in surd form.
Answer:
[tex] {2}^{ \frac{3}{2} } = \sqrt[3]{ {2}^{2} }\\= \sqrt[3]{ {4}}[/tex]
The surd form is : [tex](\sqrt{2} )^3[/tex]
[tex](\sqrt{2} )^3=\sqrt{2}. \sqrt{2}. \sqrt{2}[/tex]
It gives in the approximate value is : 2.80
What is surd form?Surds are the square roots (√) of numbers that cannot be simplified into a whole or rational number. It cannot be accurately represented in a fraction. In other words, a surd is a root of the whole number that has an irrational value. Consider an example, √2 ≈ 1.414213. It is more accurate if we leave it as a surd √2.
We have from the question is:
Write in the surd form:
=> [tex]2^\frac{3}{2}[/tex]
Now, According to the definition:
Write like this:
[tex]2^\frac{3}{2}=((\sqrt{2} )^2)^\frac{3}{2}[/tex]
Cancel out the:
2 × 3/2 = 3
So, [tex](\sqrt{2} )^3=\sqrt{2}. \sqrt{2}. \sqrt{2}[/tex]
It gives in the approximate value is : 2.80

Answer:
C - The relationship represents a function because each input gives one unique output.
Step-by-step explanation:
To see if it is a function we can do the line test where we have a vertical line and "drag" it along the line. As long as it only hits the line once in every situation it is a function! We can see this passes and therefore the answer is c.
(why is it not d? you can have a non-linear line, but still have a function)

The edges on Zachary's snowboard are chlpped and dented from riding over rocks, so Zachary wants to buy a new one. He can't afford the board he wants, so he opens a hot chocolate stand near his house. Zachary figures out how many cups of hot chocolate he must sell to have enough money for the snowboard. One cold, snowy Saturday, Zachary sells 43 cups of hot chocolate. Now, he needs to sell 47 more cups to buy the snowboard. Which equation can you use to find the total number of cups c Zachary must sell to buy the snowboard?
Answer:
c-43=47
Step-by-step explanation:
Well this is kinda obvious.
He already sold 43 cups of hot choclate and he needed 47 more.
So the total amount of cups is (c) so we can make an equation like this
c-43 (since theres total which is unknown so ”c” and then Theres the already sold 43 cups).
c-43=47 (the 47 is the amount he needs to sell)
So final equation to determine total cups needed
c-43=47

Write down in terms of n, an expression for the nth term
of the following sequence
-8 -15 -22 -29 -36
Answer:
[tex]a_{n}[/tex] = - 7n - 1
Step-by-step explanation:
There is a common difference between consecutive terms , that is
- 15 - (- 8) = - 22 - (- 15) = - 29 - (- 22) = - 36 - (- 29) = - 7
This indicates the sequence is arithmetic with nth term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 8 and d = - 7 , then
[tex]a_{n}[/tex] = - 8 - 7(n - 1) = - 8 - 7n + 7 = - 7n - 1

Answer:
2/5 or .4 as a decimal
Step-by-step explanation:
we can't do anything in the Parentheses so we distribute the -2.5 giving us the equation
-10x+10=6
we subtract both sides by 10
so now our equation is
-10x=-4
we divide both sides by -10
this leaves us with -4/-10 which is simplified to 2/5 or .4 as a decimal

Answer:
Associative Property of Addition
Step-by-step explanation:
According to the Associative Property of Addition, when three real numbers are added, it makes no difference which two are added first.
(a + b) + c = a + (b + c)
Therefore, 8 + (2 + 6) = (8 + 2) + 6 is an example of the Associative Property of Addition.

Titus took 30 minutes to walk 2 miles at a constant
rate. Let d represent the distance Titus walks, in miles, after t minutes. Here are your constants of proportionality from the previous screen: 15 and 15. Write two different equations to represent the
relationship between d and t.
If Titus walked 7.5 miles at this same rate, how many
minutes would it take?
HEEEEEELLLLLPPPPP
Constant of proportionaility #1 2/30 = 1/15
Constant of proportionaility #2 d/t
1 distance divided by time
Relationship: equality
Reason: they all represent velocity and they tell us that velocity is constant.
-------------------------------------------------------
15 and 1/15 (answer)
Steps:
Given
Time (t) = 30 minutes
distance (d) = 2 miles
To determine the first constant of proportionality
Let time be directly proportional to distance.
t = kd
Where k is the constant of proportionality
Make k the subject
k = t/d
Substitute values for t and d
k = 30/2
k = 15
To determine the second,
Let distance be directly proportional to time.
d = kt
Make k the subject
k = d/t
Substitute values for d and t
k = 2/30
k = 1/15
Hence, the constant of proportionality are
15 and 1/15

