Hope this can help.
I think x-2 is factor of f(x) but x+4 is not.
KE = 0 (because velocity is 0)
PE = mgh = 2kg*9.8m/s^2*40m= 784 joule
<u>Explanation:</u>
KE stands for kinetic energy. In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.
Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. Since in this case, the building is still and therefore it does not have any kind of kinetic energy because there is not acceleration.
Answer:
4.F(x) > 0 over the intervals (-0.7, 0.76) and (0.76, ∞).
Step-by-step explanation:
we conclude that the point on this line that is apparent from the given equation is (-6, 6)
<h3>
Which point is on the line, only by looking at the equation?</h3>
Remember that a general linear equation in slope-intercept form is:
y = a*x + b
Where a is the slope.
Here we have the linear equation:
y - 6= (-23)*(x + 6)
Now, for a linear equation with a slope a and a point (h, k), the point slope form of the linear equation is:
(y - k) = a*(x - h)
Now we can compare that general form with our equation, we will get:
(y - k) = a*(x - h)
(y - 6) = (-23)*(x + 6)
Then we have: k = 6 and h = -6.
Thus, we conclude that the point on this line that is apparent from the given equation is (-6, 6).
