Answer:
C
Step-by-step explanation:
The graph is of the "greatest integer" (floor) function shifted up by 3 units. Hence the appropriate choice is C.
__
The greatest integer less than or equal to x for 0 ≤ x < 1 is 0, so the horizontal line segment at f(x)=3 indicates 3 has been added to the function.
_____
<em>Additional comment</em>
The brackets used for floor and ceiling functions only have horizontal bits below or above (respectively) the enclosed argument. The usual square brackets [ ] need explanation as to their meaning if they are intended to indicate one or the other of these functions.
Answer:
see below
Step-by-step explanation:
There is actually a cool trick to this. When you see a and 2a, in this case 6 and 12, then the small triangle is a 60-30-90 triangle. The remaining side is
.
This value rounds down to 10, and yep, you guessed it, another 30-60-90.
This time, x =
.
This is a very difficult problem and requires knowledge of the special triangles. Hope this helps!
Answer:
$1.32
Explanation:
For 25 grams it costs $0.44 and for 100 grams it costs $1.76 so Samadhi payed $1.32 more than Karega.
X-2y=14
X=14+2y
X+3y=9
X=9-3y
14+2y=9-3y. (+3y)
14+5y=9. (-14)
5y=-5
Y=-1
X-(2x-1)=14
X--2=14
X+2=14
X=12
X+(3x-1)=9
X+-3=9
X-3=9
X=12
Therefore X is equal to 12
