The derivative of f(x) = 3x⁴ − 5x² + 2x is:
f'(x) = 12x³ − 10x + 2
#### 12x³ − 10x + 2### Question 1
An industrial designer is working on a new product line, aiming to reduce production waste. The goal is to recycle 75% of all materials used. If the production initially uses 1,200 kilograms of materials, how many kilograms of waste material are expected after recycling?
Calculate the amount of materials recycled:
\( 75\% \times 1200 \text{ kg} = 0.75 \times 1200 = 900 \text{ kg} \)
Calculate the remaining waste material:
\( 1200 \text{ kg} - 900 \text{ kg} = 300 \text{ kg} \)
A structural engineer is designing a building with 10 floors. Each floor requires 500 cubic meters of concrete. To enhance sustainability, 20% of the concrete used on each floor is replaced with recycled material. How much recycled material is used in total?
Calculate the concrete replaced with recycled material per floor:
