42 because he won 35 so 5 times 7 equals 35 so you would multiply the other side by seven and 6 times 7 is 42
You have
.. f'(u) = sec(u)^2
Putting in u = g(x) = x^9, this becomes
.. f'(g(x)) = sec(x^9)^2
You know
(f(g(x))' = f'(g(x))*g'(x) . . . . . chain rule
From previous results, this is
.. sec(x^9)^2*9x^8
Answer:
I can try to answer.
Step-by-step explanation:
1. 23
2. 25
3. week 4 is 29, and week 3 is 23
29-23=6
4. week 5 and 7 because on week 4 it was 29, it dropped to 25 on week 5. On week 6 it was 37, then dropped to 34 on week 7.
Im not rlly sure about 5, but ill answer it if I figure it out.
40
Try dividing 400 by ten you'll get 40 (or just remove a zero or decimal point to the left when dividing by 10)
Answer:
$15
Step-by-step explanation:
$3 correspond is the 20% discount of the total price.
If the total price is x then you can express the discount as:
0.20x = 3
x = 3/0.20
x = 15
