Describe how to find the vertex of a parabola if you are given the equation

Mathematics
1 answer:
emmainna [20.7K]3 years ago
3 0

Answer:

The vertex of a parabola is (h,k)

Step-by-step explanation:

The vertex form of a parabola is y=a(x-h)^2+k where a is the stretch/compression factor and (h,k) is the vertex. So to find the vertex, you will need (h,k) which represents the horizontal and vertical shift of the parabola

This formula converts a UK shoe size to a Japanese shoe size. Japanese size = UK size + 19
LuckyWell [14K]

Yuto wears a Japanese size 29.5.

By the problem,

Japanese size = UK size + 19

Or, 29.5 = UK size +19

Or, UK size = 29.5-19 = 10.5

Yuto’s shoe size would be 10.5 in the UK

Can somebody help me with this question plz!
Sati [7]
X=8.5 because angle B and angle D are congruent using alternate interior angles theorem. so you would find the measure of B by adding 50+45 to get 95, then subtract 95 from 180 to get 85 degrees for angle B. Now your equation is 10x=85 so if you divide 85/10 you get x=8.5! hope this helped :)
