A restaurant purchased kitchen equipment on January 1, 2017. On January 1, 2019, the value of the equipment was $14 comma 550

timama [110]

Answer:

$\frac{dV(t)}{dt} =$ - 1675.38

Step-by-step explanation:

In 2017, the vakue of the kitchen equipment was $14550

V(0)=$14550

Its value after then was modelled by $V(t)=14550e^{-0.158t$

We are required to find the rate of change in value on January 1, 2019

$V(t)=14550e^{-0.158t$

$\frac{dV(t)}{dt} =\frac{d}{dt}14550e^{-0.158t$

$\frac{dV(t)}{dt} =14550 \frac{d}{dt}e^{-0.158t$

$\\Let u= -0.158t,\frac{du}{dt}=-0.158$

$\frac{dV(t)}{dt} =14550 \frac{d}{du}e^u\frac{du}{dt}$

$\frac{dV(t)}{dt} =14550 X -0.158 e^{-0.158t}=-2298.9e^{-0.158t}$

In 2019, i.e. 2 years after, t=2

The rate of change of the value

$\frac{dV(t)}{dt} =-2298.9e^{-0.158X2}$

= $\frac{dV(t)}{dt} =-2298.9e^{-0.316}$ = - 1675.38

1. What is the sum of the polynomials?

AysviL [449]

Answer:

1. 2m+2n+7

2. 3m-2

3.-2m+2-2n

Explanation:

To find the sum of given polynomials (m+n+3) +(m+n+4)

Firstly, open the parenthesis we will get m+n+3+m+n+4

After simplification we will get 2m+2n+7

To find the difference of given polynomials (10m-6)-(7m-4)

Firstly, open the parenthesis we will get 10m-6-7m+4

After simplification we will get 3m-2

Again to find the difference of the polynomials (4m-5)-(6m-7+2n)

Firstly, open the parenthesis we will get 4m-5-6m+7-2n

After simplification we will get -2m+2-2n
