write an exponential formula of the form f (t)= a×b^t to represent the following situation. assume t is in years. The beginning
nika2105 [10]

Answer:

f(t)= 27000 * 0.965^t

Step-by-step explanation:

Given

a = 27000 -- initial

r = 3.5\%

Required

The exponential equation

The exponential equation is

y =ab^t

Where

b=1 -r

We used minus, because the rate decreases..

So, we have:

b=1 -3.5\%

b=1 -0.035

b=0.965

So:

y =ab^t

y = 27000 * 0.965^t

Hence:

f(t)= 27000 * 0.965^t

Simplify<br>-6√20+2√45+7√5 <br><br>show Woking out to prove ans please​
Dmitry_Shevchenko [17]

Answer:

\sqrt{5}

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

Simplifying the radicals

\sqrt{20} = \sqrt{4(5)} = \sqrt{4} × \sqrt{5} = 2\sqrt{5}

\sqrt{45} = \sqrt{9(5)} = \sqrt{9} × \sqrt{5} = 3\sqrt{5}

Thus

- 6(2\sqrt{5}) + 2(3\sqrt{5}) + 7\sqrt{5}

= - 12\sqrt{5} + 6\sqrt{5} + 7\sqrt{5}

= \sqrt{5}
