The equation Upper A left parenthesis t right parenthesis equals 2000 e Superscript 0.055 t gives the balance after t years of a

Pachacha [2.7K]

Answer:

a) Rate of change of amount

$A'(t) =110e^{0.055t}$

b) &170.79

c) 0.21

Step-by-step explanation:

We are given the following in the question:

The balance is given by the equation:

$A(t) =- 2000e^{0.055t}$

where t is the time in years and the initial investment is $2000 when compounded continuously.

a) Rate of change of amount

$\dfrac{d(A(t))}{dt} = \dfrac{d}{dt}(2000e^{0.055t})\\\\\dfrac{d(A(t))}{dt} = 2000e^{0.055t}\times 0.055\\\\\dfrac{d(A(t))}{dt} =110e^{0.055t}$

b) We have to find the value of A'(8)

$A'(t) =110e^{0.055t}\\A'(8) = 110e^{0.055(8)} = 170.79$

Interpretation:

The future value of 9 year investment of $2000 will be $170.79 more than the future value of 8 year investment.

c) Comparison

Approximation = $171

Actual change = $170.79

Difference =

$\text{Approximation - Actual change}\\=171 - 170.79\\=0.21$

Thus, the error is 0.21

Emily attends a Film Festival. The admission fee is $10. Each movie ticket cost $5 each. Emily wants to determine how many movie

Rashid [163]

Answer:

Emily can buy 6 movie tickets after paying the admission fee

Step-by-step explanation:

Let x be the number of movie tickets

If each movie ticket costs 5 dollars then the cost of x movies will be 5x

And the admission fee will be a constant.

She has $40 in total

So the equation can be written as

$10+5x = 40\\5x = 40-10\\5x = 30\\\frac{5x}{5} = \frac{30}{5}\\x = 6$

Hence,

Emily can buy 6 movie tickets after paying the admission fee

A car travels 20 feet in 1/5 second. At this same speed, how many feet will it travel in three seconds?

MrRissso [65]

<span>if it is travelling 20 feet in 1/5 of a second that means that in 1 second (which is 5 times as much as 1/5 of a second) it will do 5 times 20 feet hence 100 feet. Then in 3 seconds it will do 300 feet</span>
