Step-by-step explanation:
Use Newton's method to find the absolute maximum value of the function
f(x) = 7x cos(x), 0 ≤ x ≤ ,
correct to six decimal places.
Answer:
Step-by-step explanation:
Newton's method is an iterative method for finding the roots of a function, which means that it can be used to find the values of x that make a function equal to zero. It can also be used to find the maximum or minimum values of a function, but to do so you will need to find the derivative of the function and use that to determine where the maximum or minimum values occur.
The derivative of the function f(x) = 7x cos(x) is f'(x) = 7 cos(x) - 7x sin(x), and you can use this to find the maximum value of the function. To do this, you would need to find the values of x that make the derivative equal to zero, since the maximum or minimum values of a function occur at the points where the derivative is equal to zero.
To find the values of x that make the derivative equal to zero, you can use Newton's method, which involves starting with an initial guess for the value of x, and then using the derivative to find a better approximation for the value of x. This process is repeated until the desired level of accuracy is reached.
In your case, you could start by making an initial guess for the value of x that makes the derivative equal to zero. For example, you could start with x = 0 and then use the derivative to find a better approximation. This process would involve calculating the derivative at the initial guess, and then using that value to find a better approximation for the value of x. This process would be repeated until the desired level of accuracy is reached.
Once you have found the values of x that make the derivative equal to zero, you can plug those values back into the original function to find the maximum value of the function. This will give you the absolute maximum value of the function f(x) = 7x cos(x), 0 ≤ x ≤ , correct to six decimal places.

Suppose that the functions g and h are defined for all real numbers X as follows.
g(x)=x+2
h(x)=3x-3
Write the expressions for (h-g)(x) and (h+g)(x) and evaluate (h.g)(1).
Fehmen
If the two functions be g(x) = x + 2 and h(x) = 3x - 3 then
(h - g)(x) = 2x - 5
(h + g)(x) = 4x - 1
(h . g)(1) = 3x² + 3x - 6
What is meant by expression ?A phrase is considered a mathematical expression if it contains at least two numbers or variables and one or more mathematical operations. Mathematicians can multiply, divide, add, or subtract. An expression is structured as follows: (Math Operator, Number/Variable, Math Operator) is an expression.
Mathematical expressions are built using the addition, subtraction, multiplication, and division operations.
Let the two functions be g(x) = x + 2 and h(x) = 3x - 3
(h - g)(x) = h(x) - g(x)
substitute the value expressions in the above equation, we get
= (3x - 3) - (x + 2)
= 2x - 5
(h + g)(x) = h(x) + g(x)
= (3x - 3) + (x + 2)
= 4x - 1
(h . g)(1) = h(1) . g(1)
= (3x - 3) . (x + 2)
= 3x² + 3x - 6

Mrs. Saunders bought a 19 pound turkey for Thanksgiving. The total cost of the turkey was $25.65. What was the cost of turkey per pound? Write an equation to represent the situation
The cost of turkey per pound is $1.35 and the equation which represents the situation is 19x - 25.65 = 0.
What is the linear equation?
An algebraic equation of the form y=mx+b is referred to as a linear equation. m is the slope, and b is the y-intercept, and all that is involved is a constant and a first-order (linear) term. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."
We have,
19 turkey pound
$25.65
the cost of turkey per pound?
so,
25.65 / 19 = 1.35
the cost of turkey per pound is $1.35.
The equation becomes:
let's take x = $1.35
19x - 25.65 = 0
Hence, the cost of turkey per pound is $1.35 and the equation which represents the situation is 19x - 25.65 = 0.

