Evaluate (2/3)^2 Give your answer as a fraction in its simplest form.
i wasn't taught this ever
Answer: Most likely 0.44444 (The 4 is repeating.)
Step-by-step explanation:
Because first since its in parenthesis, you would do 2/3 which is 0.6666 repeating. Then you do that to the power of 2 which will give you 0.4 repeating!
Hope this works! If not, I apologize.
Use the diagram and the given angle measure to find the other three measures.
$m\angle1=143\degree$ Line segments drawn on a pair of scissors. Two line segments intersect creating obtuse vertical angles 1 and 3 and acute vertical angles 2 and 4.
$m\angle2=$
a
$\degree$
$m\angle3=$
$\degree$
$m\angle4=$
$\degree$
The three measures of the angle are,
Angle 2 = 37°
Angle 3 = 153°
Angle 4 = 37°
When two straight lines or rays intersect at a single endpoint, an angle is created. The intersection of two points is where an angle's vertex is located. The Latin word "angulus," which means "corner," is where the term "angle" originates. The building's corner provided protection, whether it was a projecting portion or a partially covered area. 2a: Dihedral angle and the figure created by two lines that originate from the same point.
I guess refers to two intersecting angle which form 4 angles.
Angles 1 and 2 are supplementary angles whose sum is 180°.
Angle 1 + Angle 2 = 180°
143° + angle 2 = 180°
Angle 2 = 180° - 143°
Angle 2 = 37°
Angles 1 and 3 are vertical angles, therefore treat them as such.
Therefore, it is easy to find their measures because vertical angles are congruent in measures.

A -4 nc point charge is located at -3 m along the x-axis. what is the electric potential at the origin?
The electric potential at the origin is 11.9834 ×[tex]10^{9}[/tex] .
What is electric potential?V = k (q/r)
V = 8.98755 × [tex]10^{9}[/tex] ×(-4/3)
V= 11.9834 ×[tex]10^{9}[/tex] is the the electric potential at the origin.
The effort required to transfer a unit charge against an electric field from a reference point to a specified spot.
Electric potential difference is the potential created when a charge is moved from one point to another within the field itself, whereas electric potential is the effort done per unit charge to transport the charge from infinity to a point in the electric field.
The amount of work required to move a unit positive charge from infinity to a particular point in an electric field is called the electric potential.

Write an explicit and a recursive formula for each sequence. 0,6,12,18,24, . . . . . .
an=a1+d(n−1) is the explicit and a recursive formula for each sequence .
What is sequence?An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence. For instance, the common difference in the arithmetic series 3, 9, 15, 21, and 27 is 6.
Arithmetic sequences are sequences containing these patterns. The distance between succeeding terms in an arithmetic series is always the same. The difference between consecutive words is always two, hence the sequence 3, 5, 7, 9... is arithmetic.
An explicit formula that states a = d (n - 1) + c, where d is the common difference between succeeding words, and c = a1, can be used to establish an arithmetic sequence.

what is domain and range?
The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.How are domain and range determined?
In order to identify the values of the independent variable x and acquire the domain, we simply solve the equation y = f(x). Simply put, x=g(y) will calculate the function's range after we identify g's domain (y).relation. (3,-2),(4,4),(0,-2),(4,1),(3,2)

Sean is thinking of a 3 digit number. the digit in the hundreds place is 1 more than the digit in the ones place. the value of the digit in the ones place is 25 less than the value of the digit in the tens place. what number is sean thinking of?
635 is the 3 digit number Sean is thinking of.
What is a digit?A digit is one of the elements of a set that makes up a numeration system. Thus, in a certain context, a digit is a number. The digits in the decimal (base-10) Arabic numbering system are the constituents in the set 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
Let a, b , c the digits of hundreds place, tens place and ones places.
Let the digit in the tens place be x, thus b = x
The digit in ones place is 25 less than the value of the digit in the tens place
c = x - 25
And finally, he digit in the hundreds place is 1 more than the digit in the ones place
a = (x - 25) +1
If a, b , c are digits of there respective places the the value of their digits are
a(100), b(10) c(1)
Now, b can be any no. which is more than 25 so as to make positive ones place, lets say 30
b = 30 = x
Thus x = 3, so
a = ( x - 25) +1
= ( 30 - 25) +1
= 6
c = 30 - 25
= 5
Thus, 635 is the 3 digit number Sean is thinking

A model plane would be 57.7 feet high.
In this question,
A model airplane takes off at an angle of elevation of 30°C
We need to find how much the plane will be high after traveling 100 feet horizontally.
Consider the following diagram.
Let angle ACB is the angle of elevation.
∠ACB = 30°
the horizontal distance CB = 100 feet
We need to find the distance AB.
Consider tangent of angle ACB.
⇒ tan(30) = AB / BC
⇒ 0.577 = AB / 100
⇒ AB = 0.577 × 100
⇒ AB = 57.7 feet
Therefore, a model plane would be 57.7 feet high.

much money did Lang have in his bank
account before his first withdrawal?
Land withdrew money in the form of an geometric series and he had $96 in his account in January.
A geometric series in mathematics is made up of an unlimited number of terms with a fixed ratio between them.
Each term is connected to the previous term by a simple ratio.
if the first term of an Geometric series be a, and the common ratio r then the second term is ar, third term is ar² and so on.
the nth term of a Geometric series is calculated by
[tex]a_n=ar^{n-1}[/tex]
Now here we know that the final term of the Geometric series is $1.50.
So each month Lang withdrew half of his money.
So the common ratio of each terms is [tex]\frac{1}{2}[/tex].
Number of months=6(n=7)
Now we have to find the initial term of the Geometric series.
We know that [tex]a_n=ar^{n-1}\\[/tex]
Given n=7 and r=1/2 and aₙ=1.5
Substituting the values we get:
[tex]1.5=a\times(\frac{1}{2})^{7-1} \\or, 1.5=a \times (\frac{1}{2} )^6\\or, 1.5=a\times \frac{1}{64} \\or,a=96[/tex]

There was a base fee of $17.95 and there was an additional charge of 92 cents for each mile driven. Shen had to pay $173.43 when he returned the truck. For how many miles did he drive the truck?
Th number of miles driven by truck is 169.
What is defined as the unitary method?The unitary method is an approach that involves determining the value of a single unit and then calculating the value of the necessary number of units based on that value.The unitary method's formula is to identify the value of a single unit and afterwards multiply that value by the number of units to get the required value.For the given question:
The base fee of the drive = $17.95.
The additional charges are 92 cents for each mile driven.
The additional charges = $0.92
Let 'x' be the miles driven by the truck.
Thus, the total additional charges for the drive of x miles will be: 0.92x.
So, the total charge for truck drive is;
The total charge are given as $173.43.
Total charge = base charge + additional charge
$173.43 = $17.95 + 0.92x
0.92x = $173.43 - $17.95
0.92x = 155.53
x = 169.05
x = 169 miles.
Thus, the total number of miles driven by the truck are 169 miles.
