If a boat with a value of $23, 000 depreciates at a rate of 18% per year, what is the value
Naily [24]

Using an exponential function, it is found that the value of the car after 5 years will be of $8,527.

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

A(t) = A(0)(1 - r)^t

In which:

  • A(0) is the initial value.
  • r is the decay rate, as a decimal.

For this problem, the initial cost and the decay rate are given as follows:

A(0) = 23000, r = 0.18.

Hence the value of the boat after t years is given as follows:

A(t) = A(0)(1 - r)^t

A(t) = 23000(1 - 0.18)^t

A(t) = 23000(0.82)^t

The value after 5 years will be of:

A(5) = 23000(0.82)^5 = 8527

The value of the car after 5 years will be of $8,527.

Find the exact values of the following,giving your answers as fractions
Vsevolod [243]

Answer:

(a) 3^{-2}=\frac{1}{9}

(b) 4^{-3}=\frac{1}{64}

(c) 2^{-6}=\frac{1}{64}

Step-by-step explanation:

To find the exact value in fractions of the followings:

Exponents also called powers its a way of expressing a number multiplied by itself by a certain number of times.

Using a^{-m}= \frac{1}{a^m}                   .......[1]

(a)

Fraction represents a part of a whole or more generally, any number of equal parts.

3^{-2} = \frac{1}{3^2}=\frac{1}{3\times 3}=\frac{1}{9}         [ Using [1]]

(b)

4^{-3} = \frac{1}{4^3} =\frac{1}{4\times 4\times 4}=\frac{1}{64}          [ Using [1]]

(c)

2^{-6} = \frac{1}{2^6} =\frac{1}{2\times 2\times 2\times 2\times 2\times 2}=\frac{1}{64}          [ Using [1]]

Help me with these 2 questions please
Margaret [11]

Answer:

1st one= B 25 cents

2nd one= D 2 miles

Step-by-step explanation:

1.

8x3=24

6/24=25

= 25 cents

2.

1.6 km= 1 mile

so 1/2 of a mile =

0.8 km

1/4 of an hour = 15 minutes

0.8km= 15 minutes

15x3= 45  minutes

0.8km x 3= 2.4km

2.4km = 2 miles

hope it helps hunney xx

Find the equation!!!!!! asap
My name is Ann [436]

Answer:

y=\frac{1}{36}x^2

Step-by-step explanation:

The focus of the parabola is (0,9)

and the directrix is y=-9.

The equation of this parabola is given by:

x^2=4py

The vertex of this parabola is at the origin.

The value of p is the distance from the vertex to the focus.

p=9-0=9

The equation of the parabola is

x^2=4(9)y

x^2=36y

Or

y=\frac{1}{36}x^2
