a solid object is dropped into a pond with a temperature of 20°c. the function f(t)=ce^(-my)+20 represents the situation, where t is times in minutes, c is a constant in k= 0.0399.

after four minutes the object has a temperature of 35°c what was the initial temperature of the object round your answer to the nearest tenth, and do not include units

The initial temperature of the object was 37.6

Step-by-step explanation:

we have

where

f(t) represent the temperature of the object in degree Celsius

t is the time in minutes

Find the value of the constant C

we have the ordered pair (4,35)

substitute in the equation and solve for C

Find the initial value of the object

we know that

The initial temperature is the value of f(t) when the value of t is equal to zero

so

For t=0

therefore

The initial temperature of the object was 37.6 (I not include units)

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
