Use vector operations to draw the resultant vector
Draw 2u – 1/3v.
Answers
Vectors are elements of the vector space, and they can be illustrated by diagrams.
How to draw the vector 2u - 1/3vThe vector expression is given as:
2u - 1/3 v
Split the vector expressions, as follows:
[tex]y_1 = 2u[/tex]
[tex]y_2 = -\frac13v[/tex]
See attachment for the graphs of y1 and y2.
Next, we have:
[tex]y = 2u - \frac13v[/tex]
So, we have:
[tex]y = y_1 + y_2[/tex]
The above expression means that, we add the vectors y1 and y2 to get vector y

Regina currently makes $15 an hour. Her boss decided to give her a 7% raise. Write the expression she would use to determine how much more she will make per hour.
Answers
Answer:
[tex]\frac{7\times15}{100}[/tex]
Step-by-step explanation:
Given the following question:
7% of 15
To find the answer we need to use the formula to calculate percentages in which we multiply the percentage by the whole number and then divide that answer by 100, of course rounding to the nearest cent if needed.
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{7\times15}{100}[/tex]
[tex]7\times15=105[/tex]
[tex]105\div=1.05[/tex]
[tex]=1.05[/tex]
7% of 15 is "1.05" which means Regina receives a $1.05 raise.

You have 12 coins. Some quarters and dimes. You have a total of $2.40, how many of each coin do you have?
Answers
Answer:
8 quarters and 4 dimes
Step-by-step explanation:
4 quarters = 1 dollars
4 quarters = 1 dollars
4 dimes = 40 cents
2.40$
============================================
Work Shown:
d = number of dimes
q = number of quarters
1 dime = 10 cents
d dimes = 10d cents
1 quarter = 25 cents
q quarters = 25q cents
d+q = 12 since we have 12 coins total
q = -d+12 after solving for q
10d+25q = total value in cents
10d+25q = 240
10d+25(-d+12) = 240 ... plug in q = -d+12
10d-25d+300 = 240
-15d+300 = 240
-15d = 240-300
-15d = -60
d = -60/(-15)
d = 4
q = -d+12
q = -4+12
q = 8
Since d = 4 and q = 8, this means we have 4 dimes and 8 quarters
-----------------------------
Check:
4 dimes = 4*10 = 40 cents
8 quarters = 8*25 = 200 cents
(4 dimes) + (8 quarters) = (40 cents) + (200 cents) = 240 cents
240 cents = 240/100 = $2.40
We have 4+8 = 12 coins total

Two adults and one child go to a movie and pay $26. One adult and 3 children pay
$28. How much would it cost for one adult and one child to see the movie?
Answers
Answer:
adults pay $10
children pay $6
Step-by-step explanation:
x = adult
y = child
2x + y = 26
x + 3y = 28
you want to cancel out x or y
multiply -2 with (x + 3y = 28) which is -2x -6y = -56
2x + y = 26
-2x -6y = -56
-5y = -30
y = 6
put y back into an equation
2x + y = 26 is
2x + 6 = 26
x = 10
check the answer
Two adults and one child go to a movie and pay $26
20 + 6 = 26 : checks
One adult and 3 children pay $28
10 + 18 = 28 : checks

% compounded continuously. After 15 years, how much more money would Lillian have in her account than Melanie, to the nearest dollar?
Answers
Answer:
$8727
Step-by-step explanation:
The difference in investment values can be found by computing the value of each investment, then finding the difference. Here, we're concerned with investments compounded quarterly and compounded continuously.
a)Melanie's investment value is computed using the formula ...
FV = P(1 +r/n)^(nt) . . . . where P is the principal, r is the annual rate, t is the number of years
FV = $63,000(1 +0.07125/4)^(4×15) = $63,000(1.0178125^60)
FV = $181,721.94
__
b)Lillian's investment value is computed using the formula ...
FV = Pe^(rt)
FV = $63,000·e^(0.07375×15)
FV = $190,449.05
__
c)The amount more that Lillian has is ...
$190,449.05 -181,721.94 = $8,727.11
Lillian has about $8727 more than Melanie.
