Answer:
The smallest solution is x=-1
Step-by-step explanation:
Quadratic Equation
We have:
\(f(x)=2x+1\)
\(g(x)=-(x-1)^2+3\)
We'll find the solutions of f(x)=g(x), or:
\(2x+1=-(x-1)^2+3\)
Operating:
\(2x+1=-(x^2-2x+1)+3\)
\(2x+1=-x^2+2x-1+3\)
Rearranging all terms on the left side:
\(2x+1+x^2-2x+1-3=0\)
Simplifying:
\(x^2-1=0\)
Since the term with the x is missing, we can solve for x:
\(x^2=1\qquad\Rightarrow x=\sqrt{1}=\pm 1\)
There are two solutions:
x=1, x=-1
The smallest solution is x=-1

Compare . Who picked fruit at a faster pace ?
Answer:
Shawn.
Step-by-step explanation:
We can solve for apples per hour and pears per hour. For Shawn, to get the apples per hour, we do 4/2 which is 2 bushels of apples per hour. For pears, we do 5/2 which is 2.5 bushels of pears per hour.
When Carla is picking, we can do:4/3 which is 1 and 1/3, which is her apple bushel picking per hour. For her pears, she picks them at 2 bushels of pears per hour.
Since Shawn picks her apples quicker per hour, and her pears quicker per hour, Shawn picks at a faster fruit pace.

Major league baseball game durations are normally distributed with a mean of 180 minutes and a standard deviation of 45 minutes. What is the probability of a game duration of fewer than 210 minutes
The probability of a game duration of fewer than 210 minutes is 0.7486, or 74.86%.
To find the probability of a game duration of fewer than 210 minutes, we need to calculate the z-score and then use the standard normal distribution table.
First, we calculate the z-score using the formula: z = (x - mean) / standard deviation.
In this case, x = 210 minutes, mean = 180 minutes, and standard deviation = 45 minutes.
z = (210 - 180) / 45
z = 30 / 45
z = 0.67
Next, we look up the z-score of 0.67 in the standard normal distribution table. The table gives us the probability corresponding to the z-score.
From the table, we find that the probability corresponding to a z-score of 0.67 is 0.7486.
Therefore, the probability of a game duration of fewer than 210 minutes is 0.7486, or 74.86%..

Answer:
Deshaun = $590 - $35x
Isabel : $790 - $55x
$590 - $35x = $790 - $55x
Step-by-step explanation:
For Deshaun :
Amount in her account = $590
Amount she would have withdrawn by month x = $35 × x = $35x
The amount she would have in her account = $590 - $35x
For Isabel :
Amount in her account = $790
Amount she would have withdrawn by month x = $55 × x = $55x
The amount she would have in her account = $790 - $55x
Let x be the time when the money in their account would be equal =
$590 - $35x = $790 - $55x

As a result, in radians, x= n and x= -/2+2n (where n is an integer constant) are the answers to the given equation.
We must identify the values of x that fulfill the equation sinx(sinx+1)=0 in order to get the solution. We have two scenarios to take into account because the product of two components is zero if and only if at least one of the factors is zero. We need to think about two cases. The number x can be any integer multiple of if sinx=0. Sinx=-1, on the other hand, if sinx+1=0, then x=-/2+2n, where n is an integer. As a result, in radians, x= n and x= -/2+2n (where n is an integer constant) are the answers to the given equation.
The radians equivalents of x=n and x= -/2+2n, where n is an integer constant, are the solutions to the equation sinx(sinx+1)=0. By setting each element in the given equation to zero and locating x, we were able to arrive at these solutions. While the second factor sinx+1=0 produces x= -/2+2n, the first factor sinx=0 yields n.

