Answer:
The ring in 2020 costs around $3,931.2.
Step-by-step explanation:
We know how much the ring cost in 2018 and we know the percentages of the value as years go by.
To solve this, we will need to put the percentages into decimals, and since we are adding value, add an additional 1 [whole] in both decimals.
Should look like this:
2019: 1.04
2020: 1.08
Multiply the cost with the first year:
3500 x 1.04 = 3640
The ring costs $3,640 in 2019.
Then it says the ring went up by %8 percent in 2020.
Multiply the cost from last year with the current year:
3500 x 1.08 = 3931.2
The ring costs $3,931.2 in 2020.
I hope this helps!

How do you do this question without looking at the answer choices?
Answer:
Take a look at the 'proof' below
Step-by-step explanation:
The questions asks us to determine the anti-derivative of the function f(x) = 4x^3 [tex]*[/tex] sec^2 [tex]*[/tex] x^4. Let's start by converting this function into integral form. That would be the following:
[tex]\mathrm{\int \:4x^3sec^2x^4dx}[/tex]
Now all we have to do is solve the integral. Let's substitute 'u = x^4' into the equation 'du/dx = 4x^3.' We will receive dx = 1/4x^3 [tex]*[/tex] du. If we simplify a bit further:
[tex]\mathrm{\int \:\:sec^2\left(u\right)du}[/tex]
Our hint tells us that d/dx [tex]*[/tex] tan(x) = sec^2(x). Similarly in this case our integral boils down to tan(u). If we undo the substitution, we will receive the expression tan(x^4). Therefore you are right, the first option is an anti-derivative of the function f(x) = 4x^3 [tex]*[/tex] sec^2 [tex]*[/tex] x^4.
Show the steps for the merge sort to sort the following values: {199,16,186,115,158,135,186,14,10}
Answer:
Step-by-step explanation:
STEP 1: Show the array of values.
The array is {199, 16, 186, 115, 158, 135, 186, 14, 10}
STEP 2: Determine the number of elements/values.
Here, it is 9
STEP 3: Starting from zero, assign number tags to each value.
Since the values are 9 in number, the numerical tags will be 0, 1, 2, ..., 8

Answer: 12.25 or Approximately 12.3
Step-by-step explanation:
To solve this problem, we first need to solve for x. We are given with 2ˣ=7.
To get x alone, we want to use natural log, or ln.
[tex]xln(2)=ln(7)[/tex] [once you find ln of both sides, you bring the x to the front]
[tex]x=\frac{ln(7)}{ln(2)}[/tex] [divide both sides by ln(2)]
[tex]x=2.81[/tex]
We now know that x is approximately 2.81. We can plug that in to find 4ˣ⁻¹.
[tex]4^(^x^-^1^)[/tex] [plug in x]
[tex]4^(^2^.^8^1^-^1^)[/tex] [parenthesis]
[tex]4^{1.81}[/tex] [exponent]
[tex]12.3[/tex]
The answer is approximately 12.3. To get a more exact answer, you would plug in [tex]\frac{ln(7)}{ln(2)}[/tex] into x.
[tex]4^{\frac{ln(7)}{ln(2)}-1 }[/tex]
[tex]12.25[/tex]
The exact answer would be 12.25. This is close to 12.3 since it is rounded up to one decimal place.

Answer:
z = 80°
Step-by-step explanation:
The sum of the interior angles would equal to 360°
100° + 60° + 120° = 280°
360° - 280° = 80°
Answer:
z = 80
Step-by-step explanation:
A quadrilateral has angles that sum to 360°
E + C + G + F = 360
100 + 60 + 120 + F = 360
Combine like terms
280 + F = 360
F = 360 - 280
F = 80
We know that ABCD is similar to FECG
This means that the measure of A = measure of F
z = 80
John's electricity bill costs $20.90 per month plus $1.23 per kilowatt hour. How many kilowatt hours can he use and keep his monthly cost no more than $109
Answer:
71.63 kilowatts hours
Step-by-step explanation:
We are told in the question:
John's electricity bill costs $20.90 per month plus $1.23 per kilowatt hour.
We are to find, How many kilowatt hours can he use and keep his monthly cost no more than $109.
Step 1
$109 - $20.90
= $88.1
$88.1 is the amount left to spend on killowatts of electricity per hour after removing the normal monthly electricity bill in a month
Step 2
$1.23 = 1kilowatts per hour
$88.1 = y kilowatts per hour
Cross Multiply
= $1.23 × y kilowatts per hour = $88.1 × 1 kilowatts per hour
y kilowatts per hour = $88.1 × 1 kilowatts per hour/ $1.23
= 71.62601626kilowatts hour.
Approximately = 71.63 kilowatts hour
Therefore, John can use 71.63 kilowatts per hour and keep his monthly cost no more than $109
Answer:

