The amount of radioactive uranium changes with time. The table below shows the amount of radioactive uranium f(t) left after tim
aniked [119]

Answer:

f(t) = 100(0.25)^t

Step-by-step explanation:

The general exponential function is,

f(t)=ab^t

The points given in the table are,

(0,100),(0.5,50),(1,25)

Putting (0,100),(1,25) in the general equation, we get

\Rightarrow 100=ab^0

\Rightarrow a=100

And

\Rightarrow 25=ab^{1}

\Rightarrow ab=25

Putting the value of a,

\Rightarrow 100b=25

\Rightarrow b=0.25

Now the exponential function becomes,

f(t) = 100(0.25)^t

A business owes $8000 on a loan. Every month, the business pays 1/2 of the amount remaining on the loan.
sveticcg [70]
Here is the answer to the given problem above. Given that the business owes $8000 on a loan and every month, it pays 1212. So for the first month, the remaining is 6,788. On the second month is 5,576, and on the third month, it is 4,364. In the fourth month, the remaining would be 3,152, and in the fifth month is 1,940. Therefore, on the sixth month, if the business pays 1,212 still, the remaining would be $728 only. Hope this answer helps.

A woman's salary is increased by 20%. A week later her company loses one of its best customers and her salary is reduced by 35%.
Nuetrik [128]

Answer:

$5472

Step-by-step explanation:

Set up a reverse ratio for each change:

4446/x = 65/100

65x = (4446) x (100)

65x = 444,600

x = 6840

Before her salary was reduced by 35%, she was earning $6840.

x/6840 = 20/100

100x = (6840)(20)

100x = 136,800

x = 1368 = 20%

$6840 - $1368 = $5472
