X^-2=4. You got it correct:)
Answer:

Step-by-step explanation:
You are given the relation 
This means that

The input values of this relation are
, so the domain of this relation is 
The output values of this relation are
, so the range of this relation is 
Hey! The surface area is 294. Have a great day. :-)
Well, to calculate the area, we would simply do length times width and we would get our area.
Area = Length * Width
Area = 12cm * 4cm
Area = 48cm squared.
So, in conclusion, the area is 48 cm squared.
If a secant<span> and a </span><span>tangent of a circle </span><span>are drawn from a point outside the circle, then the product of the lengths of the secant and its external segment equals the square of the length of the tangent segment.
</span><span>
y</span>² = 7(15+7)
<span>y</span>² = 7*22
<span>y</span>² = 154
<span>y = </span>√154
<span>y = 12.4 </span>← to the nearest tenth<span>
</span><span>
