Answer:
The Domain.
Step-by-step explanation:
That is the Domain. For example the domain of the function √x is the set
{x : x ≥ 0}.
Answer:
67
Step-by-step explanation:
The angle with x in it is a vertical angle to the other one labeled & the right angle put together.
Therefore:
48 + 90 = 2x + 4
Solve for x:
138 = 2x + 4
138 - 4 = 2x + (4-4)
134 = 2x
134/2 = 2x/2
X = 67
Hope this helps! Have a great day!
Most likely you are expected to recognize that side lengths 2, 3, 5 will result in a "triangle" of zero area (looks like a line segment).
The appropriate choice is
(5, 3, 2)
_____
Some authors write the triangle inequality as a + b ≥ c for any assignment of a, b, c to side lengths. The "or equal to ..." allows the triangle to have zero area (looks like a line segment). Other authors insist the inequality not include the "or equal to" case. It looks like your text's author is in the latter camp.
To find the volume, you would use the formula V=1/3 pi times radius squared times the height. So, you would multiply 1/3 x 3.14 x 5.62^2 x 7.5. This equals approximately 248 cubic inches.
