I don’t know what day is it
Answer:
{x | -1 < x ≤ 2}
Step-by-step explanation:
Interval given in the notation of (a, b) denotes,
Upper limit at 'b' and lower limit at 'a'
Sign () denotes the interval between a and b exclusive of the numbers a and b.
Interval given as [a, b] represents,
a = lower limit
b = higher limit
Notation of [] show the interval inclusive of these numbers.
Given set in the question is (-1, 2]
Here (-1) is the lower limit and 2 is the upper limit.
(] notation shows exclusive of (-1) and inclusive of 2.
Therefore, solution set in set-builder notation will be {x | -1 < x ≤ 2}
Step-by-step explanation:
0.200 in standard form is 2.00 * 10^(-1).
I hate Time4Learning. I took that back in middle school.
Here's how these expressions work together. First, you need to remember WZY is a right angle (90 degrees). Now, keep that in mind when we add both equation.
3c + 2c + 2 - 7 = 90
5c - 5 = 90
5c - 5 + 5 = 90 + 5
5c = 95
5c/5 = 95/5
c = 19. Now, put 19 in the place of c and solve.
3(19) + 2 = 57 + 2 =
59 degrees.
The measurement of angle WZX is equal to 59 degrees, B.
