A trough at the end of a gutter spout is meant to direct water away from a house. The homeowner makes the trough from a rectangular piece of aluminum that is 22IN long and 4 IN wide. He makes a fold along the two long sides a distance of inches from the edge.
(a) Write a function to represent the volume in terms of x
(b) What value of x will maximize the volume of water that can be carried by the gutter?
(c) What is the maximum volume?
a) The function that represents the volume of the trough in terms of x is V(x) = 88x - 8x².
b) x = 5.5 inches.
c) The maximum volume is 0 cubic inches.
What is a function?A function is a mathematical concept that describes a relationship between two sets of values, typically represented as variables. A function maps each element of the first set, called the domain, to a unique element of the second set, called the range. In other words, a function assigns a single output value to each input value.
For example, consider the function f(x) = x². The domain of this function is all real numbers, and the range is all non-negative real numbers. For each value of x, the function f(x) returns the square of that value.
According to the given information(a) Let x be the distance in inches that the homeowner makes the fold along the two long sides of the rectangular piece of aluminum. Then, the height of the resulting trough will be x inches, and the length of the trough will be 22 - 2x inches (since the fold reduces the length by 2x inches). The width of the trough will still be 4 inches.
The volume of the trough can be found by multiplying its length, width, and height:
V(x) = (22 - 2x) * 4 * x
V(x) = 88x - 8x²
So, the function that represents the volume of the trough in terms of x is V(x) = 88x - 8x².
(b) To find the value of x that maximizes the volume of water that can be carried by the gutter, we need to find the maximum point of the function V(x). We can do this by taking the derivative of V(x) with respect to x, setting it equal to zero, and solving for x:
V'(x) = 88 - 16x
88 - 16x = 0
16x = 88
x = 5.5
Therefore, the value of x that maximizes the volume of water that can be carried by the gutter is x = 5.5 inches.
(c) To find the maximum volume, we substitute x = 5.5 into the function V(x):
V(5.5) = 88(5.5) - 8(5.5)^2
V(5.5) = 242 - 242
V(5.5) = 0
Therefore, the maximum volume of water that can be carried by the gutter is 0 cubic inches.

Our negative number means that the government owes you $413.75. We would have to pay the government money if it weren't a negative number.
What is tax?In order to pay for general government services, goods, and activities, local, state, and federal governments must collect mandated payments or charges from citizens and corporations.
Since ancient times, paying taxes to governments or officials has been a fundamental aspect of civilization.
So, to address this issue, utilize the Single column.
You must first calculate her taxes before deducting the tax credit.
She earns $17,000 in taxable income. She now falls into the 15% category.
The amount owed on the first 9275 dollars that are subject to the tax must first be determined.
.10 * 9275 = 927.50
The remainder of her debt, which is in the 15% range, must then be collected.
.15 * (17000 - 9275) = 1158.75
Add up all of our taxes on the money, then deduct our tax credit of $2500.
(927.50 + 1158.75) - 2500
(2086.25) - 2500 = -413.75

How many solutions does this equation have 5(2x − 3) = 15
Answer: one solution x=3
Step-by-step explanation:
this problem is very simple, we need to figure out out what number(x) when multiplied by 2, and then you minus 3 (2x-3)
we need to then multiply this number by 5 to get 15, so 5x3 is what we need to find, so then we need to have the number 6 as 2x, or 3 as x.
so we end up with equation 5(2*3-3) or, 5(6-3), which equals 5*3= 15.

In the sequence 4, 7, 12, 19 write the next two terms
Answer:
Step-by-step explanation:
To find the next two terms in the sequence, we need to look for a pattern or rule that generates the sequence.
Looking at the differences between successive terms, we can see that they are increasing by 1, 2, and 3 respectively:
7 - 4 = 3
12 - 7 = 5
19 - 12 = 7
So, the next difference should be 9, and we can add it to the last term in the sequence to get the next term:
19 + 9 = 28
Similarly, we can add the next difference of 11 to get the term after that:
28 + 11 = 39
Therefore, the next two terms in the sequence are 28 and 39.
So, the complete sequence is: 4, 7, 12, 19, 28, 39.

The area of a regular decagon with a radius of its circumscribed circle equal to 9 is approximately 119.1 to the nearest tenth
How do you calculate for the area of a regular decagonTo calculate the area of a regular decagon with a radius of its circumscribed circle equal to 9, we need to first find the length of its sides.
For a regular decagon, the relationship between the radius of its circumscribed circle (R) and the length of its sides (a) is:
a = R × sqrt(2 - 2×cos(360/10))
Simplifying this equation, we get:
a = R × sqrt(2 - 2×cos(36))
a ≈ 5.5629
Now that we have the length of the sides, we can use the formula for the area of a regular decagon:
A = (5/4) × a² × (sqrt(5 + 2 × sqrt(5)))
A = (5/4) × (5.5629)² × (sqrt(5 + 2 × sqrt(5)))
A = 154.7293/4 ×

Caleb has a job that pays $11.15 per hour for a 40-hour work week. He is paid time and a half for every hour over 40 that he works in a week. What will his gross pay be for a week in which he works 46 hours?
Answer:
Caleb's regular pay for 40 hours of work is:
$11.15/hour × 40 hours = $446
For the 6 hours of overtime, he is paid time and a half, which is:
$11.15/hour × 1.5 = $16.725/hour
So for the 6 hours of overtime, his pay is:
$16.725/hour × 6 hours = $100.35
His total gross pay for the week is the sum of his regular pay and his overtime pay:
$446 + $100.35 = $546.35
Therefore, Caleb's gross pay for a week in which he works 46 hours is $546.35.

