Answer: The sequence has a common difference of 3, since each term is 3 more than the previous one. To find the 22nd term, we can use the formula for the nth term of an arithmetic sequence:
a_n = a_1 + (n-1)d
where a_1 is the first term, d is the common difference, and n is the term number we want to find.
In this case, we have:
a_1 = 1 (the first term)
d = 3 (the common difference)
n = 22 (the term number we want to find)
Substituting these values into the formula, we get:
a_22 = 1 + (22-1)3
= 1 + 21*3
= 64
Therefore, the 22nd term is 64.
Using the formula for the nth term, we can also check that the sequence up to the 22nd term is:
1, 4, 7, 10, 13, 16, 19, 22, 25, 28, 31, 34, 37, 40, 43, 46, 49, 52, 55, 58, 61, 64.

The solution to the inequality is:
x ∈ (-√2, 3/4) ∪ (√2, 4).
What is inequality ?
An inequality is a mathematical statement that compares two values or expressions using symbols such as <, >, ≤, or ≥. It indicates that one value or expression is less than or greater than the other. Inequalities can be solved by using various algebraic techniques to find the range of values that satisfy the inequality. Inequalities are commonly used in many areas of mathematics, such as in algebra, geometry, and calculus, as well as in real-world applications such as economics, physics, and engineering.
According to the question:
To solve the inequality f(4x-3)/(2-x²)>0, we first need to find the critical values of x where the function is equal to zero or undefined.
For f(4x-3) to be zero, we have 4x-3 = 0, which gives us x = 3/4.
For 2-x² to be zero, we have 2-x² = 0, which gives us x = ±√2.
We also need to check where the function is undefined, which is where the denominator (2-x²) is equal to zero. This occurs at x = ±√2.
So, we have critical values at x = -√2, 3/4, and √2.
We can use a sign chart to determine the intervals where the function is positive.
x -√2 3/4 √2
f(x)
(4x-3)/(2-x²) - + -
sign - + -
From the sign chart, we see that the function is positive on the intervals (-√2, 3/4) and (√2, 4). Therefore, the solution to the inequality is:
x ∈ (-√2, 3/4) ∪ (√2, 4).

While warming up at soccer practice, Ellie's teammate tosses the ball to Ellie. Ellie hits the ball upward with her head from a height of 1.6 meters at a velocity of 6 meters per second. The ball is in the air for some time until Ellie catches it at a height of 1 meter.
To the nearest tenth of a second, how long is the ball in the air before Ellie catches it?
The ball is in the air for approximately 0.8 seconds before Ellie catches it.
What is acceleration?The acceleration a body experiences as a result of gravity is known as the acceleration due to gravity. Its acceleration is around 9.81 metres per second squared close to the Earth's surface. In kinematics, many equations that describe how things move when affected by gravity include the acceleration caused by gravity as a constant.
Using kinematic equation to solve for the time (t):
Δy = vit + 0.5a*t²
Rearranging we have:
t = √((Δy - 0.5at²) / vi)
Substituting the values:
t = √((1 - 0.59.81t²) / 6)
t = 0.798 seconds
Hence, the ball is in the air for approximately 0.8 seconds before Ellie catches it.

The moneybox have 600 coins with 50 cent and 20 cent pieces .
How many cents were in the box
Answer:
Let's use algebra to solve the problem.
Let x be the number of 50 cent pieces in the moneybox.
Then the number of 20 cent pieces in the moneybox is 600 - x (since there are 600 coins in total).
The value of x 50 cent pieces is 50x cents.
The value of (600 - x) 20 cent pieces is 20(600 - x) = 12000 - 20x cents.
The total value of the coins is the sum of these two values:
50x + (12000 - 20x) = 3000 + 30x
So there are 3000 + 30x cents in the moneybox.
To find the total number of cents, we need to evaluate this expression for x:
3000 + 30x
We don't know the value of x, but we do know that there are 600 coins in the moneybox, so we can set up another equation:
x + (600 - x) = 600
Simplifying this equation, we get:
x + 600 - x = 600
Simplifying further, we get:
600 = 600
This equation is always true, which means we can solve for x in terms of 600:
x = 600 - (600 - x)
x = 600 - (600 - x)
x = 600 - (600 - x)
x = 600 - 600 + x
x = x
So x can be any value between 0 and 600.
To find the total number of cents in the moneybox, we need to evaluate the expression 3000 + 30x for any value of x between 0 and 600.
The minimum value of this expression occurs when x = 0:
3000 + 30(0) = 3000
The maximum value of this expression occurs when x = 600:
3000 + 30(600) = 21000
So there are between 3000 and 21000 cents in the moneybox, depending on how many 50 cent pieces there are.

There are 1300 Roman coins in the museum's collection in total.
How to determine the total number of Roman coins ?
To determine the total number of Roman coins in the museum's collection, we need to use the information given in the histogram. We know that there are 108 coins with a weight between 8 g and 17 g.
We can find the total frequency of all the coins by integrating the frequency density over the entire range of masses. To do this, we need to first find the width of each mass interval, which is given by the difference between the upper and lower mass values of each interval.
From the histogram, we can see that the width of each interval is 5 g.
So, the frequency of the coins between 8 g and 17 g can be calculated as:
Frequency = frequency density × interval width
Frequency = 10 × 5 = 50
This means that there are 50 coins in the museum's collection with a mass between 8 g and 17 g.
To find the total number of coins in the collection, we need to sum up the frequency of all the intervals.
To do this, we can calculate the area of each rectangle formed by the interval width and frequency density, and then sum up all these areas.
The total number of coins in the collection is given by:
Total number of coins = sum of frequencies over all intervals
Total number of coins = 50 + (15 × 15) + (20 × 20) + (25 × 25)
Total number of coins = 50 + 225 + 400 + 625
Total number of coins = 1300

To factor 0.15c - 0.072, the first step is to find the greatest common factor (GCF) of the terms. In this case, the GCF is 0.072. This means that 0.072 can be divided out of both terms.
The next step is to divide out 0.072 from both terms. This gives 0.15c/0.072 = 0.208 and -0.072/0.072 = -1.
After this, we can combine the terms by multiplying the coefficients: 0.208 x -1 = -0.208.

The statement "Construct a line from A perpendicular to the y-axis, determine the distance from A to the y-axis along this perpendicular line, find a new point on the other side of the y-axis that is equidistant from the y-axis" accurately describes how to reflect point A (3, -1) over the y-axis
How to reflect a point over the y-axis?To reflect a point over the y-axis, you need to find a new point that is the same distance from the y-axis as the original point, but on the other side of the y-axis.
This can be done by constructing a perpendicular line from the original point to the y-axis, determining the distance from the original point to the y-axis along this line, and then finding a new point on the other side of the y-axis that is the same distance from the y-axis as the original point.
