Use the power rule
d(x^n)/dx = n·x^(n-1)
to form the derivative.
f'(x) = 4·2x -4
f'(x) = 8x - 4
Now, substitute "a" for "x" to find f'(a):
f'(a) = 8a - 4
Answer:
49.62
Step-by-step explanation:
You can start by dividing the shape into 2 separate rectangles to make calculating the area easier.
9.3 x 2.4 = 22.32
10.5 x 2.6 = 27.3
Then, add the areas of the two separate rectangles to find the total area of the shape.
22.32 + 27.3 = 49.62. Hope that helped
Answer:
belongs to the line 
. Please see attachment below to know the graph of the line.
Step-by-step explanation:
From Analytical Geometry we know that a line is represented by this formula:
Where:
- Independent variable, dimensionless.
- Dependent variable, dimensionless.
- Slope, dimensionless.
- y-Intercept, dimensionless.
If we know that 
, 
and 
, then we clear slope and solve the resulting expression:
Then, we conclude that point belongs to the line , whose graph is presented below.
