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

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

Answers

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.

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?

Answers

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

Given:

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.

Soh in Soh cah toa

                  So  sin(42)=x/10

                        10 times sin(42)=x

                             Evaluate using a calculator=6.69130606 and so on

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.

Answers

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.

∑ₙ₌₀°° (-3x)ⁿ / n!

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.

Explain in your own words when it is best to solve a system using analytical methods versus using graphical or algebraic methods.

Answers

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.