To find the factored form, we need to factor the quadratic expression:
g(x) = (x - 7)(x + 3)
To find the x-intercepts, we set g(x) = 0 and solve for x:
(x - 7)(x + 3) = 0
x = 7 or x = -3
To find the y-intercept, we set x = 0 and evaluate g(x):
g(0) = (0 - 7)(0 + 3) = -21
Therefore, the y-intercept of g(x) is (0,-21).
For h(x) = x² + 8x + 12:

The probability that the motorist must stop at both signals is 0.2, at the first signal but not the second is 0.3, and at exactly one signal is 0.7.
The probability that the motorist must stop at both signals is calculated by multiplying the probability of stopping at the first signal (0.4) and the probability of stopping at the second signal (0.5). This gives a probability of 0.2 that the motorist must stop at both signals. The probability of stopping at the first signal but not the second one is calculated by subtracting the probability of stopping at the second signal (0.5) from the probability of stopping at the first signal (0.4). This gives a probability of 0.3 that the motorist must stop at the first signal but not the second one. The probability that the motorist must stop at exactly one signal is calculated by subtracting the probability of stopping at both signals (0.2) from the probability of stopping at at least one of the two signals (0.7).

You estimate you will be able to use the tractor for 10 years, and it will have a salvage value of 10% of the original by the end of its useful life.

Question 1 (b) options:
$40,000
$60,000
$100,000
unable to determine
Question 1a
To calculate the book value at the end of the first year using straight-line depreciation, we need to determine the annual depreciation expense first. The straight-line method assumes that the asset depreciates by an equal amount each year over its useful life. Therefore, we can use the following formula to calculate the annual depreciation:
Annual Depreciation = (Cost - Salvage Value) / Useful Life
Substituting the given values, we get:
Annual Depreciation = ($200,000 - $20,000) / 10 years = $18,000 per year
This means that the tractor will depreciate by $18,000 each year for the next 10 years.
To determine the book value at the end of the first year, we need to subtract the depreciation expense for the year from the original cost of the tractor. Since one year has passed, the depreciation expense for the first year will be:
Depreciation Expense for Year 1 = $18,000
Therefore, the book value of the tractor at the end of the first year will be:
Book Value = Cost - Depreciation Expense for Year 1
= $200,000 - $18,000
= $182,000
So the book value of the tractor at the end of the first year, December 31, 2022, using straight-line depreciation is $182,000. so the answer is D
Question 1(b)
To determine the farmer's noncurrent liabilities, we need to use the information provided to calculate the total liabilities and then subtract the current liabilities from it. Here's the step-by-step solution:
Calculate the total current liabilities using the current ratio:
Current Ratio = Current Assets / Current Liabilities
2 = $80,000 / Current Liabilities
Current Liabilities = $80,000 / 2
Current Liabilities = $40,000
Calculate the total liabilities using the debt/equity ratio:
Debt/Equity Ratio = Total Liabilities / Owner Equity
1.0 = Total Liabilities / $100,000
Total Liabilities = $100,000 * 1.0
Total Liabilities = $100,000
Subtract the current liabilities from the total liabilities to get the noncurrent liabilities:
Noncurrent Liabilities = Total Liabilities - Current Liabilities
Noncurrent Liabilities = $100,000 - $40,000
Noncurrent Liabilities = $60,000
Therefore, the farmer's noncurrent liabilities are $60,000. so the answer is B.

