The Hobbits are building a watchtower so they can prepare to battle in case trolls decide to attack them. One Hobbit will always

be on the lookout and the Hobbits will prepare for battle as soon as the trolls are visible. The time, TTT, in minutes, that the Hobbits have to prepare for the attack of trolls kkk meters away is given by the function T(k)=\dfrac{k}{80}T(k)= 80 k ​ T, left parenthesis, k, right parenthesis, equals, start fraction, k, divided by, 80, end fraction. The visibility, VVV, in meters, that the Hobbits have from an mmm meter watch tower is given by the function V(m)=50mV(m)=50mV, left parenthesis, m, right parenthesis, equals, 50, m. Find an explicit expression that models the amount of time the Hobbits have to prepare for a troll attack given that the watchtower is mmm meters tall.

Answer:

An explicit expression is equal to 3m/8

Step-by-step explanation:

we know that

Function T gives the time the Hobbits have to prepare for the attack, T(k), in minutes, as a function of troll's distance, k, in meters

so

T(k)=\frac{k}{80}

Function V gives visibility from the watchtower, V(m), in meters, as a function of the height of the watchtower, m, in meters

so

V(m)=50m

Find the composite figure T(V(m))

That will give the time the Hobbits have to prepare for the troll attack as a function of the height, m, of the watchtower

Substitute the variable k in the function T by the function V(m)

T(V(m))=\frac{50m}{80}

simplify

T(V(m))=\frac{5m}{8}

therefore

An explicit expression is equal to 3m/8

What is the method of comparing Coefficient ​
Svetllana [295]

Answer: In mathematics, the method of equating the coefficients is a way of solving a functional equation of two expressions such as polynomials for a number of unknown parameters. It relies on the fact that two expressions are identical precisely when corresponding coefficients are equal for each different type of term.
