.
Step-by-step explanation:
The area of the algae colony is a function of the radius r (meters), so
.
The radius of the circle formed by the algae colony is a function of time t (in minutes), so
. So,

Answer:
(2x+1)(x+7)
Step-by-step explanation:
Guess and Check
(2x+7)(x+1) = 2x^2+9x+7. NOPE
(2x+1)(x+7) = 2x^2+15x+7. YES
The answer is 98 degrees relative to the axis(probably u or v axis ) due to the fact that complementary angles are 90 degrees or it could be 8 degrees if you take the u or v axis as a constraint axis
