Answer:
2root3
Step-by-step explanation:
root27= root 3 x root9
= root3 x 3 -root3
= 3root3-1root3
= 2root3
Answer:
The Domain interval notation is -2 < t < 98
Step-by-step explanation:
The given parameters are;
The time at which the plant began spouting = 2 days before Amy bought it
The number of days the plant was with Amy = 98 days
The maximum height reached by the plant = 30 centimetres
Given that the height of the plant is represented by the function h(t), where h is in centimetres and t is the number of days from the time she bought the plant
Therefore, we have;
At t = -2, h = 0
At t = 98, h = 30
The slope of the function is therefore;
m = (30 - 0)/(98 - (-2)) = 0.3 cm/day
The equation of the function is therefore;
h - 30 = 0.3 × (t - 98)
h = 0.3·t -29.4 + 30 = 0.3·t + 0.6
h(t) = 0.3·t + 0.6
At h(t) = 0, t = -2
At h(t) = 30, t = 98
The interval notation of the domain is therefore, -2 < t < 98.

Answer:
no - total is $57.12
Step-by-step explanation:
64.00 - 15% = 64.00 x 15% = 9.60
64.00 - 9.60 = 54.40
54.40 x 5% = 2.72
54.40 + 2.72 = 57.12
