For this case we have that by definition the growth of a population is a function of the form:
Where,
- <em>a: initial population
</em>
- <em>b: growth rate
</em>
- <em>x: number of years
</em>
We observe then that the function is of the exponential type.
Answer:
C) Exponential
38%, 0.4, 0.5, 5/8 is that ordered from least to greatest
Let x be the first integer, then
:
x + (x+1) + (x+2) + (x+3) + (x+4) + (x+5) = 519
:
6x + 15 = 519
:
6x = 504
:
x = 84

Our sequence is
:
84, 85, 86, 87, 88, 89
:
The third integer is 86
Answer:
6/25 km in 1 min; or 0.24 km/min
Step-by-step explanation:
The info about Angel is not necessary.
Jayden runs 3 laps in 5 mins
Each lap is 2/5 km, so Jayden runs 3 x (2/5 km) in 5 min = 6/5 km in 5 min.
Distance = rate x time
6/5 km = rate (5 min)
We want to isolate r (rate), so divide both sides by 5 min
6/5 km ÷ 5 min = r
6/5 km (1/5 min) = r
6/25 km/min = r (notice how the units worked out correctly to km/min)
So, Jayden runs 6/25 km in 1 min.
