Answer:

1st term = 14

2nd term = 29

3rd term = 44

Step-by-step explanation:

1st term = 3 x (5x 1) - 1

= 3 x 5 - 1

= 15 - 1 = 14

2nd term = 3 x ( 5 x 2 ) - 1

= 3 x 10 - 1

=30 - 1 = 29

3rd term = 3 x (5 x 3 ) - 1

= 3 x 15 - 1

= 45 - 1 = 44

F(x)=e*1/x<br>Calculate f'(x)

Murljashka [212]

Answer:

$\huge\boxed{f'(x)=-\dfrac{e^\frac{1}{x}}{x^2}}$

Step-by-step explanation:

$(e^x)'=e^x\\\\\bigg[f\bigg(g(x)\bigg)\bigg]'=f'\bigg(g(x)\bigg)\cdot g'(x)\\\\\left(\dfrac{1}{x}\right)'=-\dfrac{1}{x^2}\\\\====================$

$f(x)=e^\frac{1}{x}=\left(e^\frac{1}{x}\right)'\cdot\left(\dfrac{1}{x}\right)'=e^\frac{1}{x}\cdot\left(-\dfrac{1}{x^2}\right)=-\dfrac{e^\frac{1}{x}}{x^2}$

I need help with this 2 step equation word problem. I don't need to answer it, I just need to get the equation.

pshichka [43]

So it would be 4x (x meaning the price of each pizza) + 3 for the delivery charge. The equation is 4x + 3. That would be the price of all pizzas plus delivery charge :)
