Answer:
(B) The exponents should be subtracted by the quotient rule of exponents
Step-by-step explanation:
Let's examine how this was solved.
[tex](\frac{4^2 4^3}{4^{-5}})^2[/tex]
He first rose everything in the parentheses to the second power, which is just multiplying all the exponents by 2. This is correct.
[tex]\frac{4^4 4^6}{4^{-10}}[/tex]
He then combined the numerator exponents. Exponent rules say that [tex]a^b \cdot a^c = a^b+c[/tex], so he should have ended up with [tex]4^{10}[/tex], which he did. This is correct.
[tex]\frac{4^{10}}{4^{-10}}[/tex]
Now, what he did in the final step is wrong. He added the exponents. However, exponent rules tell us that when we have [tex]\frac{a^b}{a^c}[/tex], it equals [tex]a^{b-c}[/tex].
[tex]10 - (-10) = 10+10 = 20[/tex]
So the final answer should have been [tex]4^{20}[/tex]

Which set of side lengths represents a triangle with 3 lines of reflectional symmetry?
3, 4, 5
3, 6, 9
5, 5, 5
5, 10, 5
Answer:
5, 5, 5
Step-by-step explanation:
i saw it on quizlet
The set of side length that represents a triangle with 3 lines of reflectional symmetry is 5,5,5
Reflectional symmetry is a line that divides a triangle into halves. The halves the triangle are divided into are a reflection of each other.
A triangle is a shape that has three sides with three angles which sum up to 180 degrees.
Types of triangles :
Equilateral triangle : the three sides of the triangle have an equal length. It has three lines of reflectional symmetry Right-angled triangle : the square of the longest side is equal to the sum of the square of the other two sides Scalene triangle : all the three sides of the triangle have different lengths. It has no line of reflectional symmetry. Isosceles triangle ; it has two sides that have an equal length. It has one line of reflectional symmetryTo learn more about reflectional symmetry, please check: https://brainly.com/question/1593820?referrer=searchResults

IF YOU HELP WILL MAKE BRAINLYIST!!!!!!!!
Answer:
In geometry, a polygon is a plane figure that is described by a finite number of straight line segments connected to form a closed polygonal chain or polygonal circuit. The solid plane region, the bounding circuit, or the two together, may be called a polygon.
The segments of a polygonal circuit are called its edges or sides, and the points where two edges meet are the polygon's vertices(singular: vertex) or corners.
So, if a shape has points where two edges meet, it is indeed a polygon. Some examples include: Equilateral Triangles, Squares, Regular Pentagons, Regular Hexagons, Regular Heptagons, and Regular Octagons.

Answer: 740Please help ik its kinda esay but is dificlut for me
Answer:
see explanation
Step-by-step explanation:
For a relation to be a function each value of x on the domain can only map to one unique value of y in the range.
For the given point, we can see that
x = 1 → y = 4 and x = 1 → y = 1
This breaks the function rule, thus the set is not a function
Explanation:
The list of first numbers of the ordered pairs is ...
1, 3, 1, 9, 0.
There is a repeated value, 1, so the relation cannot be a function. Each domain value can only appear once in a relation that is a function.
Sally buys a large drink every day for a full year (365 days). Each drink costs $2.82. Sally always pays $3.00 and drops her change in the tip
jar.
Which is the amount Sally tips in a year?
Answer:
$65.70
Step-by-step explanation:
She would be giving 18 cents each day for 365 day so you multiply 18x365 which equals 6570 and that written in dollars is $65.70

what is 5/6 + 4/6 + 1/6?
Answer:
The answer would be 1 2/3.
Step-by-step explanation:
First: (Add)
5/6 + 4/6 + 1/6 = 10/6.
Leaving the denominator the same.
Next: (Breakdown)
6 can go into 10, 1 time. With 4 more left. Which is 1 4/6.
Then the numerator and denominator can be divided both by 2. Which equals 1 2/3.

Here is Triangle A. Lin created a scaled copy of Triangle A with an area of 72 square units. C. What is the length of bottom side of the scaled copy?
Answer:
The length of bottom side of the scaled copy is 12 u
Step-by-step explanation:
To solve this problem we have to know that to calculate the area of a triangle we use the following formula
a = area
b = base
h = height
a = b * h
In the triangle A the base and the height are equal to 3
b = h
Now that we know that b & h we can calculate the base of the scaled copy
72 u² = b * b
72 u² = (b)²
√(72 u²) = b
12 u = b
The length of bottom side of the scaled copy is 12 u

hope this helps!!!The proceeds from a car wash are directly proportional to the number of cars washed. The total after 9 cars was $180. How much can be raised if 60 cars
are washed?
60 cars washed?
Answer:
$1200
Step-by-step explanation:
180 divided by 9 is 20, so they earned $20 per car washed. They want to wash 60 cars, and if they wash 60 cars they would earn $1200. (60 x 20)
Answer:
$1200
Step-by-step explanation:
Our revenue is directly proportional to the number of cars. That means our revenue is increasing at a constant rate, and thus, we are getting the same amount of money per car. That means we can find out how much we get from washing 1 car.
[tex]\frac{180}{9} = 20[/tex]
$20 per car.
If we washed 60 cars, we'd earn 60 * $20:
[tex]60*20 = 1200[/tex]
Answer: $1200
