64,500 would be the answer
Answer: 8,100 cm^2
Step-by-step explanation: Area = S^2 so each side is sqrt(900) = 30cm
A square 3 times bigger has sides 30cm*3 = 90cm. The area for that square is 90^2 = 8,100 cm^2

Answer:
-2
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= ( 3-9)/(0- -3)
= (3-9)/(0+3)
= -6/3
= -2
Continuous exponential growth formula is given by:
A=Pe^(rt)
where A is the current amount
P=initial amount
r=rate
t=time
the time taken for the sample to double will be found as follows:
let:
P=x
A=2x
r=0.025
thus
2x=xe^(0.025t)
2=e^0.025t
introducing natural logs we get:
ln 2=0.025t
t=ln2/0.025
t=27.73 hours
