PLEASE HELP!
Leona [35]

Answer:

The initial temperature of the object was 37.6

Step-by-step explanation:

we have

f(t)=Ce^{(-kt)} +20

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

35=Ce^{(-0.0399*4)} +20\\Ce^{(-0.0399*4)}=15\\C=15/e^{(-0.0399*4)}\\C=17.6

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

f(0)=(17.6)e^{(-k*0)} +20\\f(0)=17.6 +20\\f(0)=37.6

therefore

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

Which of the fractions is in lowest terms and is equivalent to -1.25
hjlf

Answer:

  The lowest terms equivalent to - 1.25  =  - \frac{5}{4}

Step-by-step explanation:

- 1.25 = - 1\frac{25}{100}

         = - ( 1 × 100 +25) ÷ 100

         =  -( \frac{125}{100} ) × (\frac{5}{5}

        =  - \frac{25}{20}

        =  - (\frac{25}{20}) × (\frac{5}{5}

        =  - \frac{5}{4}

2(n - 1) + 4n = 2(3n - 1)
Sloan [31]
2(n - 1) + 4n = 2(3n - 1)
2n - 2 + 4n = 6n -2
6n - 2 = 6n - 2 (equal)
6n - 6n = 2 - 2
0 = 0

whatever value you put into the place of n, you'll get 0 = 0
