Answer:
Part 4) 
Part 10) The angle of elevation is 
Part 11) The angle of depression is 
Part 12)
or 
Part 13)
or 
Step-by-step explanation:
Part 4) we have that

The angle theta lies in Quadrant II
so
The sine of angle theta is positive
Remember that

substitute the given value




Part 10)
Let
----> angle of elevation
we know that
----> opposite side angle theta divided by adjacent side angle theta

Part 11)
Let
----> angle of depression
we know that
----> opposite side angle theta divided by hypotenuse


Part 12) What is the exact value of arcsin(0.5)?
Remember that

therefore
-----> has two solutions
----> I Quadrant
or
----> II Quadrant
Part 13) What is the exact value of 
The sine is negative
so
The angle lies in Quadrant III or Quadrant IV
Remember that

therefore
----> has two solutions
----> IV Quadrant
or
----> III Quadrant
Answer:
The company's profit in 2007 was 11.088 millions
Step-by-step explanation:
This is a compound interest problem where the initial amount is 8.8 million, the interest rate is 6% and the time period is 4 years and it gets compounded yearly. So we can use the compound interest formula, that is given by:
A = P*(1 + r/n)^(n*t)
Where A is the final amount, P is the initial amount, r is the rate, t is the total amount of time and n is the number of times it gets compounded in one year. We can now use all the values that were given to us to find out the profit of the company.
A = 8.8*(1 + (0.06))^(4) = 8.8*(1.06)^16
A = 8.8*1.26 = 11.088 millions
So the company's profit in 2007 was 11.088 millions
Answer:
63m^11 no^12
Step-by-step explanation:
Dont know if thats o or and zero but I solve it by using o..if it was a zero then comment that so I can redo it anyways heres the explanation
(7nm^5 o^2) × (-3m^3 o^5)^2
7m^5 no^2) ×(-3m^3 o^5) ^2
(7m^5 no^2) × (3m^3 o^5)^2
7m^5 no^2 × (3m^3 o^5) ^2
7m^5 no^2 × 9m^6 o^10
63m^11 no^12
