Sam entered three functions into a graphing calculator, y1 = x + 2, y2 = x2 + 2, and y3 = 2x. A portion of the table created by those functions is shown below.
Answers
y1 = x + 2
y2 = x ^ 2 + 2
y3 = 2 ^ x
For x = 0:
y1 = 0 + 2 = 2
y2 = 0 ^ 2 + 2 = 0 + 2 = 2
y1 = y2
For x = 5
y2 = 5 ^ 2 + 2 = 25 + 2 = 27
y3 = 2 ^ 5 = 32
y3> y2
For x = -1:
y1 = -1 + 2 = 1
y2 = (-1) ^ 2 + 2 = 1 + 2 = 3
y3 = 2 ^ (- 1) = 1/2 = 0.5
y3 <y1 <y2
Answer:
y1 = y2

What is Ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
let the ratio of students who walk to students who take bus = 5: 7
let the common ratio be x.
So, Number of students who walk = 5x
and, Number of students who Bus= 7x
Total students= 420
So, 5x+ 7x = 420
12x= 420
x= 35
Hence, students walk to school =5 x 35 = 175.

Factor completely a2 - 9a + 20

You can check, the numbers add up, because -5 - 4 is 9, and 5 * 4 is 20
a^2-9a+20=a(a^2/a-5a/a)+(-4)(-4a/(-4)+20/(-4))
a^2-9a+20=a(a-5)-4(a-5)
a^2-9a+20=(a-5)[a(a-5)/(a-5)-4(a-5)/(a-5)]

# 14. Q. find the area of rectangle
Answers
You must multiply the height and the width.
8 x 14 = 112
Area = Length x Width
From figure we can see,
Length = 14 ft
Width = 8 ft
So, Area = 14 x 8 = 112 ft²
Thus, the option third gives the correct measure of Area for given rectangle

The formula is [f(-1)-f(-4)]/[3]
The value of f(-1) is 3
The value of f(-4) is -3
The average rate of change is 2
==============================================
Explanation:
For the first blank, we use the formula
[ f(b) - f(a) ]/[ b - a ]
where 'a' and 'b' are the endpoints for the x interval
In this case, a = -4 and b = -1. When you plug those values into the formula above, you get...
[ f(b) - f(a) ]/[ b - a]
[ f(-1) - f(-4)]/[ -1 - (-4) ]
[ f(-1) - f(-4)]/[ -1+4 ]
[ f(-1) - f(-4)]/[ 3 ]
which is why the answer is choice C for the first blank
-------------------------------------------
To compute the value of f(-1), we draw a vertical line through -1 on the x axis. This vertical line crosses the diagonal function graph at the point (-1,3). The y value of this point is what we want. Plugging in x = -1 leads to y = 3. This is why f(-1) = 3
If you want, you can draw a horizontal line through (-1,3) and you'll see it touching 3 on the y axis.
-------------------------------------------
Follow similar steps as above to compute f(-4). Draw a vertical line through x = -4 on the x axis. Mark the point where the vertical line crosses the diagonal line. This point is (-4,-3). Optionally draw a horizontal line over til you hit the y axis and you'll find that y = -3 corresponds to x = -4
This is why f(-4) = -3
-------------------------------------------
We'll use the last three sections to compute the average rate of change. Everything combines together building up to this moment.
From the first part, we had the formula
[ f(b) - f(a) ]/[ b - a ]
[ f(-1) - f(-4)]/[ 3 ]
We can replace the "f(-1)" with 3 since we found that f(-1) = 3
Similarly, f(-4) = -3 so we can replace the "f(-4)" with -3
Doing those replacements and simplifying leads to...
[ f(-1) - f(-4)]/[ 3 ]
[ 3 - (-3)]/[ 3 ]
[ 3 + 3]/[ 3 ]
6/3
2
So the average rate of change is 2
Note: because the entire graph is a straight line, the average rate of change for any interval a < x < b is going to be equal to the slope m. In this case, the slope of the line is m = 2/1 = 2. We move up 2 units each time we move to the right 1 unit along the diagonal line.

Answers
x ⇒⇒⇒ number of times app is opened
$20 per month and an additional $0.005 each time the app is opened
∴ y = 0.005 x + 20
The attached figure represents the graph of y
Answer:
See attached diagram
Step-by-step explanation:
Let x be the number of times the app is opened and y be your monthly income (in dollars).
If an advertiser pays you $0.005 each time the app is opened, then he pays you $0.005x for all times the app is opened. Since an advertiser pays you $20 per month, then the total income is
y=20+0.005x.

Now your equation should be \frac{ \sqrt{6x^{6}y^{5} } }{ \sqrt{5} }
Then you should simplify your radical,
there are 3 groups of 2 in the x variables and 2 groups of 2 in the y variables, as a result, the x and y go outside the square root, and one y variable remains in the root (as there wasn't enough y's to make another group of 2) this should be over 5

Find the dimensions of a rectangle with an area of 100 square feet that has the minimum perimeter.
Answers
The side length of the square with an area of 100 ft² is √(100 ft²) = 10 ft.
The rectangle with the minimum perimeter for an area of 100 ft² is 10 ft by 10 ft.
The rectangle with an area of 100 square feet that has the minimum perimeter is a square with sides of 10 feet each.
Explanation:To find the dimensions of a rectangle with a particular area that has the minimum perimeter, the rectangle should be a square. This is because squares minimize perimeter for a fixed area.
Given the area of the rectangle (square in this case), which is 100 square feet, the sides would be the square root of the area. Therefore, in this case, the length and the width of the rectangle (also known as the dimensions) are both √100 = 10 feet.Hence, the rectangle with an area of 100 square feet and minimum perimeter is a square with side lengths of 10 feet.

During a basketball game a player makes 12 of 18 free throws attempted write the ratio as fraction reduced to the lowest term
Answers
Final answer:
The ratio of free throws made to free throws attempted by the player is 12/18, which can be reduced to its lowest terms by dividing both numbers by their greatest common divisor, 6, resulting in the reduced fraction 2/3.
Explanation:
To find the ratio of free throws made to free throws attempted, we start by looking at the numbers given: 12 made out of 18 attempted. We express this ratio as a fraction 12/18.
To reduce this fraction to its lowest terms, we need to find the greatest common divisor (GCD) that divides both numerator and denominator evenly.
In this case, the number 6 is the GCD of 12 and 18. Dividing both the numerator and the denominator by 6, we get 2/3.
Hence, the ratio of free throws made to free throws attempted, reduced to the lowest term, is 2/3.

Gwen - Two booksHenry - Four books.To derive the number of children who read fewer books than Carlos, we only need to count the number of people whose books are less than four.
Using the picture graph key, we know that:
Ryan read 4 books
Gwen = 2
Anna = 6
Henry = 3
Since 2 and 3 are less than 4 which was read by Carlos, then the number of children who read fewer books than Carlos are two in number.
