410.3ft^3. is correct





volume of the sphere with 3ft radius :
\frac{4  \times  \pi \times 3 \times 3 \times 3}{3}  = 113




volume of the sphere with 5ft radius:
\frac{4 \times \pi \times 5 \times 5 \times 5}{3}  = \frac{1570}{3}   = 523.3



difference
523.3 - 113 = 410.3

What is the equation of the line that passes through the point (3,4) and has an undefined slope?
rosijanka [135]

Answer:

The equation of the line that passes through the point (3,4) and has an undefined slope is x = 3

Step-by-step explanation:

  • The slope of the horizontal line is zero
  • The equation of the horizontal line passes through the point (a, b) is y = b
  • All the points on the horizontal line have the same y-coordinates

  • The slope of the vertical line is undefined
  • The equation of the vertical line passes through the point (a, b) is x = a
  • All the points on the vertical line have the same x-coordinates

Let us solve the question

∵ The line has an undefined slope

∴ The line is a vertical line

∵ The equation of the vertical line is x = a, where a is the x-coordinate

   of any point on the line

∵ The line passes through the point (3, 4)

∴ a = 3

∴ The equation of the line is x = 3

The equation of the line that passes through the point (3,4) and has an undefined slope is x = 3

I have a square graph, but I would like to make the graph larger.
fenix001 [56]

FORMULA:

  • Area of ⬜ = (side)²

ANSWER:

We are given new side of square i.e, 2s + 3.

So, Area = (2s + 3)²

  • (2s)² + (3)² + 2 × 2s × 3
  • 4s² + 9 + 12s

Hence, The area of the new graph is a perfect square trinomial: __4__s² + __12__s +__9__.

What are the x- and y-intercepts of the line? 2x – 3y = –12<br> Show work
yuradex [85]

Answer:

You can use the intercepts to graph the line. The graph of 2x + 3y = 12 crosses the x-axis at (6, 0), so its x-intercept is 6. The graph of 2x + 3y = 12 crosses the y-axis at (0, 4), so its y-intercept is 4.
