Which pair of vectors is orthogonal?
u = ⟨–3, 2⟩ and v = ⟨–2, 1⟩
u = ⟨1, 5⟩ and v = ⟨–5, 1⟩
u = ⟨2, 1⟩ and v = ⟨–4, 3⟩
u = ⟨2, 3⟩ and v = ⟨3, 1⟩
Answer:
B: u = (1,5) and v = (-5,1)
Step-by-step explanation:
edge 2021
The pair of vectors which are orthogonal to each other will be u = ⟨1, 5⟩ and v = ⟨–5, 1⟩. Then the correct option is B.
What is a vector?The quantity which has magnitude, direction and follows the law of vector addition is called a vector.
For the orthogonal vector, the dot product of two vectors will be zero.
Check first option, we have
u·v = ⟨–3, 2⟩·⟨–2, 1⟩
u·v = 6 + 2 = 8 (incorrect)
Check second option, we have
u·v = ⟨1, 5⟩·⟨–5, 1⟩
u·v = –5 + 5 = 0 (correct)
Check third option, we have
u·v = ⟨2, 1⟩·⟨–4, 3⟩
u·v = –8 + 3 = –5 (incorrect)
Check fourth option, we have
u·v = ⟨2, 3⟩·⟨3, 1⟩
u·v = 6 + 3 = 9 (incorrect)
Then the correct option is B.

Two printers working together can complete a job in 6 hours. Working alone, one
printer takes three times as long as the other printer. How many hours would each
printer need to complete the job alone?
Answer:
Press A takes 10 hours to do a certain job. So Press A does (1/10)th of the job in an hour.
Press A and Press B, together do (1/2.5) or (4/10)th of the job in an hour.
So Press B does (4/10)-(1/10) = (3/10)th of the job in an hour. So Press B can do the job in (10/3) hours or 3 hour and 20 mins.
Check: A does (1/10)th and B does (3/10)th part of the job in an hour. A and B together will take (1/10)+(3/10) = 4/10th of the job in an hour. So they will complete the job in 10/4 = 2.5 hours. Correct.
Answer: Press B can do the job in 3 hour and 20 mins.

A retail store makes k% profit on the selling price. What is the least integer value of k that will enable the store to make a profit of at least 30% of the cost of the item?
Answer:
k = 23% profit on sale price is needed to ensure 30% profit on cost price
Step-by-step explanation:
Let sale price be = s , Profit = k% of s
Let cost price be = 100 , Profit = 30% of c
Cost price (c) + profit (p) = Sale price (s)
c + 0.3c = s
1.3c = s
Profit as a percentage of sale = (Profit / Sale) x 100
= (0.3c / 1.3c) x 100
= 23%

Write an equation for the graph, where y depends on x.
Answer:
y = -3x + 6
Step-by-step explanation:
Equation of straight line is given by,
y = mx + b
m = slope of the line
b = y-intercept
From the graph attached,
m = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
= [tex]\frac{-6}{2}[/tex]
= -3
y intercept 'b' = 6
Therefore, equation of the line will be,
y = -3x + 6

A 6 ounce serving of grapefruit juice contains 171 grams of water. How many grams of water are in 20 ounces of grapefruit juice?
Please help me with this question. I have 2 minutes left to answer it.
Answer:
570 grams of water
Step-by-step explanation:
171 divided by 6 = 28.5
28.5 grams are in 1 ounce
so Multiply 28.5 by 20 to get the new amout which is 570
The amount of water present in 20 ounces of grapefruit juice will be 570 grams.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
A 6-ounce serving of grapefruit juice contains 171 grams of water.
The ratio of the amount of grapefruit and water present will remain constant.
Let 'x' be the amount of water present. Then the equation is given as,
x / 20 = 171 / 6
x = 20 · 171 / 6
x = 570 grams
The amount of water present in 20 ounces of grapefruit juice will be 570 grams.

You spend $63 on books and movies. You pay $12 per book and $15 per movie. You buy 3 more books than movies. How many of each item do you buy?
Answer:12B - 12M = 36
12B + 15M = 63
Subtract one from the other:
12B + 15M = 63
-(12B - 12M = 36
-------------------------
0 + 27M = 27
27M = 27
M = 1
B - M = 3 (from the original equations)
B - 1 = 3
