A water wheel has a radius of 21 feet. The wheel is rotating at 15 revolutions per minute. Find the linear speed, in feet per minute, of the water. The linear speed is approximately \( \square \) feet per minute. (Round to the nearest whole number as needed.)

What is the magnitude of a vector with a horizontal component of 5 and a vertical component of \( 12 ? \)

What is the direction of a vector with a horizontal component of 2 and a vertical component of -4 ?

Where is there a discontinuity / are there discontinuities (holes or asymptotes) in the rational function \( f(x)=\frac{x^{2}+3 x+2}{x^{2}-4} ? \) \( x= \) 0 \( x= \) 2 \( x= \) -2 \( x=2 \) -2 \( x=0 \) \( 2,-2 \) \( x \)

Determine the implied domain of the following function. Express your answer in interval notation. \[ f(x)=\sqrt{x}-9 \] Answer

Select your answer What is the direction of a vector with a horizontal component of -2 and a vertical component of -4 ? \( -63^{\circ} \) \( -117^{\circ} \) 0.
