Answer:
3 left; 1 down
Step-by-step explanation:
You can determine the translation by identifying corresponding points on the two figures and counting the grid squares between them.
__
Here Q is a translation of P by 3 squares to the left and 1 square down.
Answer:
x = 2/3
Step-by-step explanation:
Let's unpack the equation from our definition of
:
(where
)
Now that we've got things defined in terms of familiar operations, we can simplify and solve for x:
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) =
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 = --------(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 =
eⁿ =
ln(eⁿ) = ln(0.9194)
n = -0.08403
From equation (1),
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
