5 0

Answer:

n = 0

Step-by-step explanation:

1.2n + 1 = 1 - n

Add n and - 1 on both sides.

1.2n + n = 1 - 1

Combine like terms.

2.2n = 0

Divide both sides by 2.2.

n = 0

Find the perimeter of the quadrilateral that has vertices at (8,13), (5,-18), (-6,-6), and (-2,-5).

kodGreya [7K]

Answer:

72.14 units

Step-by-step explanation:

Let A(8,13), B(5,-18),C(-6,-6) and D(-2,-5)

Apply the distance formula as;

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Finding the lengths of the segments

For AB

$AB=\sqrt{(5-8)^2+(-18-13)^2} =\sqrt{(-3^2)+(-31^2)} =\sqrt{970} =31.14$

For BC

$BC=\sqrt{(-6-5)^2+(-6--18)^2} =\sqrt{(-11^2)+12^2} =\sqrt{265} =16.28$

For CD

$CD=\sqrt{(-2--6)^2+(-5--6)^2} =\sqrt{4^2+1^2} =\sqrt{16+1} =\sqrt{17} =4.12$

For DA

$DA=\sqrt{(8--2)^2+(13--5)^2} =\sqrt{10^2+18^2} =\sqrt{424} =20.6$

Finding the perimeter will be;

31.14+16.28+4.12+20.6=72.14 units

1/5x-2/3y=30<br> What is the value of the x in the equation when y=15

svetlana [45]

Answer:

$\frac{1}{5} x - \frac{2}{3} y = 30 \\ \frac{1}{5} x - \frac{2}{3} 15 = 30 \\ \frac{1}{5} x - \frac{30}{3} = 30 \\ \frac{1}{5} x - 10 = 30 \\ \frac{1}{5} x = 30 + 10 \\ \frac{1}{5} x = 40 \\ x = 40 \div \frac{1}{5} \\ x = 40 \times \frac{5}{1} \\ x = 40 \times 5 \\ x = 200$

The point (5,4) is rotated 180° clockwise

zmey [24]

Answer: $(-5,-4)$

Step-by-step explanation:

I assume that you need the new coordinates of the point after the rotation centered at the origin.

For this exercise it is important to remember the definition of "Rotation".

A Rotation is defined as a transformation which a figure is rotated about a fixed point known as "Center of rotation".

The figure before the transformation is called Pre-Image and the figure obtained after the transformation is called "Image".

The 180 degree rotation about the origin Rule states that:

$(x,y)$ → $(-x, -y)$

Therefore, knowing that the given point (5,4) is rotated 180 degrees clockwise about the origin, you can conclude that its Image is:

$(-5,-4)$

$100 is invested at 12% per year. If the amount is compounded annually, write the total amount after 2 years in exponential func

Sladkaya [172]

Answer:

A = $100(1.12)^2

Step-by-step explanation:

The standard formula for compound interest is given as;

A = P(1+r/n)^(nt) .....1

Where;

A = final amount/value

P = initial amount/value (principal)

r = rate yearly

n = number of times compounded yearly.

t = time of investment in years

For this case;

P = $100

t = 2years

n = 1

r = 12% = 0.12

Substituting the values, we have;

A = $100(1+0.12)^(2)

A = $100(1.12)^2
