The population of osaka japan declined at an average annual rate of 0.05% for five years between 1995 and 2000. If the populatio
n of osaka was 11,013,000 in 2000 and it continues to decline at the same rate, predict the population in 2050
1 answer:
Answer:

Step-by-step explanation:
we know that
The equation of a exponential decay function can be written as

where
y ---> is the population of Osaka japan
x ---> the number of years since 2000
a ---> is the initial value or y-intercept
r is the rate of change
we have


substitute


Predict the population in 2050
so

For x=50 years
substitute in the equation

Answer:
4.1 sec
Step-by-step explanation:
h(t)=-3.2t^2+12.8t+1
h(t)=-3.2(t^2-4t)+1
h(t)=-3.2(t^2-4t+4-4)+1
h(t)=13.8-3.2(t-2)^2
For the ball to touch ground, h(t)=0.
13.8-3.2(t-2)^2=0
(t-2)=2.0766
t=4.07≈4.1 sec.
Answer:
2/35
Step-by-step explanation:
original equation:q+1/7=1/5
subtract both sides by 1/7
q=1/5-1/7
q=2/35

16
Because...
4 cats/ 5dogs = x cats/ 20 dogs
Therefore you can conclude it is 16 cats in total
Step-by-step explanation:
First, sub in the ordered pair to find y int
(7) = -1(-2) + b
7 = 2 + b
b = 5
So the equation in y int form is
y = -1x + 5
This when convert to stardard form is
x + y = 5
