Find the measure of b.

Mathematics
1 answer:
Alika [10]2 years ago
5 0

Answer:

b = 55°

Step-by-step explanation:

The angle at the centre is twice the angle on the circle subtended by the same arc, then

a = 0.5 × 110° = 55°

Angles on the circumference subtended by the same arc are congruent, so

b = a = 55°

Which phrase best describes the translation from the graph y = (x + 2)2 to the graph of y = x2 + 3?
Mashutka [201]

1. Consider the transformation that maps the graph of the function y=(x+2)^2 into the graph of the function y=x^2. This transmormation has a rule:

(x,y)→(x+2,y)

that is translation 2 units to the right.

2. Consider the transformation that maps the graph of the function y=x^2 into the graph of the function y=x^2+3. This transformation has a rule:

(x,y)→(x,y+3)

that is translation 3 units up.

Answer: correct choice is C.
