Answer:
A) 3
Step-by-step explanation:
The notation f(x)=[x] represents the greatest integer function, with the integer being less than or equal to x.
Since we have to find the nearest integer smaller than the given number, we can say that greatest integer function always rounds down its input to the nearest integer.
We have to find the value of [3.6]. So we have to round down 3.6 to its nearest integer, which will be 3.
Therefore, the option A gives the correct answer.
Answer:
(4x -3yi) (4x+3yi)
Step-by-step explanation:
We have a^2 + b^2
Over the complex number, this is equal to
(a-bi) (a+bi)
(4x -3yi) (4x+3yi)
Answer:
-4
Step-by-step explanation:
-1 + -3 = -4
43290-39000=4290
4290÷39000=0.11
0.11x100= 11% increase
white : milk : dark
w : m : d
The ratio of white to not white is 3:4
w : (m+d) = 3:4
The ratio of not dark to dark is 17:4.
(w+m) : d = 17:4
---------
We treat the colons as fraction bars and cross multiply.
4w = 3(m+d) = 3m + 3d
4w + 4m = 17 d
Subtracting,
4m = 17d - (3m+3d) = 14d - 3m
7m = 14 d
m/d = 14/7
m:d = 2:1
Since w:(m+d)=3:4 let's make m+d a multiple of 4.
m:d = 8:4
w : (m+d) = 3:4 = 9:12
w:m:d = 9:8:4
Answer: 9:8:4
Check:
white to non white 9 to 8+4=12 = 3:4, good
non dark to dark (9+8):4=17:4, good
