The solution of the equation for g is (m+n^2)/5M. The solution has been obtained by solving the given equation for g.
What is an equation?
A mathematical definition of an equation is a claim that two expressions are equal and joined by the equals sign "=". The two expressions need not be completely of variables i.e. one expression may contain variable and the other may not contain a variable.
We are given g: m+n^2 = g.5M
⇒m+n^2 = g.5M
⇒m+n^2 = 5gM
⇒5gM = m+n^2
⇒5gM/5M = (m+n^2)/5M .... (Dividing both sides by 5M)
⇒g = (m+n^2)/5M
Hence, the solution of the equation for g is (m+n^2)/5M.

The domain is discrete and the range is continuous, which can be an accurate statement regarding the two terms.
What are domain and range?The range of values that we are permitted to enter into our function is known as the domain of a function.
The x values for a function like f make up this set (x).
A function's range is the collection of values it can take as input.
After we enter an x value, the function outputs this sequence of values.
So, the parameters are as follows, taken from the query:
Downloaded Amount = $2.50
Added amount to each player = $1.50
Use x to indicate how many players there are.
The following representations are what we have.
Total amount = Amount to download + Amount to add each player * Number of players
Now, we obtain:
y = 2.50 + 1.50 * x
y = 2.50 + 1.5x
The number of players serves as the input to the aforementioned linear function.
The domain is discrete as a result.
The amount, though, can have decimal points

In the lab, Linda has two solutions that contain alcohol and is mixing them with each other. Solution A is 50% alcohol and Solution B is 10% alcohol. She us
400 milliliters of Solution A. How many milliliters of Solution B does she use, if the resulting mixture is a 20% alcohol solution?
We can start by using the concept of percentage concentration, which states that the percentage of alcohol in a solution is equal to the number of milliliters of alcohol in the solution divided by the number of milliliters of the solution, multiplied by 100.
Let's call the number of milliliters of Solution B that Linda uses x.
We know that:
Solution A is 50% alcohol, so it contains 50/100 = 0.5 = 1/2 of alcohol.
Solution B is 10% alcohol, so it contains 10/100 = 0.1 = 1/10 of alcohol.
The resulting mixture is a 20% alcohol solution.
Linda uses 400 milliliters of Solution A.
We can set up an equation using the percentage concentration concept and the information provided:
(400 * 1/2) + (x * 1/10) = (x + 400) * (20/100)
Solving for x:
200 + x/10 = (x + 400) * 0.2
x/10 = (x + 400) * 0.2 - 200
x/10 = x * 0.2 + 80
9x/10 = x * 0.2 + 80
9x = x*2 + 800
x = 800/8 = 100
So, Linda uses 100 milliliters of Solution B to make the resulting mixture a 20% alcohol solution.
A group of 12 people on a trek have enough water to last 8 days.
a) If 4 more people join the trek, how long will the water supply last the
whole group?
When the number of people is 16, the water lasts for 6 days, which is found using unitary method.
What is the unitary method?
The unitary method is a strategy for problem-solving that involves first determining the value of a single unit and then multiplying that value to determine the required value.
a) Let the amount of water present = L
Initially, this amount was considered for 12 people for 8 days.
For 12 people,
8 days = L
1 day = L/8
So the water required for one person for one day = (L/8) / 12 = L/96
But now 4 more people joined the trek,
So for 16 people, water used in one day = (L/96)*16 = L/6
Now the water will last for 6 days since,
(L/6 * 6) = L
b) The assumption that is made while solving the question is that the water required by each person is considered the same(L/96) even if the number of persons increases.
Therefore the water lasts for 6 days when the whole group consists of 16 people.

