Answer:
the answer is (c)
Step-by-step explanation:
-(-1)-13= 1-13=-12
<span>Function
1:
Number of Weeks (x) Amount Remaining (dollars) (y)
1 30
2 24
3 18
4
12
You find the rate of weekley rate of change by calculating the difference of the amont remaing between two weeks:
24 - 30 = - 6
18 - 24 = - 6
12 - 18 = - 6
As you see the rate of change is constant: - 6 dollars per week.
The equation shows the relationship between the amount of money, y,
remaining in Ricky's account and the number of weeks, x:
Function 2: y =
–7x + 30 Which statement states and explains which function shows a
greater rate of change?
The rate of change is the slope of the linear function, and this is the coefficient of the independent variable, x. Then the rate of change is - 7 dollar per week. Now you know that the two rates are constant and that the second function shows a steeper decreasing.

Answer:
Step-by-step explanation:
It's first impportant to know what a error interval is:
When we use error intervals we are looking at a number that has been rounded. An error interval tells us the range of numbers that we could have had before the number was rounded. The number has been rounded to 4.8 to one decimal place.
The rotation of 90 degrees counterclockwise maps (x,y) to (-y,x).
(8,2)->(-2,8)
Choice C.
Answer:
1. )
2.) The angle between v and u is 147.52°.
Step-by-step explanation:
Given:
To Find:
1.
2.
Solution:
is scalar product given as,
Here only i.i = j.j =1 and i.j = j.i = 0
∴
Now, Substituting the above values we get
As it is negative mean is in Second Quadrant Because Cosine is negative in Second Quadrant.
1. )
2.) The angle between v and u is 147.52°.
