Answer:
1. f(0) = 501170
2. decreasing
3. 2% decrease
4. 302438
Step-by-step explanation:
In 1995 x=0
f(x) = 501170(0.98)^0
f(0) = 501170
The population is decreasing since we are multiplying by .98 ^x
.98 is less than 1 so it is getting smaller each time.
1 -.98 = .02
It is decreasing by 2 % each year
2020-1995 =25 years
f(25) = 501170(0.98)^25
=302438.41862
Rounding to the nearest whole number
302438
Answer:
16
Step-by-step explanation:
Always do multiplication first:
6*4 = 24
(-2)(4) = -8
Note: A negative times a positive always equals a negative
After multipying, do addition:
24+ (-8) = 24-8 = 16
The answer is the first one A. sss Postulate
Answer:
B. 28, 32, 36 millions
Step-by-step explanation:
Given:
P(t) = 24 + 0.4t
Where,
P(t) = population in millions
t = number of years
✔️Value of the population when t = 10:
Plug in t = 10 into P(t) = 24 + 0.4t
P(t) = 24 + 0.4(10)
P(t) = 24 + 4
P(t) = 28 million
✔️Value of the population when t = 20:
Plug in t = 20 into P(t) = 24 + 0.4t
P(t) = 24 + 0.4(20)
P(t) = 24 + 8
P(t) = 32 million
✔️Value of the population when t = 30:
Plug in t = 30 into P(t) = 24 + 0.4t
P(t) = 24 + 0.4(30)
P(t) = 24 + 12
P(t) = 36 million
Answer:
see attached
Step-by-step explanation:
Your equation is in slope-intercept form, ...
y = mx + b . . . . line with slope m and y-intercept b
with m = -1/2 and b = 3.
This tells you the point y=3 on the y-axis is one point on the graph. (That is the y-intercept.) It also tells you the line decreases 1 unit for each 2 units to the right.
m = rise/run = -1/2 ⇒ rise = -1 for run = 2
So, another point that is 2 right an 1 down from (0, 3) is (2, 2). Your line will go through these two points. Plot them and draw the line through them.
