I don’t know if this is right or not but m < ABD + m < BDC = 90
The colony doubles every hour, the population is equal to
p = 2^t
<span>Where t </span><span>is the time in hours.</span>
We are able to see this because:
2^0 = 1
2^1 = 2
2^2 = 4
Notice that the x coordinate of the graph corresponds to the time, and the y coordinate corresponds to the population.
<span>Thus at t = 9
</span>p = 2^t
p = 2^9
p = 512.
The correct answer is 512.
Answer:
A
Step-by-step explanation:
Answer:
(b) 1:9
(c) 1:8
Step-by-step explanation:
(b) x*y : kx*ky, so 1:k² with k=3 is 1:9
(c) Assuming the rectangles get a z dimension, the volumes would have a ratio of xyz : xkykzk = xyz : xyzk³ = 1 : k³. With k=2 that is 1:8. But the z was never introduced so this is a bit inconclusive.
Answer:
<h3><u>C≈131.97cm</u></h3>
A Area
1386cm²
Using the formulas
A=πr²
C=2πr
Solving forC
C=2√πA
=2·√π·1386
≈131.97344cm