Which representation shows a proportional relationship between x and y?
Answer: D
Step-by-step explanation:
To have a proportional relationship, the value of y divide by x has to have the same constant value and if you were to graph it, it has to go through the origin.
A is not proportional because it is not going through the origin.
B is also not proportional because it is also not going through the origin.
Now to find out if C is proportional divide the y value by x so see if they all have a constant change.
8/2 =4
16/4 = 4
24/8 = 3
32/ 12 = 2.6
This is also not proportional .
D. 3/2 = 1.5
6/4 = 1.5
12/ 8 = 1.5
18/12 = 1.5
This represents a proportional relationship because they all have a constant change
The proportional relationship between x and y will be given by option D.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
Let's check all the options:
Option A because the line has intercept.
Option B because the line is zero.
Option C:
The slope is given as,
Slope = (16 - 8) / (4 - 2) = 4
Slope = (24 - 16) / (8 - 4) = 2
Slope = (32 - 24) / (12 - 8) = 2
Option D:
The slope is given as,
Slope = (6 - 3) / (4 - 2) = 3/2
Slope = (12 - 6) / (8 - 4) = 3/2
Slope = (18 - 12) / (12 - 8) = 3/2
The proportional relationship between x and y will be given by option D.

un angulo θ mide 750° y es coterminal con
Answer:
El ángulo de 750º es coterminal con los ángulos de 29.88º y 389.88º.
Step-by-step explanation:
Antes de comenzar este enunciado, cabe recordar que dos ángulos en posición estándar son coterminales cuando tiene un lado terminal común, además que el sistema sexagesimal tiene un período de 360º, entonces todo ángulo satisface la siguiente condición:
[tex]\theta = 360\cdot x[/tex], [tex]\forall \,x \in \mathbb{R}[/tex].
Si sabemos que [tex]\theta = 750^{\circ}[/tex], el múltiplo [tex]x[/tex], que indica el número de revoluciones dadas es:
[tex]x =\frac{\theta}{360}[/tex]
[tex]x = \frac{750^{\circ}}{360^{\circ}}[/tex]
[tex]x = 2.083[/tex]
El número de ángulos coterminales equivale al número entero de revoluciones. Y la posición coterminal más pequeña queda determinada por el residuo, que es igual a la diferencia entre el total de revoluciones (2.083) y el número de revoluciones enteras. (2) En este caso, existen dos angulos coterminales cuyas magnitudes determinamos a continuación:
[tex]\theta_{1} = (0 + 0.083)\cdot (360^{\circ})[/tex]
[tex]\theta_{1} = 29.88^{\circ}[/tex]
[tex]\theta_{2} = (1 + 0.083)\cdot (360^{\circ})[/tex]
[tex]\theta_{2} = 389.88^{\circ}[/tex]
El ángulo de 750º es coterminal con los ángulos de 29.88º y 389.88º.

factor the expression 36xyz + 24xy - 16x by dividing each term by a common factor. what are the common possible factors?
Answer:
4(9xyz+6xy-4x)
Step-by-step explanation:
Since the GCF of all the numbers is 4 you would just divide each term by 4 and make the 4 go outside of the Parenthesis so you get 4(9xyz+6xy-4x)
The common possible factors are 4x and [9yz + 6y - 4] after dividing and multiplying by 4x in the expression.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
It is given that:
The expression is:
= 36xyz + 24xy - 16x
As we can see; the common factor in the expression is 4x
The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
Divide by 4x in the expression and multiply by 4x:
We get:
= 4x[(1/4x)36xyz + 24xy - 16x]
= 4x[9yz + 6y - 4]
Thus, the common possible factors are 4x and [9yz + 6y - 4] after dividing and multiplying by 4x in the expression.
