Once​ Kate's kite reaches a height of 50 ft ​(above her​ hands), it rises no higher but drifts due east in a wind blowing 7 ft d
Margaret [11]

Answer:

dz  = 7.136 (answer)

Explanation:

given height  for kate's kite   = 50 ft  (say y)

due to drift it move towards east =  dx = 7 ft  

string maximum length          = 107 ft ( say z)

we have to find change in z  

that is  dz

it will form a right angle triangle for x , y and z  where x is base y is height and z is hypotenuse

so we get according to Pythagoras Theorem

z^2 = x^2+y^2\\...............(i)

by derivative both side  consider y as constant

2zdz = 2xdx\\dz = {xdx }/z

from (i)  equation

x = \sqrt{z^2-y^2}

dz = \sqrt{z^2-y^2}dx/z

now put the value and find dz

dz = (\sqrt{120^2-50^2)}7/107\\  =((\sqrt{14400 -2500} )\times7)/107

after solving these  we get

dz  =\frac{109.08\times7}{107}  

dz  = 7.136 (answer)

Discuss how the pressure cooker is designed to achieve temperatures above 100°C.​
Elza [17]

With rising heat, the steam pressure inside the pot builds up beyond atmospheric pressure, allowing the temperatures to rise well above boiling point. This design enables to save time, energy, and resources. The temperature inside a pressure cooker can well go beyond 110° C, which reduces the time needed to cook food.
