Answer:
12-2(n-1).
Step-by-step explanation:
It can be written 12-2n+2=14-2n, so that when n=1, the 1st term is 14-2=12. The 5th term is 14-10=4; the 6th is 14-12=2.
Answer:
Advantages:
- It is easier for people to choose an option rather than to write an essay. The questionnaire reflects what the person is thinking and what the person's point of view is, which as a result makes it easier to analyze and conclude results
- A wide range of questions can be asked within one questionnaire, which makes it an effective way to conduct a survey/test

Answer:
Her mother will donate $24
Step-by-step explanation:
In order to find this, first find the unit rate. To do so, divide the amount by the number of miles it takes to get that amount.
$0.40/0.25 miles = $1.60 per mile
Now we multiply that by the total number of miles.
$1.60 per mile * 15 miles = $24

Step-by-step explanation:
Answer:
Angle between the two vectors is 20.7718°.
Step-by-step explanation:
The given two vectors are x = (1,2,3,4) and y = (4,2,4,5)
Now the dot product between two vector is defined as
x.y = ║x║║y║cosθ
Now, x.y( dot product of x and y) = 1×4 + 2×2 + 3×4 + 4×5 = 40
║x║= 
= 
║y║= 
'
Thus, we get
40 = ×
×Cos θ
Thus, Cos θ = 
Cos θ = 0.935
θ = 
θ = 20.7718°
