Step-by-step explanation:
<u>Trigonometric Identities</u>
<u>Trigonometric ratios</u>
where:
- is the angle
- O is the side opposite the angle
- A is the side adjacent the angle
- H is the hypotenuse (the side opposite the right angle)
Using the trig ratio formulas for cosine and sine:
Therefore, using the trig identities and ratios:
The shift from the agriculture economy to consumer markets led to the free enterprise system.
Answer:
B
Step-by-step explanation:
I believe the answer is B because if we multiply the top equation by 6, we get 48x + 30y = -42, and if we multiply the bottom equation by -5, we get
35x - 30y = 20. So now, if we add it all together, then the positive 30y and negative 30y cancel out aka it equals 0, and thus the variable y is gone, satisfying the requirement that the problem asks for ("Which of these strategies would eliminate a variable...").
I hope this helped, and if it's correct, I'd appreciate if you marked my answer as Brainliest :)
Given that Naomi deposited some money into a savings account that is compounded quarterly at an interest rate of 6%.
Now we have to identify if the compounded quarterly interest rate is same as monthly interest rate or not.
We know that future value of compound interest formula is given by:
Where P= initial deposit
r = yearly rate of interest = 6%= 0.06
n = number of compounding per year
For quarterly n=4 because there are 4 quarters in 1 year.
For monthly n=12 because there are 12 months in 1 year.
t= number of years.
We know that there are 3 months in 1 quarter so to convert quarterly rate into monthly rate, we need to divide quarterly rate by 3 so we get
monthly rate = 6%/3= 2 %
while the given interest rate is 1.5% which is different than obtained value 2%
Hence Naomi is thinking WRONG that this quarterly rate is the same as a monthly interest rate of 1.25%.
Correct monthly interest rate will be 2% as shown above.
