Answer:

a.) 12 + 5√2 - 2√6

b.) 24

Step-by-step explanation:

a) √25 + √50 - √24 + √49

  • √25 + √50 - √24 + √49

Calculate the square root .

  • 5 + √50 - √24 + 7

Simplify the radical expression.

  • 5 + 5√2 - 2√6 + 7

Combine like terms.

  • 5 + 7 + 5√2 - 2√6
  • 12 + 5√2 - 2√6

b.) √2 ( 2√8 - 3√32 + 4√50 )

  • √2 ( 2√8 - 3√32 + 4√50 )

Simplify the radical expression.

  • √2 ( 4√2 - 3 × 2²√2 + 20√2)

Evaluate the power.

  • √2 ( 4√2 - 3 × 4√2 + 20√2)

Calculate the products.

  • √2 ( 4√2 -12√2 + 20√2)

Combine like terms.

  • √2 × (4 - 12 + 20 )√2
  • √2 × 12 √ 2

Multiply.

  • 2 × 12
  • 24

A water wheel has a radius of 9 feet. The wheel is rotating at 5 revolutions per minute. Find the linear​ speed, in feet per​ mi
guajiro [1.7K]

Answer:

90\pi\text{ ft/s}\approx282.74\text{ ft/s}

Step-by-step explanation:

Refer to physics equation v=\omega r, where \omega is angular velocity.

Angular velocity's SI unit is rad/s. Convert rev/min to rad/s:

\displaystyle 5\text{ rev/min}=5\cdot \frac{1}{60}\cdot 2\pi\approx 0.524\text{ rad/s}

Now substitute \displaystyle\omega=\frac{1\pi}{6} and r=9 into v=\omega r:

\displaystyle v=\frac{1\pi}{6}\cdot 9=\frac{3}{2}\pi\text{ ft/s}=\boxed{90\pi\text{ ft/s}}
