The domain of a function f(x) is x>_ 0, and the range is y<_ -1. What are the domain and range of its inverse function, f'(x)?
Answer:
Domain of inverse: [tex]x \le -1[/tex]
Range of inverse: [tex]y \ge 0[/tex]
Explanation:
The domain and range swap. This is because the inputs (x) and outputs (y) swap roles when going from the original function to the inverse, and vice versa.

Explain in your own words when it is best to solve a system using analytical methods versus using graphical or algebraic methods.
Answer:
Analytical methods are the preferred way to determine the outcome of a hypothesis when associated equations are simple and a precise answer is desired.
The algebraic method is more precise. When you "solve" a system you are really identifying the points that all of the lines have in common. In other words, the point at which the lines intersect. Finding the solution with graphs is not precise, but should usually be close enough if that is what is asked.
Find the smallest sample size n that will guarantee at least a 90% chance of the sample mean income being within $500 of the population mean income.
Answer:
The smallest sample size n that will guarantee at least a 90% chance of the sample mean income being within $500 of the population mean income is 48.
Step-by-step explanation:
The complete question is:
The mean salary of people living in a certain city is $37,500 with a standard deviation of $2,103. A sample of n people will be selected at random from those living in the city. Find the smallest sample size n that will guarantee at least a 90% chance of the sample mean income being within $500 of the population mean income. Round your answer up to the next largest whole number.
Solution:
The (1 - α)% confidence interval for population mean is:
[tex]CI=\bar x\pm z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}[/tex]
The margin of error for this interval is:
[tex]MOE=z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}[/tex]
The critical value of z for 90% confidence level is:
z = 1.645
Compute the required sample size as follows:
[tex]MOE=z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}[/tex]
[tex]n=[\frac{z_{\alpha/2}\cdot\sigma}{MOE}]^{2}\\\\=[\frac{1.645\times 2103}{500}]^{2}\\\\=47.8707620769\\\\\approx 48[/tex]
Thus, the smallest sample size n that will guarantee at least a 90% chance of the sample mean income being within $500 of the population mean income is 48.

in jacks class 18 of the students are tall and 10 are short. in Michaels class 54 students are tall and 30 students are short. which lass has a higher ratio of tall to short students
Answer:
uhh what kinda class is that big- anyways
Step-by-step explanation:
jacks class
18:10
If you divide 18 by 10 you get 1.8
Micheals class
54:30
If you divide 54 by 30 you get 1.8
therefore neither. They are both equivalent
the Ratio of tall to short students in the Michels and jacks class is equal which is 1.8.
What is ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
Given, in jacks class 18 of the students are tall and 10 are short. in Michaels's class, 54 students are tall and 30 students are short.
The ratio of tall to short students in jacks class = 18/10 = 1.8
The ratio of tall to short students in Micheals's class = 54/30
The ratio of tall to short students in Micheals's class = 1.8
Therefore, the Ratio of tall to short students in the Michels and jacks class is equal which is 1.8.

Answer:
∑ₙ₌₀°° (-3x)ⁿ / n!
R = ∞
Step-by-step explanation:
Maclaurin series is:
∑ₙ₌₀°° f⁽ⁿ⁾(0) xⁿ / n!
Find the nth derivative and evaluate at x=0:
f(x) = e⁻³ˣ
f⁽ⁿ⁾(x) = (-3)ⁿ e⁻³ˣ
f⁽ⁿ⁾(0) = (-3)ⁿ
The Maclaurin series is therefore:
∑ₙ₌₀°° (-3)ⁿ xⁿ / n!
∑ₙ₌₀°° (-3x)ⁿ / n!
Use ratio test to find the radius of convergence.
lim(n→∞)│aₙ₊₁ / aₙ│< 1
lim(n→∞)│[(-3x)ⁿ⁺¹ / (n+1)!] / [(-3x)ⁿ / n!]│< 1
lim(n→∞)│(-3x) n! / (n+1)!│< 1
lim(n→∞)│3x / (n+1)│< 1
0 < 1
The radius of convergence is infinite.

Easy Points!!!! What net force is required to accelerate a car at a rate of 2 m/s if the car has a mass of 3,000 kg?
Answer:
[tex]\boxed {\boxed {\sf 6,000 \ Newtons}}[/tex]
Step-by-step explanation:
Force can be found by multiplying the mass by the acceleration.
[tex]F= m*a[/tex]
The mass of the car is 3,000 kilograms and the acceleration is 2 meters per second squared.
[tex]m=3,000 \ kg \\a= 2 \ m/s^2[/tex]
Substitute the values into the formula.
[tex]F= 3,000 \ kg * 2 \ m/s^2[/tex]
Multiply.
[tex]F=6,000 \ kg*m/s^2[/tex]
1 kg*m/s² is equal to 1 Newton (N). Therefore, our answer of 6,000 kg*m/s² is equal to 6,000 Newtons.
[tex]F= 6,000 \ N[/tex]
The force required is 6,000 Newtons
Mass = 3,000 kg
Acceleration = 2 m/s^2
To Find:The net force.
Formula:Force = Mass × Acceleration
Explanation:Force = 3,000 kg × 2 m/s^2
Force = 6,000 kg × m/s^2
We know that kg × m/s^2 = Newton.
Hence, the net force required is 6,000 N.
6,000 N is the correct answer.
An envelope is 48 centimeters wide, and it measures 52 centimeters along the diagonal. How tall is the envelope?
Answer:
20 cm.
Step-by-step explanation:
Pythagorean Theorem a^2 + b^2 = c^2 (c is the hypotenuse).
Plug it in.
48^2 + b^2 = 52^2
2,304 + b^2 = 2,704
Isolate the variable.
b^2 = 400
b = 20
A grocery store sells a bag of 4 lemons for $0.79. Which pricing option would result in the same unit price for each lemon?
O A. twelve lemons for $2.37
O B. three lemons for $0.65
O C. six lemons for $1.20
OD two lemons for $0.35
Plz help for 20 points
Answer:
.79/4= .197. Or 20 cents each
The cost per unit of lemon in Option A is same as given per unit cost of lemon in grocery store that is $0.1975
What is cost per unit?Cost of per unit is cost of one unit. Cost per unit can be calculated simply by dividing the total cost of all items by the quantity of given item.
Given Cost of 4 lemons in a grocery store = $ 0.79
Cost of 1 lemon in the grocery store = total cost / 4 = $ 0.79÷ 4 = $0.1975
To check pricing option for same pricing check per unit price of each option.
A. Given twelve lemons for $2.37
Given Cost of 12 lemons = $ 2.37
Cost of 1 lemon = total cost / 12 = $ 2.37 ÷ 12 = $0.1975
B. Given three lemons for $0.65
Given Cost of 3 lemons = $ 0.65
Cost of 1 lemon = total cost / 3 = $ 0.65 ÷ 3 = $0.2167
C. Given six lemons for $1.20
Given Cost of 6 lemons = $1.20
Cost of 1 lemon = total cost / 6 = $ 1.20 ÷ 6 = $0.2
D. Given two lemons for $0.35
Given Cost of 2 lemons = $0.35
Cost of 1 lemon = total cost / 2 = $ 0.35 ÷ 2 = $0.175
Therefore , option A has same per unit cost $0.1975 as given pricing of the grocery store.
