<u>Answer</u>
1
<u>Explanation</u>
The general equation of a wave is ;
y = a sin(kX+Ф)
Where a represent the amplitude, 360/k represent the period of the wave and Ф represent the phase angle.
∴ In the equation y = 1 sin 2x,
Amplitude = 1
Answer:
Part 1: y= 49
Part 2: y=12
Step-by-step explanation:
Part 1: The y is going up by 7, so if you add 7 to 42, you get 49
Part 2: The y is going up by 4, so if you add 4 to 8, you get 12
-0.027 is the answer, basically you would just count out the zeros behind the decimal since it's 100, you would place one zero to create the "hundredths" place
To solve for the longest side, the hypotenuse, you have to use the pythagorean theorem. It will be 10^2 + 9^2 = c^2. 100 + 81 =c^2.
c^2 = 181 so c = sqrt(181).
to find sin of A do opposite/hypotenuse which gives you 9/sqrt(181)
to find cos of A do adjacent/hypotenuse which gives you 10/sqrt(181)
