Answer: $2215
Step-by-step explanation:
For the past 5 weeks, Mandy adds $291 each week to her account. This gives $291×5= $1455
Money received on birthday= $313
Money started with in the account= $527
Total money in Mandy's account will be= $1455+$313+$527 = $2295
The total amount in Mandy's account is $2215
1) 2x² -5x+12
2) x² +7x+10
3) 3x² +5x-2
Answer:
4x / (2x^2+1)
Step-by-step explanation:
g(x)=ln(2x^2+1)
Using u substitution
u= 2x^2 +1
du = 4x dx
g'(x) = d/du ( g(u) du)
We know that the derivative of ln(u) = 1/u since this is always positive
= 1/ u* du
Substituting x back into the equation
g'(x) = 1/(2x^2+1) * 4x
= 4x / (2x^2+1)
I think it is 40 because add 5+9=14+3=17+6=23+4=27+5=32+6=38+9=47-4=43-3=40
