Newton's law of cooling states that the rate of change in the temperature t(t) of a body is proportional to the difference between the temperature of the medium m(t) and the temperature of the body. that is, * = k[m(t) - tt)], where k is a constant. let k = 0.03 (min) - 1 and the temperature of the medium be constant, m(t) = 292 kelvins. if the body is initially at 362 kelvins, use euler's method with h = 0.1 min to approximate the temperature of the body after (a) 30 minutes and (b) 60 minutes. (a) the temperature of the body after 30 minutes is (round to two decimal places as needed.) kelvins. enter your answer in the answer box and then click check answer.

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.

alright so i think for this one it would to draw it out. this may be hard for me to try and draw, but i will do my best on here:

        r

notice how it forms 2 triangles inside one bigger triangle.

so if we know the angle spr is the same as psr that is saying the measure of angle p is the same as angle s. this means the big triangle psr is either isosceles or equilateral. in both cases, the triangle is perfectly symmetrical when split down the middle, which is in this case rq. because we know it is perfectly symmetrical on both sides, we know that the two triangles inside the bigger one are equal.
