Answer:
Answers are given below.
Step-by-step explanation:
a) one-to-one correspondence between the set of positiveintegers and that set.
Whenever we have one to one correspondence with positive integers, the set is countable and here infinite.
b) integers divisible by 5 and not 7
..This set is all integers divisible by 5 but not by 7. This is a discrete set and hence countable and infinite.
c) the real numbers with decimal representationsconsisting of all 1’s
-- This cannot be counted and hence uncountable but infinite.
d) the real numbers with decimal representationsconsisting of all 1’s or 9’s
-- This is also uncountable but infinite.
Answer:
{
}
Step-by-step explanation:
We are given that
In a freefall skydive, a skydiver begins at an altitude during free fall =10,000 feet
The skydiver drops towards earth at a rate=175 ft/s
The height of the skydiver from the ground can be modeled using the function

We have to find the domain of the function for this situation.
When t=0
Then ,
From given graph we can see that the value of t lies from 0 to 50.
Therefore, the domain of the function for this situation is given by

}
7x7=4 so if u carry the 9 it will be 33
-8/7
6- -2= 8
3- -4=7
rise over run the slope of K is 7/8
perpendicular is the negative inverse of the slope so it ends up as -8/7
Answer:
XZ=12 in
Step-by-step explanation:
area of a rhombus is A=pq/2
where p=WY=15.5 and A=93 and q=XZ
93=15.5(XZ)/2
93(2)=15.5(XZ)
186/15.5=XZ
XZ=12 in
