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:
$19.26 or $19.
Step-by-step explanation:
Sold DVD for 50% more of the purchase price of $12, so:
12 + 50/100 * (12) = 12 + 6 = 18.
The customer will pay 7% tax on $18.
18 * (1.07) = $19.26
Answer:
Step-by-step explanation:
Use the slope-intercept formula:
m is the slope and b is the y-intercept. Use the slope formula first:
Rise over run is the change in the y-axis over the change in the x-axis. Plug in the coordinates:
Simplify parentheses (two negatives makes a positive):
Simplify:
The slope is 
. Insert into the equation:
Now, to find the y-intercept, take one of the points and substitute for the x and y values of the equation:
Solve for b, the y-intercept. Simplify parentheses:
Add 
to both sides:
Simplify:
The y-intercept is 
. Insert this into the equation:
Finito.
