Answer:

(A) cos \theta = -0.9664

cos \theta =-0.9659

Step-by-step explanation:

Given

sin \theta = 0.259 \:and;\\ tan \theta = -0.268

Sine is Positive and Tangent is Negative in Quadrant II.

In Quadrant II, Cosine is also Negative.

sin \theta = 0.259 \\\theta=arcsin 0.259=15.01^\circ\\$Therefore in Quadrant II:\\cos \theta =-cos\:15.01^\circ =-0.9659

Closest Option is A.

Prove that (a-b) x (a+b)=2a x b is true.<br> (a and b are vectors)
Anon25 [30]
(a-b) X (a+b)
=  aXa - bXa +aXb -bXb (distributing)

Now, cross product of a vector with itself = 0
so, aXa = 0, bXb = 0

Also, aXb = - bXa

so,
(a-b) X (a+b) = 0 + aXb + aXb + 0
= 2aXb

hence, proved :)

- One night a theater sold 548 movie tickets. An adult's ticket costs $6.50 and a child's ticket cost $3.50.
Natasha_Volkova [10]

Answer:

Step-by-step explanation:

Let X= each ticket for adults and Y= each ticket for kids

x+y=548

6.50x+3.50y=2881

subtract x from each side leaving you with y= -x+548

Plug in for Y

6.50x+3.50(-x+548)=2881

6.50x - 3.50x + 1918= 2881

3x+1918=2881 ....subtract

3x=963 .....divide by 3

X= 321 tickets for adults

321+y=548 ...subtract 321

Y=227 childrens tickets
