Answer:
x<1
Step-by-step explanation:
The open circle means it is not including one meaning it cannot be greater than or equal to, nor can it be less than or equal to.
Since the line is going to the left, this means less think of l for left and less
so leaving us with x<1 / x is less than one
i hope this helps u pls give a brainliest and a thx ;)
Answer:
You know that if f(x) = 1/(x²+1) then F(x)=arctan(x).
What is arctan(x) function? It is inverse function of tan(x) in tge range (-π/2, π/2).
So if tan(x) = y then x = arctan(y)
therefore arctan(-1) = -π/4 because tan(-π/4)=-1 and arctan(1)=π/4 because tan(π/4) = 1.
In conclusion:
integral (dx/(x²+1)) from -1 to 1 =
= F(1) - F(-1) = arctan(1) - arctan(-1) =
=π/4-(-π/4)=π/4+π/4 = π/2.
answer B is correct
Answer:3 I think not sure
Step-by-step explanation:
The single transformation that can be used to map T₁ onto T₂ is Rotate T₁ 180° about the origin.
<h3>What transformation would map T₁ onto T₂?</h3>
When a shape is rotated 180° about the origin, it means that the points go from (x, y) to (-x, -y).
The points on T₁ if rotated 180° about the origin would go from:
(-2, -2) to (2, 2)
(5, -6) to (-5, 6)
(5,0) to (-5, 0)
These are the points of T₂ so the way to map T₁ on T₂ is to use a 180° about the origin.

Answer:
4x=20+4(10); x=15
Step-by-step explanation:
20+4(10)=4x
This is where x is the number of stickers per sheet.
This is the equation because she has 20 stickers.
To find the original number of stickers, we have to add back the amount given.
She has 4 sheets and gave 10 stickers from each sheet. This means she gave away 4*10 stickers.
Now, we can solve the equation:
20+40=4x
60=4x
x=15
