Answer:
5.52 × 10^ 3
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Triangle ABC is dilated using the dilation rule D0.5(x, y) to form triangle A'B'C'. Point A is located at (10, 7.5), point B is located at (–5, 2), and point C is located at (0.5, –7).
Answer:
The coordinates of A' are [tex]A'(x,y) = (5, 3.75)[/tex].
The coordinates of B' are [tex]B'(x,y) = (-2.5, 1)[/tex].
The coordinates of C' are [tex]C'(x,y) = (0.25, -3.5)[/tex].
Step-by-step explanation:
The statement is incomplete, we present the complete statement below: Triangle ABC is dilated using the dilation rule [tex]D = 0.5\cdot (x,y)[/tex] to form triangle A’B’C’. Point A is located at [tex]A(x,y) = (10, 7.5)[/tex], point B is located at [tex]B(x,y) =(-5,2)[/tex], and point C is located at [tex]C(x,y) =(0.5,-7)[/tex]. What are the coordinates of A’? What are the coordinates of B’? What are the coordinates of C’?
We proceed to calcultate the coordinates of the triangle A'B'C' hereafter:
What are the coordinates of A'?
[tex]A'(x,y) = 0.5\cdot A(x,y)[/tex] (1)
[tex]A'(x,y) = 0.5\cdot (10, 7.5)[/tex]
[tex]A'(x,y) = (5, 3.75)[/tex]
The coordinates of A' are [tex]A'(x,y) = (5, 3.75)[/tex].
What are the coordinates of B'?
[tex]B'(x,y) = 0.5\cdot B(x,y)[/tex] (2)
[tex]B'(x,y) = 0.5\cdot (-5,2)[/tex]

Lydia has 400$ in her bank account. Each week she withdraws 10$ for spending money. She also uses 5$ each week to get credit on her apple account. Which inequality statement can be used to determine how many weeks it will take for her bank account balance to drop below 300$ ?
Answer:
400 - 15x < 300
Step-by-step explanation:
We are told that she has 400$ in her bank account.
Now, Each week she withdraws 10$ for spending money. She also uses 5$ each week to get credit on her apple account.
Total total withdrawal each week = 10 + 5 = $15
If number of weeks she has been withdrawing is x, then would have withdrawn $15x after x number of weeks.
Thus, amount left after x number of weeks is:
400 - 15x
We want to find the inequality statement can be used to determine how many weeks it will take for her bank account balance to drop below 300.
Thus;
400 - 15x < 300

You must scuba dive to the entrance of your room at Jules' Undersea Lodge in Key Largo, Florida. The diver is 1 foot deeper than 2/3 of the elevation of the entrance. The diver is -15 feet in the water. What is the elevation of the entrance?
Answer:
The answer is -21
Step-by-step explanation:
The elevation of the entrance of your room at Jules' Undersea Lodge is equal to -21 feet.
What do you mean by algebraic expressions ?
Algebraic expression is an equation which consists of variables and the arithmetic operations such as division , multiplication , etc.
It is given that , diver is 1 foot deeper than 2/3 of the elevation of the entrance. And the depth of diver is equal to -15 feet.
So , the diver is at depth under water = -15 feet
Let's assume that elevation of entrance is at x foot.
So , the algebraic expression representing the depth of diver is given by :
[tex]\frac{2}{3}[/tex] × x - 1 = -15
Solving for the value of x or the elevation of entrance we get :
[tex]\frac{2}{3}[/tex] x = -15 + 1
[tex]\frac{2}{3}[/tex] x = -14
2x = -14 × 3
x = -42 / 2
x = -21 feet
Thus , the elevation of the entrance of your room at Jules' Undersea Lodge is equal to -21 feet.

Exit Ticket: 1-4 Waves
In the following diagram the waves move from left to right and then stop. The motion of the wave will continue down the
rope after 2 seconds. Type in your answers.
0.4m
Time (sec): 2
a) What is the amplitude of the waves? 5 pts
b) What is the wavelength of the waves? 5 pts
c) How many waves are generated in two seconds? 10 pts
d) What is the frequency of the waves? 10 pts
e) What is the period of the wave? 10 pts
Answer:
a) 0.4m
b)2m
c)2
d)1 s^-1
e) 1 s
Step-by-step explanation:
a) The amplitude of the wave is the highest vertical displacement
with respect to this question, this is 0.4m
b) The wavelength of the wave is simply the distance between two crest or troughs
In this question, this is 2m
c) The number of waves generated is 2
d) Frequency of the waves is the number of waves generated per second
if 2 waves are generated in 2 seconds
The number of waves in a second is 2/2 = 1
So the frequency is 1 s^-1
e) Period is 1/frequency
= 1/1 = 1 second

Step-by-step explanation:
A triangle's angles are always 180° total degrees.
The given triangle has the three little marks showing that the lengths are the same, so this means that the angles are also congruent. That means that the triangle is an equilateral triangle.
Set an equation where the given angle of F represents every angle and whose sum is 180°:
[tex](30t+20)+(30t+20)+(30t+20)=180\\\\3(30t+20)=180[/tex]
Solve for t. Use the distributive property:
[tex]90t+60=180[/tex]
Work to isolate the variable. Use inverse operations to cancel out the 60. Subtract 60 from both sides:
[tex]90t+60-60=180-60\\\\90t=120[/tex]
Use inverse operations to isolate t. Divide both sides by 90:
[tex]\frac{90t}{90} =\frac{120}{90} \\\\t=\frac{4}{3}[/tex]
The value of t is [tex]\frac{4}{3}[/tex].

So basically you can determine which of them are functions by using the vertical line test. If you can draw any vertical line that intersects more than one point of the relationship, then it is not a function.
