Answer:
dy/dx = 18x – 6
Step-by-step explanation:
y = (3x – 1)²
Take derivative using power rule and chain rule:
dy/dx = 2 (3x – 1) × 3
dy/dx = 6 (3x – 1)
dy/dx = 18x – 6
You can check this answer by simplifying y before taking the derivative.
y = 9x² – 6x + 1
dy/dx = 18x – 6
Twenty ten thousandths, Four thousandths, Three hundredths,Five tens,Seven Ones
Answer:
see below
Step-by-step explanation:
1a) -5(1) + 11 = 6
1b) -5(-3) + 11 = 26
1c) -5(0) + 11 = 11
1d) -5(1.2) + 11 = 5
1e) f of x equals negative 5x plus eleven
7 7/8 + 5 13/16
We must have a common denominator between the 2 fractions.
8 can go into 16.
7 x 2 = 14
8 x 2 = 16
The fraction is now 14/16 rather than 7/8.
14/16 + 13/16 = 27/16 = 1 11/16
7 + 5 = 12
12 + 1 11/16 = 13 11/16.
The final sum is 13 11/16.
Have you tried sketching this situation?
x is the length of the side of his original office. If he adds 15 ft, then the area, A, would be x times (x+15). 15x represents the floor area of the addition.
