Answer:

Step-by-step explanation:

<span> The coordinates of the focus are </span><span><span>(<span>h,k+<span>1/<span>4a</span></span></span>)</span><span>(<span>h,k+<span>1/<span>4a</span></span></span>)
y=1/38*x^2
here h=0,k=0 ,a=1/38
so if we put values to find focus
focus(0,0+1/4*1/38)=(0,9.5)

Answer: 22
Step-by-step explanation:
The area of the picture =l×b = 20×16=320
The length of the frame is 16
If the width is x ( and it's uniform)
672- 320= 352
Area of the frame = 16× x=352
x=352/16
x = 22
Answer:
=7x
Now,
Putting the value of x= 5 then we get,
=7×5
=35
