Answer:

Option C is right.

Step-by-step explanation:

Resultant vector is the sum of two vectors.

i.e. addition of horizontal component and addition of vertical components.

For example, if ai+bj is one vector and ci+dj be another vector,

resultant vector = a+ib+c+id

= (a+c)+i(b+d)

i.e. option c is right

Answer:

$D(t)=50(0.8)^t$

Step-by-step explanation:

We are given that

Initially the difference between the cake's and the cooler's temperature ,a=50 degree Celsius

$r=\frac{1}{5}/min$

We have to find the function that gives the temperature difference in degrees Celsius D(t).

We know that

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

Substitute the values

$D(t)=50(1-\frac{1}{5})^t=50(1-0.2)^t$

$D(t)=50(0.8)^t$

This is required function that gives the temperature difference in degrees Celsius.
