Answer:
the cost function is Cost=7000 m*$ /R + 50.265 $/m² * R²
Step-by-step explanation:
then the cost function is
Cost= cost of side area+ cost of top + cost of bottom = 2*π*R*L * 5$/m² +
π*R² * 8$/m² + π*R² * 8$/m²
since the volume V is
V=π*R²*L → V/(π*R²)=L
then
Cost=2*π*R*V/(π*R²) * 5$/m² + π*R² * 8$/m² + π*R² * 8$/m²
replacing values
Cost=2*700 m³ /R * 5$/m² + π*R² * 16$/m² = 7000 m*$ /R + 50.265 $/m² * R²
thus the cost function is
Cost=7000 m*$ /R + 50.265 $/m² * R²

Answer: $252.68
Step-by-step explanation:
Find 12.75% of 249 by using formula T= A + (A•I/100)
T=249+(249•12.75)/100)= 31.75 (taxes)
Then add taxes to room cost;
249+31.75= 280.75
Then you’d apply the coupon of 10% by using; Discount = Original Price x Discount %/100
Discount = 10% or 10/100=0.1
Discount = 280.75 x 0.1
= $28.08
Now you’d find the final price by;
Final Price = Original Price - Discount
Final Price = 280.75 - 28.075
Final Price = $252.68
4x^2 - 64
= 4(x + 4) (x - 4)
