They are (r+t), e, (r+t) e, and 1 .
R(t) = 3t ; where t represents the time in minutes and r represents how far the paint is spreading.
A(r) = πr²
Part A:
A[r(t)] = π (3t)² = 3.14 * 9t² = 28.26t²
Part B:
r(10) = 3(10) = 30
A(r) = 3.14 * 30² = 3.14 * 900 = 2,826 square unit

Answer:
y +1 = -3(x -3)
Step-by-step explanation:
The given point is (3, -1), and the given slope is -3. The form suggests you want the point-slope form of the equation for the line:
y -k = m(x -h) . . . . . . . . line with slope m through point (h, k)
Using the given values, the equation is ...
y -(-1) = -3(x -3)
y +1 = -3(x -3)
