Step-by-step explanation:
3(t+5) = 9
3t+15 = 9
3t = -6
t = -2
2(f-7) = -10
2f - 14 = -10
2f = 4
f = 2
-(c - 9) = 4
-c + 9 = 4
-c = -5
c = 5
-6(2t + 8) = -84
-12t - 48 = -84
-12t = -36
12t = 36
t = 3
-10 (s + 2) = -57
-10s - 20 = -57
-10s = -37
s = 3.7
7(3w + 8)/3 = -9
By cross multiplication,
7(3w + 8) = -27
21w + 56 = -27
21w = -83
w = -3.95
35/5 = (F - 32)/9
7 = (F - 32)/9
By cross multiplication,
63 = F - 32
63 + 32 = F
95 = F

Answer:
6 years
Step-by-step explanation:
we know that
The equation of a exponential growth is equal to

where
y ----> is the population
x ---> is the number of years since now
a ---> is the initial value or y-intercept
r ---> is the rate of change
we have


substitute


For y=19,600
substitute in the exponential equation and solve for x


apply log booth sides



Answer:
Step-by-step explanation:
The number is 1/2, and 1/2 squared is 1/4.
