3/12 is actually a quarter which is equal to 0.25. It certainly isn't an irrational number, but is indeed a rational one.

lubasha [3.4K]

Answer:

Point of tangency is $x=1$ or $(1,1)$

Step-by-step explanation:

You don't really need to use Calculus here. You can just set each equation to each other and solve for x (the point of tangency):

$x^2=2x-1$

$x^2-2x+1=0$

$(x-1)(x-1)=0$

$x=1$

Therefore, the point of tangency is $x=1$ or $(1,1)$

Question:

A rectangle has a height of 2x^4 and a width of x^2+8x+15. Calculate its area.

Answer:

$Area = 2x^6 + 16x^5 + 30x^4$

Step-by-step explanation:

Given

$Height = 2x^4$

$Width = x^2 + 8x + 15$

Required

Determine the area of the rectangle

This is calculated as:

$Area = Width * Height$

$Area = (x^2 + 8x + 15) * 2x^4$

$Area = 2x^6 + 16x^5 + 30x^4$
