The temperature at a point (x, y) is T(x, y), measured in degrees Celsius. A bug crawls so that its position after t seconds is given by x = 2 + t , y = 3 + 1 2 t, where x and y are measured in centimeters. The temperature function satisfies Tx(2, 4) = 3 and Ty(2, 4) = 5. How fast is the temperature rising on the bug's path after 2 seconds? (Round your answer to two decimal places.)

At  t = 2

Step-by-step explanation:

Using the chain rule we get that

From the information we know that

and using one variable calculus we know that

therefore at  t = 2

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.

the correct answers i think are b. and d.

give me brainliest if it is correct!
