Answer:
1) 2x-5 2) -10/x^2
Step-by-step explanation:
Use power rule and constant rule for the first one:
1) f(x)=x^2-5x^1+1 (x^n)'=nx^(n-1) and (c)'=0
f'(x)=2x^1-5(1)x^0+0
f'(x)=2x-5(1) x^0=1
f'(x)=2x-5
Use just power rule for last one after a rewrite
2) f(x)=10/x
f(x)=10x^(-1) now use power rule
f'(x)=-10x^(-2) =-10/x^2
Hi! This is just a simple multiplication problem!
So he recieves 7 dollars for each vacuum cleaner therefore we must multiply 7 by the amount he sells.
7*30 =210
7*35=245
7*40 280
That means he will earn somewhere between 210 dollars - 280 dollars
Hope this helped!
