Answer: 0.20588235294 or ≈0.21
Step-by-step explanation: First, we should change the 7/10 into a fraction. (Divide numerator by the denominator) You should get .7 or 0.7. Then, when dividing, it would be 0.7 divided by 3.4 and I got 0.20588235294. I rounded it to the nearest hundredth to get ≈0.21. I hope this helped! Please, mark brainliest! (If can)
Let f(x)=\sqrt(3x-9) and g(x)=3x^(2)-9
A) what is the inverse of function f?
b) is f an inverse of g? Please show all work
A) The inverse of f(x) is f⁻¹(x) = (x² + 9)/3 and B) f is not an inverse of g.
What is an inverse function?First to be an inverse function that function needs to one to one function, meaning every different preimage must correspond to a different image.
We can obtain the inverse of a function by switching the variables x and y with their respective positions and solving for y in terms of x.
Given, f(x) = [tex]\sqrt{3x - 9}[/tex].
y = [tex]\sqrt{3x - 9}[/tex].
y² = 3x - 9.
3x = y² + 9.
x = (y² + 9)/3.
y = (x² + 9)/3.
f⁻¹(x) = (x² + 9)/3 and g(x) = 3x² - 9, so f is not an inverse of g.

The disadvantage of piece rate pay is that the cost of producing higher quantities of a product can be a reduction in the quality of the items produced.
What is piece rate?Piece rate is any type of job in which a worker is paid a set amount for each unit produced or action performed, regardless of time. Some employees may be paid on a piece rate or on a commission basis.
Employees are paid on a piece rate, and commission payments are based on results rather than an hourly or weekly pay rate. This means that the employee's weekly pay will vary depending on how much work they do. One of the drawbacks of piece rate pay is that the cost of producing larger quantities of a product may result in a decrease in the quality of the items produced.

Karen sold 15 hand-made bracelets, earning a total profit of $71.25. She plans to make 25 bracelets for her city’s arts and crafts market. If she sells all 25 bracelets, how much profit can Karen expect to earn?
Answer: $118.75
Step-by-step explanation: first to see how much one bracelet is, you have to do 71.25/15=4.75. one bracelet is $4.75. so now we multiply 4.75 by 25 to see how much 25 bracelets cost. 4.75x25=118.75. so, if Karen seems all of her bracelets, she can expect to make $118.75.

The probability of choosing red ribbon on both Monday and Tuesday is 1/4.
What is the probability?
The Probability in mathematics is possibility of an event in time. In simple words how many times that incident is happening in any given time interval.
Given that each morning Tess chooses either red ribbon or blue ribbon at random to wear in her hair.
That means probability of choosing between blue or red is 1/2 in one morning.
Now the probability of choosing red ribbon on both Monday and Tuesday,
1/2 × 1/2
= 1/4

The equation of the given function is y = -1/3 x. By using the points through which the line passing through, we can find its equation. Option A is correct.
What is the formula for finding the equation of a line passing through two points?The equation of the line passing through two points such as (x1, y1) and (x2, y2) is
y - y1 = [(y2 - y1)/(x2 - x1)] × (x - x1)
Calculation:From the given graph, the line is passing through the points (0, 0), (-3, 1), and (3, -1).
The equation of the line passing through (-3, 1) and (3, -1) is
y - y1 = [(y2 - y1)/(x2 - x1)] × (x - x1)
⇒ y - 1 = (-1 - 1)/(3 + 3) × (x + 3)
⇒ y - 1 = -2/6 (x + 3)
⇒ y - 1 = -1/3 (x + 3)
⇒ 3y - 3 = -x - 3
⇒ 3y = -x
⇒ y = -1/3 x
So, option A is correct.

