evaluate 4^3 / 4^5
When dividing powers that have the same base, subtract the exponents.
So 4³/4⁵ is the same as 4³ ⁻ ⁵ or 4⁻².
When we have a base taken to a negative exponent,
it means the same thing as 1 over the base to the positive exponent.
In other words, we can rewrite 4⁻² as 1/4² or 1/16.

What is the area of the polygon given below?
A. 55 square units
B. 186 square units
C. 131 square units
D. 66 square units
Answer:
○ B. [tex]\displaystyle 186\:square\:units[/tex]
Explanation:
All edges conjoin to form right angles, therefore you have these:
[tex]\displaystyle \boxed{186} \hookrightarrow 121 + 30 + 35 \Rightarrow 11^2 + 5 \times 6 + 5 \times 7[/tex]
OR
[tex]\displaystyle \boxed{186} \hookrightarrow 120 + 66 \Rightarrow 24 \times 5 + 6 \times 11[/tex]

Find the indicated limit, if it exists.
Answer:
The limit is 1.
Step-by-step explanation:
In this kind of problem, we can use the left and right-hand limit method.
Basically, we need to find the limit by the left side and then by the right side. If both of them are equal the limit does exist if not the limit does not exist.
Left hand
[tex]lim_{-8^{-}}(f(x))=lim_{-8^{-}}(x+9)=-8+9=1[/tex]
Right hand
[tex]lim_{-8^{+}}(f(x))=lim_{-8^{+}}(-7-x)=-7-(-8)=1[/tex]
As we see, both limits are the same, so the limit is equal to 1.
I hope it helps you!

Answer:
m>z=85
x = 15!
Step-by-step explanation:
85=z because they are opposite eachother and the two lines intersect.
85*2=170, so we have 170 degrees for the two angles we know the measure of. Now, we need to find the remaining angles.
360-17=190. There is 190 degrees that need to be solved still.
190/2 is 95. Each angle remaining is 95 degrees.
8x-25=95
+25
8x = 120
/8
x=15
If you failed a math test, what are 2 things that you can do to prevent your careless errors?
Answer:
1) use a calculator
2) use desmos which is an online graphing calculator (trust me it will help you)
3) Do lots of practice (I know that you probably don't like to practice, but if you practice then you will prevent lots of careless errors because you will have more experience)
4) Pay attention to your teacher
5) When taking a test, try to avoid all distractions and focus on your test.
Answer:
For me, it really helps to go back and see what i got wrong, check where i made the mistake and solve it again. I think you need to know the basic concept before moving on since math builds on itself. If you have a teacher i think it would really help if you talk to them too, they may have some good tips to help you :)

Which angle measure must equal 52°?
A. а
в. Ь
с. с
D. d
Е. е
Answer:
Option C will be your answer
Step-by-step explanation:
Angle C will be equal to 52 by vertical angle theorem
hope it helps you
have a great day !!
Angle c is the vertical opposite angle with 52° so it will have a measure of 52° thus option (C) is correct.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.
Two opposite angle made by two intersecting lines is said to be vertically opposite angle so the angle opposite to 52° is c so, ∠c = 52°.
Hence " Angle c has a measure of 52° since it is the vertical opposite angle with 52°".

Heather is considering purchasing an item that costs $17. The sales tax in Heather's area is set at 7.5%. What is the total purchase price that leather would be charged on this purchase? Round your answer to the nearest cent, if necessary.
Answer:
$18.28
Step-by-step explanation:
To get the answer all I did was take 7.5% of 17 which is 1.275
I then rounded 1.275 to 1.28. When you round up the number after the 7 has to be 5 or above. Seeing as the number was 5 we rounded it up to 1.28.
Then I took $17+$1.28= $18.28.
I hope this helps!!!
Triangle A'B'C'is the result of reflecting triangle ABC across the line l
Choose all answers that apply
a. BC and B'C' are both perpendicular to the y-axis
b. <B and <B' have the same measures
c. The perimeters of ABC and A'B'C' are the same
D. None of the above
9514 1404 393
Answer:
b, c
Step-by-step explanation:
Reflection across a line is a "rigid" transformation, so linear measures and angle measures remain unchanged. (b and c are true statements)
Reflection across a line skew to the y-axis will mean that any segment originally perpendicular to the y-axis will not be after the reflection. ('a' is not a true statement)

Which expression is equal to (6x−4)(3x−1)?
18x2+18x−4
9x2−6x−5
18x2−18x+4
18x2−18x−5
The equivalent of the given expression (6x−4)(3x−1) is 18x² - 18x + 4.
Hence, option C)18x² - 18x + 4 is the correct answer.
What is the equivalent of the given expression?FOIL Method is simply a method used to multiply binomials where one multiply first terms and then the outside terms, next, inside terms and then last terms, and finally, combine like terms.
Given the expression in the question;
(6x−4)(3x−1)
Expand using FOIL method, apply the distributive property.
(6x−4)(3x−1)
6x( 3x − 1 ) - 4( 3x − 1 )
(6x × 3x ) + ( 6x × -1 ) - ( 4 × 3x ) - ( 4 × -1 )
Simplify
(6x × 3x ) + ( 6x × -1 ) - ( 4 × 3x ) - ( 4 × -1 )
18x² + (-6x) - (12x) - (-4)
Remove parenthesis and combine like terms
18x² - 6x - 12x + 4
18x² - 18x + 4
The equivalent of the given expression (6x−4)(3x−1) is 18x² - 18x + 4.
Hence, option C)18x² - 18x + 4 is the correct answer.

What is the value of X and Y?
9514 1404 393
Answer:
x = 20
y = 70
Step-by-step explanation:
The exterior angle marked 40° is the sum of the remote interior angles in the isosceles triangle at lower right, both of which are x°.
40° = 2x°
x = 20 . . . . . divide by 2°
The angle marked y° is the complement of the one marked x°.
y = 90 -x = 90 -20
y = 70

Umaloja vendeu 2.800 calçado no mês passado, neste mês vendeu10% a mais. Quantos calçados foram ven- didos neste mês
Answer:
3.080 calzados.
Step-by-step explanation:
Dado que Umaloja vendió 2.800 calzados el mes pasado, y este mes vendió un 10% más, para determinar cuantos calzados fueron vendidos este mes se debe realizar el siguiente cálculo:
2800 + ((2.800 x 10) / 100) = X
2.800 + (28.000 / 100) = X
2.800 + 280 = X
3.080 = X
Así, este mes Umaloja vendió 3.080 calzados.
