The altitude at which we boil an egg affects how long it takes for the egg to achieve perfect hardness.

it takes 198 seconds to boil a perfect egg at the lowest place possible, the edge of the dead sea, which has an

altitude of -418 meters.

the highest place possible is the summit of mount everest which has an altitude of 8848 meters. it takes 209

seconds to boil a perfect egg there.

t(a) models the time (in seconds) it takes to boil a perfect egg at an altitude of a meters.

which number type is more appropriate for the domain of t?

The domain is where is an integer.

Step-by-step explanation:

We see from the data given that the  domain of T(a) takes both positive and negative integer values ( 8848 meters and  -418 meters); T(a) never gets decimal values (and in real life thy won't be of much use because we are not looking for that much accuracy).

So the appropriate number type for the domain of T(a) would be integers. And if you are interested, the domain is .

The first person was correct in the domain, however was incorrect with the integers and is actually the real numbers.

Step-by-step explanation:

Answer is Real Numbers and has the domain of −418 ≤ a ≤ 8848

hope this helps!

a) justify

step-by-step explanation:

justifying is just part of everyday life. justify kind of means proof so i think the answer is a) justify.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
