Answer:
1) d. 2400
2) d.4200
Step-by-step explanation:
As per given data:
F(x) represents number of fish
x represents number of weeks
Relation between F(x) and x is given as
F(x)= 500 (1.2)x
Now part 1:
How many fish are in the pond after 4 weeks=?
x=4
Putting in given equation F(x)= 500 (1.2)x
F(x)= 500(1.2)(4)
= 2400
Now part 2:
How many fish are in the pond after 7 weeks?
x=7
Putting in given equation F(x)= 500 (1.2)x
F(x)= 500(1.2)(7)
= 4200 !
I think its 24% because .24 x 50 is 12 but I could be doing it wrong, sorry I can't say for sure.
Answer:
X3+76+22x the 3 goes on top of the x
Step-by-step explanation:
x3-24+22x+100
x3+(-24+100)+22x
x3+76+22x
