Answer:
1/2
Step-by-step explanation:
if you look at a unit circle, sin(\pi/6) is
so cos of (\pi/6/2) would be \pi/3, and cos of (\pi/3) is 1/2
Answer:
Missing co-ordinate for the ordered pair is 
Y-intercept is 
X-intercept is 
Step-by-step explanation:
The number of a certain company's video stores can be approximated by the linear equation

where
is the number of stores and
represents the number of years after 1990.
To find the missing co-ordinate for the ordered pair solution 
For the ordered pair, we are given the
value which is =7 i.e 7 years after 1990. Thus we will plugin
in the linear equation to get the
value which is number of stores after 7 years from 1990.



Thus the ordered pair is 
To find y-intercept which is the point where the line touches the y-axis, we would plugin
in the equation as the x-coordinate is 0 at y-axis.



Thus y-intercept is at point 
To find x-intercept which is the point where the line touches the x-axis, we would plugin
in the equation as the y-coordinate is 0 at x-axis and thus for 

Subtracting both sides by 4682.


Dividing both sides by -264


∴ 
Thus x-intercept is at point 
Answer:
#6 is 1001
#8 is x=1312
Step-by-step explanation:
6. 11*13*7= 1001
8. 32*41=x
x= 1312
Answer:
16 / C
Step-by-step explanation:
-4 x -4 = 16
4 x 4 = 16
two negatives cancel out when multiplying, that is why it equals 16*
Answer:
2/5
Step-by-step explanation:
The slope would be the change in y over the change in x which is 2 units up and 5 units to the right, so the answer is 2/5. hope this helps:)
