Use appropriate formulas and show your work to manually decompose the signal f(t) = 5cos(2t) • cos(3t + π/4) into a linear combination (i. e., a sum of constant multiples) of sinusoidal functions, and determine the amplitude, frequency, and phase shift of each component after decomposition. note: each of the sinusoidal functions in your answer must be of the form a sin(bt + c) where a > 0, b > 0, while c can be positive, zero, or negative.

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
