Mathematics
1 answer:
Olenka [21]2 years ago
7 0

Answer: \displaystyle \frac{2}{3}x^{3/2} + \frac{2}{5}x^{1/2}+C\\\\\\

This is equivalent to \frac{2}{3}\sqrt{x^3} + \frac{2}{5}\sqrt{x}+C\\\\\\

========================================================

Work Shown:

\displaystyle \int\left(\sqrt{x} + \frac{1}{5\sqrt{x}}\right)dx\\\\\\
\displaystyle \int\left(\sqrt{x}\right)dx + \int\left(\frac{1}{5\sqrt{x}}\right)dx\\\\\\
\displaystyle \int\left(x^{1/2}\right)dx + \int\left(\frac{1}{5}x^{-1/2}\right)dx\\\\\\
\displaystyle \int\left(x^{1/2}\right)dx + \frac{1}{5}\int\left(x^{-1/2}\right)dx\\\\\\

\displaystyle \frac{1}{1+1/2}x^{1+1/2} + \frac{1}{5}*\frac{1}{1+(-1/2)}x^{1+(-1/2)}+C\\\\\\
\displaystyle \frac{1}{3/2}x^{3/2} + \frac{1}{5}*\frac{1}{1/2}x^{1/2}+C\\\\\\
\displaystyle \frac{2}{3}x^{3/2} + \frac{1}{5}*2x^{1/2}+C\\\\\\
\displaystyle \frac{2}{3}x^{3/2} + \frac{2}{5}x^{1/2}+C\\\\\\

A cylindrical well has a radius of 8 feet and a height of 13 feet what is the volume of the well use 3.14 for pie round your ans
vitfil [10]
To find the volume of a cylinder, you use this formula:
V = \pir^{2}h

Plug in your numbers,
V = (3.14 * 8^{2}) * 13

Exponents:
V = (3.14 * 64) * 13

Parentheses:
V = 200.96 * 13

Multiply:
V = 2612.48ft^{2}

If a toy rocket is launched vertically upward from the ground level with an initial velocity of 128 feet per second, then its he
natta225 [31]

Answer:

The maximum height of the rocket is 256 feet

Step-by-step explanation:

The vertex form of the quadratic function f(x) = ax² + bx + c is

f(x) = a(x - h)² + k, where

  • (h, k) is the vertex point
  • h = \frac{-b}{2a} and k = f(h)
  • (h, k) is a minimum point if a > 0 and a maximum point if a < 0

Let us use these rules to solve the question

∵ h(t) = -16t² + 128t

→ Compare it by the form of the quadratic function above

∴ a = -16 and b = 128

∵ a < 0

∴ The vertex (h, k) is a maximum point

∴ The maximum height of the rocket is the value of k

→ Use the rule of h above to find it

∵ h = \frac{-128}{2(-16)} = \frac{-128}{-32}

∴ h = 4

→ Substitute x in the equation by the value of h to find k

∵ k = h(h)

∴ k = -16(4)² + 128(4)

∴ k = -256 + 512

∴ K = 256

∴ The maximum height of the rocket is 256 feet
