120÷4=30. this is the rate per 15 minutes.
30×3=90. this is the rate for 45 minutes.
91+90=181$

Hope this helped:)

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

Need help how can i do this?

TEA [102]

ANSWER

$\boxed {c. \: \: 33}$

EXPLANATION

The relationship between the number of faces, number of vertices and number of edges of a solid shape is given by the formula,

$F+V-2=E$

It was given that, F=24 and V=11.

We substitute these values into the formula to obtain,

$24+11-2=E$

We solve for E to get,

$33=E$

or

$E = 33$

Therefore the correct answer is C
