Answer:
After 11 weeks, Darnell′s savings account will have a total of $8,360.
Step-by-step explanation:
The data provided is as follows:
n: 1 2 3 4
f (n): 260 360 460 560
Consider the data for f (n).
The series f (n) follows an arithmetic sequence with a common difference of 100 and first term as 260.
The nth term of an arithmetic sequence is:
[tex]a_{n}=\frac{n}{2}[2a+(n-1)d][/tex]
Compute the value of f (11) as follows:
[tex]f(11)=\frac{11}{2}[(2\times260)+(11-1)\times 100][/tex]
[tex]=5.5\times[520+1000]\\\\=5.5\times 1520\\\\=8360[/tex]
Thus, after 11 weeks, Darnell′s savings account will have a total of $8,360.

-22
Answer:
-22
Step-by-step explanation:
When you multiply a positive and negative number together, it becomes negative.
Multiplication is repetitive addition.
11(-2) = -11 + -11 = -22

What is the value of h(−2) when h(x)=3x+1?
Enter your answer in the box.
h(−2)=
Answer:
-5
Step-by-step explanation:
The answer is -5 because we have -2 as x. The function is h(x)=3x+1. 3 times -2=-6. When we add 1 to the result, we have -5 as the answer. Hope it helps!
The value of h(−2) when h(x)=3x+1 is h(-2) = -5
From the question,
The given function is h(x)=3x+1
To determine the value of h(-2), we will put x = -2 and evaluate
From
h(x)=3x+1
h(-2) becomes
h(-2)=3(-2) + 1
h(-2) = (3× -2) + 1
h(-2) = (-6) + 1
h(-2) = -6 + 1
h(-2) = -5
Hence, the value of h(−2) when h(x)=3x+1 is h(-2) = -5

Two laboratory technicians are running product quality tests. One technician takes 6 minutes less than the
other. What equation would give the amount of time, t, it would take to run the tests if the technicians work
together to split the work on the different tests?
Answer:
The time it will take will be ;
t = (2x -6)/(x^2-6x)
Where x is the amount of time
in minutes taken by the technician who is slower
Step-by-step explanation:
We want to write the time it would take to run the tests if the technicians work together.
Let the time taken by the first technician be x minutes
The time that would. taken by the second is 6 minutes less which is (x -6) minutes
So if they work together, how long will it take?
That would be ;
t = 1/x + 1/(x-6)
t = (x + x -6)/(x(x-6))
t = (2x -6)/(x^2 -6x)
The time it will take if they both work together is ;
t = (2x -6)/(x^2-6x)
where x minutes is the amount of time taken by the technician who is slower of the two
A line with a positive slope is parallel to one of the lines shown. What is its slope? Use the graph shown below.
The slope is 0.75 as 3/4 = 0.75
Answer:
Step-by-step explanation:
Only the blue line has a positive slope. So the new line is parallel to the blue line.
Clearly, the blue line goes through the point (0, 3) (this is the y-intercept). Follow this blue line upward and to the right until it intersects the horizontal line at the top of the diagram. We must estimate the x-value of this point of intersection. A good approximation would be 5 1/3.
Now estimate the slope of the blue line. Starting at (0, 3), we move 5 1/3 units to the right (this is the "change in x," or "run") We end up at (5 1/3, 3).
Now, from the horizontal line y = 3 upward to the horizontal line at the very top of the graph, is 5 units. This is the "rise."
Thus, the approximate value of the slope here is
5 5 15
m = rise / run = ---------- = -------------- = ----------- = m
5 1/3 16/3 16

A rectangular prism is completely packed with 84 cubes of edge length fraction 1 over 3 inch, without any gap or overlap. Which of these best describes the volume of this rectangular prism?
Step-by-step explanation:
The volume of a cube is s^3 where s is the length of a side..
So If you have 84 cubes with sides of 1/3 in the total volume is:
v=84(1/3)^3 in^3
v=84/27 in^3
v=28/9 in^3
V=3.11 in^3 (to nearest hundredth of a cubic inch)

Determine the 50th term in the sequence defined by an = -11+ 5(n − 1).
The 'nth' term is a formula with 'n' in it which enables you to find any term of a sequence without having to go up from one term to the next. 'n' stands for the term number so to find the 50th term we would just substitute 50 in the formula in place of 'n'.

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

17,400 - 3000 = 14,400
Let x be the number of months.
300x = 14,400
Divide by 300.
x = 48
12 months = 1 year
4 years is the answer.
Answer:
4 years
Step-by-step explanation:
Equation: 300x + 3000 = 17400
Subtract 3000 from both sides;
300x = 14400
Divide both sides by 300;
x = 48 months
48 months = 4 years
