Answer:
a) = 4/9 b) -20/21
c) -77/6 d) 39/22
Step-by-step explanation:
For P(t) = 920*1.06^(2t), the current population is 920, the percentage growth rate is 6% semiannually, and the population in 4 years will be 920*1.06^8 = 1466.
Selection B is appropriate.
_____
The 2 in the exponent means the growth factor 1.06 is applied twice for each increment of t, that is, twice in 1 year (semiannually).
Answer:
B.) Communative
Step-by-step explanation:
The communitive property is when changing the order of the operands does not change the result. For this equation if you had it as 7 * 5 it would equal 35 and when it is 5 * 7 it would still equal 35.
6x1=__________________
Answer would then be c
Answer:
t = 2.25
Step-by-step explanation:
To find t, divide each side by 4.
9 = 4t
Divide 9 by 4:
2.25 = t
So, t = 2.25
