a small object with an initial temperature of 135 degrees fahrenheit is dropped into a tube with a temp afire of 60 degrees fahrenheit. the function f(t)=ce^(-kt)+60 represents the situation, where t is the time in minutes c is a constant and k is a constant. after 6 minutes the object has a temperature of 85 degrees. what is the approximate value of k?

answer: idk

step-by-step explanation:

14

step-by-step explanation:

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
