Dave uses a computer to control his robots. Suppose Robot A starts from the origin and moves 4 units upward. Meanwhile, he

moves his Robot B starting from the point P1 (5, -3) to P2 (5, 4).

Plot the movement of robots in a graph and find what is asked.

a. What is the coordinate of the current location of Robot A?

b. How far is Robot B from its starting point?

c. How far is Robot A from Robot B?

Can someone help me? I am troubled with this

Exercise: counting committees 0.0/2.0 puntos (calificable) we start with a pool of n people. a chaired committee consists of k≥1 members, out of whom one member is designated as the chairperson. the expression k(nk) can be interpreted as the number of possible chaired committees with k members. this is because we have (nk) choices for the k members, and once the members are chosen, there are then k choices for the chairperson. thus, c=∑k=1nk(nk) is the total number of possible chaired committees of any size. find the value of c (as a function of n ) by thinking about a different way of forming a chaired committee: first choose the chairperson, then choose the other members of the committee. the answer is of the form c=(α+nβ)2γn+δ. what are the values of α , β , γ , and δ ?
