Find the equation of the line. <br> Please need help badly!!

hoa [83]

Answer:

lets consider two end points are the marked points ,

Then ,

(1,5)=x1,y1

(-1,-3)=x2,y2

line passes through point(1,0)=x3,y3

slope of line ,m = (y2-y1)/(x2-x1)

= (-3-5)/(-1-1)

Eqn of line is:

y-y3=m(x-x3)

y-0 = 4(x-1)

y=4x-4

4x-y=4 is reqyuired eqn..

If cos A = 3 over 11, then which of the following is correct?

ziro4ka [17]

Answer: The answer is (a) sec A = 11 over 3.

Step-by-step explanation: Given that Cosine of an angle 'A' is 3 over 11,

i.e.,

$\cos A=\dfrac{3}{11}.$

And we need to find which one of the given four options is correct.

We have the following relations between cosine, secant and cosecant of an angle from trigonometry.

$\sec A=\dfrac{1}{\cos A}~~\textup{and}~~\csc A=\dfrac{1}{\sqrt{1-\cos^2 A}}.$

Therefore,

$\sec A=\dfrac{11}{3}$

and

$\csc A=\dfrac{1}{\sqrt{1-\frac{9}{121}}}=\dfrac{1}{\sqrt{\frac{112}{121}}}=\dfrac{11}{4\sqrt 7}.$

Thus, the correct option is (a) sec A = 11 over 3.
