Answer:

158,987 m²0.158986 km²

Step-by-step explanation:

42 gallons is about 0.158987 cubic meters. 1 micron is 1 micro-meter, or 10^-6 meters. The volume is the product of the area and thickness. For some area A, we have ...

  0.158987 m³ = (10^-6 m)A

  A = (10^6)(0.158987 m² = 158,987 m²

The area in square meters is 158,987.

__

A square km is (1000 m)² = 10^6 m². So, the area in square kilometers is about ...

  (158,987 m²)/(10^6 m²/km²) = 0.158987 km²

The area in square km is about 0.1590.

What is the area of the sector for the following circle? Round your answer to 4 decimal places. *

Answers

Answer:

Area = 13.0900 ft²

Step-by-step explanation:

Area of sector = θ/360 × πr²

We are assuming it's the area of the minor sector that we are asked to find.

Therefore,

θ = 360 - 300 = 60°

r = 5 ft

Plug in the values

Area of minor sector = 60/360 × π × 5²

Area = 13.0899694

Area = 13.0900 ft² (to 4 decimal places)

Step-by-step explanation:

The angle of the minor sector will be ,

> 360 - 300 = 60° .

Area of sector :-

> Area = ∅ / 360 × πr²

> A = 60/360 × 3.14 × 5ft²

> A = 13.09 ft²

Pls answer fast​

Answers

Answer: 2000/25 = 80 tiles

Step-by-step explanation:

Date: s=20

equation of surface area of a cube prism: surface area = 6s*2

the surface area to be covered with tiles is requires, the base is not included, so the equation reduces: surface area = 5s*2

subtitute values: surface area = 5(20)*2

= 5(400)

surface area = 2000

area of 2 tile is 5*2 = 25 square inches

2000/25 = 80 tiles

Step-by-step explanation:

[tex]x_1: 16.7\ 17.4\ 18.4\ 16.8\ 18.9\ 17.1\ 17.3\ 18.2\ 21.3\ 21.2\ 20.7\ 18.5[/tex]

Required

Use R code to determine the regression equation

[tex]y = b_o + b_1x_1 + b_2x_2[/tex]

First, write the following code in a R program

[tex]x1 <- c(16.7,17.4,18.4,16.8,18.9,17.1,17.3,18.2,21.3,21.2,20.7,18.5)[/tex]

[tex]y <- c(210,110,103,103,91,76,73,70,68,53,45,31)[/tex]

[tex]mod <- lm(y[/tex]~[tex]x1+x2)\\[/tex]

[tex]summary(mod)[/tex]

Next, run the program

See attachment for program and output

From the output, go to coefficients:

Check Estimate Std. column, you have the following:

[tex](Intercept) = 415.113[/tex]

[tex]x_1 = -6.593[/tex]

[tex]x_2 = -4.504[/tex]

[tex]y = b_o + b_1x_1 + b_2x_2[/tex] implies that:

[tex]b_o \to[/tex] Intercept

[tex]b_1 \to x_1[/tex]

[tex]b_2 \to x_2[/tex]

Hence, the least square regression equation is:

[tex]y = 415.113 -6.593 x_1 -4.504 x_2[/tex]

In problem formulation, the a. constraints are expressed in terms of the obtained objective function coefficients. b. objective is expressed in terms of the decision variables. c. nonnegativity constraints are always ignored. d. optimal solution is decided upon.

Answers

Answer: B. objective is expressed in terms of the decision variables

Step-by-step explanation:

Linear programming refers to an optimization technique that is used for a linear constraints system and the objective function.

The objective function simply means the quantity that an individual wants to optimize. It should be noted that the aim of linear programming is to get the values of the variables which will minimize or maximize the objective function. In problem formulation, objective is expressed in terms of the decision variables.

Therefore, the correct option is B

Answers

Answer:

no, it wont

Step-by-step explanation:

2g.h = v²

2(33)(40) = v²

v=√2640 = 51.38 ft/s

36 < 51.38

so, the rope will not get to the window

Classify the polynomial by the number of terms.
mx+b
•Trinomial
•Monomial
•Polynomial
•Binomial

Answers

Classification:

Monomial: One term

Mono = One

Polynomial: Multiple terms e.g. (2,3,4 and so on)

Poly: Many

Binomial: Two terms

Bi = Two

Trinomial: Three terms

Tri = Three  

The expression of "mx + b" would be classified as a monomial due to it having only one exponent.

You call an expression with a single term a monomial, an expression with two terms is a binomial, and an expression with three terms is a trinomial. An expression with more than three terms is named simply by its number of terms. For example a polynomial with five terms is called a five-term polynomial.
