Student changes equation to function notation. Student explains clearly what the graph of the equation represents.
Student graphs the equation and labels the intercepts correctly.
Student writes at least three sentences explaining how the graphs of the two equations are the same and how they are different.
1. The equation to slope-intercept form is y = -2/3(x) + 490. The slope is -2/3 and the y-intercept is 490.
2. You should start at the y-intercept (0, 490) and move right by 3 units and downward by 2 units, and then connect the points.
3. The equation in function notation is f(x) = -2/3(x) + 490. The graph of the function is the rate of change with respect to the number of sandwich lunch sold.
4. A graph of the function with intercepts is shown below.
5. The graphs of the functions for the two months both have the same slope but different y-intercept and x-intercept.
How to change the equation to slope-intercept form?In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is given by this mathematical equation;
y = mx + b
Where:
m represent the slope or rate of change.x and y are the points.b represent the y-intercept or initial value.Based on the information provided above, a linear equation that models Sal's Sandwich Shop's profit is given by;
2x + 3y = 1,470
By subtracting 2x from both sides of the equation and dividing by 3, we have:
2x + 3y - 2x = 1,470 - 2x
y = -2/3(x) + 490
Therefore, the slope is -2/3 and the y-intercept is 490.
Part 2.
In order to graph the equation by using the slope-intercept method, you would start at the y-intercept (0, 490) and move right by 3 units and down by 2 units, and then connect the points.
Part 3.
Next, we would write the equation in function notation as follows;
f(x) = -2/3(x) + 490
where:
f(x) represents the number of wrap lunch sold.x is the number of sandwich lunch sold.The graph represents the rate of change of the function with respect to the number of sandwich lunch sold.
Part 4.
In this context, we would use an online graphing calculator to plot the linear function as shown in the image attached below.
Part 5.
Assuming Sal's total profit on lunch specials for the next month is $1,593 and the profit amounts remain the same, a system of equations to model this situation is given by:
2x + 3y = 1593; y = -2/3(x) + 531.
2x + 3y = 1,470; y = -2/3(x) + 490.
In conclusion, we can logically deduce that the graphs of the functions for the two months both have the same slope but different y-intercept and x-intercept.

Identify whether the statement represents an exponential function. The height of a projectile = at time t is represented by the function h(t) = -4.9t^2 + 18t + 40. a) Yes, the statement represents an exponential function. b) No, the statement does not represent an exponential function_ Show your work and explain, in your own words, how you arrived at your answer_
The correct answer is option (b) No, the statement does not represent an exponential function, h(t) = -4.9t² + 18t + 40 is a quadratic function and not an exponential function.
An exponential function is a mathematical function in which the variable is in the exponent. Exponential functions follow the form f(x) = a^x, where a is the base and x is the exponent.
The given statement is h(t) = -4.9t² + 18t + 40, which does not represent an exponential function. The value of t is not in the exponent in this case. Instead, it's a quadratic equation, which is in the form of h(t) = at² + bt + c.
Therefore, the correct answer is option (b) No, the statement does not represent an exponential function.
Explanation:
An exponential function can also be represented by the general form y = ab^x, where b > 0 and b ≠ 1. When plotted on a graph, the curve of an exponential function rises or falls at an increasing rate, depending on whether b is greater than or less than 1, respectively.
A quadratic equation is an equation of the form ax² + bx + c = 0, where a ≠ 0, and x represents a variable. Quadratic equations are second-degree equations, which means the highest exponent of the variable is two.
Therefore, h(t) = -4.9t² + 18t + 40 is a quadratic function and not an exponential function.

Answer:
∠ RPQ = 28°
Step-by-step explanation:
Since PS = PQ then Δ SPQ is isosceles and the base angles are congruent.
∠ SPQ = ∠ SQP = x
Thus ∠ RQP = ∠ SQR + ∠ SQP = 34 + x
The sum of the 3 angles in Δ RPQ = 180°, thus
x + x + 34 + 90 = 180
2x + 124 = 180 ( subtract 124 from both sides )
2x = 56 ( divide both sides by 2 )
x = 28
Thus

T/F: The proportion in the body of a normal distribution can never be less than 0.50.
This statement ''The proportion in the body of a normal distribution can never be less than 0.50.'' is false because the proportion in the body of a normal distribution can be less than 0.50, depending on the location of the mean and the spread of the distribution.
In fact, for a normal distribution with a mean of μ and standard deviation of σ, approximately 68% of the area under the curve falls within one standard deviation of the mean (i.e., between μ - σ and μ + σ), which means the proportion in the body of the distribution is about 0.68.
The remaining 32% is split evenly between the tails of the distribution, which means the proportion in each tail is about 0.16.
So, the proportion in the body of the distribution is greater than 0.50.

