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.
If you get confused by logarithms, here's an easier way to think about this problem: What power of 2 equals 128? Well, we know 2^3 = 8, then 2^4 must equal 16. Doubling every times, we get 2^5 = 32, 2^6 = 64 and 2^7 = 128. So, the value of log₂128 is 7.
Divide -9 from both sides which results in a flip of the sign (dividing or multiplying a negative to both sides results in a flip of the sign!)
You now have
y =< -8

Step-by-step explanation:
To Calculate the percentage Increase
<u>Step 1</u>: Subtract the old value from the new value
1.8 mg - 1.2 mg = 0.6 mg
<u>Step 2:</u> Divide the difference by the Old Value
<u>Step 3: </u>Multiply by 100
