Use newton’s law of cooling, t2 = t0 + (t1 - t0) e-kt, where t0 = temperature of the surrounding area, t1 = initial coffee temperature, k = a constant that depends on the material properties of the object and t = change in time in minutes, to solve the following problem. alex likes his coffee at a temperature of 135f. if he pours a cup of 170f coffee in a 72f room and waits 5 minutes before drinking, will his coffee be too hot or too cold? explain. for alex’s cup, .k=0.34

121 pints. they had 176 and drank 55

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
