we are given
we can check each options
option-A:
-1,1
we can plug x=-1 and x=1 and check whethet f(x)=0
At x=-1:
At x=1:
so, this is TRUE
option-B:
0,1
we can plug x=0 and x=1 and check whethet f(x)=0
At x=0:
At x=1:
so, this is FALSE
option-C:
-2,-1
we can plug x=-2 and x=-1 and check whethet f(x)=0
At x=-2:
At x=-1:
so, this is FALSE
option-D:
-1,0
we can plug x=-1 and x=0 and check whethet f(x)=0
At x=-1:
At x=0:
so, this is FALSE
Answer:
Prob.3
Denote r: radius of circle O
Formula for calculating AOB sector:
Area = pi*r^2*angle/360
Area = pi*r^2*45/360 = 18 pi
=> r^2 = 18*360/45 = 144
=> r = 12
For prob.4, give it a try, follow the formula I gave. Good luck !
(answer : r = 6)
Answer:
So first we have 10x = 0. We divide by 10 on both sides, so then we get x = 0. We still have 0 because 0/10 = 0.
So that means that the answer is
<h2><u>
Write 10 in the first box 10 in the second</u></h2><h2><u>
x=0</u></h2>
Answer:
cheese
Step-by-step explanation:
It must be an odd number because 3^7 is also shown as:
3x3x3x3x3x3x3
Which equals:2,187
2,187 is an odd number because the last number is a 7 which is odd.
