What ia the value of cosθ given that (-2,9) is a point on the terminal side of θ ?
pentagon [3]

Hello from MrBillDoesMath!



Answer:

Choice B,    -2  sqrt(85) / 85



Discussion:

By definition,

cos(@) =  length of side adjacent to angle / hypotenuse

            =  -2/ ( sqrt (    (-2)^2 + (9^2)   )              (usin Pythag. theorem)

            = -2/ sqty (4 + 81)

            = -2 / (sqrt(85)

Multiply numerator and denominator by sqrt(85):

           =  (-2 / ( sqrt(85) ) * (sqrt(85)/sqrt(85) )

           = -2  sqrt(85) / 85


which is choice B


Thank you,

MrB

Dimensions of the other rectangle = ?

Let length and width of the other rectangle be x : y

According to the question:

\frac{6}{8} :\frac{x}{y}

\frac{6}{8} X \frac{y}{x}

So, the width of the rectangle would be 6 times the first rectangle and the length would be 8 times the first rectangle.

Hey there! :D

Subtract 20% by 10%, because it is asking how much less than the original price was by what percent. 

20%-10%= 10%

The ticket was 10% less than the original ticket.
