Based in your question where as the oil is pumped continuously from the well at a rate proportional to the amount of the oil left in the well. so the answer of the following questions are:
A.1 is to 200,000
B.5 years
Your answer is C c:
First, split the angle into two angles where the values of the six trigonometric functions are known. In this case, 105, can be split into 45+60 (cos (45+60))
Use the sum formula for cosine to simplify the expression. The formula states that cos (A+B) = - (cos (A) cos (B) + sin (A) sin (B)).
The exact value of cos(60) is 1/2. So multiply 1/2 to cos (45) - sin (60) times sin (45).
The exact value of cos (45) is the square root of 2 over 2
(1/2) ⋅ (<span>√2/</span>2) - sin (60) <span>⋅ sin (45)
</span>
Value of sin (60) is <span>√3/2
</span>(1/2) ⋅ (√2/2) - √3/2 ⋅ sin (45)
exact value of sin (45) is √2/2
(1/2) ⋅ (√2/2) - √3/2 ⋅ √2/2
all that equals √2/4 - √6/4
Answer:
-$34.725
Step-by-step explanation:
Given the question :
The price of one share of a company's stock declined $13.89 every day for 2.5 days. What was the stock's total decline in price? Which estimate uses compatible numbers to estimate the problem? What is the exact answer?
Price declination per day = $13.89
Number of days = 2.5 days
Stock's total declination :
(Declination in price per day × number of days)
( - $13.89 × 2.5) = - $34.725
- Principal=P=4000
- Time=T=2years
- Rate of interest =R=36
Interest be I
Now
Final value=4000+2880=6880
