We know that the line is tangent at the point (2,8)
The derivative of the function at x=2 is

So, the tangent line passes through the point (2,8) and has slope 2. The equation is

This line crosses the x axis where y=0:

Answer:
26 cm
Step-by-step explanation:
The area of a trapezium is
A = 1/2 (b1+b2)*h where b1 and b2 are the lengths of the bases
910 = 1/2 ( 21+49) h
910 = 1/2 (70)h
910 = 35h
Divide by 35
910/35 = 35h/35
26 = h
Good night,
<span>Irrational numbers
are those that can't be expressed as a fraction:
12.89 can be expressed as: </span>


<span>The above numbers
can be expressed as a fraction, then the logical answer is: </span>

But we will check the answer:

As you can see we can't express that number as a fraction, so that is te correct answer.
It would be x=3.50 because 8 divided by 4 is 2 and 14 divided by 4 is 3.5
