Answer:
x = -16
Step-by-step explanation:
subtract the two over first so x/4 = -4
multiply both sides by 4
x = -16
Answer:
Step-by-step explanation:
The population P of a certain city can be modeled by
P=19000e0.0215t
where T represent the number of years since 2000.
When t=1 the year is 2001
when t =2 the year is 2002. This means that
When t=0 the year is 2000
To determine the year when the population will be 40,000 , we will substitute P = 40,000 and solve for t. It becomes
40000 = 19000e^0.0215t
40000 / 19000 = e^0.0215t
2.105 = e^0.0215t
Take ln of both sides
0.7443 = 0.0215t
t = 0.7443/0.0215
t = 34.62
Approximately 35 years
So the year will be 2035
Answer: (-2,1)
Step-by-step explanation:
The point (1,2) is in quadrant 1.
When rotated 90 degrees counter clockwise, it moves to quadrant 2.
The new point becomes (-2,1)
