We can determine the correct graph by finding its roots
x² - 4x - 12 = 0
x² - 6x + 2x - 12 = 0
x(x-6) +2(x-6) = 0
(x+2)(x-6) = 0
This means the roots of the function are x=-2, and x=6 and the graph will cross x axis at these two points. From the given graphs, the graph B seems to cross these points.
So the answer to this question is option B
Radius = r = 1 foot
Angular velocity = w = 1 revolutions in 4 seconds
So,
w = 0.25 revolutions per second
Since,
1 revolution = 2π radians
We can write the above equation as:
w = 0.25 x 2π radians per second = 0.5π radians per second
Linear Velocity = v = r w
Using the values, we can write:
v = 1 x 0.5π
= 0.5 π
= π/2 feet per second
Therefore, the correct answer is option B
You multiply five by 3.75 and you get 18.75 ft. to get yards you divide by three and you get 6.25 yards
First order all the numbers least to greatest.<span>
$28, $28, $30, $31, $35, $36, $41, $43
Because there are two numbers in the middle (no, one middle number).
Add the two together, and divide by 2
31 + 35 = 66
66/2 = 33
</span><span>B.$33 is your answer
hope this helps</span>
