Plug in "8i + 15j + k" for "f", and "2i – 5j + 9k" for "e"
3(8i + 15j + k) - 2(2i – 5j + 9k)
Distribute 3 to (8i + 15j + k) & - 2 to (2i – 5j + 9k)
3(8i + 15j + k) = 24i + 45j + 3k
-2(2i - 5j + 9k) = -4i + 10j - 18k
-------------------------------------------------------------------------------------------------------------------
Simplify. Combine like terms
24i - 4i + 45j + 10j + 3k - 18k
(24i - 4i) + (45j + 10j) + (3k - 18k)
20i + 55j - 15k is your answer, or (C)

Step-by-step explanation:
Area of circle= Πr²
Πr² = 132² m
r²=132²/Π m
=5546.23m
r =√5546.23
=74.473 m
Answer:
19 r2
Step-by-step explanation:
okay so if you have 19.5 and there are 4 people per chair lift. You have to find half of 4 because .5 equals one half in this situation.
4 divided by 2 equals 2 so your remainder is 2
Answer:
Its C
Step-by-step explanation:
Yasim is Albert who ran the race at a time that was 15.7 seconds shorter, So, Yasim is the student who improved the most by decreasing the time needed to run the race.
<h2>Given that,</h2>
Coach Burns charted the change in his runners' 5K times from the first race of the year to the second race of the year.
<h3>We have to
find,</h3>
Which student improved the most by decreasing the time needed to run the race?
<h3>
According to the
question,</h3>
Coach Burns charted the change in his runners' 5K times from the first race of the year to the second race of the year.
In the given option Yasim has the lowest value of the time which is -37.5 seconds.
Yasim was the most improved student because Yasim ran the second race in a time that was 37.4 seconds shorter than the first race.
Following Yasim is Albert who ran the race at a time that was 15.7 seconds shorter.
At the third place in improvement is Cody who actually was worse off than the first race along with the 4th place Hannah.
Hence, Yasim students improved the most by decreasing the time needed to run the race.
