If x is greater than 0, what is the difference of 6x√14x - 5√56x^3 in simplest radical form?
Answer:
6x√14x - 5√56x^3 = -4√14x√x
I hope this helps at least. :)
Simply put, expressing a radical in its lowest extreme form implies simplifying it and that there are no more squared roots, cube roots, 4th roots, and so on to find. This also entails eliminating any radical from a fraction's base, and further calculation can be defined as follows:
Given:
[tex]\to \bold{6x\sqrt{14x} - 5\sqrt{56x^3}}[/tex]
To find:
simplest radical form=?
Solution:
[tex]\to \bold{6x\sqrt{14x} - 5\sqrt{56x^3}}[/tex]
[tex]\to \bold{6x\sqrt{14x} - 5 \sqrt{4 \times 14 \times x \times x \times x}}\\\\\to \bold{6x\sqrt{14x} - 5 \times 2x \sqrt{ 14 x}}\\\\\to \bold{6x\sqrt{14x} -10x \sqrt{ 14 x}}\\\\\to \bold{\sqrt{14x} (6x-10x)}\\\\\to \bold{\sqrt{14x} (-4x)}\\\\\to \bold{-4x\sqrt{14x} }\\\\[/tex]

What is the explicit rule for this geometric sequence?
2/9,2/3,2,6,...
an=3(29)n−1
an=3(29)n
an=29⋅3n−1
an=29⋅3n
Answer:
Tn = 2/3^(n-1)
Step-by-step explanation:
The nth term of a geometric progression is expressed as
Tn = ar^{n-1}
a is the first term
n is the number of terms
r is t common ratio
From the sequence
a = 2/9
r = (2/3)/(2/9) = 2/(2/3) =3
Substitute
Tn = 2/9(3)^(n-1)
Tn = 2/3^(n-1)
Hence the required equation is Tn = 2/3^(n-1)
Answer:
the actual answer is [tex]a_{n}[/tex][tex]=(\frac{2}{9} )3^{n-1}[/tex]

Solve for 'p'. Show all work: 2(-4x + 8) ≤ 20
Answer: Answer: x≥ −1 /2
Step-by-step explanation:
Answer:
x ≥ -1/2 or x ∈ [-1/2, +∞)
Step-by-step explanation:
2(-4x + 8) ≤ 20
divide both sides by 2
-4x + 8 ≤ 10
move 8 to the right
-4x ≤ 10-8
-4x ≤ 2
divide both sides by -4. Flip the sign since a negative value is being divided
x ≥ - 1/2

- 3x - 10 = 32
X = 14
X = -14
X = -10
x =10
Answer: -14
Step-by-step explanation:
-3x-10=32
Since the 10 is negative you have to add 10 on the right side of the equal sign. you add 10 to the negative 10 and it cancels out and becomes zero. Then you have to add 10 to the 32 and it becomes 42. Divide the 42 by negative 3 and you get -14.

1. If the diameter of a circular object is 10 feet. Find the radius and the circumference. Use 3.14 for π.
2. Find the perimeter of the window. R = 4ft
Answer:
1.
[tex]Radius = 5ft[/tex]
[tex]Circumference = 31.4\ ft[/tex]
2.
[tex]Perimeter = 25.12\ ft[/tex]
Step-by-step explanation:
Solving (1):
Given
[tex]Diameter = 10ft[/tex]
Required
Determine the radius and circumference
Radius is calculated as follows:
[tex]Radius = \frac{1}{2} * Diameter[/tex]
[tex]Radius = \frac{1}{2} * 10ft[/tex]
[tex]Radius = 5ft[/tex]
The circumference is calculated using:
[tex]Circumference = 2 * \pi * Radius[/tex]
[tex]Circumference = 2 * 3.14 * 5ft[/tex]
[tex]Circumference = 31.4\ ft[/tex]
Solving (2):
Given
[tex]R = 4ft[/tex]
Assume that the window is circular, the perimeter is calculated as follows:
[tex]Perimeter = 2 * \pi * R[/tex]
[tex]Perimeter = 2 * 3.14 * 4ft[/tex]
[tex]Perimeter = 25.12\ ft[/tex]

Answer:
m < [tex]\frac{36}{31}[/tex]
Rearrange:
Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :
-7+5*(9*m-7)-(9*m-2-9)<0
Step by step solution :
STEP 1
:
Equation at the end of step 1
(-7 + 5 • (9m - 7)) - (9m - 11) < 0
STEP 2
:
Equation at the end of step 2
36m - 31 < 0
STEP 3:
3.1 Divide both sides by 36
m-(31/36) < 0
Solve Basic Inequality :
3.2 Add 31/36 to both sides
m < [tex]\frac{31}{36}[/tex]

Eve is organizing a race to raise money for a local children's hospital. She makes $20 for each 5K participant and $45 for each 10K participant. Her goal is to raise $9,500.If x represents the number of participants in the 5K race and y represents the number of participants in the 10K race, the linear equation for the given scenario is
Answer:
20x + 45y = 9500 is the linear equation for given scenario
Step-by-step explanation:
Given that Eve makes $20 for each 5K participant and $45 for each 10K participant
Cost of each 5k participant = $ 20
Cost of each 10k participant = $ 45
Her goal is to raise $9,500
Let "x" represents the number of participants in the 5K race
Let "y" represents the number of participants in the 10K race
To find: linear equation for given scenario
The standard form for linear equations in two variables is Ax + By = C
Eve makes $20 for each 5K participant and $45 for each 10K participant and goal is to raise $ 9500
From the above statement, we can frame a equation as:
number of participants in the 5K race x Cost of each 5k participant + number of participants in the 10K race x Cost of each 10k participant = $ 9500
20x + 45y = 9500
Therefore, the linear equation for given scenario is found
Answer:
20x + 45y = 9500
yes/no: no
Solution:
Given that Eve makes $20 for each 5K participant and $45 for each 10K participant
Cost of each 5k participant = $ 20
Cost of each 10k participant = $ 45
Her goal is to raise $9,500
Let "x" represents the number of participants in the 5K race
Let "y" represents the number of participants in the 10K race
To find: linear equation for given scenario
The standard form for linear equations in two variables is Ax + By = C
Eve makes $20 for each 5K participant and $45 for each 10K participant and goal is to raise $ 9500
From the above statement, we can frame a equation as:
number of participants in the 5K race x Cost of each 5k participant + number of participants in the 10K race x Cost of each 10k participant = $ 9500
20x + 45y = 9500
If eve raises exactly $9,500, it is NOT possible for there to be 220 participants in the 5K race.

Answer:
The answer is D. and E.
Step-by-step explanation:
The answer is D and E because 10 multiplied by 2 is 20 and 20 is bigger then 12 and 10 times 3 is 30 which is also bigger than 12.

From the region (2, ∞) of the inequality the values -1, 0, and 2 are not in the region, but the value 3 is in the region so p = 3 is the solution to the inequality option (E) is correct.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than, known as inequality.
We have inequality:
10p - 8 >12
10p > 12 + 8
10p > 20
p > 2
p ∈ (2, ∞)
Thus, from the region (2, ∞) of the inequality the values -1, 0, and 2 are not in the region, but the value 3 is in the region so p = 3 is the solution to the inequality option (E) is correct.
