median of box plot B is greater than the median of box plot A.
In February, Alex has 1,518 visitors to his websit. In March, he had 1380 visitors to his website. What is the percent decreased of the number of visitors to Alec’s website from February to March ? If necessary, round to nearest tenth of a percent ???
Answer:
The percent decreased of the number of visitors to Alec’s website
from February to March is 9.1%
Step-by-step explanation:
* Lets talk about the percentage of increase and decrease
- Percent of Increase (Decrease) =
(amount of increase or decrease ÷ original amount) × 100%
- Increase {New amount > Original amount}
- Decrease {Original amount > New amount}
* Now lets solve the problem
- The number of visitors in February is 1518
- The number of visitors in March is 1380
- The number in March < the number in February
∴ The decreasing amount = 1518 - 1380 = 138 visitors
∵ The original number = 1518
∴ The percent decreased = (138 ÷ 1518) × 100% = 9.1%
* The percent decreased of the number of visitors to Alec’s website
from February to March is 9.1%

Answer:
67
Step-by-step explanation:
Total
= 43 + 69 + 48 + 37 + 85 + 57 + 95 + 102
= 536
Mean
= 536 ÷ 8
= 67
The mean of the given set of numbers is 67.
Explanation:The mean, also known as the average, is calculated by adding up all the numbers in a set and then dividing the sum by the total number of values in the set.
To find the mean of the set of numbers 43, 69, 48, 37, 85, 57, 95, and 102, you need to add all the numbers together and then divide the sum by the total number of values, which is 8.
43 + 69 + 48 + 37 + 85 + 57 + 95 + 102 = 536
536 ÷ 8 = 67
Therefore, the mean of the given set of numbers is 67.

In spherical geometry lines are called _____
Answer:
the answer is: a great circle
In spherical geometry, lines are called geodesics, which are represented by great circles on the surface of a sphere. These circles are the spherical equivalents of straight lines in Euclidean geometry and highlight the unique properties of spherical geometry, such as the different rules for angles and parallel lines.
In spherical geometry, lines are referred to as geodesics. Unlike in Euclidean geometry where lines are the shortest distance between two points on a plane, in spherical geometry, geodesics are the shortest paths on the surface of a sphere and are represented by great circles. Great circles are the largest circles that can be drawn on a sphere, with their centers coinciding with the center of the sphere. This concept is crucial in areas such as cartography and navigation where the Earth's surface needs to be understood as a sphere rather than a flat plane.
For example, in creating a triangle on the Earth's surface with one corner at the north pole and the other two at the equator separated by 90 degrees of longitude, the sum of its interior angles exceeds 180 degrees. This defies a fundamental rule of Euclidean geometry, indicating the unique properties of spherical geometry where traditional parallel lines do not exist and the axioms of Euclidean geometry are not entirely applicable.
Find the area of the trapezoid by decomposing it into other shapes.
A) 60 cm2
B) 69 cm2
C) 84 cm2
D) 99 cm2
Answer:
99 cm^2
Step-by-step explanation:
Solution 1: Don't decompose and instead use the trapeziod area theorem. (b1+b2)/2 * h. Using this we plug in the two bases and get (23+10)/2 *6 -->
16.5*6=99cm2
Solution 2: You follow the rules and decompose the trapeziod. Split it into two triangles and a rectangle. The area of the triangle on the left is (b*h)/2 which is equal to (3*6)/2 which is 9 cm2. Spliting the trapeziod gives the rectangle dimensions of 10x6. 10*6= 60cm2. Finally we must find the area of the triangle on the right. The height is 6cm in the diagram and the base would be the full base of the trapeziod(20+3)-(10+3) --> 23-13=10. Using the area formula for the triangle gives us 10*6/2 = 30cm2. To find the full area we must add all the shapes up, 9+60+30 = 99cm2
