In a salad with vegetables containing 50 calories dressing is added at 100 calories per ounce.
the total number of calories can be represented by the equation f(x) = 100x + 50.
a. can someone add negative ounces of dressing? what does that mean for the x-values?
b. can someone add zero ounces of dressing? what does that mean for the x-values?
c. can someone have partial ounces of dressing? what does that mean for the x-values?
d. is the function discrete or continuous?

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

i believe the answer is 323 ft

step-by-step explanation:

combine all like terms then its just a 2 step equation
