Answer:
Step-by-step explanation:
a) To find the length of diagonal XT, we can use the distance formula to get 
Since this is a rectangle, XT=YW, meaning YW=10 as well.
b) The area of a rectangle is given by length times width. The length is |-3-5|=8, and the width is |-2-4|=6. So the area is (8)(6)=48.
c) The perimeter is just 2(8+6)=28.
I am guessing Jack is 51 and Lacey is 17.
The domain of a function are the possible input values of the function.
<em>The domain of the function is (d) Whole numbers</em>
First, we identify the start and end values of x on the graph.
We have:

The graph has no end; so:

This means that the domain of the graph is 
The number of times one can visit the pool cannot be decimal.
Hence, the domain of the function is whole numbers

I'm pretty sure it's -3/2
Answer:
A. d = 59°
Step-by-step explanation:
We know that the 3 angles added up together are a straight line or 180°. Therefore,
m∠d° = 180 - (57 + 64)
