Answer: 14, 17, 30
Step-by-step explanation:
In order to form a triangle, the sum of two sides must be GREATER than the third side for all combinations:
a + b > c & a + c > b & b + c > a
21 + 23 = 44 which is NOT greater than 44
2 + 3 = 5 which is NOT greater than 7
12 + 36 = 48 which is NOT greater than 53
14 + 17 > 30 & 14 + 30 > 17 & 17 + 30 > 14
so these side length form a triangle

Answer:
x = (3 − √5) / 2, (3 + √5) / 2, and 1
Step-by-step explanation:
Using rational root theorem, ±1 are possible roots. By trial and error, we find that +1 is a root. Therefore, x − 1 is a factor. Knowing this, we can use grouping or long division. Using grouping:
x⁴ − 5x³ + 8x² − 5x + 1 = 0
x⁴ − 5x³ + 4x² + 4x² − 5x + 1 = 0
x² (x² − 5x + 4) + 4x² − 5x + 1 = 0
x² (x − 4) (x − 1) + (4x − 1) (x − 1) = 0
(x² (x − 4) + 4x − 1) (x − 1) = 0
(x³ − 4x² + 4x − 1) (x − 1) = 0
Repeating the process, possible rational roots of x³ − 4x² + 4x − 1 are ±1. We already know -1 isn't a root. By trial and error, we find that +1 is again a root. Using grouping to factor:
(x³ − 4x² + 3x + x − 1) (x − 1) = 0
(x (x² − 4x + 3) + x − 1) (x − 1) = 0
(x (x − 3) (x − 1) + x − 1) (x − 1) = 0
(x (x − 3) + 1) (x − 1) (x − 1) = 0
(x² − 3x + 1) (x − 1)² = 0
To find the roots of x² − 3x + 1, we use the quadratic formula.
x = [ -(-3) ± √((-3)² − 4(1)(1)) ] / 2(1)
x = [ 3 ± √(9 − 4) ] / 2
x = (3 ± √5) / 2
So the roots are x = (3 − √5) / 2, (3 + √5) / 2, and 1.
Could I please have some help? Thanks
Answer:
D
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = - 1 [tex]\frac{1}{2}[/tex] -(- [tex]\frac{1}{2}[/tex] ) = - 1
d = - 2 [tex]\frac{1}{2}[/tex] - (- 1 [tex]\frac{1}{2}[/tex] ) = - 1
d = - 3 [tex]\frac{1}{2}[/tex] - (- 2 [tex]\frac{1}{2}[/tex] ) = - 1
This indicates the sequence is arithmetic with explicit formula
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - [tex]\frac{1}{2}[/tex] and d = - 1 , thus
[tex]a_{n}[/tex] = - [tex]\frac{1}{2}[/tex] - 1 (n - 1) = - [tex]\frac{1}{2}[/tex] - n + 1 = [tex]\frac{1}{2}[/tex] - n , where n = 1, 2, 3, 4, ......
what is 2 times 8/10???
So the right answer is 8/5
Look at the attached picture
Hope it will help you
Good luck on your assignment
Think of the 2 in this problem as 2/1.
So we have 2/1 × 8/10.
Now we can cross-cancel the 2 and 10 to 1 and 5.
So we have 1/1 × 8/5 which is 8/5.

Write the equation of the graph which is the reflection of y=−|x−1|−1 about the origin
Answer:
f(x) = |x + 1| + 1
Step-by-step explanation:
A reflection over the y-axis followed by a reflection over x-axis is equivalent to a reflection about origin.
f(x) = -|x-1| -1
reflection over the x-axis:
-f(x) = (-1)*(-|x-1| -1) = |x-1| +1
reflection over the y-axis of the previous function:
-f(-x) = |-x-1| +1 = |x + 1| + 1
which is the reflection of f(x) about the origin
Three times a number, X, increased by four is equal to five times the number, x. Which equation can be used to solve for x
3x+ 5x=4
3x4.5
3x4+5
3-4-5
Answer:
Step-by-step explanation:
Three times a number x : 3x
Three times a number x increase by 4: 3x +4
Five times the number x: 5x
5x = 3x +4
Subtract 3x from both the sides.
5x - 3x = 3x +4 - 3x
2x = 4
Divide both sides by 2
2x/2 = 4/2
x=2
The number is 2

