Answer: Let x = the charge in 1st city before taxes
Let y = the charge in 2nd city before taxes
Set up equation before taxes.
y = x - 1500 eq1
Set up equation for total tax paid.
0.065x + 0.06y = 378.75 eq2
Substitute eq1 into eq2.
0.065x + 0.06(x - 1500) = 378.75
0.065x + 0.06x - 90 = 378.75
0.125x - 90 = 378.75
0.125x = 468.75
x = 3750
Substitute this value of x into eq1.
y = 3750 - 1500
y = 2250
The hotel charge in city one is $3750 and the hotel charge in city two is $2250.

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.

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.

An article reported that for a sample of 60 kitchens with gas cooking appliances monitored during a one-week period, the sample mean CO2 level (ppm) was 654.16, and the sample standard deviation was 163.02.
(a) Calculate and interpret a 95% (two-sided) confidence interval for true average CO2 level in the population of all homes from which the sample was selected. (Round your answers to two decimal places.)
The 95% confidence interval for true average CO2 level in the population of all homes from which the sample was selected is given as follows:
(612.05, 696.27).
The interpretation is that we are 95% sure that the population mean is between these two values.
How to obtain the confidence interval?The confidence interval is obtained using the t-distribution, as we have the standard deviation for the sample instead of the standard deviation for the population.
The bounds of the interval are given by the equation presented as follows:
[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]
In which the variables of the equation are presented as follows:
[tex]\overline{x}[/tex] is the sample mean.t is the critical value.n is the sample size.s is the standard deviation for the sample.The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 60 - 1 = 59 df, is t = 2.0010.
The remaining parameters are given as follows:
[tex]\overline{x} = 654.16, s = 163.02, n = 60[/tex]
Hence the lower bound of the interval is of:
654.16 - 2.001 x 163.02/sqrt(60) = 612.05.
The upper bound of the interval is of:
654.16 + 2.001 x 163.02/sqrt(60) = 696.27.

Convert the complex number z = 3(cos(7pi/6)+ i sin (7pi/6)) from polar to rectangular form. Make sure to evaluate the trigonometric functions.
Answer:
In rectangular form, a complex number is expressed as $x + yi$, where $x$ and $y$ are the real and imaginary parts, respectively. The conversion from polar form to rectangular form is done using the following equations:
$x = r \cos \theta$
$y = r \sin \theta$
where $r$ is the magnitude (or modulus) of the complex number and $\theta$ is the argument (or phase) of the complex number.
In the given problem, we are given the complex number $z = 3(cos(7pi/6)+ i sin (7pi/6))$. We can write this in polar form as $z = 3 \cdot cis(7pi/6)$, where $cis(x) = cos(x) + i \cdot sin(x)$. Thus, we have $r = 3$ and $\theta = 7pi/6$. Using the equations above, we can convert this to rectangular form to obtain:
$x = r \cos \theta = 3 \cos (7pi/6) = -\frac{3}{2}$
$y = r \sin \theta = 3 \sin (7pi/6) = \frac{\sqrt{3}}{2}$
Therefore, the rectangular form of the complex number is $-\frac{3}{2} + \frac{\sqrt{3}}{2} i$.

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).

What is √75 in simplified form?
Answer:
The square root of 75 can be written as √75. To simplify this expression, we can use the property that the square root of a product is equal to the product of the square roots of the factors. In this case, we can factor 75 as the product of 25 and 3:
√75 = √(25 x 3)
We can then apply the property of the square root of a product to simplify the expression:
√75 = √(25 x 3) = √25 x √3
We can further simplify the expression by applying the property that the square root of a perfect square is equal to the number itself. Since 25 is a perfect square, we can simplify √25 to 5:
√75 = √(25 x 3) = √25 x √3 = 5 x √3
Therefore, the simplified form of √75 is 5 x √3. This means that the square root of 75 is equal to 5 times the square root of 3.
