Using balanced billing, the monthly payment is $278
What will be their monthly payment?Using balanced billing to determine their monthly payment, we simply need to divide their total annual payment by the total number of months in a year. This will result to dividing the entire annual bill by 12 to determine the monthly payment.
Given that the Ross family spent $3,336 for electricity last year, we can calculate their monthly payment as follows:
Monthly payment = Total cost / Number of months
Monthly payment = $3,336 / 12
Monthly payment = $278
Therefore, the Ross family's monthly payment for balanced billing will be approximately $278.

Compute the monthly payments for each add-on interest loan. The amount of the loan is $1150. The annual interest rate is 6%. The term of the loan is 4 years.
The monthly payments for each add-on interest loan will be $29.71.
Given Information and Formula Used
Principal Amount, P = $1150
Rate of Interest, R = 6%
Duration of loan in years, T = 4
The formula for simple interest is given as,
I = (P × R × T)/100
Calculating the Add-On Interest For Each Month
Interest, I = (P × R × T)/100
Substituting the values of P, R, and T in the above formula, we get,
I = $ (1150 × 6 × 4)/100
I = $ 27600/100
I = $276
Calculating the Total Monthly Payment With Interest
Amount of add-on interest loan, A = P + I
A = $1150 + $276
A = $1,426
Monthly payment with interest = A/(4×12)
= $ 1426/48
= $29.71
Hence, the monthly payments for each add-on interest loan would be $29.71.

Determine the interval(s) on which the given function is decreasing?
Answer:
[tex](-\infty, -1) \cup (0, \infty)[/tex]
Step-by-step explanation:
The function is decreasing if, as x increases, the value of the function (y) gets smaller. This means as you read the graph from left-to-right, the function is decreasing if the graph is falling.
From -infinity to -1, the graph is falling, then the graph rises (f is increasing) until x =0, then the graph falls again from x = 0 to infinity.
what is f(x) in the expression?
[tex]f(x) = 7x {}^{2} - 3x {}^{4} [/tex]
Select the correct answer. What is the domain of y = tan (x)?
At 90 degrees, the tangent of x is undefinable.
What does determining the domain mean?The collection of all x-values that can cause the function to "work" and produce actual y-values is known as the domain. Keep in mind that a fraction's denominator (bottom) cannot be zero when determining the domain. The integer that comes after a square root symbol in this section needs to be positive.The domain of y = tan (x):
y = tan(x)
Except for 90, all sets of positive real numbers fall within the domain of y = tan(x).
At 90 degrees, the tangent of x is undefinable.
Due to the exclusion of 90, all sets of positive real numbers are included in the domain of y = tan(x).

The table below shows some inputs and outputs of the invertible function f with domain all real numbers.
The values of f⁻¹(f(6.022)) is 6.022 and f⁻¹(10) + f(-6) is 4
How to evaluate the function?As a general rule;
f⁻¹(f(x)) = x
This means that:
f⁻¹(f(6.022)) = 6.022
Also, we have:
f⁻¹(10) + f(-6)
From the table of values, we have:
f⁻¹(10) = -6 and f(-6) =10
So, we have:
f⁻¹(10) + f(-6) = -6 + 10
Evaluate
f⁻¹(10) + f(-6) = 4
Hence, the values of f⁻¹(f(6.022)) is 6.022 and f⁻¹(10) + f(-6) is 4

First, we need to understand that these two triangles are
similar.
we know this because their lines (the arrows) prove they are the same direction. A similar triangle does
NOT mean they are proportional,
they are just similar by ratio.
Lets call the triangle on the left ABC and the triangle on the right A'B'C'.
I will attach an image of the labels.
Because they are similar triangles, angle A is the same as angle A'. Angle B is the same as angle B', angle C is the same as angle C'.
Based on that information, we know xº is = 65º. We know that the interior angles add up to 180º. So for triangle A'B'C', we can do 180º-40º-65º which is 70º. This means angle C' is 70º.
Now the important part is getting yº. A line is 180º. That means that 180º-70º=yº which is 110º.
If you do not understand anything, please let me know and I will try to teach you.

Compute the monthly payments for each add-on interest loan. The amount of the loan is $1150. The annual interest rate is 6%. The term of the loan is 4 years
The monthly payments for each add-on interest loan is $29.7.
What is interest?Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time. Contrary to compound interest, where we add the interest of one year's principal to the next year's principal to compute interest, the principal amount under simple interest remains constant.
According to the question,
Principal (P) = $1150
Rate of Interest(R) = 6%
Time (T) = 4 years
The interest is calculated as follows:
SI = (P × R × T)/100
SI = (1150 × 6 × 4)/100
SI=$ 276
Amount (A) = P + SI
A = $(1150 +276)
A = $1426
Monthly payment with interest = A/(4×12)
= $ 1426/48
= $29.7

The x-intercept of a line is 2 and the y-intercept is 4. Explain how to use this information to write the equation of the line.
Answer:
y = -2x + 4
Step-by-step explanation:
The x-intercept would be the point (2,0) and the y intercept would have the point (0,4). Once we know two points we can write the equation in the line intercept for of y = mx + b.
We need to find the slope and the y intercept. The slope is the steepness of the line and it is the change in y over the change in x.
The ordered pairs are written in the form of (x, y). From our two points, we will subtract the y's to find the top number of our fraction.
0 - 4 = -4 that is the numerator (top number) of our slope. We do the same with the two x numbers that we have been given.
2 - 0 = 2 This is our numerator (or bottom number of our slope)
Our slope is -4 /2 to simplify, we divide the top and bottom number by 2 to get -2 / or just -2
Now that we have the slope we need to find the y-intercept. We can use either of our original two points and our slope to determine the y-intercept. It does not matter if you use the point (2,0) or (0,4). I will use (2,0) and the slope of -2
y = mx + b
0 = -2(2) + b
0 = -4 + b add 4 to both sides of the equation
4 = b
Now that we have the slope and the y-intercept, we can write the equation
y = mx + b
y = -2x + 4

b) What percentage of the widget weights lie between 24 and 57 ounces?
c) What percentage of the widget weights lie below 79
Using the Empirical Rule, it is found that:
a) 68% of the widget weights lie between 35 and 57.
b) The percentage is 81.5%.
c) The percentage is 99.85%.
What does the Empirical Rule state?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.For this problem, we have that:
In item a, 68% of the widgets are within 1 standard deviation of the mean, hence between 35 and 57.In item b, between 2 standard deviations below the mean(95% of 50% due to the symmetry of the normal distribution) and 1 above(68% of 50%), hence the percentage is: P 34% + 47.5% = 81.5%.For item 3, below 3 standard deviations above the mean, hence removes only the top 0.15%, hence 99.85%.More can be learned about the Empirical Rule at https://brainly.com/question/4079902

What is an equation?An equation is a mathematical expression that show the relationship between two variables.
Given 9cos(sin¯¹(x)) = √(81 – 81x²), we need to show L.H.S = R.H.S
So, L.H.S = 9cos(sin¯¹(x))