For the cost of fabric used, we have:
Cost of fabric used = 2.5 × $4.50
Cost of fabric used = $11.25
Profit = selling price - cost
Profit = $17.50 - $11.25
Profit = $6.25.

On a piece of paper, graph f(x)=(). Using the graph, decide which one of
10
these statements is true.
9
A. The range of f(x) is y>.
10
B. It is always increasing.
C. The y-intercept is (0, 1).
OD. The domain of f(x) is x > 0.
Where the function f(x) = (9/10)ˣ is given, all the functions are correct with the EXCEPTION of option D.
How is this so ?A. The range of f(x) is y > 0 since any positive number raised to any power is positive.
Therefore, f(x) = (9/10)ˣ > 0.
B. Since the base of the exponential function, 9/10, is less than 1, f(x) is a decreasing function. Therefore, it is not always increasing
C. To find the y- i ntercept of f(x ), we substitute x=0 into the equation:
f(0) = (9/10)⁰ = 1.
Therefore, the y- intercept is ( 0, 1).
D. The domain of f(x) is x ≥ 0, not x > 0. The function is defined for all non negative real numbers since any non-negative number can be raised to any power.

Step-by-step explanation:
Assume that when human resource managers are randomly selected, 42% say job applicants should follow up within two weeks. If 5 human resource managers are randomly selected, find the probability that at least 2 of them say job applicants should follow up within two weeks.
Which statement is true?
3 x (4 + 2) − 5 = 5 x (6 + 3) ÷ 3
3 x (one-half x 8) ÷ 6 = 8 ÷ (one-fourth x 16) + 2
6 + (2.5 x 5) − 3.5 = 14 ÷ (3.5 x 2) + 8
5 x (4 + 9 ÷ 3) = 3 x (3 + 5) + 11
The last statement 5 x (4 + 9 ÷ 3) = 3 x (3 + 5) + 11 is true.
All other statements are false.
What is PEDMAS rule ?The PEDMAS rule is a rule in mathematics which tells us how to evaluate an arithmetic expression. By an arithmetic expression we mean expressions like 5 x (6 + 3) ÷ 3 and 14 ÷ (3.5 x 2) + 8.
Each such expression has a value. The PEDMAS rule gives us a sequence of steps, following which we can correctly find the value of an arithmetic expression.
The letters in the word PEDMAS stand for P : Parenthesis,
E : Exponentiation,
D: Division,
M : Multiplication,
A : Addition,
S : Subtraction.
According to this rule we must first
1. Evaluate any parenthesis, that is any expression inside any parenthesis 2. Then any exponential and nth roots.
3. Then evaluate any divisions.
4. Then any multiplication.
5. Then any addition.
6. Finally any subtraction.
This rule is also called the BODMAS rule.
The first two letters stand for Bracket and OF.
In the given expressions:
3 x (4 + 2) − 5 = 3 x 6 - 5 = 18 - 5 = 13,
while 5 x (6 + 3) ÷ 3 = 5 x 9 ÷ 3 = 5 x 3 = 153 x (one-half x 8) ÷ 6 = 3 x 4 ÷ 6 = 2,
while 8 ÷ (one-fourth x 16) + 2 = 8 ÷ 4 + 2 = 2 + 2 = 46 + (2.5 x 5) − 3.5 = 6 + 12.5 -3.5 = 15,
while 14 ÷ (3.5 x 2) + 8 = 14 ÷ 7 + 8 = 2 + 8 = 105 x (4 + 9 ÷ 3) = 5 x (4 + 3) = 5 x 7 = 35,
while 3 x (3 + 5) + 11 = 3 x 8 + 11 = 24 + 11 = 35

Answer: d eez
Step-by-step explanation:
make a number line a ns mark all the points that represent the following values of x.
x≤-2 and x<-5
All the points less than -5 will be marked on the number line.
To represent the values of x where x ≤ -2 and x < -5 on a number line, we start by marking a point at -2 and shading everything to the left of it since x is less than or equal to -2. Next, we add another shading to the left of -5 since x is also less than -5. We then mark an open circle at -5 since x is not equal to -5.
Our number line would look like this as image attached below.
The shaded region to the left of -5 represents all values of x that are less than -5. The shaded region between -5 and -2 represents all values of x that are between -5 and -2, including -5 and -2. The open circle at -5 indicates that x cannot equal -5, but can be any other value less than -5.
