Dominic took a 20-question online quiz. He received 5 points for every correct answer. For every question he answered
incorrectly, he lost 2 points. The quiz also had a 20-point bonus for finishing in one hour or less. Since Dominic finished
the quiz in less than one hour, his score S is determined by x, the number of questions answered correctly.
Drag and drop expressions into the function to correctly define S(a).
The function that correctly defines S(x) is S(x) = 5x - 2(20 - x) + 20
How to determine the function that correctly defines S(x)We have the following definitions in the question
Correct answers = xTotal questions = 20Points for correct answers = 5Points for incorrect answers = -2Bonus for finishing in one hour or less = 20If the total questions is 20, then
Incorrect answers = 20 - x
So, the points gained/lost are
Gained = 5 * x = 5x
Lost = -2 * (20 - x) = -2(20 - x)
Bonus = 20
Add the above points to get the function S(x)
S(x) = 5x - 2(20 - x) + 20
Hence, the definition is S(x) = 5x - 2(20 - x) + 20

A circular garden has a circumference of 40.25 feet. Find the approximate diameter of the garden. Use 3.14 for π. Round to the nearest hundredth if necessary.
__ ft
The approximate diameter of the garden is 12.84 feet.
What is circumference?
The circumference of a circle is the distance around the edge of the circle or It is the perimeter or the length of the boundary of a circle. It is a measure of the total length of the circle, just like the perimeter is the measure of the total length of a polygon. The circumference is also related to the diameter and radius of a circle by the formula:
Circumference = 2πr = πd
The circumference of a circle is given by the formula C = 2πr, where C is the circumference and r is the radius. We can rearrange this formula to solve for the radius:
r = C / 2π
In this case, we are given that the circumference is 40.25 feet and π is approximately 3.14. Substituting these values into the formula, we get:
r = 40.25 / (2 x 3.14) ≈ 6.42 feet
The diameter of the circle is twice the radius, so we can find the approximate diameter by multiplying the radius by 2:
d ≈ 2 x 6.42 ≈ 12.84 feet
Rounding to the nearest hundredth, we get a diameter of approximately 12.84 feet.

The nearest Whole percent, the percent increase of women students is approximately 21%.
The percent increase of women students, we need to compare the number of women students in 2005 and 2006.
In 2005, the number of women students was 123.
In 2006, the number of women students was 149.
To find the increase, we subtract the initial value (2005) from the final value (2006):
Increase = Final Value - Initial Value
Increase = 149 - 123
Increase = 26
Next, we need to calculate the percent increase. The percent increase is given by the formula:
Percent Increase = (Increase / Initial Value) * 100
Plugging in the values:
Percent Increase = (26 / 123) * 100

Please help now. I’m very confused and i don’t no how to do this. I don’t want just the answer but a great explanation.
Answer:
First option
Step-by-step explanation:
Hi there!
The "constant additive rate of change" means a constant slope.
The slope is \(\displaystyle\frac{change \hspace{4} in \hspace{4} y}{change \hspace{4} in \hspace{4} x}\).
First of all, if the slope is constant, then we know immediately that it must be a linear function, a line. The change in y is forever the same according to the change in x. Knowing this, the second option is for-sure wrong (it's not a straight line).
Now, let's look at the first option. It is a linear function, which means it has a constant slope. However, we're given that the slope is \(-\displaystyle \frac{1}{4}\). This means that for a line, whenever it travels 4 units to the right, it travels 1 unit down (it travels down whenever the slope is negative and up whenever the slope is positive).
This is the exact case for the first option. Look at the point (-2,2) on the line. When we move 4 units to the right of that point, The line would have moved 1 unit down. We would reach the point (2,1).
Therefore, the correct answer would be the first option.
I hope this helps!
How do you isolate the variable in an inequality?
For one to isolate the variable by using equation rules. Inverse inequality sign if multiplying/dividing by negative. Steps to isolate variable in inequality: Simplify, move constants with inverse operations. Divide coefficient to isolate variable. Reverse direction if using negative number.
What is the variable?Inequalities require you to apply the same principles as those used in equations when isolating a variable. For example, if there is an inequality 3x - 5 < 7. one can isolate the variable, by first:
Add 5 to both sides to be: 3x < 12.
Then divide both sides by 3: x < 4.
So, the variable x is one that is isolated, and the solution to the inequality is one where x < 4.

