ElenaW [278]

Answer:

(-6,4)

Step-by-step explanation:

add the x coordinates of point A and B(take x coordinate of B as X),then divide the sum of 2 and equal it to 2 which is the x coordinate of the midpoint.

then repeat the same procedure for the y coordinates ,take the sum of y corrdinates divide by 2 and equal to 8.

IM SO DUMB I NEED HELP
alexdok [17]

Answer:

76.0m^2 (you have to have the .0 since it says to round to the nearest <em>tenth</em>)

Step-by-step explanation:

The formula for the surface area of a rectangular prism is:

A=2(wl+hl+hw)

So just plug in the values.

Height= 4

Width=2

Length=5

A=2((2)(5)+(4)(5)+(4)(2))\\A=2(10+20+8)\\A=2(38)\\A=76m^2

DVD Video Rentals (Refer to Example 3.) The func-
Neporo4naja [7]

Answer:

(a)\ V = \{(N,30),(R,37),(S,17)\}

(b)

Domain = \{N,R,S\}

Range = \{37,30,17\}

Step-by-step explanation:

Given

V(R) = 37,\ V(N) = 30,\  V(S) = 17

Solving (a): Set of ordered pair

A function y = f(x) is represented as (x,y)

So, the ordered pair of V is:

V = \{(R,37),(N,30),(S,17)\}

Order the alphabets in increasing order

V = \{(N,30),(R,37),(S,17)\}

Solving (b): The domain and the range

In a function \{(x_1,y_1),...,(x_n,y_n)\}

The domain and the range are represented as:

Domain = \{x_1,x_2....x_n\}

Range = \{y_1,y_2....y_n\}

So, we have:

Domain = \{N,R,S\}

Range = \{37,30,17\}