Rich earns $35 per week mowing lawns in his neighborhood which expression can be used to show how much money he earns in 8 weeks
The expression that can be used to show how much money Rich earns in 8 weeks is: 8 * $35.
Rich earns $35 per week mowing lawns in his neighborhood.
We want to find out how much money he earns in 8 weeks.
To find the total amount of money Rich earns in 8 weeks, you can multiply the amount he earns per week ($35) by the number of weeks (8). This is because each week, Rich earns $35, so in 8 weeks, he will earn 8 times that amount.
So, the expression to calculate how much money Rich earns in 8 weeks is 35 dollars/week * 8 weeks.
By multiplying the amount earned per week by the number of weeks, we can determine the total earnings over the given period. In this case, Rich would earn a total of $280 in 8 weeks by mowing lawns in his neighborhood.

The Sloan family stayed in a hotel room for 6 nights while on vacation. The total cost before tax was $1,170. If the hotel room tax rate in the city is 12%, what was the total cost for the hotel room?
Answer:
Total cost for the hotel room is $1310.4
Step-by-step explanation:
The total cost before tax was $1170.
The tax rate is 12%.
So, tax paid = 12%(1170)
Convert 12% to decimal. We get 12% as 0.12
So, tax =0.12*1170 =140.4
So, total cost for the hotel room = $140.4 +$1170 =$1310.4

The variance of the weights of the 10 subjects is 158.6527 kg^2.
The variance of a sample data measures how spread out the individual values are from the mean. To calculate the variance, you need to square the standard deviation.
Given that the standard deviation of the weights of the 10 subjects is 12.5915 kg, we can calculate the variance using the following steps:
1. Square the standard deviation:
Variance = Standard deviation^2
Therefore, Variance = 12.5915^2 = 158.6527 kg^2

(Type your answer in interval notation. Use a comma to separate answers as needed. Type an integer or a simplified fraction.)
B. The function is not increasing on any interval.
The function is not increasing on any interval.
First, we need to find the first derivative of the function:
y = -3x² - 5x + 2
y' = -6x - 5
Next, we need to find the critical points of the function by setting the first derivative equal to zero:
-6x - 5 = 0
-6x = 5
x = -5/6
Now, we need to use the second derivative test to determine where the function is increasing, decreasing, concave up, and concave down:
y'' = -6
Since the second derivative is a constant negative value, the function is concave down on the entire domain of x.
Now, we can use the first derivative and the critical point to determine where the function is increasing and decreasing:
When x < -5/6, the first derivative is positive, so the function is increasing.
When x > -5/6, the first derivative is negative, so the function is decreasing.
Therefore, the function is not increasing on any interval.
In interval notation, the function is increasing on the interval (-∞, -5/6) and decreasing on the interval (-5/6, ∞).
So, the correct choice is B. The function is not increasing on any interval.

According to the statement
we have to find that the gross annual income which is subjected to the tax.
So, For this purpose, we have given information that is:
he has a wife, 4 children and 2 parents.
And the income required for all this is :
For himself = $3000
For wife = $2000
For 4 children = $4000*4 = $16000
For 2 parents = $5000 *2 = $10,000
And then
He paid an income tax of $1474 for the year 2018.
And
the gross tax payable for the first $40,000 is $550 and the tax rate for the rest is 7%.
Then
If tax for first 40,000 is 550 then it is clear that the annual amount is more than the 40,000.
So,
Left amount he pays as tax for more than 40,000 = 1474 - 550
Left amount he pays as tax for more than 40,000 = 924

