Which represents the restrictions on the radical inequality [tex]\sqrt[4]{2x+1} \ \textgreater \ 3[/tex]?
A. [tex]2x+1\geq 0[/tex]
B. [tex]\sqrt{2x+1} \ \textgreater \ 0[/tex]
C. [tex]2x+1\leq 0[/tex]
D. There are no restrictions.
there are no restrictions other than 2 x + 1 > 81 on the radical inequality.
We are given the radical inequality as:
⁴√ 2 x + 1 > 3
We need to find the restriction on this inequality.
For this we will first put x on one side and other constant on the other side.
So, we get that:
2 x + 1 > 3⁴
2 x + 1 > 81
So, the restriction is not from the given options.
But, the value of 2 x + 1 should be greater than 81 for the inequality to be true.
Therefore, we get that, there are no restrictions other than 2 x + 1 > 81 on the radical inequality.

There are 600 pipes in stock at Patty’s hardware store. She randomly selects 40 pipes and finds that 8 of the pipes are made of chrome. How many pipes in stock at her store can Patty predict are made of chrome?
The number of pipes that are made of chrome according to the prediction by Patty are 120.
It is given in the question that :-
Number of pipes in stock at Patty's hardware store = 600
Number if pipes randomly selected by Patty = 40
Number of pipes of chrome = 8
Hence, we can write,
Probability of chrome pipes = 8/40 = 1/5
Therefore, we can write,
Number of pipes that are made of chrome according to the prediction by Patty = (1/5)*600 = 120

a professor rolls a fair, six-sided die. using the classical method of probability, what is the probability that at least five spots will be showing up on the die?
The probability that at least five spots will be showing up on the die is 1/3.
It is given that a professor rolls a fair, six-sided die.
We need to find the probability that at least five spots will be showing up on the die.
Total possible outcomes = {1,2,3,4,5,6}
Number of total outcomes = 6
At least five spots will be showing up on the die. So,
Favorable outcomes = {5,6}
Number of favorable outcomes = 2
Formula for probability:
Probability = [tex]\frac{Number of Favorable Outcomes}{Number of Total Outcomes}[/tex]
On substituting Number of favorable outcomes and Number of total outcomes in the formula of Probability, we get
Probability = 2/6
Probability = 1/3
Therefore, the required probability is 1/3.

Answer:
subtract 2x from 3x thats x so 50=x
Step-by-step explanation:
Answer:x=50
Step-by-step explanation:bring 3x over on one side with 2x and bring 50 over on the other side by itself.
The equation becomes 2x-3x=-50
2x-3x is -x
so the equation is -x=-50
there are two negatives in the equation so you make the equation positive because a negative and a negative equals a positive

A solid glass cylinder, which is used in an expensive laser amplifier, has a volume of 75vm^3. The cost of polishing the surface area of this glass cylinder is £2 per cm² for the curved surface area and £3 per cm^2 for the circular top and base areas. Given that the radius of the cylinder is r cm, (a) show that the cost of the polishing, £C, is given by C = 6πr² + 300/r
The cost of the polishing, £C, is given by C = 6πr² + 300/r.
The volume of the solid cylinder is 75 m³.
Formula for volume of cylinder = πr²h.
Where R is rhe radius of cylinder and h is the height of the cylinder.
So we can write,
πr²h = 75
h = 75/πr².
So the height of the cylinder is 75/πr² centimeters.
Curved surface area of the cylinder is 2πrh m².
Cost of polishing the curved surface area is £2/cm².
Total cost of polishing the curved surface area = £2×2πrh
Area of the base and the top is 2(πr²).
Cost of polishing base and top is £3/cm².
Cost of polishing 1m² of the base and top,
Cost of area of base and top = £3/cm².
Total Cost of polishing base and top area = £3×2(πr²)
The total cost C of polishing the whole glass,
C = 4πrh + 6πr²
Puting the value of h = 75/πr²
C = 4πr(75/πr²) + 6πr²
C = 6πr² + 300/r.
Hence it is proved that the total cost of polishing is,
C = 6πr² + 300/r.

The perimeter of a college basketball court is 96 meters and the length is 14 meters more than the width. What are the dimensions?
The dimensions of the college basketball court with a perimeter of 96 meters are:
Length = 31 metersWidth = 17 meters.What are the dimensions of a perimeter?The dimensions of a rectangular perimeter, like a basketball court, are the two sides (length and width).
The perimeter of a rectangle measures the four sides, that is, the two long sides and two wide sides.
The perimeter is given by the perimeter equation, P = 2(a+b).
The perimeter of the basketball court = 96 meters
The perimeter = 2(Length + Width)
2(Length + Width) = 96 meters
Length = 14 meters more than the width
The total difference of the two lengths = 28 meters (14 x 2)
Width = 17 meters (96 - 28)/2
Length = 31 meters (17 + 14)
Check:
Perimeter = 2(Length + Width)
96 meters = 2(31 + 17)
96 = 62 + 34
96 = 96
Thus, the college basketball court with a perimeter of 96 meters has the following dimensions: 31 meters in length and 17 meters in width.

In a survey 34% of population was found to know hindi 46% to know english and 23% to know both languages.what is the percentage of those knowing neither hindi nor english.
We would find the percentage of those knowing neither Hindi nor English in the population using set theory,
Percentage of population knowing English (A) = 46%
Percentage of population knowing Hindi (B) = 34%
Percentage of population who know both languages (A U B) = 23%
therefore,
Applying set theory,
A U B = A + B - (A ∩ B)
23% = 36% + 46% - ( A ∩ B)
A ∩ B = 80% - 23% = 57% population knows either Hindi OR English.
So, Population who neither know Hindi or English = 100% - 57% = 43%

The area of a trapezoid is given by the formula A=12(b1+b2)h. Solve the equation for b2.
In a case whereby the area of a trapezoid is given by the formula A=12(b1+b2)h then the equation for b2 is b2= (A - 12hb1)/12h.
How can the value of the term b2 be expressed?
The formula for the trapezoidis given as A=12(b1+b2)h , where the value of term b2 is been exdpected to be found.
firstly, we need to open the bracket as :
A=12(b1+b2)h
A= 12hb1 + 12hb2
Then this can be simplified as 12hb2= (A - 12hb1)
Then we can try to make the b2 the subject of the formula as
b2= (A - 12hb1)/12h.
