The x-intercepts of the graph of y=2x^2- 16x + 30 are (3,0) and (5,0). a. What is the a-coordinate of the vertex? How do you know?
b. Use your answer to part (a) above to find the y-coordinate of the vertex. Then write the vertex as a point (, y).

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51

step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