Answer:
22.61°
Step-by-step explanation:
Help asap will give brainliest!!!!
Answer:
C
Step-by-step explanation:
ley y = f(x) and rearrange making x the subject
y = [tex]\frac{1}{x+5}[/tex] - 1 ( add 1 to both sides )
y + 1 = [tex]\frac{1}{x+5}[/tex] ( multiply both sides by (x + 5)
(y + 1)(x + 5) = 1 ← expand factors using FOIL
xy + 5y + x + 5 = 1 , that is
xy + x + 5y + 5 = 1 ( factor first/second and third/fourth terms on left side )
x(y + 1) + 5(y + 1) = 1 ← factor out (y + 1) from each term on left side
(y + 1)(x + 5) = 1 ( divide both sides by (y + 1) )
x + 5 = [tex]\frac{1}{y+1}[/tex] ( subtract 5 from both sides )
x = [tex]\frac{1}{y+1}[/tex] - 5
Change y back into terms of x with x = [tex]f^{-1}[/tex] (x) , then
[tex]f^{-1}[/tex] (x) = [tex]\frac{1}{x+1}[/tex] - 5 where x ≠ - 1

My teacher asked for me to specify which two theorems I used. And I don't know. Here is my work can someone help please.
Isosceles Right Triangle Reflection to prove ASA Congruence
1. Answer the following questions:
A. What line of reflection did you choose for your transformation?
- I used the y-axis as my line of reflection.
B. How are you sure that each point was reflected across this line?
- I am sure because the sides are all opposite, but the numbers stayed the same.
C. What reflection rule did you apply to your triangle?
- (x, y) ➟ (-x, y)
2. What other properties exist in your triangle? Discuss at least two theorems you learned about in this module that apply to your triangle. Make sure to show evidence by discussing your triangle's measurements.
- I learned that if two sides of my triangle are congruent then the angles opposite of them are congruent as well. The third angle is 90 degrees.
3. Did your triangle undergo rigid motion? Explain why.
- Yes, it did. It did because the distance and position stayed the same while the points and the plane moved.
Answer:
Actually you did everything right
Step-by-step explanation:
yes
This question requires proving congruency of triangles in a given co-ordinate system we by use of ASA(angle side angle) theorem.

The hypotenuse will be [tex]\sqrt{2}[/tex] times of the equal sides.
A. We have chosen x-axis as a line of refection.Reflection along x-axis idicates rotation of 180° along x axis.
B. We are sure that each point is reflected accross this line because base has same magnitude but the signs have changed and rotation along x-axis doesn't change the value of y co-ordinate.
C. Rotaion along X-axis by 180°.

Please help me solve this ASAP
Answer:
$21
Step-by-step explanation:
Let the amount Lori bought the shirt and the hat be $x, if she bought them at half off sale, the initial price of both item will be 2 × $x
If she spent $21 on both items, the initial price will have been 2 x $21 = $42 where x is $21
Original price of the hat and shirt is therefore $42. Since both are on half off sale, the initial price is the hat will be $42/2 = $21
Which function passes through the points (2,3) and (4,4)
Answer:
y = 1/2x + 2
Step-by-step explanation:
First, we find the slope of the line by subtracting the x- and y-values of each point, and dividing that:
(4-3)/(4-2) = 1/2
So, our slope is 1/2. Then, we insert this into a y = mx + b equation using one of our points to find the y-intercept (b). I used the point (2, 3):
3 = 1/2(2) + b
3 = 1 + b
b = 2
Now that we have our slope and the y-intercept, we can create a function: y = 1/2x + 2.
Answer:
C, Because if you draw a graph, the line y=1/2x+2 lines up with (2,3) and (4,4),
Sally is 3 years older than Jill was 5 years ago. Write an algebraic expression for both of their ages. If Jill is 10, how old is Sally?
Answer: 13 (and Sally will always be 3 years older than Jill)
Step-by-step explanation:
Let S and J stand for Sally and Jill's ages. We are told:
(S-5) = (J-5)+3 [Sally is 3 years older than Jill was 5 years ago] The 5 years ago is the reason for the (S-5) and (J-5) expressions.If Jill is 10, how old is Sally?
(S-5) = (J-5)+3
(S-5) = (10-5)+3
S-5 = 8
S = 13
We actually don't really need an equation for solving this, other than the question asks us to write one. It doesn't matter how many years later, since Sally is 3 years older, she will always remain 3 years older, if we ignore the likelihood that the statement doesn't hold true for the period between their actual birthdays.

Using the cosine ratio in the right triangle
cos x = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{HJ}{GJ}[/tex] = [tex]\frac{45}{52}[/tex] , then
x = [tex]cos^{-1}[/tex] ( [tex]\frac{45}{52}[/tex] ) ≈ 30.1° ( to the nearest tenth )
Answer:
We are going to use Cosine [tex]\frac{adjacent}{Hypotenuse}[/tex]
[tex]\frac{45}{52}[/tex]
