Answer:
Day 44
Step-by-step explanation:
Given function:
\(f(t)=500t^2\)
where:
f = number of daily hitst = times (in days)To find the day on which the number of daily hits reaches 1,000,000, set the function to 1,000,000 and solve for t:
\(\begin{aligned}f(t) & =1000000\\ \implies 500t^2 & = 1000000\\ t^2&=\dfrac{1000000}{500}\\ t^2 & = 2000\\ t & = \pm \sqrt{2000}\\ t & = \pm 44.72135955...\end{aligned}\)
As time in positive, t = 44.72135955 only.
This tells us that the number of daily hits reaches 1,000,000 during the 44th day.

your group fundraiser has a goal of $75 to pay for a new piece of equipment. you are selling pencils () for $0.50 and bracelets () for $1.00.
Answers
To reach your fundraising goal of $75, you will need to sell 150 pencils for $0.50 each and 0 bracelets for $1.00 each.
To reach your fundraising goal of $75, you can sell pencils for $0.50 and bracelets for $1.00.
1. Calculate the total amount of money needed to reach the goal:
Goal amount = $75
2. Determine the number of pencils and bracelets you need to sell to reach the goal:
Let's assume you sell x number of pencils and y number of bracelets.
The amount raised from selling pencils = x * $0.50
The amount raised from selling bracelets = y * $1.00
The total amount raised from both items should be equal to the goal amount:
x * $0.50 + y * $1.00 = $75
3. Simplify the equation:
0.50x + 1.00y = 75
4. Solve for one variable in terms of the other:
Let's solve for x in terms of y:
0.50x = 75 - 1.00y
x = (75 - 1.00y) / 0.50
5. Substitute the value of x into the equation:
(75 - 1.00y) / 0.50 * 0.50 + y * $1.00 = $75
75 - 2y + y = 75
-y = 0
y = 0
6. Find the value of x:
x = (75 - 1.00 * 0) / 0.50
x = 75 / 0.50
x = 150
To reach your fundraising goal of $75, you will need to sell 150 pencils for $0.50 each and 0 bracelets for $1.00 each.

For a taxable income of $1,80,900, the effective tax rate is 21.11%.
what is meant by marginal tax?Marginal tax is the tax rate applied to an individual’s last dollar of income. It is the additional tax that must be paid on any additional income earned. In other words, it is the tax rate that applies to an individual’s income after all deductions. For example, if an individual’s income is $50,000 and the marginal tax rate is 25%, then the individual must pay an additional $12,500 in taxes on top of the $25,000 in taxes already paid on their $50,000 income.
Marginal tax rates are progressive, meaning that as an individual’s income increases, the marginal tax rate will increase as well. The marginal tax rate is important to understand because it helps individuals determine how much additional income they will need to earn in order to make up for the taxes they will have to pay on that income. It is also important to understand how marginal tax rates can affect tax planning strategies.
To determine the effective tax rate for a taxable income of $180,900, calculate the sum of the marginal tax rates for each tax bracket that the $180,900 falls into. The taxable income of $180,900 is greater than $89,075 and less than $170,050. The marginal tax rates for these two tax brackets are 22% and 24%, respectively. The sum of the marginal tax rates is 46%. Divide the sum by the taxable income of $180,900 to get the effective tax rate of 21.11%. Round the final answer to the nearest hundredth to get 21.11%.

Answers
The value of x is 2yw + y - 1 for the given equation 2x + 2/y = 4w + 2.
According to the given question.
We have an equation
2x + 2/y = 4w + 2
Since, we have to find the value of x for the given equation
2x + 2/y = 4w + 2
Thereofore,
2x + 2/y = 4w + 2
⇒ 2(x + 1)/y = 2(2w + 1) (taking 2 common from both the sides)
⇒ (x + 1)/y = 2w + 1
⇒ (x + 1) = y(2w + 1) (multiplying both the sides by y)
⇒ x + 1 = 2yw + y
⇒ x = 2yw + y - 1 ( subtracting 1 both the sides)
Hence, the value of x is 2yw + y - 1 for the given equation 2x + 2/y = 4w + 2.

Answers
Answer:
248
Step-by-step explanation:
Solution for What is 400 percent of 62:
400 percent *62 =
(400:100)*62 =
(400*62):100 =
24800:100 = 248
Now we have: 400 percent of 62 = 248
Question: What is 400 percent of 62?
Percentage solution with steps:
Step 1: Our output value is 62.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$62=100\%.
Step 4: Similarly, x=400\%.
Step 5: This results in a pair of simple equations:
62=100\%(1).
x=400\%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
\frac{62}{x}=\frac{100\%}{400\%}
Step 7: Again, the reciprocal of both sides gives
\frac{x}{62}=\frac{400}{100}
\Rightarrow x=248
Therefore, 400 of 62 is 248
Answer:
248
Step-by-step explanation:
\(\frac{y}{400}: \frac{62}{100}\)
y · 100 = 62 · 400
100y = 24800
100y ÷ 100 = 24800 ÷ 100

