Answer:
Fig A
Step-by-step explanation:
in fig A, we can see that the subset that represents "trees", lies inside the subset that "has leaves". Hence in figure A, we can say that "All trees have leaves" or "if it is a tree, it has leaves"
in fig B however, we see that "has leaves" is inside of "trees", this means that the area in-between "has leaves" and "tree" represents the subset that there are trees without leaves. This is in contradiction to the statement "if it is a tree, it has leaves", hence this is not the answer.
Question number 5. is 9
question number 6. is 6
Answer:
12 in.
Step-by-step explanation:
You have to use the Pythagorean theorem for this problem. Since we are solving for DE, we do:
5 squared + b squared = 13 squared
25 + b squared = 169
Isolate the b:
25 - 25 + b squared = 169 - 25
b squared = 144
Find the square root of 144 = <u>12</u>
<u>(The formula for the Pyathagorean theorem is a squared + b squared = c squared) </u>
1/2 y +6 = x
y=2 (x-6)
= 2x-12
f^-1 (x)= 2x-12
Answer:
Radius = 5.75
Circumference = 36.13
Step-by-step explanation:
Here we have the diameter, and the radius is half of the so 5.75. For the circumference, we can use the formula C=2πr
