Stefan's law of radiation states that the radiation energy of a body is proportional to the fourth power of the absolute temperature t of a body. the rate of change of this energy in a surrounding medium of absolute temperature m is modeled as follows: 1. dt k(m4 - t4)where k > 0 is a constant let k = 0.05, m-3 t(0) = 4 estimate t (1) using euler's method with a step size of 0.25 and a step size of 0.1. explain the results.

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1

95.03 is the answer. hope this !
