Step-by-step explanation:
Given
3x - x² ← factor out - 1 from each term
= - (x² - 3x)
Using the method of completing the square
add/subtract ( half the coefficient of the x- term)² to x² - 3x
= - (x² + 2(- \(\frac{3}{2}\))x + \(\frac{9}{4}\) - \(\frac{9}{4}\) )
= - (x - \(\frac{3}{2}\) )² - 1(- \(\frac{9}{4}\) )
= \(\frac{9}{4}\) - (x - \(\frac{3}{2}\) )²
The length of YZ is. inches
Answers
Step-by-step explanation:
So the center of the circle is x. This means any straight line through that point is the diameter of the circle. So the radius is half of the diameter. So if the radius of the circle is 7 inches and line YZ is the diameter, then to find the answer just multiply the radius by 2.
So
7 x 2 = 14
The length of the line YZ is then 14 inches, because the line is the diameter of the circle.

Using linear function you would need to cross the bridge 30 times for the costs of the two toll options to be the same.
What is meant by linear function ?To find out how many times you would need to cross the bridge for the costs of the two toll options to be the same, we need to set up an equation.Let x be the number of times you need to cross the bridge.For the transponder option: 22.50 + 4x = costFor the toll-by-plate option: 5.25x + 1.25x = costSince the costs of the two options need to be equal, we can set the two equations equal to each other and solve for x:22.50 + 4x = 5.25x + 1.25x + 22.504x = 5.25x + 1.25x0.75x = 22.50x = 30So you would need to cross the bridge 30 times for the costs of the two toll options to be the same.To learn more about linear function refer:

A chicken farm produces 10,000 eggs each day. It is determined that 0.3% of the eggs produced are cracked upon packaging with a margin of error of 0.05%.
How many eggs will be cracked upon packaging in one week?
Enter your answer by filling in the boxes to correctly complete the statement.
There are between __ and __ eggs that will be cracked upon packaging in one week.
Answers
There are between 175 and 245 eggs that will be cracked upon packaging in one week.
To find the number of eggs that will be cracked upon packaging in one week, we first need to calculate the daily rate of cracked eggs:
Daily rate of cracked eggs = 0.3% of 10,000 = 0.3/100 x 10,000 = 30
Next, we can find the weekly rate of cracked eggs by multiplying the daily rate by the number of days in a week:
Weekly rate of cracked eggs = 30 x 7 = 210
To determine the margin of error, we can use the formula:
\(Margin \ of\ error = z \sqrt(p \times (1 - p) / n)\)
where z is the z-score for the desired confidence level, p is the proportion of cracked eggs, and n is the sample size.
In this case, the number of eggs produced in one week, which is 10,000 x 7 = 70,000.
Assuming a 95% confidence level, the z-score is approximately 1.96. Substituting the given values, we get:
Margin of error = 1.96 x √(0.003 x 0.997 / 70,000) ≈ 0.00040514945
Therefore, the range of possible values for the number of cracked eggs in one week is:
210 ± 0.05% of 70,000 = 210 ± 35.

The exercise wants us to prove that f(g(x)) = x and g(f(x)) = x, then let's prove it.
First, let's start with f(g(x)) = x. Let's do f(g(x)), we must find that it's equal to x.
\(\begin{gathered} f(x)=x^2-3 \\ g(x)=\sqrt{x+3} \\ \\ f(g(x))=(\sqrt{x+3})^2-3 \end{gathered}\)Now we simplify that expression, then
\(\begin{gathered} f(g(x))=(\sqrt{x+3})^2-3 \\ \\ f(g(x))=x+3-3 \\ \\ f(g(x))=x \end{gathered}\)Then we can confirm that f(g(x)) = x. Now let's do the same for g(f(x)), then
\(\begin{gathered} g(x)=\sqrt{x+3} \\ f(x)=x^2-3 \\ \\ g(f(x))=\sqrt{(x^2-3)+3} \\ \\ g(f(x))=\sqrt{x^2-3+3} \\ \\ g(f(x))=\sqrt{x^2} \\ \\ g(f(x))=x \end{gathered}\)As we expected, it's also true, hence

find the third, fourth, and fifth terms of the sequence defined by
a1 = 1, a2 = 3,
and
an = (−1)nan − 1 + an − 2
for
n ≥ 3.
Answers
The third term (a3) of the sequence is -8, the fourth term (a4) is 35, and the fifth term (a5) is -183. These values are obtained by applying the given formula recursively and substituting the previous terms accordingly. The calculations follow a specific pattern and are derived using the provided formula.
The sequence is defined by the following formula:
a1 = 1, a2 = 3,
and
an = (-1)nan - 1 + an - 2 for n ≥ 3.
To find the third term (a3), we substitute n = 3 into the formula:
a3 = (-1)(3)(a3 - 1) + a3 - 2.
Next, we simplify the equation:
a3 = -3(a2) + a1.
Since we know a1 = 1 and a2 = 3, we substitute these values into the equation:
a3 = -3(3) + 1.
Simplifying further:
a3 = -9 + 1.
Therefore, the third term (a3) is equal to -8.
To find the fourth term (a4), we substitute n = 4 into the formula:
a4 = (-1)(4)(a4 - 1) + a4 - 2.
Simplifying the equation:
a4 = -4(a3) + a2.
Since we know a2 = 3 and a3 = -8, we substitute these values into the equation:
a4 = -4(-8) + 3.
Simplifying further:
a4 = 32 + 3.
Therefore, the fourth term (a4) is equal to 35.
To find the fifth term (a5), we substitute n = 5 into the formula:
a5 = (-1)(5)(a5 - 1) + a5 - 2.
Simplifying the equation:
a5 = -5(a4) + a3.
Since we know a4 = 35 and a3 = -8, we substitute these values into the equation:
a5 = -5(35) + (-8).
Simplifying further:
a5 = -175 - 8.
Therefore, the fifth term (a5) is equal to -183.
In summary, the third term (a3) is -8, the fourth term (a4) is 35, and the fifth term (a5) is -183.

Answers
Micah increased his practice time by 40 minutes.
The percent increase of Micah's practice time is equal to 80%.
How to calculate the percentage increase?In Mathematics, percentage increase can be calculated by using the following mathematical equation (formula):
Percentage increase = [Final value - Initial value]/Initial value × 100
Substituting the given parameters into the percentage increase formula, we have the following;
Percentage increase of practice time = [90 - 50]/50 × 100
Percentage increase of practice time = 40/50 × 100
Percentage increase of practice time = 0.8 × 100

During 1 hour, Seith can do 1/x of the work, Ted can do 1/(x+1) of the work, then we have
1/x + 1/(x + 1) = 1/6
(2x + 1)/[x(x+1)] = 1/6
x(x+1)=6(2x+1)
x^2 + x = 12x + 6
x^2 - 11x - 6 = 0
