Answer:

{a}^{2}  +  {b}^{2}  =  {c}^{2}  \\  {8}^{2}  +  {6}^{2}  =  {c}^{2}  \\ 64 + 36 =  {c}^{2}  \\  {c}^{2}  = 100 \\ c = 10

So; C is hypotenuse = 10

___o__o__

sin x° = Opposite/hypotenuse

sin  \: x° =  \frac{6}{10}  \\  \\ sin  \: x° =  \frac{6 \div 2}{10 \div 2}  =  \frac{3}{5}

___o__o___

cos y°= Adjacent/ hypotenuse

cos \:  y° =  \frac{6}{10}  \\  \\ cos  \: y° =  \frac{6 \div 2}{10 \div 2}  =  \frac{3}{5}

__o__o__

\frac{sin  \: x°}{cos  \: y°}  =  \frac{ \frac{3}{5} }{ \frac{3}{5} }   =  \frac{3}{5}  \div  \frac{3}{5}  =  \frac{3}{5}  \times  \frac{5}{3}  = 1 \\  \\  \\  \frac{sin  \: x°}{cos \:  y°}  = 1

Given that a randomly chosen quadrilateral has four right angles, what is the probability that the quadrilateral also has four e
Alexxx [7]

Answer:

0.25

Step-by-step explanation:

This is the question on conditional probability

Let A - the quadrilateral has four right angles

B - the quadrilateral has four equal side lengths

Required probability = P(B/A)

By definition of continuous probability

P(B/A) = \frac{P(AB)}{P(A)}

P(AB) = \frac{2}{20} =0.10

P(A) = \frac{8}{20} =0.4

Hence given probability = \frac{0.1}{0.4} =0.25

The value of y in the triangle is 6°.

<h3>How to calculate the value of y in the triangle?</h3>

Firstly, it's important to note that a triangle has the total angles of 180°.

Based on the information, the triangle has interior angle measures of 11y, 10y + 10°, and 10y - 16º.

The value of y in the triangle will be illustrated thus:

11y + 10y + 10 + 10y - 16 = 180

31y - 6 = 180

31y = 180 + 6.

31y = 186

Divide.

y = 186 / 31

y = 6

The value of y is 6.

Find the equation of the quadratic function with vertex (– 2, – 6) that goes through the point (-4, -18)
torisob [31]

Answer:

y = -3(x+2)^2 - 6

Step-by-step explanation:

y = a(x+2)^2 -6

-18 = a(-2)^2 - 6

-12 = 4a

a = -3

y = -3(x+2)^2 - 6

National Income (NI) is the sum of the incomes that all individuals in an economy earn in the forms of wages,
Dennis_Churaev [7]

Answer:

\simeq 14.94  billion dollars

Step-by-step explanation:

During the period 1994 - 2004, the 'National Income' ,(NI) of Australia grew about 5.2% per year (measured in 2003 U. S, dollars).  In 1994 , the NI of Australia was $ 4 billion.

Now,

(2020 - 1994) = 26

Assuming this rate of growth continues, the NI of Australia in the year 2020 (in billion dollars) will be,

4 \times[\frac{(100 + 5.2)}{100}}]^{26}

=4 \times[\frac{105.2}{100}]^{26}

=\simeq 14.94  billion dollars (answer)
