1. The growth rate equation has a general form of:
y = A (r)^t
The function is growth when r≥1, and it is a decay when
r<1. Therefore:
y=200(0.5)^2t -->
Decay
y=1/2(2.5)^t/6 -->
Growth
y=(0.65)^t/4 -->
Decay
2. We rewrite the given equation (1/3)^d−5 = 81
Take the log of both sides:
(d – 5) log(1/3) = log 81
d – 5 = log 81 / log(1/3)
d – 5 = - 4
Multiply both sides by negative 1:
- d + 5 = 4
So the answer is D
Answer:
w=p/2-t
Step-by-step explanation:
Answer: A
Step-by-step explanation: Take the biggest number and work backwards.
It seems that you are looking for the yield of the shares of stocks after they were sold.
To solve,
yield =( current total amount- previous total amount) / previous amountwherecurrent amount = $9.9/share*700share+ $18previous=$9.29/share*700 share
yield=[ (9.9*700)+18] -(9.29*700)/(9.29*700) x 100
yield= 6.8%
Shares of stocks yield = 6.8%
