Lynne walks dogs every day to earn money. The fees she charges per month are 1 dog,$40;2 dogs,$37.25 each;3 dogs,$34.50 each;4 dogs,$31.75 each. A pet store wants her to walk 8 dogs if the pattern continues, how much will Lynne charge to walk each of the 8 dogs.
Answer:
The answer is $20.75
A dog: 40$
2: $37.25
3: $34.50
4: $31.75
5: $29
6: $26.25
7: $23.50
8: $ 20.75
Step-by-step explanation:
Minus $2.75 is the pattern
Answer:
$ 59.25
Step-by-step explanation:
The given rates form an AP (Arithmetic Progression).
Let the cost of walking 1 dog be taken as the first term
and,
cost of walking 2 dogs as second term,
we notice that the price per dog is decreasing by 2.75 $ each time the number of dogs is increasing by 1.
So, it's safe to say that
In the AP:
First term is $ 40
Common difference is $ 2.75
Finding the charge to walk each of the eight dogs is like finding the 8th term of the given Series.
Formula for n-th term of a depreciating AP in terms of common difference(d) and first term(a):
[tex] \boxed{ \mathsf{a _{n} = a - (n - 1)d}}[/tex]
[tex] \implies \mathsf{a _{8} = 40 - (8 - 1) \times 2.75}[/tex]
[tex] \implies \mathsf{a _{8} = 40 - 7 \times 2.75}[/tex]
[tex] \implies \mathsf{a _{8} = 40 - 19.25}[/tex]
[tex] \implies \mathsf{a _{8} = \underline{20.75}}[/tex]
Answer:Hence, the charge to walk each of the eight dogs is $ 20.75

solve for x PLS HELP QUICK I HAVE A FINAL TMRW AND I REALLY NEED TO KNOW HOW TO DO IT
Answer:
x = -9/2
Step-by-step explanation:
64 = 2^6
if you have the same base, you can set the exponents equal and solve for x.
-2x-3 = 6
-2x = 9
x = -9/2
good luck on your final! you got this!
Step-by-step explanation:
[tex] {2}^{ - 2x - 3} = 64[/tex]
first, get 64 to a base of 2
[tex] {2}^{ - 2x - 3} = {2}^{6} [/tex]
now we can drop the bases
[tex] - 2x - 3 = 6[/tex]
And now we can solve it like any other equation
[tex] - 2x = 6 + 3[/tex]
[tex] - 2x = 9[/tex]

what does i^739 equal? explain how you found your answer.
========================================================
Explanation:
i = sqrt(-1)
Lets list out the first few powers of i
i^0 = 1i^1 = ii^2 = -1i^3 = i*i^2 = i*(-1) = -ii^4 = (i^2)^2 = (-1)^2 = 1By the time we reach the fourth power, we repeat the cycle over again (since i^0 is also equal to 1). The cycle is of length 4, which means we'll divide the exponent over 4 to find the remainder. Ignore the quotient. That remainder will determine if we go for i^0, i^1, i^2 or i^3.
For example, i^5 = i^1 because 5/4 leads to a remainder 1.
Another example: i^6 = i^2 since 6/4 = 1 remainder 2
Again, we only care about the remainder to find out which bin we land on.
-------------
Turning to the question your teacher gave you, we have,
739/4 = 184 remainder 3
So i^739 = i^3 = -i
-i is the final answer--------------
Side notes:
if i^a = i^b, then a-b is a multiple of 4Recall that the divisibility by 4 trick involves looking at the last two digits of the number. So i^739 is identical to i^39.Help me with this I can’t ;c

There are 3 times as many books in the town library as there are in the school library. The town library has 2,676 books.
How many books are in the school library?
Answer: First we know the Town Library has 3 times as many books as there are in the School Library. The Town Library has 2,676 books.
Divide 2,676 by 3. 2676÷3= 892
So your answer is: 892 books.
Hope I helped. :)
The number of books in the library will be 892.
Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that there are 3 times as many books in the town library as there are in the school library. The town library has 2,676 books.
The number of books will be calculated as,

c. 118,098
d. -19,683
Answer:
b. [tex]a_{12}=-177147[/tex]
Step-by-step explanation:
This is a geometric sequence:
[tex]a_n=a_1x^{n-1}[/tex]
where n is the index in the sequence and x is the common scale factor.
In the given sequence here, the common factor is 3:

The simplification of the given expression gives the value 9.
What is simplification?Simplification is defined as a process in mathematics to operate and interpret an expression to make the expression simpler.
This can be done using various results or the basic operations of numbers.
Given expression is 3⁻⁶ × (3⁴ / 3⁰)².
We have to use product rule and quotient rule of exponents to simplify this.
We know that,
xᵃ × xᵇ = xᵃ⁺ᵇ
xᵃ / xᵇ = xᵃ⁻ᵇ
Also, (xᵃ)ᵇ = xᵃᵇ
3⁴ / 3⁰ = 3⁴⁻⁰ = 3⁴
Substituting,
3⁻⁶ × (3⁴ / 3⁰)² = 3⁻⁶ × (3⁴)²
= 3⁻⁶ × 3⁸
= 3⁻⁶⁺⁸
= 3²
= 9
