A container of oil has spilled on a concrete floor. The oil flow can be expressed with the function n(t) = 7t, where t represent
nadezda [96]
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

Solve:3x-8y=-33<br><br> solve:9x+8y=29<br><br> show work please
TiliK225 [7]

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

(x+y)(x+6y) pls help me solve question pls and pls also give explanation if possible
steposvetlana [31]

Step-by-step explanation:

= (x + y)(x + 6y)

= x \times x + x \times 6y + y \times x + y \times 6y

=  {x}^{2}  + 6xy + xy + 6 {y}^{2}

=  {x}^{2}  + 7xy + 6 {y}^{2}
