Step-by-step explanation:
f(-1) =4.5

Note that A and D are ludicrous choices, so you can throw them away outright. (Any divergent series cannot have a sum, and any convergent series must have a sum.)
The sum is certainly convergent because it can be written as a geometric sum with common ratio between terms that is less than 1 in absolute value.


We can then find the exact value of the sum:




So the answer is B.
Answer:
Constant of Proportionality is 0.6 or $0.60 per oz
Step-by-step explanation:
Divide $2.40 (cost) by 4 ounces (the number of the item) > 2.40 ÷ 4. Also known as Y/X.
Do you mean a cube has a surface area?
If so we identify by how many faces a cube has which is 6. That would mean to find the surface area we add each squares area to get 24. So we divide 24 and 6 to get the area of each face.
24 / 6 = 4 m^2
We know that a square has equal side lengths thus finding that A = a^2. We find the square root of 4 to get the length of each square.
sqrt 4 = 2 m
Answer:
Rise is a vertical line from 0 to 4
Run is a horizontal line from 0 to 4
Slope of a line is called the gradient.
Additional information:
Gradient =rise/run
= 4/4
= 1
Y=mx +c
Y=1x +4
Y= x+4
But the slope show a negative correlation, so gradient will be negative & it's y = - x + 4.
BTW the rise and run could also be from 4 on the y-axis and down to the 4 on the x-axis.
So, there is two possible triangles you could make.
As a result, the rise is a straight line going up or down ( vertical ) and the run is a straight line going across from left to right (horizontal).
