Order each group from least to greatest.
Answer:
(1) 5 , PI + 2, 17/3
(2) 3/2, sqrt (5), 2.5
(3) Sqrt(5)/2, PI – 2, 5/4
Step-by-step explanation:
For each number, begin by comparing the whole numbers. The one with the least whole number is the smallest while the one with the largest is the biggest number.
If the numbers being compared have the same whole numbers, check the decimal places. Begin with tenths. The one with the lowest number is the smallest number. If they are the same compare the hundredths, if they are the same compare thousandths...until you find a decimal that is different and can differentiate the numbers.

Answer:
Part 1) The perimeter of rectangle is equal to 24 units
Part 2) The area of rectangle is equal to 32 square units
Step-by-step explanation:
Part 1) Find the perimeter of rectangle
we know that
The perimeter of rectangle is equal to
[tex]P=2(L+W)[/tex]
where
L is the length of rectangle
W is the width of rectangle
we have
[tex]F(-2,5),R(-2,1),O(6,1),G(6,5)[/tex]
Plot the figure to better understand the problem
using a graphing tool
see the attached figure
Remember that in a rectangle opposite sides are congruent and the measure of each interior angle is equal to 90 degrees
so
[tex]FG=RO=L\\RF=OG=W[/tex]
the formula to calculate the distance between two points is equal to
[tex]d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}[/tex]
step 1
Find the distance FG
[tex]F(-2,5),G(6,5)[/tex]
substitute the values
[tex]d=\sqrt{(5-5)^{2}+(6+2)^{2}}[/tex]
[tex]d=\sqrt{(0)^{2}+(8)^{2}}[/tex]
[tex]FG=8\ units[/tex]
step 2
Find the distance RF
[tex]R(-2,1),F(-2,5)[/tex]
substitute the values
[tex]d=\sqrt{(5-1)^{2}+(-2+2)^{2}}[/tex]
[tex]d=\sqrt{(4)^{2}+(0)^{2}}[/tex]
[tex]RF=4\ units[/tex]
step 3
Find the perimeter
[tex]P=2(L+W)[/tex]
we have
[tex]FG=RO=L=8\ units\\RF=OG=W=4\ units[/tex]
substitute
[tex]P=2(8+4)=24\ units[/tex]
Part 2) Find the area of rectangle FROG
we know that
The area of rectangle is equal to
[tex]A=LW[/tex]
we have
[tex]FG=RO=L=8\ units\\RF=OG=W=4\ units[/tex]

[tex]A=(8)(4)=32\ units^2[/tex]
The area and the perimeter of the rectangle FROG is evaluated as:
Area(FROG) = [tex]32 \: \rm unit^2[/tex]Perimeter(FROG) = [tex]64\: \rm units[/tex]How to find the area and the perimeter of a rectangle?For a rectangle with length and width L and W units, we get:
Area of the rectangle = [tex]L \times W \: \rm unit^2[/tex]Perimeter of the rectangle = [tex]2(L + W) \: \rm unit^2[/tex]What is the distance between two points ( p,q) and (x,y)?The shortest distance(straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:
[tex]D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.[/tex]
The coordinates of the points of the rectangle FROG are given as:
F(-2,5), R(-2,1), G(6,5), and O(6,1) (from its plot, as given below)
FR and RO are length and width pair(we can call any one of them as length and other as width) of the considered rectangle as they are adjacent to each other.
We denote length of a line segment AB by |AB|
Thus, we get:
Length of the rectangle = |FR| = [tex]\sqrt{(-2-(-2))^2 + (1 - 5)^2 } = 4[/tex] unitsWidth of the rectangle = |RO| = [tex]\sqrt{(6-(-2))^2 + (1 - 1)^2 } = \sqrt{64} = 8 \: \rm units[/tex]Now with the help of length and width, we can evaluate its perimeter and area, as shown below:
Area(FROG) = [tex]L\times W = 4 \times 8= 32 \: \rm unit^2[/tex]Perimeter(FROG) = [tex]2(L + W) = 2(4 + 8) = 64\: \rm units[/tex]Learn more about distance between two points here:

which of the following is an even function
f(x) = 7 is a even function
Solution:
Given that we have to find the even function
A function is even if and only if f(–x) = f(x)
Steps to follow:
Replace x with -x and compare the result to f(x). If f(-x) = f(x), the function is even.
If f(-x) = - f(x), the function is odd.
If f(-x) ≠ f(x) and f(-x) ≠ -f(x), the function is neither even nor odd.
Option 1[tex]f(x) = (x - 1)^2[/tex]
Substitute x = -x in above function
[tex]f(-x) = (-x - 1)^2[/tex]
Thus [tex]f(-x) \neq f(x)[/tex]
So this is not a even function
Option 2f(x) = 8x
Substitute x = -x in above function
f(-x) = 8(-x) = -8x
Thus [tex]f(-x) \neq f(x)[/tex]
So this is not a even function
Option 3[tex]f(x) = x^2 - x[/tex]
Substitute x = -x in above function
[tex]f(-x) = (-x)^2 - (-x) = x^2 + x[/tex]
Thus [tex]f(-x) \neq f(x)[/tex]
So this is not a even function
Option 4f(x) = 7
f(-x) = 7
Thus f(-x) = f(x)
Thus it is a even function

