Speed = 95 miles per hour
a. to express it in feet per second
1 mile = 5280 ft
1 hour = 3600 seconds
(95 x 5280 )/3600 = 139.33 ft/s
b. Speed = distance / time
Time = Distance / speed
Distance = 60ft
Time = 60ft / 139.33 ft /s = 0.43 seconds
c.
speed= distance / time
S = 60 ft / 1 sec = 60 ft/s
Linear function gis shown in the graph. Write the slope-Intercept form of the equation representing this function.
To find the equation of the line in slope intercept form the first step is to find the slope of the given line:
[tex]m=\frac{y2-y1}{x2-x1}[/tex]In this formula, m is the slope of the function, y2 and y1 are the y coordinates of 2 points on the line, and x2 and x1 are the x coordinates of the same 2 points, for example, they can be (-1,3) and (0,1):
[tex]m=\frac{1-3}{0-(-1)}=-\frac{2}{1}=-2[/tex]The slope of the line is -2.
Now, we can use the y intercept of the graph of g, which is 1.
The slope intercept form of the equation follows the following general structure:
[tex]y=mx+b[/tex]Where m is the slope of the line and b is the y intercept. Use the known values to replace them on the equation. The intercept form of the equation is:
[tex]y=-2x+1[/tex]Graph the following function using the techniques of shifting, compressing, stretching and or reflecting.
Answer:
Domain: (-∞, ∞)
Range: (-∞, ∞)
Explanation:
The parenting function of g(x) = (x + 3)³ + 5 is f(x) = x³.
The graph of f(x) = x³ is
Then, if we have a function g(x) = f(x + c), we can say that g(x) is the graph of f(x) shifted c units to the left and if we have a function g(x) = f(x) + c, we can say that g(x) is the graph of f(x) shifted c units up
In this case, g(x) = f(x + 3) + 5 because
g(x) = f(x + 3) + 5
g(x) = (x + 3)³ + 5
So, g(x) has the graph of f(x) shifted 3 units to the left and 5 units up.
Therefore, the graph of g(x) is
Now, the domain is the set of values that x can take and the range is the set of values that y can take, so the domain and range are all the real number.
Domain: (-∞, ∞)
Range: (-∞, ∞)
View the tables:How are the values in each table growing?Which table shows common differences? Explain your reasoning.Which one shows common factors? Explain your reasoning.
In first table, where the height of the water is considered, every minute the water rises by 3 cm.
In second table, where possible outcome is considered, for increase in one coin the outcome increases by a factor of two.
The first table, where the height of the water is considered, shows common difference. As it increases equally every minute.
The second table, where possible outcome is considered,shows a common factor as all the values are divisible by 2. So the common factor is 2.
Twice a number, decreased by 4, is at least 12. Which of the following is a solution?8576
Answer:
8
Explanation:
Let the number = n
Twice the number decreased by 4:
[tex]2n-4[/tex]The phrase 'at least' means the expression above can either be equal to or greater than 12.
Thus, the given statement as inequality is:
[tex]2n-4\geq12[/tex]We then solve the inequality for n.
[tex]\begin{gathered} \text{ Add 4 to both sides} \\ 2n-4+4\geq12+4 \\ 2n\geq16 \\ \text{ Divide both sides by 2} \\ \frac{2n}{2}\geq\frac{16}{2} \\ n\geq8 \\ \implies n=(8,9,10,\cdots) \end{gathered}[/tex]The number that is a solution is 8.

Given the set of data:
5, 4, 16, 21, 10, 6, 15
Let's create a box-and-whisker plot from the given data.
The box and whisker plot has the following properties:
Let's solve for the following:
• Minimum value or lower extreme:
This is the smallest value in the data set.
Here, the minimum value is 4.
• Maximum value or upper extreme:
This is the greatest number in the data set.
Here, the greatest number is 21.
• Median:
This is the middle value after arranging the data in ascending order(from lowest to greatest).
Arranging in ascending order, we have:
4, 5, 6, 10, 15, 16, 21
The middle number above is = 10
Therefore the median is 10.
• Lower quartile:
The lower quartile is the median of the lower half of the data.
To find the lower quartile, let's list the lower half of data first.
Lower half:
4, 5, 6
The median of the lower half of the data is 5.
Therefore, the lower quartile is 5.
• Upper quartile:
The upper quartile is the median of the upper half of the data set.
Upper half of the data set:
15, 16, 21
The median is 16.
The upper quartile is 16.
Therefore the box and whisker plot created from the given data set is:

3.Six Flags charge and entrance fee per person and a fee per every ride that you get on. When 6 teachers went to Six Flags and rode on 20 rides total, they ended up paying $350. When 15 people went to Six Flags and rode on 47 rides they paid $900. Write an expression for this situation.
Answer:
Step-by-step explanation:
Expression:
y = mx + n*b
In which m is the cost per ride and b is the entrance fee.
y is the total cost, x is the number of rides and n is the number of people.
When 6 teachers went to Six Flags and rode on 20 rides total, they ended up paying $350.
This means that:
20m + 6b = 350
When 15 people went to Six Flags and rode on 47 rides they paid $900.
This means that:
47m + 15b = 900
Solving the system:
20m + 6b = 350
47m + 15b = 900
Multiplying the first equation by -5, the second by 2.
-100m - 30b = -1750
94m + 30b = 1800
-6m = 50

Mario loaned Juan $21,890 at an interest rate of 14% for 164 days. How much will juan pay Mario at the end of 164 days? Round youranswer to the nearest cent. Note: Assume 365 days in a year and 30 days in a month.
For the interest calculation we shall apply the simple interest formula which is;
[tex]\begin{gathered} I=P\times R\times T \\ \text{Where;} \\ P=\text{Initial amount borrowed} \\ R=\text{rate of interest (expressed as decimal)} \\ T=\text{Time in years} \end{gathered}[/tex]The initial amount is $21890, the rate is 14% (that is 0.14) and the time is 164/365 of a year.
Therefore, the interest calculated would be;
[tex]\begin{gathered} I=P\times R\times T \\ I=21890\times0.14\times\frac{164}{365} \\ I=3064.6\times\frac{164}{365} \\ I=1376.9709589 \\ I\approx1376.9\text{ (rounded to the nearest cent)} \end{gathered}[/tex]The interest payable at the end of 164 days is $1,376.90 (rounded to the nearest cent).
Therefore, the amount Juan would pay back is;

[tex]400^2\text{ + }300^2=D^2[/tex][tex]D\text{ = }\sqrt[]{400^2+300^2}[/tex][tex]D\text{ = 500 ft.}[/tex]Step 3: Finish the problem by plugging in numbers for every quantity in the equation

Answer
a) f(5) = 12
b) f(-1) = 6
c) f(-3) = 4
Explanation
We are given the function
f(x) = x + 7
We are then asked to evaluate a number of valus of x for the function
a) f(5)
f(x) = x + 7
f(5) = 5 + 7 = 12
b) f(-1)
f(x) = x + 7
f(-1) = -1 + 7 = 6
c) f(-3)
f(x) = x + 7
f(-3) = -3 + 7 = 4

So they can fill 16 containers.
1) If an art Teacher has
9 3/5 gallons
Each container holds
3/5 gallons
2) Firstly, let's turn that mixed number into an improper fraction
9 3/5 = (5 x 9+3) /5 = 48/5
Given that each container holds 3/5, then let's divide
48/5 ÷ 3/5 = 48/5 x 5/3 =16
If we hadn't turned
9 3/5 ÷ 3/5 = 16
3) So they can fill 16 containers.
