Answer:
When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection) to see where the new figure will be located.
Step-by-step explanation:
The area of a square is given by A= s2 where s is the length of each side of the square if the area of a square room is 64 square meters what is the length of 1 side of the room in meters
9514 1404 393
Answer:
8 m
Step-by-step explanation:
Using the given information, we know that ...
64 m^2 = A = s^2
(8 m)^2 = s^2
8 m = s
The length of one side of the room is 8 meters.
Prove: a^2+b^2/2 ≥ab
We know that the square of any number is greater than or equal to zero ;
So if have a number like x :
[tex]( {x})^{2} \geqslant 0[/tex]
_________________________________
Now we have a number which is
( a - b ) ;
So we have :
[tex]( {a - b})^{2} \geqslant 0 [/tex]
##############################
Reminder :
[tex]( {a - b})^{2} = {a}^{2} - 2ab + {b}^{2} [/tex]
##############################
So we have :
[tex] {a}^{2} - 2ab + {b}^{2} \geqslant 0 [/tex]
Both sides plus 2ab :
[tex] {a}^{2} + {b}^{2} \geqslant 2ab [/tex]
Divided both sides by 2 :
[tex] \frac{ {a}^{2} + {b}^{2} }{2} \geqslant ab \\ [/tex]

And we're done.

A teacher can spend as much as
$125.00 to take students to a movie.
A movie theater charges a
$10.00 group fee and
$5.50 per ticket.
Which of the following inequalities represents the problem and could be solved to find the maximum number of students,
x, who could attend the movie?
The maximum number of students, x, who could attend the movie are,
⇒ x ≈ 21
What is Inequality?A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
A teacher can spend as much as $125.00 to take students to a movie.
And, A movie theater charges a $10.00 group fee and $5.50 per ticket.
Let maximum number of students, x, who could attend the movie = x
Hence, We can formulate;
5.50x + 10 ≤ 125
Solve for x;
5.50x ≤ 125 - 10
5.50x ≤ 115
x ≤ 115 / 5.50
x ≤ 20.90
x ≈ 21
Thus, The maximum number of students, x, who could attend the movie are,
⇒ x ≈ 21

In 2010, the average finishing time for marathons across the US was approximately 278 minutes, with a standard deviation of approximately 63 minutes. What finishing time defines the fastest 7.93% of runners?
Answer:
336 minutes
Step-by-step explanation:
Mean finishing time: 278 minutes
Standard Deviation: 63 minutes
Confidence interval: [278 - 63] , [278 + 63] = [215 , 341] minutes
What finishing time defines the fastest 7.93% of runners?
This means the 7.93% of time closest to the upper limit of 341 minutes
341 - 215 ≡ 63 × 2 = 126
7.93% of 126 = 0.0793 × 126 = 9.9918
341 - 9.9918 = 331.0082
Hence the finishing time that defines the fastest 7.93% of runners has an interval of [331 , 341] minutes with a mean or average of 336.0041 ≅ 336 minutes

The height of a golf ball hit in the air is modeled by the equation ℎ(t)=−16t2 + 48t, where ℎ(t) represents
the height, in feet, and t represents the number of seconds that have passed since the ball was hit.
Complete the statement about the function for ℎ(2)=32
If ℎ(2)=32 , then the ball reached a height of _________ feet after _________ seconds.
Answer:
16 feet, 2 seconds
Step-by-step explanation:
as the problem state that h= height and t = time, to get the h you need to isolate it so we divide it by 2 and we get 16 feet. The 2 are already in the problem h(2).
Evaluate the function: f(n) = n + 4

Need help with number 13
Answer:
x = 19
Step-by-step explanation:
the question tells you that the angle CBD is 90°.
so, that means that angle DBE and angle CBE add up to 90.
using this, you can make the following equation:
2x - 1 + 5x - 42 = 90
2x + 5x + -43 = 90
7x - 43 = 90
add 43 to both sides
7x = 90 + 43
7x = 133
x = 133/7
x = 19
Find the volume of a right circular cone that has a height of 13 in and a base with a
circumference of 5.1 in. Round your answer to the nearest tenth of a cubic inch.
Answer:
Step-by-step explanation:
the formula for finding the volume of a cone would be V= 3.14 r sqaured * h/3
so plug that in and it would be 3.14(5.1) sqaured * 13/3
3.14 is the formula of pie which is in the formula for finding the volume of
5.1*5.1= 26.01
3.14* 26.01= 81.67
13/3= 4.34
81.67* 4.34= 354.45
The volume of a right circular cone that has a height of 13 in and a base with a circumference of 5.1 inches is 8.97824.
Calculation of the volume of right circular cone:
Since
We know that
Volume = [tex]\pi r^2 \frac{h}{3}[/tex]
Since the circumference is 5.1 inches
So here the radius be like
Circumference = [tex]2\pi r[/tex]
5.1 = 2(3.14) r
r = 0.8121
Now the volume should be
[tex]= 3.14 \times (0.8121)^2 \frac{13}{3}[/tex]
= 8.97824
Hence, The volume of a right circular cone that has a height of 13 in and a base with a circumference of 5.1 inches is 8.97824.

12.) Given the following information, determine which lines, if any, are parallel. State the converse that justifies your answer. Pleaseee helppp
Answer:
Step-by-step explanation:
Given Parallel lines Converse
a. ∠13 ≅ ∠17 a║c Corresponding angles
b. ∠4 ≅ ∠9 d║e Exterior alternate angles
c. m∠20 + m∠21 = 180° a║b Consecutive interior angles
d. ∠8 ≅ ∠19 Vertical angles
e. ∠10 ≅ ∠23 b║c Interior alternate angles
f. m∠14 + m∠17 = 180° a║c Consecutive interior angles
From the given diagram and information, it can be concluded that lines a, b, and c are parallel, and lines d and e are parallel.
The given lines in the diagram are a, b, c, d, and e.
a. It is given that the measure of angle 13 is equal to that of angle 17.
Now, these two angles are made by lines a, c, and d. Now, the angles are corresponding and equal, and hence, lines a and c will be parallel.
b. It is given that the measure of angle 4 is equal to that of angle 9.
These two angles are made by lines d, e, and b. Now, the angles are alternate exterior and equal, and hence, lines d and e will be parallel.
c. It is given that the sum of the measure of angles 20 and 21 is equal to 180 degrees.
These two angles are made by lines a, b, and e. Now, the angles are supplementary and their sum is 180 degrees, and hence, lines a and b will be parallel.
d. It is given that the measure of angle 8 is equal to that of angle 19.
These two angles are vertically opposite angles between lines a and e.
e. It is given that the measure of angle 10 is equal to that of angle 23.
These two angles are made by lines b, c, and e. Now, the angles are alternate interior and equal, and hence, lines b and c will be parallel.
f. It is given that the sum of the measure of angles 14 and 17 is equal to 180 degrees.
These two angles are made by lines a, c, and d. Now, the angles are supplementary and their sum is 180 degrees, and hence, lines a and c will be parallel.
Therefore, it can be concluded that lines a, b, and c are parallel, and the lines d and e are parallel.
