Answer:

16.93 units

Step-by-step explanation:

Length of a segment having extreme ends [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,

d = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

ML = [tex]\sqrt{(4-1)^2+(0-4)^2}[/tex]

     = 5 units

LP = [tex]\sqrt{(1+1)^2+(4+2)^2}[/tex]

    = [tex]\sqrt{40}[/tex] ≈ 6.32 units

PN = [tex]\sqrt{(-1-2)^2+(-2-0)^2}[/tex]

     = [tex]\sqrt{13}[/tex]

     ≈ 3.61 units

NM = [tex]\sqrt{(4-2)^2+(0)^2}[/tex]

      = 2 units

Perimeter of the polygon MLPN = ML + LP + PN + NM

                                                     = 5 + 6.32 + 3.61 + 2

                                                     = 16.93 units

Step-by-step explanation:

factor out common terms 2(3x+y)=12divide both sides by 2

3x+y=[tex]\frac{12}{2}[/tex] simplify 3x+y=6 subtract 3 from both sides

y=6-3x

Answer:

- 2 - 5i

Step-by-step explanation:

Given

= - 2 - 5i

Answer:

A. 56 52 feet

Step-by-step explanation:

[tex]d = 18 \: ft \\ c = \pi \: d \\ c = 3.14 \times 18 \\ c = 56.52 \: ft[/tex]

The closest to the circumference is  56 52 feet.

It is required to find the circumference.

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.

Given:

Diameter of a circle is 18 feet.

Radius=18/2=9  feet.

We know that

circumference of the circle= 2πr

According to given question we have,

circumference of the circle= 2πr

circumference of the circle=2 π*9

circumference of the circle=56.54 feet.

Therefore, the closest to the circumference is  56 52 feet.

[tex]\huge\boxed{slope=-\dfrac{3}{2}}[/tex]

Step-by-step explanation:

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have the points (2, 3) and (-4, 12).

Substitute:

[tex]m=\dfrac{12-3}{-4-2}=\dfrac{9}{-6}=-\dfrac{9:3}{6:3}=-\dfrac{3}{2}[/tex]

Answer:

[tex]y = \frac{c-ax}{b}[/tex]

Step-by-step explanation:

ax + by = c

subtract ax from both sides

ax + by = c

-ax             -ax

=

by = c- ax

divide b on both sides

[tex]\frac{by}{b}[/tex] = [tex]\frac{c- ax}{b}[/tex]

=

[tex]y = \frac{c-ax}{b}[/tex]

Answer:

  2.9403×10^15

Step-by-step explanation:

Your calculator can work this out for you.

  [tex](8.91\times10^2)(3.3\times10^{12})=(0.891\times10^3)(3.3\times10^{12})\\\\=(0.891\times3.3)(10^{3+12})=\boxed{2.9403\times10^{15}}[/tex]

The applicable rule of exponents is ...

  (10^a)(10^b) = 10^(a+b)

Additional comments

You can keep a product the same if you divide one factor by 10 and multiply the other factor by 10:

  8.91×10² = (8.91/10)(10×10²) = 0.891×10³

I like to "pre-scale" the numbers in a problem like this so that the product comes out in scientific notation with no adjustment needed. That is, the product of the two mantissas is a number between 1 and 10.

Here, you can tell the product of 8.91 and 3.3 will be more than 24, so scaling will be necessary. It is convenient to scale the larger mantissa to be less than 1 so the product comes out less than 10. That is why we made it 0.891×10³.

Answer:

(0, 5 )

Step-by-step explanation:

The y- intercept is where the function crosses the y- axis.

This occurs when x = 0 , thus

From the table when x = 0 , f(x) = 5 , thus

y- intercept is (0, 5 )

y- intercept is (0, 5 )

Answer:

t = 74 / 9

Step-by-step explanation:

-9(t - 2) = 4(1 - 15)

-9t + 18 = 4 - 60

-9t + 18 = -56

 -18      -18

-9t = -74

/-9     /-9

t = 74 / 9

t = 8.22

Answer:

t = 74 / 9 ~= 8.222

Step-by-step explanation:

-9 ( t - 2 ) = 4 ( 1 - 15 )

-9 * t + -9 * -2 = 4 * 1 + 4 * -15

-9t + 18 = 4 + -60

-9t + 18 = -56

-9t = -56 + -18

-9t = -74

t = 74 / 9

Alternatively:

-9 ( t - 2 ) = 4 ( 1 - 15 )

-9 * t + -9 * -2 = 4 ( - 14 )

-9t + 18 = -56

-9t = -56 + -18

-9t = -74

t = 74 /9

Answer:

(- [tex]\frac{1}{2}[/tex], [tex]\frac{1}{2}[/tex] )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] ]

Here (x₁, y₁ ) = (6, 7) and (x₂, y₂ ) = (- 7, - 6) , thus

midpoint = ([tex]\frac{6-7}{2}[/tex] , [tex]\frac{7-6}{2}[/tex] ) = ( - [tex]\frac{1}{2}[/tex] , [tex]\frac{1}{2}[/tex] )

Answer:

s = students, m = money they pay

S(M)=350

The expression that represents the amount that each student needs to fundraise is -  y = [tex]$\frac{350}{x}[/tex]

We have robotics team who needs to purchase $350 of new equipment.

We have to determine the expression which represents the amount that each student needs to fundraise.

Assume the amount paid by each student be x. Then -

50x = 3000

x = $60

According to the question, we have -

Assume that the number of students in the robotics team are x.

Assume that the money contributed by each member is $y.

Then, the expression represents the amount that each student needs to fundraise is -

xy = 350

y = [tex]$\frac{350}{x}[/tex]

Answer:

its A  i got you

Step-by-step explanation:

The correct classification of [tex]\sqrt{32}[/tex] is it is an irrational number.

A perfect square number when taken the square root of it results in an integer.

Numbers that are not perfect squares when taken the square root of it are irrational numbers.

One method of obtaining square roots for perfect squares is prime factorization.

We know if a number is not a perfect square it is an irrational number.

[tex]\sqrt{32}[/tex] can be written as [tex]\sqrt{2\times2\times2\times2\times2[/tex] which is [tex]2^2\sqrt{2}[/tex].

= [tex]4\sqrt{2}[/tex] and [tex]\sqrt{2}[/tex] is not a perfect square so it is an irrational number.
