Answer:
c. 52 rad/s
Step-by-step explanation:
Final question does not correspond with available option. The real question is: <em>What is the angular speed in radians per second?</em>
At first we assume that spin balance rotates at constant rate and convert given angular speed, measured in revolutions per minute, into radians per second:
Which corresponds to option C.
Answer:
x-intercept: (-3,0)
y-intercept: (0,-3)
Step-by-step explanation:
Looking at the equation, we can see that it is already in standard form, or in a format. Whenever a line is put into standard form, the x-intercepts are represented by
and the y-intercepts are represented by
. So, let's calculate them by doing the following:
1) Find the x-intercept by using the formula. Substitute the number on the right side of the equation for
and the coefficient for the x term for
. So, in this case,
and
:
Therefore, the x-intercept is (-3,0).
2) Next, find the y-intercept by using the formula and substituting the right values.
is still the number on the right side of the equation and
is the coefficient of the y term. So,
and
.
Therefore, (0, -3) is the y-intercept.
