Answer:
The square root is the inverse operation to the power of 2, so that whenever you take a number and perform both actions on it, you get the same number back.
Sample Answer: Squaring and square root are inverses, so one should "undo" the other. That is, squaring the square root of a number results in the number. Using the power of a power rule, you multiply the exponents. Since a number to the first power is itself, the product of the exponents must equal 1. This means that the power of the square root must be the reciprocal of 2, or one half.

En la inaguracion de unos juegos olimpicos, los 38 representantes de una nacion quieren desfilar formando columnas de 6¿es posible?¿de que modo podria desfilar formando columnas iguales?
Answer:
a) No
b) Sí
Step-by-step explanation:
a) En la inauguración de unos Juegos Olímpicos, los 38 representantes de una nación quieren desfilar en columnas de 6, ¿es posible?
Esto se calcula como
38 representantes / 6 columnas
= 6 2/6 = 6 1/3 columnas
No, no es posible, tendríamos 7 columnas con 6 columnas con representantes iguales de 6 y la séptima columna tendría solo 2 representantes allí
b) ¿Cómo podrían desfilar en columnas iguales?
Sí pueden
Esto se calcula como 38 representantes ÷ 2
= 19 columnas
Podemos tener 19 columnas con 2 representantes cada una

If a^2+b^2=5 and a+b=3, then ab=
Answer:
ab = 2
Step-by-step explanation:
You know that ...
(a +b)^2 = a^2 +2ab +b^2
Rearranging, we can solve for ab ...
2ab = (a^2 +b^2) -(a +b)^2
ab = ((a +b)^2 -(a^2 +b^2))/2 = (3^2 -5)/2
ab = 2

Answer:
x = 134
Step-by-step explanation:
Exterior angle = sum of opposite interior angles
= 90 + 44 = 134
OR
Sum of angles of triangle = 180
that is,
90 + 44 +y = 180
y = 180 - 134
y = 46
x + y = 180 [ straight line angles ]
x + 46 = 180
x = 180 - 46 = 134
Answer:
x = 134
Step-by-step explanation:
triangle sum theorem states that the sum of all angles within a triangle is equal to 180 degrees. using this we can figure out that the missing angle in the triangle is 46.
a straight line is also equal to 180 degrees, so to find the adjacent angle, we subtract 46 from 180, and we get 134

Pls help there’s the info above
Answer:
When you're given a line, you can find the rise over the run also known as the slope using a graph, calculating it using the formula, or using a table with two points you've been given from the line. Once you find the slope find the y-intercept which is the point at which the line intercepts with the y-axis of the cartesian plane. I also added some attachments of my own work and an explanation of slope.

Determine the x and y intercepts for the line 3x – 5y + 15 = 0. Show your work.
Answer:
Step-by-step explanation:
The x and y intercepts occur when either x or y = 0
For the y intercept, x = 0
3(0) - 5y + 15 = 0
- 5y + 15 = 0 Subtract 15 from both sides.
-5y = - 15 Divide by - 5
-5y / -5 = - 15/-5
y = 3
For x intercept, y = 0
3x - 5(0) + 15 = 0
3x + 15 = 0 Subtract 15 from both sides
3x = - 15 Divide by 3
3x/3 = - 15/3
x = - 5
xintercept = (-5,0)
yintercept = (0,3)
Twelve is added to 5x and equals - 3. Find the value of x.
Answer:

x=3
Answer:
5x+12=-3
5x=-15
x=-3

Step-by-step explanation:
In the figure shown PS = RQ. which theorem can be used to prove Triangle SQR = Triangle QSP?
I'm not sure which answer it is can you help me?
Answer:
HL (hypotenuse leg)
Step-by-step explanation:
From the diagram, we have two sides that are congruent
The side QS is common to both triangles
Also, we have it that the side PS and QR are congruent
What this mean is that we have two sides that are already the same
Now, looking at the right angle position in both, we can see that QR and PS represents the hypotenuse of individual right angles
Using the HL congruence statement, since we have it that the hypotenuse one side is already congruent, we can conclude that the last side too is congruent and as such both triangles are congruent to each one another

Joshua drove his car a distance of 449.6 miles, and it required 12.9 gallons of gasoline (petrol). How many liters of fuel will it take to go 100 kilometers?
Answer:
6.75L of fuel are needed
Step-by-step explanation:
To solve this question we need to convert the miles to km and the gallons to liters in order to find the km/L that the car is doing:
km -1km = 0.621371miles-
449.6miles * (1km / 0.621371 miles) = 723.56km
L -1L = 0.264172gal-
12.9gal * (1L / 0.264172gal) = 48.83L
km/L:
723.56km / 48.83L= 14.82km/L
The liters the car takes to go 100km are:
100km * (1L / 14.82km) = 6.75L of fuel are needed

Answer:
[tex]y=0.5x+2[/tex]
Step-by-step explanation:
Finding the inverse of a function is essentially finding the complete opposite of a given function. An easy trick can be used to find the inverse of a function. This trick is essentially thinking of the evaluator (f(x)) as another variable. Solve the function for (x) in terms of (f(x)); use inverse operations to do so. After completing this process, rewrite the function such that it is in the inverse function notation; switch the position of the (f(x)) and the (x), then indicate that it is an inverse function.
[tex]f(x)=2x-4[/tex]
Inverse operations,
[tex]f(x)=2x-4[/tex]
[tex]f(x)+4=2x[/tex]
[tex]\frac{f(x)+4}{2}=x[/tex]
Simplify,
[tex]0.5f(x)+2=x[/tex]
Rewrite in inverse function notation,
[tex]f^-^1(x)=0.5x+2[/tex]
[tex]y=0.5x+2[/tex]

Answer:
x = 80
Step-by-step explanation:
Both angles together form 180, therefore x is 80
Answer:
x = 80
Step-by-step explanation:
100 and x form a straight line so they add to 180
x+100 =180
Subtract 100 from each side
x = 180-100
x = 80

find the ratio in which the point (3,y) divides the line joining the point (9,8) and (-4,-6) hence find the value of y
Answer:
m1:m2 = 6:7
y = 7 (Approx.)
Step-by-step explanation:
Given:
Dividing point (3, y)
Two points (9 , 8) , (-4 , 6)
Find:
Ratio
Value of y
Computation:
X = [(m1)(x2) + (m2)(x1)] / [m1 + m2]
3 = [(m1)(-4) + (m2)(9)] / [m1 + m2]
3m1 + 3m2 = -4m1 + 9m2
7m1 = 6m2
m1 / m2 = 6 / 7
m1:m2 = 6:7
Y = [(m1)(y2) + (m2)(y1)] / [m1 + m2]
y = [(6)(6) + (7)(8)] / [6 + 7]
y = [36 + 56] / 13
y = 92 / 13
y = 7.07
y = 7 (Approx.)
