Answer:
A) A(p(t)) = 25πt²
B) 314 square units.
Step-by-step explanation:
Part A)
Flow of paint can be expressed by the function:
p(t) = 5t
Area of the pattern is expressed as:
A(p) = πp²
Since area is given in terms of p, we can use the expression of p to express the area of pattern in terms of time(t). Using the value, we get:
A(p(t)) = π (5t)²
A(p(t)) = 25πt²
Part B)
We have to calculate the area of the pattern after time t. Substituting the value of t in above expression, we get:
A(p(2)) = 25 x 3.14 x 4 = 314 square units.
Therefore, the area of spilled paint after 2 minutes will be 314 square units.

Answer:
1. The red one
2. 60%
3. 18,57%
Step-by-step explanation:
I use the way to calculate the percentage in question 2 and 3
2. (6:10)x100%
3. (13:7)x100%
5.5 miles over 2 hours--> 5.5/2= 2.75 miles per hour was his average walking speed. 5.5 miles over 2.5 hours --> 5.5/2.5= 2.2 miles per hour on the return trip meaning that his average speed was (2.75-2.2= 0.55) 0.55 miles per hour lower on the return trip
Answer:
Let's consider each of the statements.
1. Six below zero.
⟹ Any number below zero will be negative. So, the value will be 
____________________
2. The opposite of six.
⟹ The opposite of 6 wil be negative 6. The value again will be
____________________
3. Negative six.
⟹ Negative six in numerical form is
____________________
4. The absolute value of six.
⟹ Here they've asked the absolute value of 6 which will be 
____________________
⏩ So, the statement which doesn't have the same value will be ⇻
