X/10 = 10 / 16
16x = 100
x = 100/16
x = 25/4
answer is F. 25/4
From the problem we have
In △ABC, m∠A=52°, c=11, and m∠B=19°.
Draw the diagram with the help of given information, (see the attached image)
Now using Sine Law in the Triangle ABC, we can write
Now from Triangle ABC , we can write


Now simplify , we get

Parabola has a vertex at: ( 0, 3 )
h = 0, k = 3;
y = a ( x - h )² + k
a = 1
y = ( x - 0 )² + 3
y = x² + 3
Answer:
The parabola with a vertex at ( 0, 3 ) is : y = x² + 3
Just by looking at the answer choices, you can eliminate the last one because it is greater than the original price. And the first one is way too less, so your answer is B
