Answer: The answer is y=-4/3x-10.
Step-by-step explanation:
-6=-4/3(-3)+b
-6=4+b
-4 -4
-10=b
y=-4/3x-10
5. 623. Just split the shape into two. then find the area of two figures that you created. Then add.

Answer:
150 bags
Step-by-step explanation:
Given the total area:
The area will be:
=75*50
= 3750 square feet
As it is given that one bag covers 25 square feet. To find the total number of bags we have to find how many 25s will be in 3750 square feet.
So,
Total number of bags = 3750 / 25
= 150 bags
Hence, total number of bags that will be used are 150 ..
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