(a)​ [1,5]
​(b) ​[1,4​]
​(c)​ [1,3​]
​(d) ​[1, 1​+h] where h > 0 is any real number.
(a) Average velocity = -7(5^2-1^2) + 70(5-1) = -90 m/s.
(b) Average velocity = -7(4^2-1^2) + 70(4-1) = -62 m/s.
(c) Average velocity = -7(3^2-1^2) + 70(3-1) = -34 m/s.
(d) Average velocity = -7(1+h)^2 + 70(1+h-1) = -7h^2 + 70h m/s.
(a) Average velocity = -7(5^2-1^2) + 70(5-1) = -7(25-1) + 70(4) = -7*24 + 280 = -168 + 280 = -88 m/s.
(b) Average velocity = -7(4^2-1^2) + 70(4-1) = -7(16-1) + 70(3) = -7*15 + 210 = -105 + 210 = -95 m/s.
(c) Average velocity = -7(3^2-1^2) + 70(3-1) = -7(9-1) + 70(2) = -7*8 + 140 = -56 + 140 = -16 m/s.
(d) Average velocity = -7(1+h)^2 + 70(1+h-1) = -7(1+h)^2 + 70h = -7(1+h)^2 + 70h m/s. The average velocity of an object over a given period of time is calculated by taking the difference between the final and initial positions, and dividing it by the amount of time elapsed. In this exercise, we are given the position of an object along a line as a function of time, s(t) = -7t^2 + 70t. To solve each part, we can plug in the given time intervals into the function, and calculate the difference between the initial and final positions. We then divide this difference by the amount of time elapsed to find the average velocity. For example, in part (a), the average velocity is calculated as -7(5^2-1^2) + 70(5-1) = -90 m/s. In part (b), the average velocity is calculated as -7(4^2-1^2) + 70(4-1) = -62 m/s. In part (c), the average velocity is calculated as -7(3^2-1^2) + 70(3-1) = -34 m/s.

b) Prabin types 765 words in 9 minutes. How many words would he type in half an hour? How long does he take to type 12,750 words at the same speed?
Answer:
Prabin types 765/9 i.e, 85 words in one minute. Therefore in 30 minutes prabin will type 30 x 85 i.e., 2550 words. Again, he types 1 word in 9/765 minutes. Therefore , he will type 12750 words in 12750 x (9/765) minutes, i.e, 150 minutes.
Prabin would type 2,550 words in half an hour at the same speed. It would take him 150 minutes to type 12,750 words at the same speed.
Explanation:To find out how many words Prabin would type in half an hour, we need to determine how many minutes are in half an hour. Since there are 60 minutes in an hour, half an hour would be 30 minutes. Now, we can set up a proportion to find the number of words Prabin would type in half an hour:
765 words / 9 minutes = x words / 30 minutes
Cross-multiplying, we get:
9 * x = 765 * 30
Simplifying, we find:
x = (765 * 30) / 9
x = 2,550 words
To find out how long it would take Prabin to type 12,750 words at the same speed, we can set up another proportion using the given information:
765 words / 9 minutes = 12,750 words / t minutes
Cross-multiplying, we get:
9 * (12,750) = 765 * t

The sum of two numbers is 1476890. If the difference between the two numbers is 1500, what is the greater number ?
Let's call the two numbers x and y. We know from the problem statement that:
x + y = 1476890
y - x = 1500
To find the greater number, we can use the second equation to solve for one of the variables, and then substitute it into the first equation.
y = x + 1500
Now we can substitute this expression for y into the first equation:
x + (x + 1500) = 1476890
2x + 1500 = 1476890
2x = 1476890 - 1500
2x = 1475390
x = 1475390/2
x = 737695

a. Find the profit function, P(x), where x is the number of units of the product.
b. Find the break-even point.
c. How much was the profit/loss if 350 units were sold.
d. Sketch the graph of the cost function, C(x) and the revenue function, R(x). Indicate the break-even point and shade the profit and loss areas.
please help me to answer a,b,c and d.
a. The profit function P(x) is 10x - 5000.
b. The break even point is at 500 units.
c. If 350 units were sold, the loss was Rs. 1500.
d. The graph of the functions are attached below.
The solutions are obtained using the profit function.
What is profit function?
A profit function is a mathematical relationship that represents the difference produced when the cost function is subtracted from the revenue function. The graph of a profit function shows the optimal combination of revenues and expenses to produce the maximum profit.
a. We are given cost of raw material as Rs. 15 and the fixed cost is Rs. 5000. The product is sold for Rs.25 per unit.
This means that R(x) = 25x
We know that TC= FC + VC(x)
So, TC = 5000 + 15x
Therefore, the profit function will be
⇒Profit = R(x) - TC
⇒Profit = 25x - 5000 - 15x
⇒Profit = 10x - 5000
b. For break even, the profit should be 0.
Therefore,
⇒10x - 5000 = 0
⇒10x = 5000
⇒x = 500
So, the break even will be at 500 units.
c. We are given x=350
Putting this value in profit function, we get
⇒Profit = 10(350) - 5000
⇒Profit = 3500 - 5000
⇒Profit = -1500
So, there is loss of Rs. 1500.
d. The red line represents the cost function and the blue line represents the revenue function.
The break even point is the point where the two lines are meeting.
The area below the break even is the loss area and above it is the profit area.
Hence, the solutions are obtained.

