f(x)    = 2x^5 + x^3 + 10. Find the derivative of this.

f ' (x) = 10x⁴ + 3x²

The hearts are the same ....the one by your name is your total.

y / g = 7/2    re-arrrange to

2  /  7   * y   =  g     can you finish from here ?

d / r = 12 /15     re-arrange to :

15 / 12  * d  = r

15/12  * 4 = roses

25 min * 2 2/5 = 25 * 2.4   minutes

I think you get them when you post or answer a question......or when another account holder 'upvotes' your answer .....   'guest' accounts cannot upvote your answers.....but YOU can upvote yourself one heart for good answers.....you can also be 'downvoted'   which may happen if you rpovide nothing but an answer with no derivation or an incorrect answer....    I just 'upvoted' your last post ..... see?

Nope ....  two minus signs make a ' + '   sign     81 - -9    = 81 + 9 = 90

6 x sqrt (90) = 56.92              so answer would be   57
