Find the distance between the points (5,-1) and (5,-7)

Mathematics
1 answer:
Alina [70]2 years ago
5 0

Answer:

The distance between the points is 6sqrt(5) units

Step-by-step explanation:

Use the distance formula:

d=sqrt([x2-x1]^2+[y2-y1)^2) where d is the distance between (x1,y1) and (x2,y2)

d=sqrt([-1-5]^2-[-7-5]^2)

d=sqrt([-6]^2-[-12]^2)

d=sqrt(36+144)

d=sqrt(180)

d=6sqrt(5) (since distance is positive)

alexandr1967 [171]

Answer:

n = 120i + 310j + 60k

p = 29i + 18j + 21 k

Total cost = $10,320

Step-by-step explanation:

Let n and p represent the vectors for number of products and prices respectively.

Also, the coordinates i,j and k represent cashews, walnut and Brazil nut respectively.

The vector form of the total number of bags ordered and the cost are;

n = 120i + 310j + 60k

p = 29i + 18j + 21 k

We can obtain the total cost by obtaining the dot product of the two vectors.

Total cost = n.p = (120i + 310j + 60k).(29i + 18j + 21 k)

C = 120×29 + 310×18 + 60×21

C = $10,320

A credit card states that your payment will be a minimum of $15 plus 1% of your unpaid balance. Your unpaid balance is $2,365.Wh
Pachacha [2.7K]
Alright, to get 1% of his unpaid balance, we can make 1% = 0.01 by moving the decimal place 2 places over. Multiplying 0.01 by 2365 gets 1% of your unpaid balance=23.65. Since we have to add 15 as a base value, we have 
15+23.65=38.65
