Answer:
x = - 2
Step-by-step explanation:
Given
y = 4x² + 16x - 18
with a = 4, b = 16 , then the equation of the axis of symmetry is
x = - = - = - 2
Answer:
Step-by-step explanation:
y - 1 = -3(x - 6)
Answer:
210 MPH
Step-by-step explanation:
The formula to find speed from distance and time is Speed= Distance/Time. so in this case 420 miles( distance ) divided by 2 hours ( time ) and you get 210 mph.
The periodicity of function is
<em><u>Solution:</u></em>
Given that we have to find the period of function
<em><u>Given function is:</u></em>
<em><u>Use the below formula:</u></em>
Thus,
Now find the periodicity of cos(x)
We know that,
periodicity of cos(x) =
Therefore,
Thus the periodicity of function is
Answer and Step-by-step explanation:
-3(x + 5) > 12
Divide both sides by -3, then flip the sign.
x + 5 <em><</em> -4
Now subtract 5 from both sides.
x < -9
<u>x < -9 is the answer.</u>
