Cindy is 72 inches long. Imagine it like a right triangle. Her shadow is the base, she is the side, and the distance between her head and the end of the shadow is the diagonal line connecting the two. Use the Pythagorean theorem to find how tall cindy is.
a²+b²=c² a=21, the length of the shadow
b= ? cindy's height
c= 75, the distance from her head to the edge of the shadow
21²+ b²=75²
441 +b² = 5625
-441 -441
------ -------
0 5184
b² = 5184
√b² =√5184
b= 72
hope it helps
Answer: 16 ft
Explanation:
You can determine the lengths of each segment by subtracting the coordinates of the adjacent points.
1) From (2,5) to (8,5): 8 - 2 = 6
2) From (8,5) to (8,3): 5 - 3 = 2
3) From (8,3) to (2,3): 8 - 2 = 6 (as expected as this is congruent to the first
4) From (2,3) to (2,5): 5 - 3 = 2 (as expected as this is congruent to the second).
The total length of the border or perimeter is equal to the sum of all the sides:
perimeter = 6 + 2 + 6 + 2 = 16
Therefore the answer is 16 ft

Answer:
f (3) is equal to 31
Step-by-step explanation:
f (3) means that x is equal to 3 [hence f (x) ---> f (3)]
Plugin 3 into all the x values to solve:
4(3)^2 - 2(3) + 1
4(9) - 6 + 1
36 - 6 + 1
30 + 1
31
f (3) is equal to 31
Answer:
So I would say your answer is..............A
Step-by-step explanation:
For most places, global warming will result in more frequent hot days and fewer cool days, with the greatest warming occurring over land. Longer, more intense heat waves will become more common. Storms, floods, and droughts will generally be more severe as precipitation patterns change
Also, A is correct because lets say you put an ice cube in the sun...okay well if it keeps getting hotter and hotter multiply ice cubes into ice caps. Well same thing will happen. It will melt causeing water from the ice caps. Which will result into more water. Which will cause water to go above sea level!
Hope this helps!!!
