Answer:
360
Step-by-step explanation:
v = length x width x height
v = 15 x 8 x 3
v = 360
AB * BE = CB * BD were given
so CB/BE = AB/BD ------------> property of proportion
<ABC = < DBE ------------> vertical angles
triangle ABC ~ triangle DBE ------------> SAS <span>Similarity propery</span>
Answer:
the third option
Step-by-step explanation:
Our equation is

Equation of a vertical parabola is

where (h,k) is the center
The focus is
(h+p, k)
Equation of directrix is
x= h-p,
Here the center is (10,0)
Next, we factor out 4 in the original equation

So we have

So our p=9,
So our focus is
(10+9,0) or (19,0)
The third option is the answer
1. L1= 7 L2=7 W1= 3 W2=3 2. L1= 5 L2=5 W2=5 W2=5 3. L1= 6 L2=6 W1=4 W2=4
