Answer:
y= 407.54654 ft
Step-by-step explanation:
This is an exponential decay functions
y = ab^x where a is the initial value and b is ( 1 - rate of decay)
a = 520
b = 1- 3%
y = 520 ( 1- .3) ^x
y = 520 ( .97) ^x
We want x to be 8 weeks
y = 520 ( .97) ^8
y= 407.54654 ft
The answer would be A.-(+8 1/4)
There’s this website math papa and it gives the answer step by step anyway here you go this is your answer x=1
Answer:
A 30 in
Step-by-step explanation:
The ratio of the sides must be equal if they are proportional
36 x
------- = ---------
12 10
Using cross products
36*10 = 12*x
360 =12x
Divide each side by 12
360/12 = 12x/12
30 =x
