At the moment a hot cake is put in a cooler, the difference between the cake's and the cooler's temperatures is 50\degree50°50,

Len [333]

Answer:

$D(t)=50\cdot (0.8)^{t}$

Step-by-step explanation:

The equation for exponential decay function is given as:

$D(t)=a(1-r)^{t}$

where:

D(t)= difference in temperature t=time

r=rate of change

a =initial value of the temperature

From the given problem:

Initial Temperature,a=50°C

Rate of Decay,r= $\frac{1}{5}$

Therefore the function for the difference in temperature is given as:

$D(t)=50(1-\frac{1}{5})^{t}$

$D(t)=50\cdot (\frac{4}{5})^{t}$

We can convert $\frac{4}{5}$ to decimal and write the function as:

$D(t)=50\cdot (0.8)^{t}$

Factor using GCF or monomialpfactoring: w3 + 3w w3(w + 3) W(w2 + 3) 3W(1)

liraira [26]

Answer:

w(w² + 3)

Step-by-step explanation:

Given the expression

w³ + 3w

Since w is common to the terms w³ and 3w, we will factor it out from the expression as shown;

w³ + 3w

w(w²)+ 3(w)

w(w² + 3)

This gives the required expression
