For this case we have that the expression in its exact form is the same, that is:
If it is expressed in decimal form we have:
If we want equivalent expressions, we must first mention the following property of powers and roots:
Then, we can rewrite the expression as:
Answer:
Answer:
The sine and cosine are complementary functions.
Step-by-step explanation:
In a right angle triangle, the two angle angle are complementary.
This means they add up to 90 degrees.
One special property of the right angle triangle is that, the sine of angle is equal to the cosine of its complement.
On the unit circle we can also create a special right angle triangle with its hypotenuse being one unit.
The complementary property still applies to this right angle triangle.
For wool u bought 3 and for cotton i am pretty sure 3 and 1 left over
Answer:
47
Step-by-step explanation:
3(7x-3) -2(4x-2) when x=4
3(7*4-3) -2(4*4-2)
3(25)-2(14)
75-28=47
the answer is 47
Current Account Balance = $1,624.35
Initial Deposit = $975
Interest Rate (Simple) = 3.7% simple interest
Interest Earned = Current Account Balance - Initial Deposit
⇒ Interest Earned = $1,624.35 - $975
⇒ Interest Earned = $649.35
Now the Formula for Simple Interest is:
Simple Interest = ×, where P is the initial deposit, R is the rate of interest and T is the time period
⇒ 649.35 =
⇒ T =
⇒ T = 18
Hence, Jeremiah has had the account for 18 years.