Answer:
D
Step-by-step explanation:
Find (f + g)(x) then evaluate (f + g)(9)
(f + g)(x) = f(x) + g(x)
= 4x - 1 + x² - 2 = x² + 4x - 3
Now substitute x = 9 into the expression
(f + g)(9) = 9² + 4(9) - 3 = 81 + 36 - 3 = 114 → D
Answer:
J.117
Step-by-step explanation:
f(x) =4x-1
if f(2)= 4(2)-1
f(2)= 8-1 = 7
f(2) = 7 equation 1
g(x) =x2-2
if g(4)= (4)2-2
g(4) = 8-2 = 6 equation 2
Now,
(f+g)(9) =?
subtitute equation 1 and 2
(7+6)(9)=?
(13)(9)=?
13×9= 117

The median of given data is 42.5
And
The median after replacing 42 with 92 is 44.5
Step-by-step explanation:
A median is the middle value of the data that divided the data in two equal parts
Given data is:
46 43 39 48 52 40 42 98 20 38
First of all, the data has to arranged in ascending order
20, 38, 39, 40, 42, 43, 46, 48, 52, 98
As the number of values is even, n=10, the median will be the average of middle two numbers
20, 38, 39, 40, 42, 43, 46, 48, 52, 98
[tex]Median = \frac{42+43}{2}\\=\frac{85}{2}\\=42.5[/tex]
The median is 42.5
Now,
Replacing 42 with 92
20, 38, 39, 40, 92, 43, 46, 48, 52, 98
The data has to be re-arranged
So,
20, 38, 39, 40, 43, 46, 48, 52, 92, 98
As the number of values is same,
[tex]New\ median = \frac{43+46}{2}\\=\frac{89}{2}\\= 44.5[/tex]
Hence,
The median of given data is 42.5
And
The median after replacing 42 with 92 is 44.5

1. find a, b, and c
a = 1
b = -3
c = 1
2. plug values into formula
x = [3 ± sqrt(9-4•1•1)] / 2
3. simplify
x = [3 ± sqrt(5)] / 2
This is B.
Answer:
Option b) is correct
ie., [tex]x=\frac{3\pm \sqrt{5}}{2}[/tex]
Step-by-step explanation:
Given quadratic equation is [tex]x^{2}-3x+1=0[/tex]
To find the solutions of given equation:
Solution of quadratic equation [tex]ax^{2}+bx+c=0[/tex]
[tex]x=\frac{-b\pm \sqrt{b^{2}-4ac}}{2a}[/tex] where a,b, are coefficients of [tex]x^{2}[/tex] and x respectively and c is constant.
From the given quadratic equation a=1, b=-3 and c=1
[tex]x=\frac{-(-3)\pm \sqrt{(-3)^{2}-4(1)(1)}}{2(1)}[/tex]
[tex]x=\frac{3\pm \sqrt{9-4}}{2}[/tex]

Find the vertical asymptote(s) of f of x equals quantity 5 x squared plus 3x plus 6 end quantity over quantity x squared minus 100.
x = −5, 10
x = −10, 10
x = 5, −10
x = −5, 5
Answer:
x = 10 and x = -10
Step-by-step explanation:
Given the function
[tex]f(x)=\dfrac{5x^2+3x+6}{x^2-100}[/tex]
This function is undefied when the denominator equals to 0. Find these values for x:
[tex]x^2-100=0\\ \\(x-10)(x+10)=0\\ \\x-10=0\ \ \text{or}\ \ x+10=0\\ \\x=10\ \ \text{or}\ \ x=-10[/tex]
This means that vertical lines x = 10 and x = -10 are vertical asymptotes (the graph of the function f(x) cannot meet these lines because this function is undefined at x = 10 and x = -10)

If age is an explanatory variable and height is the corresponding response variable, which of these would be represented by the y - axis on a scatterplot?
Answer:
The height variable should be represented by the y-axis on a scatterplot.
Step-by-step explanation:
The explanatory variable and independent variable are similar terms. When a variable is not at all dependent on any factor then it is called an explanatory variable. So, it must be plotted along the independent axis i.e. x-axis.
On the other hand, a response variable is an alternate term of the dependent variable and in our case height is a corresponding dependent variable of explanatory variable age.
Therefore, the height variable should be represented by the y-axis on a scatterplot. (Answer)

