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:

$f(t)= 27000 * 0.965^t$

How would you use estimation to evaluate this expression 10.2 x [(2x3.7)+8]

Goryan [66]

Round off the decimals to a sensible number. So 3.7 would be 4 and 10.2 would be 10. In this case, it would be (2 × 4 + 8) × 10 which is 160.

An electric utility company determines the monthly bill for a residential customer by adding an energy charge of 7.32 cents per

Sedaia [141]

Answer:

$y(x) = 0.0732x + 17.32$

Step-by-step explanation:

The equation for the monthly charge has the following format

$y(x) = ax + b$

In which y(x) is the cost in function of the number of kilowatt-hours used(x), a is the price of each killowatt hour and b is the fixed(base) charge.

Base charge of $17.32 per month.

This means that $b = 17.32$

charge of 7.32 cents per kilowatt-hour

Our answer is in dollars. Each dollar is 100 cents. So 7.32 cents is $a = 0.0732$

Write an equation for the monthly charge y in terms of x, the number of kilowatt-hours used.

$y(x) = ax + b$

$y(x) = 0.0732x + 17.32$
