30 -35 points Workings please. 1. Find the equation of the tangent to the curve with equation
3x^2 + 2x - 5 at the point where x = - 2

2. At what point(s) on the curve with equation
y = 5x^3 is the tangent parallel to the line with equation 15x - 4y + 8 = 0 ?

Thank you for any help.
30 points (there are other questions differentiation similar on my profile.)

i think it is 70

step-by-step explanation:

1 and 0

its line 2 i just added the rest or else it wouldn't let me answer

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
