Answer:
y= 1/4 (x -8)
Step-by-step explanation:
x -4y= 20
-4y= -x + 20
y= 1/4 × -5
y - y1 = m (x - x1)
y - 0 = 1/4 (x -8)
y= 1/4 (x -8)

<h2>
Step-by-step explanation:</h2>
Solving for
is the same as isolating it. In this problem, we have the following equation:

So we need to do the following steps:
Step 1: Interchange the order of the equation:

Step 2: Divide the whole equation by
:

Step 3: Simplify

Finally, this h is in term of b and is:

Answer:
4.647 to the nearest thousandth.
Step-by-step explanation:
The formula for the length of an arc between x = a and x = b is
a
∫ √( 1 + (f'(x))^2) dx
b
Here f(x) = √x so
we have ∫ (√( 1 + (1/2 x^-1/2))^2 ) between x = 0 and x = 4.
= ∫ ( √( 1 + 1/(4x)) dx between x = 0 and x = 4.
This is not easy to integrate but some software I have gives me the following
length = √17 + 1/8 log(33 + 1/8 √17)
= 4.647.
