Answer: 76 m^2
Step-by-step explanation:
Answer:
In 5 complete rotations it will go 7.85 m.
Step-by-step explanation:
Diameter = O.5 m
Clare: 5/(2 x 3.14) = 0.795 m
Andre: 5/(4 x 3.14) = 0.397
C = 3.14 x 0.5 = 1.57 x 5 =7.85m
D. 4×6 is 24. 15×5 is 75. They add up to 99, which is below 100
Answer:
189 million
Step-by-step explanation:
The exponential formula can be written from the given information. We are given a growth factor of 187/183 that applies to an 8-year time period. That means we need to scale the time by a factor of 8 if we're going to use that growth factor:
p = a·b^t . . . . . . . initial value 'a'; growth factor b
p = 183(187/183)^(t/8) . . . . where t is years after 1993
For 2004, 11 years after 1993, the estimated population is ...
p = 183(187/183)^(11/8) ≈ 189 . . . million
The population estimate for 2004 is 189 million.
_____
<em>Additional comment</em>
The annual growth factor is (187/183)^(1/8) ≈ 1.00271. That is, it is about 0.271% per year.
