I think the answer is C
ludmilkaskok [199]3 years ago
4 0

Answer:

  C.  red (0,5); green (0,0), (0,-9)

Step-by-step explanation:

The y-axis is found where x=0. So, the (x, y) coordinates of any y-intercept are

  (0, y-value)

Knowing this lets you ignore answer choices A and B.

__

The points where the curves cross the y-axis are conveniently marked with their values (except for y=0) ...

  red: y=5

  green: y=0, y=-9

Filling these numbers into the above form gives ...

  • red: (0, 5)
  • green: (0, 0), (0, -9) . . . . . . matches choice C

How do you do this question?
r-ruslan [8.4K]

Step-by-step explanation:

y = 3 + 8x^(³/₂), 0 ≤ x ≤ 1

dy/dx = 12√x

Arc length is:

s = ∫ ds

s = ∫₀¹ √(1 + (dy/dx)²) dx

s = ∫₀¹ √(1 + (12√x)²) dx

s = ∫₀¹ √(1 + 144x) dx

If u = 1 + 144x, then du = 144 dx.

s = 1/144 ∫ √u du

s = 1/144 (⅔ u^(³/₂))

s = 1/216 u^(³/₂)

Substitute back:

s = 1/216 (1 + 144x)^(³/₂)

Evaluate between x=0 and x=1.

s = [1/216 (1 + 144)^(³/₂)] − [1/216 (1 + 0)^(³/₂)]

s = 1/216 (145)^(³/₂) − 1/216

s = (145√145 − 1) / 216

Solve x − 2y = 3 for x.
wolverine [178]

Answer:

x=2y+3

Step-by-step explanation:

So we have the equation:

x-2y=3

And we want to solve for x. In other words, we want to isolate the x-variable.

So, add 2y to both sides of the equation.

(x-2y)+2y=(3)+2y

On the left, the 2y cancel. Simplify the right:

x=2y+3

And we're done!
