The domain of the function y = 3/ x can be expressed as:
Domain: (−∞,0)∪(0,+∞)
The domain of the function y= 3/x represents all the possible values of x for which the function is defined. However, we need to be cautious because the function y = 3/ x has a restriction due to the presence of the denominator x.
In this case, the function y = 3/ x is defined for all real numbers except when x is equal to zero. This is because division by zero is undefined in mathematics.
Therefore, the domain of the function y = 3/ x can be expressed as:
Domain: (−∞,0)∪(0,+∞)
This means that the function y = 3/x is defined for all real numbers except x=0.

A limited-edition poster increases in value each year with an initial value of $18. After 1 year and an increase of 15% per year, the poster is worth $20.70. Write an equation that can be used to find the value, y, after x years? (Round money values to the nearest penny.)
Answer:
y=18(1.15)^x
Step-by-step explanation:
The general formula is
y=a(b)^x, where
a is the initial amount and
b is the growth (1+.15 in our case "an increase of 15%) or
decay rate (1 -.15 would be if the problem have said it decreased ).
x is the amount of time
y is the amount of money
20.70 = 18 (1.15)^1
The equation is:
y= 18(1.15)^x

find a value of c so that p(z ≥ c) = 0.55.
To find a value of c such that P(z ≥ c) = 0.55, we need to use a standard normal distribution table or calculator.From the standard normal distribution table, we find that the z-score corresponding to a right-tailed area of 0.55 is approximately 0.126.
Therefore, we have:
P(z ≥ c) = 0.55
P(z ≤ c) = 1 - P(z ≥ c) = 1 - 0.55 = 0.45
Using the standard normal distribution table, we find that the z-score corresponding to a left-tailed area of 0.45 is approximately -0.126.
So, c = -0.126.
Therefore, the value of c that satisfies P(z ≥ c) = 0.55 is approximately -0.126.

The largest taco contained approximately 1 kg of onion for every 6. 6 kg grilled teak. then Amount of grilled steak used: 6.6 (79.17) = 538.356 kg
What is a unit amount in math?
When a price is expressed as a quantity of 1, such as $25 per ticket or $0.89 per can, it is called a unit price. If you have a non-unit price, such as $5.50 for 5 pounds of potatoes, and want to find the unit price, divide the terms of the ratio
1 k + 6.6 k = 617.3
Where “k” is a constant value, a multiplier.
Solving for k:
7.8 k = 617.3
k = 617.3 /7.8
k= 79.17
So:
Amount of onion used:

Step-by-step explanation:
you must find the distance in the y- values and the x values, how each value increases or decreases. You may have heard of the phrase rise/run. To get to the pint (2,6) from (1,3), you must rise 3 units and move 1 unit. If you were to follow the rise/run method, you will need to divide the two numbers.

Answer:
We know that 9 = 30 + 9, so by the distributive property:
39(5) = (30 + 9)(5) = 30(5) + 9(5).
Multiply 30 × 5 and 9 × 5. Then add the products.
30(5) = 150, and 9(5) = 45, so
150 + 45 = 195 = 39(5).

Step-by-step explanation:
the given equation defines a paraboloid that lies below the plane z=0. Specifically, it is situated above the xy-plane, which means that the z-values of all points on the surface are greater than or equal to zero.
we can break down the equation z=18-2x^2-2y^2. This equation represents a paraboloid with its vertex at (0,0,18) and axis of symmetry along the z-axis. The first term 18 is the z-coordinate of the vertex and the last two terms -2x^2 and -2y^2 determine the shape of the paraboloid.
Since the coefficient of x^2 and y^2 terms are negative, the paraboloid is downward facing and opens along the negative z-axis. Therefore, all points on the paraboloid have z-values less than 18. Additionally, since the paraboloid is situated above the xy-plane, its z-values are greater than or equal to zero.
the paraboloid defined by the equation z=18-2x^2-2y^2 is situated below the plane z=0 and above the xy-plane. Its vertex is at (0,0,18) and it opens along the negative z-axis.

b. Explain why this table represents exponential growth.
c. Using this example, explain why any nonzero number raised to a power of zero is equal to one.
d. Write a rule for this table.

Hour 5 243 bacterium
Hour 6 729 bacterium
After 24 hours, the number of the bacterium will reach 282,429,536,481.
B) This table represents exponential growth because of the number of bacterium always being multiplied by 3.

Find the values of x and y that make these triangles congruent by the HL theorem
Answer:
A. x = 3, y = 2
Step-by-step explanation:
The hypotenuse and the length of one leg of one right triangle must be equal to the hypotenuse and corresponding length of the one leg of the other ∆ for both triangles to be equal by the HL Congruence Theorem.
Thus, let's find x and y by setting the corresponding lengths of the two right ∆s equal to each other.
Therefore:
x = y + 1 ----› eqn. 1
2x + 3 = 3y + 3 ----› eqn. 2
Substitute x = (y + 1) into eqn. 2, and solve for y.
2x + 3 = 3y + 3 ----› eqn. 2
2(y + 1) + 3 = 3y + 3
2y + 2 + 3 = 3y + 3
2y + 5 = 3y + 3
Collect like terms
2y - 3y = -5 + 3
-y = -2
Divide both sides by -1
y = 2
Substitute y = 2 into eqn. 1.
x = y + 1 ----› eqn. 1
x = 2 + 1

If a value of 71° is changed to 93°, which of the following measures changes the most and what is the new value?
Mean 82.3°
Median 86.5°
Range 48°
IQR 34°
Answer:
The new value of the list after changing 71° to 93° would be:
58, 61, 93, 77, 91, 100, 105, 102, 95, 82, 66, 57
The measure that changes the most would be the median. Without the change, the median was 86.5°, which was the average of the 7th and 8th values in the list (100 + 77) / 2. However, after changing 71° to 93°, the median becomes 91°, which is the average of the 6th and 7th values in the list (91 + 91) / 2.
Therefore, the median has changed by 4.5° (from 86.5° to 91°).

what is the potential difference between xi = 10 cm and xf = 30 cm in the uniform electric field ex = 2000 v/m ?
The potential difference between xi = 10 cm and xf = 30 cm in the uniform electric field ex = 2000 v/m can be calculated using the formula: ΔV = Ex * Δx. Therefore, the potential difference between the two points is 400 volts.
To find the potential difference between two points in a uniform electric field, we can use the formula:
Potential difference (V) = Electric field (E) × Distance (d)
In this case, the electric field (E) is given as 2000 V/m (ex = 2000 V/m). The distance (d) between the two points, xi = 10 cm and xf = 30 cm, is the difference between xf and xi, which is:
d = xf - xi = 30 cm - 10 cm = 20 cm
Now, convert the distance to meters:
d = 20 cm × (1 m / 100 cm) = 0.2 m
Now, we can find the potential difference (V):
V = E × d = 2000 V/m × 0.2 m = 400 V
So, the potential difference between xi = 10 cm and xf = 30 cm in the uniform electric field ex = 2000 V/m is 400 V.

Options:
x = (25.92 - 2.57) / 5
x = 25.92/5 + 2.57
x = (25.92 + 2.57) / 5
x = 25.92/5 - 2.57
Answer:
A
Step-by-step explanation:
the total is 25.92 and Elaina buys 2.57 eggs. So, you would have to first subtract 2.57 from 25.92 . Then she buys 5 bags of potatoes for x price.
This means that 23.35 (25.92-2.57) will have to be divided by 5 to get the price of 1 bag of potatoes.
