I added them together since they say " Altogether "
The dish illustrates operations on a parabola.
The depth of the parabolish dish is 160 feet.
The bowl is said to be a parabola.
So, we have:

Where:


From the question, the diameter is 160 feet.
So, the radius (r) is:

So, the coordinate of the depth of the parabola would be:


Substitute these values in 
So, we have:


Divide both sides by 160

Rewrite as:

Hence, the depth of the parabolish dish is 160 feet.

Answer:
-5.55-4.2c
Step-by-step explanation:
-5.55-8.55c+4.35c
-8.55c and 4.35c are like terms so you have to combine them.
-8.55c+4.35c=-4.2c
-5.55 is NOT a like term so it is on its own.
final answer -> -5.55-4.2c
*** don't forget -5.55 is negitive ***
hope this helped negative:)
The answer is c I took the test
It would be 1.34x10 to the power of 6