Step-by-step explanation:
Ornithologists have determined that some species of birds tend to avoid flights over large bodies of water during daylight hours. It is believed that more energy is required to fly over water than land because air generally rises over land and falls over water during the day. A bird with these tendencies is released from an island that is 5 km from the nearest point B on a straight shoreline, flies to a point C on the shoreline, and then flies along the shoreline to its nesting area D. Assume that the bird instinctively chooses a path that will minimize its energy expenditure. Points B and D are 13 km apart. (a) In general, if it takes 1. 4 times as much energy to fly over water as land, to what point C should the bird fly in order to minimize the total energy expended in returning to its nesting area?(b) Let W and L denote the energy (in joules) per kilometer flown over water and land, respectively. What would a large value of the ratio W/L mean in terms of the bird's flight? What would a small value mean? Determine the ratio W/L corresponding to the minimum expenditure of energy. (c) What should the value of W/L be in order for the bird to fly directly to its nesting area D? What should the value of W/L be for the bird to fly to B and then along the shore to D?(d) If the ornithologists observe that birds of a certain species reach the shore at a point 4 km from B, how many times more energy does it take a bird to fly over water than land?
The bird should fly to a point on the shoreline that is 4km from B to minimize total energy expenditure. A large W/L ratio means it's more efficient to fly over land, while a small ratio means it's more efficient to fly over water. The minimum ratio is 2.834. The W/L ratio should be 1 for the bird to fly directly to D, and 0 for the bird to fly to B and then along the shore to D. It takes a bird 1.4 times more energy to fly over water than land.
To minimize the total energy expended in returning to its nesting area, the bird should fly to the point on the shoreline that is 4 km from B. This can be found using the principle of least action, which states that the bird will choose the path that minimizes the integral of the energy expended along the path.
A large value of the ratio W/L would mean that it takes significantly more energy to fly over water than over land. A small value of the ratio would mean that there is not much difference in energy expenditure between flying over water and over land. The ratio W/L corresponding to the minimum expenditure of energy can be found using the same principle of least action as in part (a).
we are asked to determine the ratio W/L corresponding to the minimum expenditure of energy. Let x be the distance from B to C, and let y be the distance from C to D along the shoreline. Then the total energy expended in returning to its nesting area is given by
E(x, y) = L(13 - x - y) + W(√(25 - x²)) + W(√(y² + (13 - x)²))
To minimize E(x, y), we take partial derivatives with respect to x and y and set them equal to zero
dE/dx = L + Wx/√(25 - x²) - Wy/√(y² + (13 - x)²) = 0
dE/dy = L - Wy/√(y² + (13 - x)²) = 0
Solving for x and y, we get
x = 5√((W/L)/(1.4(W/L) - 1))
y = 13 - x - 5√((W/L)/(1.4(W/L) - 1))
The ratio W/L corresponding to the minimum expenditure of energy is obtained by substituting these values into the expression for E(x, y) and simplifying
W/L = 2.5(1.4 + √(1.96 + 4/25))/(4.9 - √(1.96 + 4/25))
W/L ≈ 2.834
Therefore, the ratio W/L corresponding to the minimum expenditure of energy is approximately 2.834.
To fly directly to its nesting area D, the value of W/L should be equal to 1. To fly to B and then along the shore to D, the value of W/L should be equal to 0.
If birds of a certain species reach the shore at a point 4 km from B, it takes 1.4 times more energy for the bird to fly over water than over land. This can be found by comparing the energy required to fly directly from the island to the point on the shoreline that is 4 km from B (which is entirely over water) to the energy required to fly along the shoreline from that point to D (which is entirely over land).

replacing x on the second formula we take that 5y-2+y=10
6y-2=10
6y=12
y=2
so x=5y-2=5*2-2=10-2=8
The table shows three functions and their output values for different values of x. Which equation represents h(x)? h(x) = (f(x))(g(x)) h(x) = f(x) – g(x) h(x) = f(x) + g(x)
The equation that represents h(x) is h(x) = (f(x))(g(x)).
To determine which equation represents h(x), we need to analyze the given table and understand the relationship between the functions f(x), g(x), and h(x).
Since h(x) represents the output values obtained by multiplying f(x) and g(x), we should look for values in the table where h(x) is the product of the corresponding values of f(x) and g(x).
Let's examine the table and compare the values:
x | f(x) | g(x) | h(x)
1 | 3 | 4 | 12
2 | 5 | 2 | 10
3 | 2 | 6 | 12
From the table, we can see that the values in the h(x) column are the products of the corresponding values in the f(x) and g(x) columns. Therefore, the equation that represents h(x) is h(x) = (f(x))(g(x)).

Answer true or false:
According to Boyle's Law, the volume of a gas varies directly with its pressure when the temperature is held constant.
True. Boyle's law states that the volume of a gas is inversely proportional to its pressure when the temperature is held constant.
This means that when the pressure of the gas increases, its volume decreases, and when the pressure decreases, the volume increases.For example, let's say that the pressure of a certain amount of gas is 1 atmosphere and the volume is 2 liters. If the pressure is increased to 2 atmospheres, then the volume will decrease to 1 liter in order to maintain the same temperature. Mathematically, this can be expressed as PV=k, where P is the pressure, V is the volume, and k is a constant.
In conclusion, Boyle's Law states that the volume of a gas varies directly with its pressure when the temperature is held constant, meaning that when the pressure increases, the volume decreases and when the pressure decreases, the volume increases.
