Answer:

(0,s)

Step-by-step explanation:

To find points on a graph, you start going horizontal, then vertical, (x,y). so if x, or in this case r, is zero, B would be (0,s)

From right triangle trigonometry, we have the following:

\displaystyle{ tan(35^o)= \frac{opposite \ side }{adjacent \ side }, 


where the "opposite side" means the opposite side to angle with measure 35^o, and "adjacent side" means the adjacent side to angle with measure 35^o.

tan(35^o) is a constant which can be found using a calculator.

In the calculator of the pc press: view - scientific - 35 - tan.

 This gives tan(35^o)=0.7


Thus, back in the equation \displaystyle{ tan(35^o)= \frac{opposite \ side }{adjacent \ side } we substitute as follows and solve:


\displaystyle{0.7= \frac{x }{12 }\\\\

x=0.7\cdot12=8.4

Which pair of equations represents two perpendicular lines? <br>answers shown in picture. ​
kolezko [41]

Answer:

y =1/2x+6

y = -2x+2

Step-by-step explanation:

Perpendicular line have slopes that multiply to -1

The slopes are negative reciprocals

-4*4 = 16  not perpendicular

1/2 * -2 = -1  perpendicular

1/5 *5 = 1  not perpendicular

2/3 * 2/3 = 4/9  not perpendicular

The square of a whole number 'n' lies between 80 and 150. Find all possible values for 'n'.
pychu [463]
The square of a whole number n lies between 80 and 150, so n lies between √80 and √150.

\sqrt{80} \approx 8.9 \\&#10;\sqrt{150} \approx 12.2

n is a whole number and lies between 8.9 and 12.2, so n can be 9, 10, 11, or 12.

The possible values for n are 9, 10, 11, and 12.
