Hello :
<span>the parabola's equation is : f(x) = a(x+3)²-1
</span><span>the coefficient of the squared expression in the parabola's equation is : a
but ; f(4) = 0
0 = a(4+3)²-1
49a-1=0.....a=1/49
f(x) = 1/49(x-3)²-2</span>
I’m not sure about this question
Answer:
3 minutes and 30 seconds
Step-by-step explanation:
7-5 = 2
3/2 = 1.5 gallons that empty per each minute
1.5 times 3 (minutes) = 4.5 gallons emptied
Remaining gallons to empty = 0.5
0.5 gallons to empty will take 30 seconds
I hope this helps :)
The equation of the line is y = 3x + 6
<h3>What are linear equations?</h3>
Linear equations are equations that have constant average rates of change.
Note that the constant average rates of change can also be regarded as the slope or the gradient
<h3>How to determine the
equation of the line?</h3>
The given parameters are
Slope, m = 3
y-intercept, c = 6
A linear equation is represented as
y = slope * x + y-intercept
i.e.
y = mx + c
So, we have
y = 3x + 6
Hence. the linear equation is y = 3x + 6

Answer:
Step-by-step explanation:
The work done is the product of the magnitude of the force applied to the object by the magnitude of the displacement of the object by the cosine of the angle between the force and direction of the displacement. This is:
In this case
|F|=180 pound force
The magnitude of vector AB is:
Finally the work is:
