It would be around 6 months to accumulate $1000 in your account
I am going to simplify the top before simplifying the rest.
tan = sin/cos, so tan * cos simplifies down to sin in the numerator. which leaves sin/sin which equals 1.
to make a long story short the answer is 1
The answer is 729, -2187
because you multiply each number by -3
It is -3/2, 2/10 - 5/8 = -3/2
The slope is 3 y-intercept is 7 and the equation would be y=3x+7
