Answer:
9
Step-by-step explanation:
first 3.2x5/4 and then +5 donee..
The answer is 4!·3!=144
the ! is interesting. it goes like this:
1!= 1
2!=2
3!=6
4!=24
this happens because each ! will multiply the number by the answer to the number before it. it is easier to show you though.
1!=1 because 0!=1, and 1*1=1
2!=2 because 1!=1, and 2*1=2
3!=6 because 2!=2, and 3*2=6
4!=24 because 3!=6, and 4*6=24.
so 4!=[(24)*(6)]=3!
24*6=144
Step-by-step explanation:
the diameter is 2 times the radius.
so,
12.7×2 = 25.4
so, B is right.

Of the four x-coordinates to choose only 1/√(11) belongs can belong to the unit circle.
The other three x-coordinates are greater than 1, then they are out of the unit circle.
The unit circle formula is x^2 +y^2 = 1
Then to find the y-coordinate given the x-coordinate you can solve for y from that formula:
y^2 = 1 - x^2
y = (+/-)√(1-x^2)
Substitute the value of x
y = (+/-)√{1 - [1/√(11)]^2} = (+/-) √{(1 - 1/11} =(+/-) √ {(11 -1)/11 =(+/-)√(10/11) ≈ +/- 0.95