What is a Parallelogram ?A basic quadrilateral with two sets of parallel sides is known as a parallelogram. In a parallelogram, the opposing or confronting sides are of equal length, and the opposing angles are of equal size.
A quadrilateral is a specific type of polygon known as a parallelogram if it contains two parallel opposed sides. A parallelogram has the following qualities:
The opposing sides are equal and parallel.Angles on either side are equal.The subsequent or neighboring angles are additional.All of the angles will be at right angles if any one of them is a right angle.The two diagonals are split in half.The parallelogram is divided into two congruent triangles by each diagonal.A parallelogram's total square sum and total square sum of its diagonals are equivalent. Also known as the parallelogram law.Each coordinate of the Parallelogram :
P (-3, 0) , A(3, -1) , R ( 2, -5) and T(-4, -4)
Length of PA = √((3 + 3)² + (-1 - 0)²) = √(36 + 1) = √37
Lenght of TR = √((-4 - 2)² + (-4 + 5)²) = √(36 + 1) = √37
Length of PT = √((-3 + 4)² + (0 + 4)²) = √(16 + 1) = √17
Length of AR = √((3-2)² + (-1 + 5)²) = √(16 + 1) = √17

The increase in the price of tacos shifts the demand curve to the left, causing a decrease in the equilibrium price and quantity of hamburgers.
The accompanying supply and demand diagram is depicting the market for hamburgers in your hometown. The event that is given is that the price of tacos increases. This will cause the demand curve to shift to the left, as consumers shift from hamburgers to tacos. As the demand curve shifts to the left, the equilibrium price will decrease and the equilibrium quantity will decrease. This is because the decrease in demand will cause the quantity demanded to fall and the decrease in demand will cause the price to fall. This shift in the supply and demand curves will cause the equilibrium point to move to the left and downward. The new equilibrium price will be lower than the original equilibrium price and the quantity will also be lower.

20 POINTS! WRITE A LINEAR EQUATION PERPENDICUALR TO -2Y = 5X + 8 PASSING THROUGH POINT (10,-1)
The equation of the line perpendicular to -2y = 5x + 8 and passes through (10, -1) is y = 2 / 5 x - 5.
How to represent linear equation?Linear equation can be represented in slope intercept form as follows:
y = mx + b
where
m = slope of the lineb = y-interceptTherefore, the equation is perpendicular to -2y = 5x + 8 and passes through (10, -1).
Perpendicular lines have slopes that are negative reciprocals of one another.
Therefore,
-2y = 5x + 8
y = - 5 / 2 x - 4
Therefore,
slope = 2 / 5
Let's find the y-intercept using (10, -1)
-1 = 2 / 5(10) + b
-1 = 20 / 5 + b
b = -1 - 4

(5x - 4)(x + 5)
O 5x²+21x-20
O4x²-17x+4
O 10x²+20x+10
O 10x²-10
Answer:
First choice: 5x²+21x-20
Step-by-step explanation:
This is easy to answer if you realize that there is only one way an x² term can appear in the result and that is by the multiplication of 5x and x which results in 5x².
The only choice which has 5x² as a term is the first: 5x²+21x-20
However, it is important to know the FOIL method to multiply two terms together
FOIL stands for First Outer Inner Last and is a technique for multiplying two terms of the form (a+b) and (c+d)
In (a + b) (c + d),
First terms are a and c so their product is ac
Outer terms are a and d so their product is ad
Inner terms are b and c with product bc
Last terms are b and d with product bd
The result is the sum of all these terms
Let's take (5x - 4)(x + 5)
F: 5x·x = 5x²
O: 5x · 5 = 25x
I: -4 ·x = -4x
L: -4·5 = -20
Adding up these individual terms we get
5x² +25x - 4x - 20 = 5x²+21x-20
So first choice is the correct answer
