Answer:
Thus, the eleventh term is -25.
Step-by-step explanation:
Arithmetic Sequences
The arithmetic sequences are identified because any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.
The equation to calculate the nth term of an arithmetic sequence is:
[tex]a_n=a_1+(n-1)r[/tex]
Where
an = nth term
a1 = first term
r = common difference
n = number of the term
We are given the sequence:
5,2,-1,-4,...
We can directly find the common difference by subtracting two successive terms:
r = 2 - 5 = -3
The same result is obtained by subtracting any pair of successive terms.
The first term is a1 = 5. The general equation is:
[tex]a_n=5-3(n-1)[/tex]
[tex]a_n=5-3n+3[/tex]
[tex]a_n=-3n+8[/tex]
We need to find which term is -25, thus:
-3n + 8 = -25
Subtracting 8:
-3n = -25 - 8 = -33
Dividing by -3:
n = -33 / (-3)
n = 11
Thus, the eleventh term is -25.

[tex]\huge\underline\mathfrak\blue{Answer:-}[/tex]
The demoin is all real numbers greater than 6
The domain of the function is "All real numbers greater than 6".
What are logarithmic functions?Any exponential function may be represented in logarithmic form because logarithmic functions are the inverses of exponential functions.
The given equation is h(x) = 4log2(x-6) + 1.
The domain is the set of values that can be inserted into a function.
Note that the logarithmic of a negative number is not defined, therefore, the expression inside the log, x-6, must be greater than 0.
x - 6 > 0
x > 6
Hence, the domain of the function is "All real numbers greater than 6".

A combination of 3 erasers and 5 pencils cost $7.55. A combination of 6 erasers and 12 pencils cost $17.40. How much is each pencil?
Answer:
9.85
Step-by-step explanation:
I subtract 17.40 and 7.55 to get 9.85 they just wanted to know how much the pencil cost not erasers.
The cost of each pencil is $1.15.
What is a system of equation?A system of equations is used when there are two variables, and you are given two pieces of information about how those variables are related.
Given that, A combination of 3 erasers and 5 pencils cost $7.55. A combination of 6 erasers and 12 pencils cost $17.40.
Let e represents eraser and p represents a pencil.
Establishing the equations,
3e+5p = 7.55
6e+12p = 17.40
Solving by elimination, we get,
p = 1.15
Hence, The cost of each pencil is $1.15.

The Pythagorean Theorem, given by the formula a^2+b^2=c^2, relates the three sides of a right triangle. Solve the formula for the positive value of a in terms of b and c.
Answer:
c=√a²b²
Step-by-step explanation:
The positive value of 'a' in terms of b and c will be [tex]a =\sqrt{b^2-c^2}[/tex].
What is the Pythagorean theorem?Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
It is given that the formula of the Pythagorean theorem for a right-angle triangle is, a² + b² = c².
The value of c is calculated as:-
a² + b² = c²
Reverse the equation to calculate a.
c² = a² + b²
Taking b² to the left side then the equation will become:-
a² = c² - b²
Taking square root on both sides of the equation.
[tex]\sqrt{a^2}=\sqrt{c^2-b^2[/tex]
[tex]a = \sqrt{c^2-b^2}[/tex]
Therefore, the positive value of 'a' in terms of b and c will be [tex]a =\sqrt{b^2-c^2}[/tex].

Answer:
$187
10b + 13c
Step-by-step explanation:
Payment for babysitting = $10 per hour
Payment for clearing tables = $13 per hour
How much money would Stella earn in a week in which she worked 7 hours babysitting and 9 hours clearing tables?
Total weekly payments = Payment for babysitting × number of hours + Payment for clearing tables × number of hours
= 10 × 7 + 13× 9
= 70 + 117
= $187
How much money would Stella
week in which she worked b hours babysitting and c hours clearing tables?
Total weekly payments = Payment for babysitting × number of hours + Payment for clearing tables × number of hours
= 10 × b + 13 × c
= 10b + 13c
A car went 64 miles on 2 gallons of gas in the morning, 16 miles on 1/2 gallon of gas at noon, and 32 miles on 1 gallon of gas at 5:00 PM. Is the amount of gas used proportional to the distance the car drove? Why or why not?
Answer:
Yes,
Step-by-step explanation:
You take 64 miles for 2 gallons and divide it by 2. And it leads up to 32 miles and 1 gallon. Now you divide that by 2 again and get 16 miles and 1/2 gallon. So, to check that you can take 16+16 and you get 32 and take 32+32 and you get 64.
The equation that models this relationship is y=2x. How many liters of water should Austin combine with 16 scoops of juice mix? Write your answer as a whole number or decimal.
Answer:
8 liters
Step-by-step explanation:
Given that:
y = 2x
where y is the number of scoops of juice mix, and x is the liters of water required.
To determine the liters of water required for 16 scoops of juice mix;
y = 16
So that,
16 = 2x
x = [tex]\frac{16}{2}[/tex]
= 8
x = 8 liters
Therefore, Austin would combine 8 liters of water to the 16 scoops of juice mix.
