Answer:
see explanation
Step-by-step explanation:
the volume (V) of a cylinder is calculated using the formula
V = area of base × height
here the base is a circle with radius r = 2x²y
area of base = πr² = π × (2x²y)² = π × 4y² = 4y²π
V = 4y²π × 3x³
= 12y²π
Answer:
No Solution
Step-by-step explanation:
Jason starts riding a bike 1 mile from the station.
Shawn starts biking 2 miles from the station.
For Jason to reach Shawn, he needs to go at a higher speed. However we know that they are going at the same constant speed. Then they will never meet.
To prove it we propose the following system of equations. Where x is the hours and y is the distance in miles.
For Jason we have:
For Shawn
.
We want to know when Jason and Shawn are at the same distance.
Then we write the following eqution and clear x:
Equality is not satisfied. Therefore, it has no solution.
I mean Jason and Shawn will never be the same distance
X = 6
8(6) + 2 → 48 + 2
48 + 2 = 50
Answer:
x = 0
Step-by-step explanation:
if 2y + x = 4
we can assume that y = 2
if y - 3x = 2
it means 2 - 0 = 2
therefore x = 0