What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
M varies inversely with the square of O.
And, When O is 6, M is 0.5.
Now,
Since, M varies inversely with the square of O.
Hence, We get;
⇒ M α 1/O²
⇒ M = k/O²
Where, k is constant of inverse proportional.
When, O is 6, M is 0.5.
So, We get;
⇒ 0.5 = k/6²
⇒ 0.5 × 36 = k
⇒ k = 18
So, We get;
⇒ M = 18/O²
Put O = 2,
⇒ M = 18/2²
⇒ M = 18/4
⇒ M = 4.5
Thus, The value of M for O = 2 will be;
⇒ M = 4.5

Ball resting on the top of a hill at a height of 20 m. Position A is the top of the hill. Position B is at the bottom of the hill on ground level. According to the law of conservation of energy, which statement best describes the total energy of the system at point B if the system is isolated? The total energy will be less than the initial potential energy because some is lost to the surroundings. The total energy will be more than the initial potential energy because it includes the surroundings. The total energy will be equal to the initial potential energy because no energy is lost to the surroundings. The total energy will be equal to the initial potential energy because it is equal to the total energy of the surroundings.
Answers
The statement that best describes the total energy of the system at point B if the system is isolated is that the total energy will be less than the initial potential energy because some is lost to the surroundings.
According to the law of conservation of energy, energy cannot be created or destroyed but can only be transferred or converted from one form to another within a closed or isolated system. In the system described in Figure 3, the ball is released from rest at position A, where it has gravitational potential energy due to its height above the ground. As the ball moves down the track towards position B, it loses potential energy but gains kinetic energy, until it reaches the ground at position B where it has no potential energy but maximum kinetic energy. If the system is isolated, meaning that there are no external forces acting on the ball except for air resistance and friction, the total energy of the system must remain constant throughout its motion, and the sum of the kinetic and potential energy at any point must equal the initial potential energy at position A. Therefore, the statement that best describes the total energy of the system at point B if the system is isolated is that the total energy will be less than the initial potential energy because some is lost to the surroundings. This is because the air resistance and friction acting on the ball during its motion convert some of its mechanical energy into other forms of energy such as heat and sound, which are lost to the surroundings. However, the total energy of the system must still be conserved, and the sum of the kinetic and potential energy at point B must be equal to the initial potential energy at position A, minus the energy lost to the surroundings due to air resistance and friction.

which of the following is a discrete data random variable? cars finished in a factory each day a person's height each birthday a person's weight on each year the volume of water in a swimming pool each day
Answers
A discrete data random variable is a random variable that can only take on a finite or countable number of values.
Out of the options given, the number of cars finished in a factory each day is a discrete data random variable. This is because the number of cars finished can only take on a finite number of values, such as 0, 1, 2, 3, and so on. It cannot take on any value between these integers, and there are only a finite number of possible values.
In contrast, a person's height and weight are continuous data random variables, as they can take on any value within a certain range (for example, a person's height can take on any value between 4 feet and 7 feet).
Similarly, the volume of water in a swimming pool can take on any value within a certain range, and is also a continuous data random variable.
Therefore, the only discrete data random variable out of the options given is the number of cars finished in a factory each day.

Jack and Jill exercise in a 25.0 m long swimming pool. Jack swims 9 lengths of the pool in 150.3 s(2 min and 30.3 s), whereas Jill, the faster swimmer, covers 10 lengths in the same time interval. Find the average velocity and average speed of each swimmer. Jack's average velocity: Jack's average speed: Jill's average velocity: Jill's average speed: m/s
Answers
First, let's understand the difference between speed and velocity. Speed is a scalar quantity that refers to "how fast an object is moving." It does not contain any information about the direction of the object's movement. On the other hand, velocity is a vector quantity that refers to "the rate at which an object changes its position." It is speed in a given direction.
Now, we can find the total distance each swimmer travels and the average velocity and speed for each.
The total distance Jack swims is 9 lengths * 25.0 m/length = 225.0 m.
His average speed, which is the total distance divided by the time, is 225.0 m / 150.3 s = 1.497 m/s (rounded to three decimal places).
For the average velocity, we need to remember that when Jack finishes swimming, he is back where he started after an odd number of lengths. This means his displacement is one length of the pool or 25.0 m. So his average velocity is 25.0 m / 150.3 s = 0.166 m/s (rounded to three decimal places).
Now for Jill:
The total distance Jill swims is 10 lengths * 25.0 m/length = 250.0 m.
Her average speed is 250.0 m / 150.3 s = 1.663 m/s (rounded to three decimal places).
However, Jill finishes at the opposite end of the pool because she swam an even number of lengths, so her displacement is two lengths or 50.0 m. Therefore, her average velocity is 50.0 m / 150.3 s = 0.333 m/s (rounded to three decimal places).
So:
- Jack's average velocity: 0.166 m/s
- Jack's average speed: 1.497 m/s
- Jill's average velocity: 0.333 m/s
- Jill's average speed: 1.663 m/s
