Vector

.

. So the sum is

.
For the second, the magnitude is the square root of the sum of the squares of the components. This is equal to

.
If you divide 100 by 25 you will get 4. Then you multiply 4 and 2, which
will get you 8. So, it will take her 8 weeks to pay her parents.
Answer:
Hence he will be 4 large containers and 4 small containers
Step-by-step explanation:
Given data
Let the number of small containers be x
and the number of large containers be y
x+y= 8---------1
also
2x+4y= 24-----2
the system of equation to solve the problem is
x+y= 8
2x+4y= 24
from 1
x=8-y
put this in 2
2(8-y)+4y= 24
16-2y+4y= 24
2y= 24-16
2y= 8
y= 8/2
y= 4
put y= 4 in 1
x+4=8
x= 8-4
x= 4
Hence he will be 4 large containers and 4 small containers
Answer:
Step-by-step explanation:
The inequality equation can be determined by using the concept of arithmetic progression;
a(n) = a₁ + (n-1)d
where;
a(n) = 1000
a = 200
d = 50
The inequality will be:
1000 = 200 + ( n - 1) 50
1000 = 200 + 50n - 50
1000 = 150 + 50 n
1000 - 150 = 50 n
850 = 50 n
n = 850/50
n = 17 months
So, if Ms. Thomas is planning to have more than $1000 in her account, she will need to save for 17 moths before she can buy the phone.
