Answer:
Step-by-step explanation:
The domain includes all x values, and here, it is [-2, 4].
Answer:
m∠3 = 24°
Step-by-step explanation:
By the theorem,
"Intercepted arc measures the double of the inscribed angle formed by two chords meeting at one point of the circle."
In the given picture,
∠3 is the inscribed angle subtended by the arc ED and is the intercepted arc.
Therefore, m∠3 = 
m∠3 = 
= 24°
Measure of angle 3 is 24 degrees.
Answer:
x=12
Step-by-step explanation:
32/2x = x/9; because the triangles are similar
32 = 2x^2/9
288 = 2x^2
144 = x^2
x = 12 or x = -12, but the latter is nonsensical.
Answer:
Yes
Step-by-step explanation:
The definition of a rational number is a number that can be represented as a fraction. Since 56/7 is a fraction it must be a rational number. An irrational number is a number that cannot be represented as a fraction because it never ends and repeats without a pattern forever. An example of this is pi because pi can never exactly be represented as a fraction.