The zeroes of the expression f(x) = 2x³ + 4x² - 8x - 16 are (x-2), (x+2) and (x+2). And multiplicity of x = -2 is 2.
What is Cubic equation?
Cubic equations are polynomials of degree3. That means the maximum degree of polynomial is three.
And the standard form of cubic equation is;
f(x) = ax³ + bx² +cx +d, where a, b, c and d are constant coefficients a ≠ 0.
Given that the expression
f(x) = 2x³ + 4x² - 8x - 16
Now we find the roots or zeroes of equation;
for that we will try hit and trial method,
let x = 2
f(x) = 2 (8) - 4 (4) - 8(2) -16
f(x) = 0
That means (x-2) is one of roots of cubic equation.
Now to find other roots of the cubic equation, we will simplify the cubic expression
f(x) = 2x² (x-2) + 8x (x-2) + 8 (x-2)
f(x) = (x-2) (2x²+ 8x + 8)
Now we will find the roots of quadratic equation (2x²+ 8x + 8).
let g(x) = (2x²+ 8x + 8).
factors of quadratic equation is (x+2) and (x+2).
Therefore the zeroes of the expression f(x) = 2x³ + 4x² - 8x - 16 are (x-2), (x+2) and (x+2). And multiplicity of x = -2 is 2.

What is triangle ?
A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.
A triangle is a 3-sided polygon that is occasionally (though not frequently) referred to as the trigon. There are three sides and three angles in every triangle, some of which may be the same.
AC and BD bisects one another
AE = CE --- Side
and
BE = DE --- Side
When both lines bisect one another, they form a pair of vertical angles and
When we apply the theorem of vertical angles to this, we have that:
∠AEB = ∠CED --- Angle
At this point, we have established:
Two sides of ABE and CDE are congruent and One angle in each of ABE and CDE are also congruent

The length and width of two sides of a rectangle are consecutive odd integers. The area of the rectangle is 143 square units.
Find the dimensions of the rectangle.
The width of the rectangle is blank and length is blank
The dimensions of the rectangle are 70.5 by 72.5 units.
What is a dimension?
A length measurement that only goes one way. Dimensions include things like width, depth, and height. One dimension is that of a line, two dimensions are found in a square, three dimensions are found in a cube, and one dimension is that of something's height, length, or width. For instance, the room is 26 feet by 15 feet in size.
Solution Explained:
Given,
Area = 143 unit^2
A/Q,
Let length be x and width be x + 2.
So, Area = l X w
143 = x + x + 2
143 = 2x + 2
x = (143 - 2)/2
x = 70.5
So width = x + 2 = 70.5 + 2 = 72.5
So, the dimensions are 70.5 by 72.5

The admission fee at the museum is 8.50 for children and 12.50 for adults on a certain day, a total of 240 people entered the museum and 2400$ was collected.
Use the variable c to represent children and the variable a to represent the adult
Answer:
Below
Step-by-step explanation:
a + c = 240 re-arrange to c = 240-a
revenue from child tix = 8.50 ( 240-a)
revenue from adult tix = 12.50 a summed, the revenues = 2400
8.5(240-a) + 12.5 a = 2400
2040 - 8.5 a + 12.5 a = 2400
4.5 a = 360
a = 80 tix then c = 240 - a = 160 tix

The inverse of f(x) = ∛5x + 5 is f⁻¹ = ( x³ - 5 ) / 5
What is inverse of function?
To find the inverse of a function, write the function y as a function of x i.e. y = f(x) and then solve for x as a function of y.An inverse function is a function that undoes the action of the another function. A function g is the inverse of a function f if whenever y=f(x) then x=g(y).Change y in for the f(x) :
y = ∛5x + 5
Switch the x and y
x³ = 5y + 5
x³ - 5 = 5y
y = ( x³ - 5 ) / 5
f⁻¹ = ( x³ - 5 ) / 5
Hence, The inverse of f(x) = ∛5x + 5 is f⁻¹ = ( x³ - 5 ) / 5

The probability is the first and the second case will be 0.625 and 0.3683, respectively.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.
Then the probability is given as,
P = (Favorable event) / (Total event)
A pack contains five white balls and three torpedoes. You want to draw two white balls.
Total events = 5 + 3
Total events = 8
You all the while drawing two balls aimlessly. Then the probability that they are both white is given as,
P = 5 / 8
P = 0.625
You all the while drawing two balls aimlessly. Whenever you have drawn two balls, you set back any debases, and redraw with the goal that you again have two drawn balls. Then the probability is given as,
P = [(3/8) x (5/8)] + [(3/8) x (5/8) x (4/7)]