Point (-2 , 4) lies in the 2nd quadrant
Point (3 , -1) lies in the 4th quadrant
Point (-1 , 0) lies on the negative part of the x-axis
Point (1 , 2) lies in the 1st quadrant
Point (-3 , -5) lies in the 3rd quadrant
Step-by-step explanation:
Let us revise the signs of the coordinates in each quadrant
x and y coordinates are positive in the 1st quadrantx-coordinate is negative and y-coordinate is positive in the 2nd quadrantx and y coordinates are negative in the 3rd quadrantx-coordinate is positive and y-coordinate is negative in the 4th quadrantThe general point on the positive part of x-axis is (x , 0), and on the negative part of x-axis is (-x , 0)The general point on the positive part of y-axis is (0 , y), and on the negative part of y-axis is (0 , -y)Now let us check the points
Point (-2 , 4) ⇒ red point
∵ x = -2 and y = 4
∵ x-coordinate is negative and y-coordinate is positive
∴ Point (-2 , 4) lies in the 2nd quadrant
Point (3 , -1) ⇒ blue point
∵ x = 3 and y = -1
∵ x-coordinate is positive and y-coordinate is negative
∴ Point (3 , -1) lies in the 4th quadrant
Point (-1 , 0) ⇒ green point
∵ x = -1 and y = 0
∵ x-coordinate is negative and y-coordinate is zero
∴ Point (-1 , 0) lies on the negative part of the x-axis
Point (1 , 2) ⇒ purple point
∵ x = 1 and y =2
∵ x and y coordinates are positive
∴ Point (1 , 2) lies in the 1st quadrant
Point (-3 , -5) ⇒ black point
∵ x = -3 and y = -5

i have three fractions (9/10, 2/3, 2/4), i know that the order from largest to smallest is 9/10, 2/3, 2/4, but how do i actually go about figuring out WHY its in that order without just looking at it or using graphs?
Step-by-step explanation:
To compare fractions, they need to have the same denominator. So you need to find the least common multiple (LCM) of 10, 3, and 4.
To find the LCM, first write the prime factorizations.
3 = 3
4 = 2²
10 = 2×5
The LCM is the product of each factor raised to its highest exponent.
LCM = 2²×3×5
LCM = 60
Now we rewrite each fraction with this new denominator.
9/10 = 54/60
2/3 = 40/60
2/4 = 30/60
Answer:
You need to convert the numbers into the same format.
Step-by-step explanation:
If you want to keep them in fraction form, you need to find the least common multiple. This means the smallest number that can be divided by all of the denominators. For this example, the number would be 60, because 60/10 is 6, 60/3 is 2, and 60/4 is 15. Now that we know this, you need to make every denominator 60. You do this by multiplying the numerator by whatever you needed to multiply the denominator by to get 60. For example, you need to multiply 10 by 6 to get sixty, so you would multiply 9 by 6 as well. You would repeat this pattern with all of the numbers, getting 54/60 (9/10), 40/60 (2/3), and 30/60 (2/4). This makes it very easy to tell which is the larger number.
If you don't want to do all of that, you can use decimal form. To find what each number would be in decimal form, divide the numerator by the denominator. For example, 9 divided by ten is .9, 2 divided by 3 is .66..., and 2/4 is .5.
-18u+16u-7=9 solve for u
-18u+16u-7=9
-2u - 7 = 9 (combine like terms)
-2u = 16 (add 7 on both sides)
u = -8
Answer:
The correct answer to this problem is u = -8.
Step-by-step explanation:
To solve this problem, we first must combine like terms on the left side of the equation. This means adding together the two terms that have a "u" multiplied by a number. To combine them, we simply add the coefficients together, as we would with constant values. This is modeled below:
-18u+16u-7=9
-2u - 7 = 9
Next, we want to add 7 to both sides of the equation. This will cancel out the -7 on the left side of the equation, isolating the term with the variable u (what we are trying to solve for).
-2u - 7 + 7 = 9 + 7
-2u = 16
Finally, we want to divide both sides by -2 in order to isolate the variable u. This will get rid of the coefficient of negative 2 and give us our answer.
u = 16/-2 = -8
Therefore, the answer to this question is u = -8.

5% tax on $1.50 What us total cost
Answer:
Step-by-step explanation:
In order to obtain the total amount that Monica was charged you should follow some steps.
How much was the net price? You can obtain this value either by clearing the x:
X * 5% = $1.50
X = $1.50 / 5%
Or by using simple rule of three:
If 5% is $1.50
Then 100% is X
So you obtain = $30
Now you just need to sum The net prices and the taxes
Net + tax = Total Charge
$30 + $1.5 = $31.5
Answer:
.08 cents rounded
Step-by-step explanation:
1.50x.05%=.075
What are the solutions to the equation
[tex]2 |x - 2| - 8 = 20[/tex]
The solutions of the equation are -12 and 16
Step-by-step explanation:
Absolute value describes the distance of a number on the number line from 0 without considering which direction from zero the number lies. The absolute value of a number is never negative, if IxI = a, where a > 0, then
x = ax = -a∵ 2Ix - 2I - 8 = 20
- At first add 8 to both sides
∴ 2Ix - 2I = 28
- Then divide both sides by 2
∴ Ix - 2I = 14
Now By using the notes above equate x - 2 by 14 and -14
∵ x - 2 = 14
- Add 2 to both sides
∴ x = 16
∵ x - 2 = -14
- Add 2 to both sides
∴ x = -12
The solutions of the equation are -12 and 16
