<h3>Given</h3>
a circle with diameter 8 yd
<h3>Find</h3>
the circumference in feet and yards
<h3>Solution</h3>
The circumference of a circle is given by ...
C = πd
where C is the circumference and d is the diameter. For your circle, the circumference is
... C = π(8 yd) = 8π yd ≈ 25.13 yd
There are 3 feet in a yard, so 3 times as many feet.
... C = 24π ft ≈ 75.40 ft
Side BC is congruent to side DC. (That's what the hash marks mean.) Angle C is congruent with itself, and the right angles at B and D are all congruent.
Thus, you want to choose triangle names that show BC congruent to DC. The appropriate selection is the second one ...
∆ADC ≅ ∆EBC
g(x) - f(x) = x^2 - 9 - (2 - x^1/2)
= x^2 + x^1/2 - 11
negative x gives no real value for this function because x^1/2 is not defined for negative x
the domain is x >= 0 or in interval notation [0, ∞)
Answer:
Line of reflection will be y = -2
Step-by-step explanation:
From the picture attached,
Triangle ABC has been reflected over an unknown line so that the triangle ABC will overlap triangle A'B'C'.
To find the line of reflection,
Coordinates of point C → (7, 0)
Coordinates of point C' → (7, -4)
Line of reflection = line passing through midpoint of the line joining C and C'
Midpoint of the line joining points C and C' = 
= 
= (7, -2)
Therefore, line of reflection is y = -2.
