Answer
Area=20,5yr^2
Step-by-step explanation:
d1=13+13=26yd
d2=7,5+7,5=15yd
P=(d1+d2)/2
P=(26+15)/2
P=41/2
P=20,5yr^2
1.yes
no
yes
2.false
true
false
3.more
4. 14 hours gives her more than $100
For 3, it is an isosceles triangle and it is an acute triangle.
Answer:
1.U={1,2,3,4,5}
A={2}
B={2,3}
C={4,5}
2.U={1,2,3,4}
A={1,2}
B={2,3}
C={4}
Step-by-step explanation:
We are given that
and 
are different sets
1.We have to construct a universe set U and non empty sets A,B and C so that above set in fact the same
Suppose U={1,2,3,4,5}
A={2}
B={2,3}
C={4,5}

{2,3,4,5}
={2}
{2,3,4,5}={2}
={2}
={2}
Hence, 
2.We have to construct a universe set U and non empty sets A,B and C so that above sets are in fact different
Suppose U={1,2,3,4}
A={1,2}
B={2,3}
C={4}

={2,3,4}
={1,2}
={1,2}
={1,2}
{2,3,4}={2}
Hence, 
Answer:
1. b. 4/7
2. c. 3
Step-by-step explanation:
To find the slope
m = (y2-y1)/(x2-x1)
m= (7-3)/(5 - -2)
= (7-3)/(5+2)
= 4/7
m = (y2-y1)/(x2-x1)
m= (5-2)/(2 - 1)
= 3/1
