Given:
Oil flow: n(t) = 7t where t is time and n = how far the oil is spreading
Area of the circular pattern the oil is forming:
A(n) = πn²
<span>Part A: Find the area of the circle of spilled oil as a function of time, or A[n(t)]
A[n(t)] = </span>π (7t)² = π * 49 * t²
<span>How large is the area of spilled oil after 8 minutes?
n(t) = 7t </span>→ 7 * 8 = 56
A(56) = 3.14 * 56² = 9,847.04 square units
or
A[n(t)] = π (7t)²
A[n(8)] = 3.14 * (7*8)² = 3.14 * 3,136 = 9,847.04 square units
Answer:
for the first one: x = -25/3 or -8.333333
for the second one: x = 29-8y/9
Step-by-step explanation:
for the first one:
add 8 to both sides 3x=-33 + 8
simplify -33+8 to -25
divide both sides by 3
which gives you -25/3 or 8.333333
for the second one:
subtract 8y from both sides 9x=29-8y
divide both sides by 9
which gives you x= 29-8y/9
B. 4.8 but i think it should be 5.3 not 4.8 but the most logic is b