The population of a colony of mosquitoes obeys the law of uninhibited growth. If there are 1000 mosquitoes initially and there are 1600 after 1 day, what is the size of the colony after 4 days? How long is it until there are 70,000 mosquitoes?
The number of mosquitoes on the colony after 4 days is 2800.
The number of days that there are 70,000 mosquitoes will be 114 dad.
How to illustrate the population?The population of a colony of mosquitoes obeys the law of uninhibited growth and there are 1000 mosquitoes initially and there are 1600 after 1 day. The common difference will be:
= 1600 - 1000
= 600
The formula for the arithmetic sequence will be:
= a + (n - 1)d
a = 1000
d = 600
n = 4
The colony after 4 days will be:
= a + (n - 1)d
= 1000 + (4 - 1)600
= 1000 + 1800
= 2800
The number of days that there are 70,000 mosquitoes will be:
a + (n - 1)d = 70000
1000 + 600(n - 1) = 70000
1000 + 600n - 600 = 70000
Collect like terms

Which inequality is represented in the graph below?
Answer:
\(A) \: y\leq -3x+4\)
Answer:
A) y ≥ -3x + 4
Step-by-step explanation:
Given the graph of an inequality, where it shows that the y-intercept is (0, 4), and the line has a negative slope (as it declines from left to right). To figure out the value of the slope, choose two points from the graph, and substitute its values into the slope equation,
m = (y2 - y1)/(x2 - x1)
Let (x1, y1) = (0, 4)
(x2, y2) = (2, -2)
m = (-2 - 4)/(2 - 0)
m = -6/2
m = -3
Now that we have the value of the slope, m = -3, and the y-intercept, b = 4:
We need to determine which part of the region is shaded. Choose a test point that is not on the graph. Let's use the point of origin, (0, 0) to see whether it is included as a solution:
Option A: y ≥ -3x + 4
Substitute values of (0, 0) into the inequality statement:
0 ≥ -3(0) + 4
0 ≥ 0 + 4
0 ≥ 4 (False statement). The shaded region must not contain the given test point, (0, 0), which is actually the case in your given graph. The right-half plane is the shaded region. Hence, y ≥ -3x + 4 is the correct inequality statement that represents the graph.
The answer cannot be y ≤ -3x + 4 because if you plug in the test point into y ≤ -3x + 4, it will provide a true statement.
y ≤ -3x + 4
0 ≤ -3(0) + 4
0 ≤ 0 + 4
0 ≤ 4 (True statement, which means that the region where the test point is located should be shaded).
Therefore, the correct answer is Option A) y ≥ -3x + 4

A researcher collected the number of letters in each of 200 first names. The data are found to be normally distributed with a mean of 5.82 and a standard deviation of 1.43.
What percentage of first names have seven letters or less?
82.5%
99.8%
79.4%
84.1%
The data are found to be normally distributed with a mean of 5.82 and a standard deviation of 1.43. The answer will be the later. 90.62%
How to find the percentage?To find the percentage of first names with 7 letters or less, we need to use the Z-score formula to determine how many standard deviations the value 7 is from the mean.
Z = (7 - 5.82) / 1.43
The Z-score indicates how many standard deviations the value 7 is from the mean. A positive z-score indicates a value above the average, and a negative z-score indicates a value below the average.
A Z-score table or calculator can then be used with the standard normal distribution function to find the cumulative probability to which the Z-score compare. This cumulative probability is the percentage of data values that are 7 or less. In this case, Z = 1.36 and the cumulative probability is approximately 0.9062. This means that about 90.62% of given names are seven letters or less of him. So the answer will be the later. 90.62%

a disk 2 inches in diameter is thrown at random on a tiled floor, where each tile is a square with sides 4 inches in length. let c be the event that the disk will land entirely on one tile. in order to assign a value to p(c), consider the center of the disk. in what region must the center lie to ensure that the disk lies entirely on one tile?
The probability that the disk will land entirely on one tile is 1/4.
For, this question I have attached an image which shows that the inner red square is the area of a tile in which the centre of the disk could land and the disk would be contained entirely within the tile while the grey area is the area in which the centre of the disk would land and the disk would not be entirely contained within the tile.
Now, The area of a square is the square of side length. The inner square has an area of 2² = 4 and the entire square (red and grey regions combined) has an area of 4² = 16.
Hence, the probability that the disk's centre lands in the red zone is the area of the red zone, divided by the total area, which is
4/16 = 1/4
