5 0

Answer:

at 0  the amount is 5

1 is 7.5

2 is 10

3 is 12.5

the initial value is the y intercept when the value ox x=0

the initial value is 5

the rate of change is the total change of a function of the out put (y) divided by the change of the input (x)

f(x2)-f(x1)/x2-x1

10-7.5/2-1

2.5/1=2.5

or m=y2-y1/x2/x1=10-7.5/2-1=2.5

y=2.5x+5

Given f '(x) = (x + 1)(6 + 3x), find the x-coordinate for the relative minimum on the graph of f(x).
FinnZ [79.3K]

Answer:

x = -1

Step-by-step explanation:

The easiest way is just to find the antiderivative and graph.  The antiderivative is x^{3} + 4.5x^{2} + 9x + C.  Graphing this with any C shows that x=-1 is the relative minimum.

No, its D

Just look at the rounds mentioned and subtract the scores from higher round with lower round.

Look at A: round 2 score - round 1 score = -2?
-3 -1 = -4 change, not -2 change so it is wrong

Look at B: round 3 score - round 1 score =-1?
-2-1 =-3 change, not -1 change so it is wrong

Look at C: round 3 score - round 2 score =-1?
-2 -(-3) = 1 change, not -1 change so it is wrong

Look at D: round 3 score - round 1 score =-3?
-2-1 = -3 change, matches with -3 so it is correct.

100 POINTS! WILL BE MARKED BRAINLIEST!!
QveST [7]

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.
