Answer
Find out the what was the price of the stereo .
To prove
Let us assume that the price of the stereo be x .
As given
Consumer Math The sales tax in the town where Amanda lives is 7%.
7% is written in the decimal form
= 0.07
As given
Amanda paid $35 in sales tax on a new stereo .
Than the equation becomes
x × 0.07 = 35
solving the above
x = $ 500
Therefore the price of the stereo is $ 500 .
Hence proved
Check the picture below.
now, the "x" is a constant, the rocket is going up, so "y" is changing and so is the angle, but "x" is always just 15 feet from the observer. That matters because the derivative of a constant is zero.
now, those are the values when the rocket is 30 feet up above.
I think it would be A.) but at the same time i think it's wrong
It would be t=0.8, mainly bc you subtract two from six , that reduces it to four
then you divide four by five and it should give you your answer
and to chack your work put .8 where t was and solve
