Answer:
#3.) The initial value of 16 gal at x = 5 minutes means that 16 gallons of water was present 5 minutes after the barrel started leaking.
#4.) Find how many minutes until the barrel is empty of water.
Let y = 0, to solve for time x.
0 = (-2/5)*x + 18
(2/5)*x = 18
x = (5/2)* 18 = 5*9 = 45 minutes
Up to and after 45 minutes, the barrel is empty of water.
Step-by-step explanation:
#2.)
minutes: 5, 10, 15, 20
water(gal): 16, 14, 12, 10
Find slope: slope m = (14 - 16)/(10 - 5) = -2/5
y - 10 = (-2/5)*(x - 20)
y - 10 = (-2/5)* x + 8
y = (-2/5)*x + 18
rate of change slope means that for every minute 2/5 gallons of water is lost

Answer:
yes 5 is right
Step-by-step explanation:
16 times larger is the new area when compared to the original.
Given that, the length of each side of the square is quadrupled.
We need to find how many times larger is the new area when compared to the original.
<h3>What is the area of a square?</h3>
A square is a closed two-dimensional shape with four equal sides and four equal angles. The four sides of the square form the four angles at the vertices. The sum of the total length of the sides of a square is its perimeter, and the total space occupied by the shape is the area of the square. The formula to calculate the area of a square is a².
Let the length of each side of the square be x.
Then the length of each side of the new square will be 4x.
Now, the area of the original square = x²
The area of the new square = (4x)² = 16x²
So, the new square = 16 × the original square
Therefore, 16 times larger is the new area when compared to the original.