Divide the polynomials.
Your answer should be a polynomial.
x² - 36
x − 6
Answer:
the answer to the division problem is `1x + 6` (a polynomial).
Step-by-step explanation:
To divide polynomials, we use the long division method. Here's how we can divide x² - 36 by x - 6:
x² - 36 |
--------
x - 6
First, we divide the leading coefficient of the numerator (which is 1) by the leading coefficient of the denominator (which is 1).
We get 1 / 1 = 1 as the first coefficient of our quotient.
x² - 36 |
--------
x - 6
1
Then, we multiply the quotient by the denominator and subtract it from the numerator.
We get (1 * (x - 6)) = x - 6, and x² - 36 - (x - 6) = x² - x - 30.
x² - 36 |
--------
x - 6
1
x - 6
----------
x² - x - 30
We repeat the process, dividing the leading coefficient of the new numerator (which is 1) by the leading coefficient of the denominator (which is 1).
We get 1 / 1 = 1 as the next coefficient of our quotient.
x² - 36 |
--------
x - 6
1
x - 6
----------
x² - x - 30
1
We multiply the quotient by the denominator and subtract it from the numerator.
We get (1 * (x - 6)) = x - 6, and x² - x - 30 - (x - 6) = x² - 2x + 24.
x² - 36 |
--------
x - 6
1
x - 6
----------
x² - x - 30
1
x - 6
---------------
x² - 2x + 24
We repeat the process one more time, dividing the leading coefficient of the new numerator (which is 1) by the leading coefficient of the denominator (which is 1).
We get 1 / 1 = 1 as the next coefficient of our quotient.
x² - 36 |
--------
x - 6
1
x - 6
----------
x² - x - 30
1
x - 6
---------------
x² - 2x + 24
1
We multiply the quotient by the denominator and subtract it from the numerator.
We get (1 * (x - 6)) = x - 6, and x² - 2x + 24 - (x - 6) = x² - 3x + 18.
x² - 36 |
--------
x - 6
1
x - 6
----------
x² - x - 30
1
x - 6
---------------
x² - 2x + 24
1
x - 6
------------------
x² - 3x + 18
Since the degree of the new numerator is less than the degree of the denominator, we have found the complete quotient.
So, the quotient is `1x + 6`, and the remainder is `x² - 3x + 18`.
Therefore, the answer to the division problem is `1x + 6` (a polynomial).

A club collected $3,472 to buy computers. if each computer costs $680, estimate the number of computers that the club can buy explan
This is how I need to answer it:
Answer: 5 computers
Step-by-step explanation:
You would take the total amount collected and divide it by the cost of a computer.
3472/680=5.10
Since the number is not a whole number you would round down since you can not buy part of a computer. Therefore, the club can only buy 5 computers.
You have invited g people to a party and expect 80% of them to attend. You estimate that your guests will
each eat p pieces of pizza. If each pizza has s slices, how many pizzas do you expect to be eaten?
The number of pizza expected to be eaten is equal to the number of persons that attends the party and this is equal to 0.8gp/s
How to find the number of pizzas that will be eatenFrom the problem it can be deduced that
number of people invited to the party = g
number of people attending
= 80% of people invited to the party
= 80% of g
and 80% = 80 / 100 = 0.8
therefore,
= 0.8g
You estimate that your guests will each eat p pieces of pizza
= 0.8g * p
= 0.8gp
and each pizza has s slices
the number of slices = s
the number of pizza to be taken is 0.8gp/s

account c has a 3.9 % apr compounded daily ( 365 times per year). determine the account value's growth factor and percent change per compounding period.
Answer:
Step-by-step explanation:
The compound interest period rate is P = Po(1±r/t)n(t)
Here,
r = .039
t = 365
The daily rate in this situation is = .039/365
The factor for 1 compounding period for a year = (1+(.039/365))365 = 1.039768317
The growth factor is = 3.9768317%
The accounts value's growth factor is 1.0000107227, and the percent change per compounding period is 0.107227%.
What is the growth factor?
The account value's growth factor is the factor by which the account value increases each compounding period. It is given by the formula:
[tex]$growth factor$ = (1 + APR /{$compounding frequency$}) ^ {($compounding frequency$ / $period$)}[/tex]
In this case, the APR is 3.9%, the compounding frequency is 365 times per year (daily), and the period is one year. Plugging these values into the formula, we get:
growth factor = (1 + 0.039 / 365) ^ (365 / 1) = 1.0000107227
The percent change per compounding period is the amount by which the account value increases each compounding period, expressed as a percentage. It is given by the formula:
percent change = (growth factor - 1) * 100
Plugging the value of the growth factor that we calculated earlier into this formula, we get:
percent change = (1.0000107227 - 1) * 100 = 0.107227%
Therefore, the account value's growth factor is 1.0000107227, and the percent change per compounding period is 0.107227%.
