Answer:5 hours because -2.5*5=-12.5
Step-by-step explanation:
Answer:
D) The coordinates of 
Step-by-step explanation:
The coordinates of the points are given as A(-4, -2) and B(4,-10).
The ratio is 3 : 1
Le t us assume the point is M (x,y).
⇒ AM : MB = 3 : 1
Now, Using SECTION FORMULA:

Using m1 : m2 = 3 : 1
Here, we get

Hence, the coordinates of 
The surface area of the new figure is 1470 square meters, if the edge length of the smaller cube is half the edge length of the cube below and edge length of bottom cube is 14 m.
Step-by-step explanation:
The given is,
Length of Bottom (larger) cube is 14 meters
Step:1
Surface area of new figure = (Surface area of smaller cube) +
(Surface area of bottom (larger) cube)....(1)
Step:2
Surface area of Bottom(larger) cube is,
..............................................(2)
From given, a = 14 m
Equation (2) becomes,



Surface area of bottom cube, A = 1176 square meters
Step:3
Surface area of smaller (top) cube is,
....................................................(3)
From given, a = 7 m ( ∵ The edge length of the smaller cube is half the edge length of the cube below)
Equation (2) becomes,



Surface area of bottom cube, A = 294 square meters
Step:4
From equation (1),
Surface area of new figure = 1176 + 294
= 1470
Surface area of new figure = 1470 square meters
Result:
The surface area of the new figure is 1470 square meters, if the edge length of the smaller cube is half the edge length of the cube below and edge length of bottom cube is 14 m.
Answer:

Step-by-step explanation:
Given the function 
The average rate of change of the function h(x) over the interval
can be calculated using formula

In your case,

so the average rate of change is