The measure of side length x in the right triangle is approximately 6.03 cm.
What is the measure of side length x?The figure in the image is a right triangle having one of its interior angle at 90 degrees.
From the figure:
Angle θ = 37 degrees
Adjacent to angle θ = 8 cm
Opposite to angle θ = x
To solve for the missing side length x, we use the trigonometric ratio.
Note that: tangent = opposite / adjacent
Hence:
tan( θ ) = opposite / adjacent
Plug in the given values and solve for x:
tan( 37 ) = x / 8
x = tan( 37 ) × 8
x = 6.03 cm
Therefore, the value of x is 6.03 cm.

Find cot theta if 180° < theta < 270° and cos theta = - sqrt 3/2
Answer:
cot theta = -√3
Step-by-step explanation:
we are given that cos theta = - √3/2 within the range 180° < theta < 270° and
since cos theta = adj/hyp
adj = - √3
hyp = 2
Get the opposite using the pythagoras theorem
hyp^2 = opp^2 + adj^2
2² = opp² + (-√3)²
4 = opp² + 3
opp² = 4-3
opp² = 1
opp = 1
tan theta = opp/adj
tan theta = - 1/√3
Recall that cot theta = 1/tan theta
cot theta = 1/(-1/√3)
cot theta = -√3

How much would you need to deposit in an account now in order to have $2000 in the account in 5 years? Assume the account earns 5% interest compounded monthly.
I need to deposit $1558.41 to have $2000 in the account in 5 years.
What is compound interest?
The interest charged on a debt or deposit is known as compound interest. It is the idea that we use the most regularly. Compound interest is calculated for a sum based on both the principal and cumulative interest.
∴ Compound interest = P(1 + \(\frac{r}{100*12}\))ⁿ (∵ for monthly interest)
P = Principal
r = rate of interest per month
n = number of months
Given:
r = 5% per month
n = 5 years = 5*12 = 60 months
CI = P (1+5/(12 * 100))⁶⁰
2000 = P(1.0041)⁶⁰
2000 = P(1.2834)
P = 1558.41
Therefore, the amount required to deposit is 1558.41 dollars to get 2000 dollars after 5 years with 5 percent interest per month.

An electronics store usually sells 18 remote control devices per week at a retail price of $12.49. This week the manager put the remotes on sale for a markdown of 20%, and sold 25 of them. How much more revenue was earned this week by having the sale?
Therefore , the solution of the given problem of percentage comes out to be the transaction increased the store's revenue by $24.98.
What exactly does a percentage mean?A statistic or number that is stated as a proportion of 100 is referred to as a "a%" in statistics. Additionally, the terms "pct," "pct," and "pc" are not commonly used. However, it is commonly denoted by the symbol "%". There are no dimensions; the percentage total is flat. Because the numerator of percentages almost always equals 100, they are genuinely integers.
Here,
The shop offers 18 remote controls each week for a suggested retail price of $12.49 prior to the sale.
The following formula can be used to determine the store's monthly revenue in the absence of the sale:
=> 18 x $12.49 = $224.82
This formula can be used to determine the selling price:
=> $12.49 x 0.8 = $9.992
The retailer sold 25 remote controls during the sale, so the proceeds from the transaction can be determined as follows:
=> 25 x $9.992 = $249.80
We must deduct the initial revenue from the revenue produced by the sale in order to compute the increase in revenue as a result of the sale:
=> $249.80 - $224.82 = $24.98
As a result, the transaction increased the store's revenue by $24.98.

Yes, because (-1, -5) is on the line.
Is the ordered pair (-1, -5) is a solution to inequality y < -3/4 x - 1
No, because (-1, -5) is above the line.
How to find if the ordered pair is a solutionThe inequality y < -3/4x - 1 represents a line on a coordinate plane.
The inequality symbol "<" means that the values of y that satisfy the inequality are those that are strictly less than the value of the right-hand side of the equation.
So, for any given x-value, all y-values that are less than the corresponding y-value on the line satisfy the inequality.
In this case, when x = -1, the corresponding y-value on the line is -3/4 * -1 - 1 = 1/4.
Since -5 is greater than 1/4, it means that (-1, -5) is above the line and does not satisfy the inequality y < -3/4x - 1.
