Answer:
[0, 7]
Step-by-step explanation:
We want the height to be greater than or equal to 32 ft, so ...
704 +16t -16t^2 ≥ 32
t^2 -t -42 ≤ 0 . . . . . . . . . . . subtract 32, divide by -16
(t -7)(t +6) ≤ 0
This inequality will be true for values of t between -6 and +7. Since we're only concerned with times t ≥ 0, the appropriate solution interval is ...
0 ≤ t ≤ 7 . . . . [0, 7] in interval notation
The answer is 3b
Step-by-step explanation: I searched up ways to learn abc math and it said guess so yea
Three line segments can form a triangle if the length of the longest segment is greater than the sum of the lengths of the shorter segments.
They can form a triangle.
Now if c is the length of the longest side and a and b are the lengths of the shorter sides, then:
- if
, the triangle is right
- if
, the triangle is acute
- if
, the triangle is obtuse
The triangle is obtuse.
The answer is D.
