Answer:V(t) = C·(0.5)t
Step-by-step explanation:
V(t) = computer's value at year t = 600
C = initial cost = 2100
t = years

Step-by-step explanation:
Answer: he watched 1/12 of the movie at night.
Step-by-step explanation:
Let x represent how much of the movie that he watched at night.
Tanner watched 1/4 of a movie in the morning, and he watched some at night. This means that she had already watched
x + 1/4 = (4x + 1)/4 of the movie by the end of the day. Therefore, what he has left to watch would be
1 - (4x + 1)/4 = [4 - (4x + 1)]/4
= (3 - 4x)/4
By the end of the day, he still had 2/3 of the movie to watch, it means that
(3 - 4x)/4 = 2/3
Cross multiplying, it becomes
3(3 - 4x) = 4 × 2
9 - 12x = 8
12x = 1
x = 1/12
First trail ... 5 1/3 = 16/3 miles
second trail ... 1 3/4 = 7/4 times as long as the first
We would like to know how many miles Jamal hiked. To answer this question, we have to add miles from the first trail and miles from the second trail.
But first we have to calculate how long was the second trail:
7/4 * 16/3 = 7*4/3 = 28/3 = 9 1/3 miles
Now, we have to add miles from both of the trails:
16/3 + 28/3 = 44/3 = 14 2/3 miles
Result: Jamal hiked 14 2/3 miles.
Answer:
D!
Step-by-step explanation:
a and b - we cant do translations, because the shapes size would be preserved
so its between c and d
c makes it smaller - so even smaller than KLM
d makes KLM larger(into K'L'M'), and since it is the last option, D is correct
