I cant see all the question but this is how you find the derivative of your function using the product rule.
Here you use the extension of the product rule to 3 factors which we'll write as:-
f(x), g(x) and h(x):-
Derivative = f'(x) g(x) h(x) + f(x) g'(x) h(x) + f(x) g(x) h'(x)
(3x - 1)(x + 4)(2x - 1)
derivative = 3(x + 4)(2x - 1) + (3x + 1)(1)(2x - 1) + (3x - 1)(x + 4)(2)
= 3(x + 4)(2x - 1) + (3x + 1)(2x - 1) + 2(3x - 1)(x + 4)
Answer:$17.40
Step-by-step explanation:
This is a very simple question. First since 70% is the amount of money removed, we do 100-70=30
30% is the price that remains. Change that into a fraction 30/100 and then multiply the original cost
30/100*58=17.4
The answer is $17.40
She had none left. if she only had a meter and then used a meter there would be none left.
The unit rate in this scenario is the number of ounces per steak/in one steak.
72 oz/2 steaks= 36 oz per steak
Final answer: 36 oz per steak
