If y = 3, then you substitute 3 into wherever it says y.
So the original:
y² - 5y + 2
becomes:
3² - 5×3 + 2.
which is:
9 - 15 + 2.
9 - 15 = -6
-6 + 2 = -4.
-4 is the answer.
Step-by-step explanation:
Firstly convert the diameter into cm
t480812.5cm³hus 3.5×100=350cm
Volume=
=480812.5cm³
The area of the circle with a diameter of 3 inches is 7.07 in2
Answer:
B
Step-by-step explanation:
The greatest integer function is defined as the greatest integer less than or equal to x.
for example,
[x] = greatest integer less than or equal to x.
[3.5] = 3
[-3.6] = -4 (because -4 is less than -3.6)
[-5]=-5
[12]=12
[ π ] = 3
[ π /2 ] = [ 1.57 ] = 1
[ π ] /2 = 3/2 = 1.5
[[ π ] /2 ] = [ 1.5 ] = 1
etc.
It is also called the floor function.