To rationalize the denominator of [tex]\frac{2\sqrt{10} }{3\sqrt{11} }[/tex] you should multiply the expression by [tex]\frac{\sqrt{11} }{\sqrt{11} }[/tex]
Given the surd function:
[tex]\frac{2\sqrt{10} }{3\sqrt{11} }[/tex]Rationalizing surd functions means multiplying the numerator and denominator of such function by the conjugate of the denominator.For the surd function given, to rationalize it, we only need to multiply the numerator and denominator by √11 as shown:
[tex]=\frac{2\sqrt{10} }{3\sqrt{11} }\times \frac{\sqrt{11} }{\sqrt{11} } \\=\frac{2\sqrt{110}}{3(11)}\\= \frac{2\sqrt{110}}{33}\\[/tex]

The following graph represents the hourly commission of a home appliance salesperson, y, based on the number of salespeople that are
working the showroom floor, x. The graph of the hourly commission of the salesperson is a quadratic function. What is the equation for
the function in standard form if the vertex is 6.5,42.25 and the origin is the only other known point?
We have been given graph of a downward opening parabola with vertex at point [tex](6.5,42.25)[/tex]. We are asked to write equation of the parabola in standard form.
We know that equation of parabola in standard form is [tex]f(x)=ax^2+bx+c[/tex].
We will write our equation in vertex form and then convert it into standard form.
Vertex for of parabola is [tex]y=a(x-h)^2+k[/tex], where point (h,k) represents vertex of parabola and a represents leading coefficient.
Since our parabola is downward opening so leading coefficient will be negative.
Upon substituting coordinates of vertex and point (0,0) in vertex form, we will get:
[tex]0=-a(0-6.5)^2+42.25[/tex]
[tex]0=-a(42.25)+42.25[/tex]
[tex]-42.25=-a(42.25)+42.25-42.25[/tex]
[tex]-42.25=-42.25a[/tex]
[tex]a=1[/tex] Divide both sides by [tex]-42.25[/tex]
So our equation in vertex form would be [tex]f(x)=-(x-6.5)^2+42.25[/tex].
Let us convert it in standard from.
[tex]f(x)=-(x^2-13x+42.25)+42.25[/tex]
[tex]f(x)=-x^2+13x-42.25+42.25[/tex]
[tex]f(x)=-x^2+13x[/tex]
Therefore, the equation of function is standard form would be [tex]f(x)=-x^2+13x[/tex].

When the maximum value in a data set is exchanged for a higher
number, does it change any of the other numbers in the five-number
summary?
Answer:
It doesn't change any of the other numbers of the five number summary. Only the maximum value of the data set changes, out of the five number summary of the data set.
Step-by-step explanation:
The five number summary of any data set consists of five values which includes
- The maximum value of the data set.
- The minimum values.
- The lower quartile.
- The upper quartile.
- The median.
These values are usually presented together and ordered from lowest to highest: minimum value, lower quartile (Q1), median value (Q2), upper quartile (Q3), maximum value.
Replacing the maximum value with a higher number doesn't change any of the other five number summary as they all position markers, whose values do not change because of changes at one end of the distribution as the positions of the other variables n the dataset are untouched.
This means that, of the five number summary, only the maximum value of the data set changes.
Although, values like the range, mean and standard deviation also change too.
Hope this Helps!!!
There is no change in any of the other numbers of the five number summary.
Only the maximum value of the data set is changed.
Data set of numbers :The five number summary of any data set consists of five values which includes
Maximum value of the data set. Minimum values. Lower quartile. Upper quartile. Median.The median divides the data into a lower half and an upper half.

Answer:
The difference of 12.4 and a quotient of and a number because when it says quotient it is talking about division and you are not dividing anything.
Step-by-step explanation:
"The difference of 12.4 and a quotient of and a number" is not a translation of the algebraic expression.
What is an expression?One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.
Given:
An algebraic expression 12.4 - 36.
The equivalent expressions are:
1). 12.4 minus 3 times a number 6.
Let a = 6
That means, 12.4 - 3(6)
2). The product of 3 and a number subtracted from 12.4.
Let a = 6
That means, 12.4 - 3(6)
3). The difference of 12.4 and a quotient of and a number.
That means,
12.4 - 3/6
4). The difference of 12.4 and 3 times a number.
Let a = 6
