Answer & Step-by-step explanation:

First, we will multiply 5 by 28 to find out the total number of ages in the room.

5 * 28 = 140

Now, we will multiply 6 by 29 to find out the total number of ages in the room after the new person comes in.

6 * 29 = 174

Now, in order for us to find the age of the new person, then we will subtract 140 from 174.

174 - 140 = 34

So, the person that entered the room is 34 years old.

The exponential decay graph shows the expected depreciation for a new boat, sell g for $3500, over 10 years.
Alisiya [41]
Okay, the exponential function is
g = a^{x}
The start price of it in t=0 is 3,500, as we can see on the graph. Then, the function becomes
g = 3500^{x}
Let's see at t=2, where the price is g=2000:
2000 =  3500^{x}
Take natural logarithm:
ln 2000 = ln  3500^{x}
x*ln 3500 = ln 2000
x = \frac{ln 2000}{ln 3500} = 0.93
So, the difference between t=0 and t=2 is
x_{t=0}  -  x_{t=2}  = 1 - 0.93 = 0.07
And then we get the change of x in one year equal to 0.035.
So, the final equation is
g =  3500^{1-0.035t}
You can insert any t and see that it is correct, for example t=7
