The tangential line at a certain point is just the derivative so.

. At the point (1,6) we plug the x value in and get the slope at the point (y ' = 2)
The tangential line at that point is
y - 6 = 2(x - 1) (this is the answer)
Answer:
Franco has 66 baseball cards.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of baseball cards that Franco has.
y is the number of baseball cards that Juan has.
Franco has 18 fewer baseball cards than Juan.
This means that:

Also:

Together they have 150 baseball cards.
This means that:

Since

Answer:
<u>The area of the hexagon is A. 96√3 cm²</u>
Step-by-step explanation:
Let's recall the formula of the area of an hexagon, this way:
Area = (3√3/2) * s²
Area = (3√3/2) * 8²
Area = (3√3/2) * 64
Area = 192√3/2
Area = 96√3 cm²
<u>The area of the hexagon is A. 96√3 cm²</u>
