Answer:
w=105rpm
Step-by-step explanation:
The link between The lineal movement and and angular movement is V=w*r
w has units in rad/s, r is the radio of the rotating/moving element .
15 miles per hour= 15*63360 in/h= 950400 in/h= 15840 in/min
with the above relation we can use the link we were talking in the first paragraph.
15840 in/min=w*24in.
w=660 rad/min
w= 660 /(2 pi) rpm= 105rpm
2x^2-5x+k has a double root when k= 3.125 or 3 and 1/8.
Just plug in -3 for x and solve
y= -10

Answer:
{x | x > -4}
Step-by-step explanation:
The direction of the < or > sign only changes when numbers are multiplied or divided by negatives.
Because to simplify 9x > -36 you only need to divide by 9, the sign stays the same and the numbers are simply divided:
x > -4
So the solutuon set would be:
<h3>{x | x > -4}</h3>
