The distance between (x1, y1) and (x2, y2) is found using the Pythagorean theorem. It is ...

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

For your values of (x1, y1) = (6, 5) and d = 5, substituting into the formula gives

\displaystyle 5=\sqrt{(x-6)^2+(y-5)^2}

This matches the first selection.

You are at a restaurant and your bill comes to $31.18. The sales tax is 6% and you give the waitress a 20 percent tip on the tot
Vanyuwa [196]

Answer:

$ 0.34   or 34 cents

Step-by-step explanation:

Bill amount = $31.18

sales tax = 6%  of $31.18

             =  0.06 ($31.18)

             = $1.8708

Bill with tax = $31.18+$1.8708

                  = $33.0508

value of tip = 20% of 33.0508

                   =  6.61016

Total  payment  = 33.0508+ 6.61016

                           = $39.66096

                          or $39.66

                         We get change of $40 - $39.66

                                                = $ 0.34        

We shall get back in  cents that will be 34   cents

 (6 pts) The average age of CEOs is 56 years. Assume the variable is normally distributed. If the SD is four years, find the pr
Alenkinab [10]

Answer:

The probability that the age of a randomly selected CEO will be between 50 and 55 years old is 0.334.

Step-by-step explanation:

We have a normal distribution with mean=56 years and s.d.=4 years.

We have to calculate the probability that a randomly selected CEO have an age between 50 and 55.

We have to calculate the z-value for 50 and 55.

For x=50:

z=\frac{x-\mu}{\sigma}=\frac{50-56}{4}=\frac{-6}{4}=   -1.5

For x=55:

z=\frac{x-\mu}{\sigma}=\frac{55-56}{4}=\frac{-1}{4}=-0.25

The probability of being between 50 and 55 years is equal to the difference between the probability of being under 55 years and the probability of being under 50 years:

P(50

Which of the following equations is non-linear?
lakkis [162]

2x + 6y = 14y - 19x^2 + 12 is a non-linear equation

Step-by-step explanation:

Lets define a linear equation first.

A linear equation is an equation in which there is no variable with exponent greater than 1 or the degree of the equation is 1.

So,

<u>x + 12 = -8x + 10 - 2y</u>

The equation is a linear equation because the degree of the equation is 1.

<u>x = 8x + 19 - 10y</u>

The equation is a linear equation because the degree of the equation is 1.

<u>2x + 6y = 14y - 19x^2 + 12</u>

The equation involve a term with exponent 2 which makes the degree of the equation 2 making it a quadratic equation

<u>2x + 13y + 14x - 7 = 16y - 3</u>

The equation is a linear equation because the degree of the equation is 1.

Hence,

2x + 6y = 14y - 19x^2 + 12 is a non-linear equation
