Answer:

z^5

Step-by-step explanation:

z^8  * z^-3

Since we are multiplying exponents and the bases are the same, we can add the exponents

z^(8-3)

z^5

Ksju [112]

5.75+3(.50) because it’s 5.75 and then add .50 3 times to get 7.75. Meaning you can play 3 games...

Hope that helps

Which statement is correct about relations and functions?
aniked [119]

Definition 1: A relation is any subset of a Cartesian product. For instance, a subset of A\times B, called a "binary relation from A to B," is a collection of ordered pairs (a,b) with first components from A and second components from B, and, in particular, a subset of A\times A is called a "relation on A."

Definition 2: A function is a relation that associates each element x of a set X to a single element y of another set Y (possibly the same set). A function is uniquely represented by its graph which is the set of all ordered pairs (x, f (x)).

From these definitions you can see that every function is a relation from X to Y, but not via versa (because you can consider relation \{1\}\times \{2,3\} - here for one x exist two y).

Answer: Correct choice is B.

The function f(x)=5(2)^x was replaced with f(x)+k , resulting in the function graphed below. what is the value of k?
xxTIMURxx [149]
Since adding a constant to a function simply moved the graph upwards by that amount, solve f(x) for any value and see how much the graph given is different from that value of y...the simplest way in this case may be to simply find f(0) which is:

5*2^0=5

Clearly the graph at x=0 is at y=-2  so we can see that k is:

5+k=-2 so

k=-7
