Sn=A1(1-r^n)/(1-r)
Sum of a finite geometric series formula
We know the sum, number of terms and rate, so you plug those in.
-255=A1(1-(-4)^4))/(1-(-4)
-255=A1(1-256)/5
-255=A1(-255)/5
-1275=A1(-255)
5=A1
Hope this helped! Let me know if you have any questions.
So I’m assuming you’re saying that 1 cm=6 m so if the kitchen is 4 cm in the drawing it has to be scaled up by 6 for each centimeter. So 4*6=24 so the kitchen is 24 meters long. Hope this helps!
Answer:
p1 = 70 deer
p2 = 98 deer
Step-by-step explanation:
We use the population growth expression:

which in our case renders:

Therefore, after 1 year the population would be:

giving a total of 70 deer
and after two years, it would be:

Answer: C, In Step 2 the expression for y should be subsituted in the other equation.
Answer:
875
Step-by-step explanation:
