The Law and Order detectives enter a house at 11:30 am and found a man on the floor murdered. They take his body temperature fin
taurus [48]

Answer:

Time of murder = 10:39 am

Step-by-step explanation:

Let the equation of exponential function representing the final temperature of the body after time 't' is,

f(t) = a(e)^{nt}

Here, a = Initial temperature

n = Constant for the change in temperature

t = Duration

At 11:30 am temperature of the body was 91.8°F.

91.8 = 98.6(e)^{nt} --------(1)

Time to reach the body to the morgue = 12:30 pm

Duration to reach = 12:30 p.m. - 11:30 a.m.

                              = 1 hour

Therefore, equation will be,

84.4 = 91.8(e)^{n\times 1}

eⁿ = \frac{84.4}{91.8}

ln(eⁿ) = ln(0.9194)

n = -0.08403

From equation (1),

91.8 = 98.6(e)^{-0.08403t}

(e)^{0.08403t}=\frac{98.6}{91.8}

ln[(e)^{0.08403t}]=ln[\frac{98.6}{91.8}]

0.08403t = 0.07146

t = 0.85 hours

t ≈ 51 minutes

Therefore, murder was done 51 minutes before the detectives arrival.

Time of murder = 11:30 - 00:51

                          = 10:90 - 00:51

                          = 10:39 am

ASAP HELP FOR NUMBER 12, Thank you so much!!! :)
qaws [65]
12a)
5x + 45 + 3x - 25 = 180
8x + 20 = 180
8x = 160
  x = 20

12b)
2x - 5 = 2(20) - 5 = 40 - 5 = 35
3x - 25 = 3(20) - 25 = 60 - 25 = 35

y = 180 - (35+35)
y = 180 - 70
y = 110

Can some please help with this I will give brainliest.​
3241004551 [841]

Answer:

x^{-28}*7^{-56}

Step-by-step explanation:

Firstly, you need to know that raising a fraction to a power raises both the top and the bottom to that power.

Second, a negative power on the top and bottom flips the fraction

Last, raising a power to a power multiplies the powers

So, \frac{7^{-8^{7}}}{x^{4^7}}=\frac{7^{-56}}{x^{28}}=\frac{1}{x^{28}*7^{56}}=x^{-28}*7^{-56}
