The after 29 minutes 38 seconds, Jane and Kinsley will be 47 miles apart if they are moving in the exact opposite directions.

<h3>What is distance?</h3>

A numerical representation of the distance between two items or locations called distance. A physical length or an approximation based on other considerations in physics or common usage can be referred to as distance.

Let's suppose the at time t they are 47 miles apart.

We know, distance = speed×time

(44+51)t = 47

t = 47/95

t = 0.494 hours

t = 29 minutes 38 seconds

Thus, the after 29 minutes 38 seconds, Jane and Kinsley will be 47 miles apart if they are moving in the exact opposite directions.

What is the coefficient of the third term in the binomial expansion of (a + b)6? 1 15 20 90

Sholpan [36]

Answer: 15

Step-by-step explanation:

(r+1)th term of $(a+b)^n$ is given by:-

$T_{r+1}=\ ^nC_r(a)^{n-r}b^r$

For $(a+b)^6$ , n= 6

$T_3=T_{2+1}=\ ^6C_2(a)^{6-2}(b)^2\\\\$

$=\ \dfrac{6!}{4!2!}a^4b^2\ \ \ [^nC_r=\dfrac{n!}{r!(n-r)!}]\\\\=\dfrac{6\times5\times4!}{4!\times2}a^4b^2\\\\=3\times5a^4b^2\\\\ =15a^4b^2$

Hence, the coefficient of the third term in the binomial expansion of $(a+b)^6$ is 15.

marusya05 [52]

Answer:

$(f\circ g)(2)=16$

Step-by-step explanation:

By definition composite function would be:

$(f\circ g)(x)=f(g(x))$

Then, if g(2)=3 and f(3)=16, therefore for f(g(x)):

$\begin{gathered} (f\circ g)(x)=f(g(2))=f(3) \\ \text{Hence,} \\ (f\circ g)(2)=16 \end{gathered}$

<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Suppose another company offers a special banquet price of $4,000 for 150 people.

Then the special is cheaper than Bella's price.

Then the correct option is B.

More about the linear system link is given below.
