Not sure
te rate is r
for decay, it is
A=P(1-r)^t
r=rate
P=present amount
dunno what b is
but I guess
A=28000(1-0.13)^t
A=28000(0.87)^t
I would guess the decay factor would be 0.87
Answer:
60
Step-by-step explanation:
the question is based on similarity and enlargement
firt thing put the velues to ratio form;8;20
simplify to obtain2:5 as your linear scale factor...
if 5:150
2=?
2*150/5=60
Answer:
x = 12
Step-by-step explanation:
I believe that the two tangents are equal to each other so 2x would be equal to x + 12, so you would subtract x from x + 12 and get x equals 12. I think...
Let b>a
b=a+13
a+b=35, using b found above we have:
a+a+13=35
2a+13=35
2a=22
a=11, and since b=a+13
b=24
So the two numbers are 11 and 24
