Answer:
Step-by-step explanation:
Let the exponential function be,
Here, C = cost of the car
t = Duration or period in years
From the given table,
Two points representing cost of the car and time are (10000, 0) and (8520, 1),
For (10000, 0),
a = 10000
For (8520, 1)
8520 = 
b = 0.8520
Therefore, exponential equation will be,
Answer:
y+4=-6(x-7)
Step-by-step explanation:
Point slope form is giving by the equation
y - y = m (x - x)
M being the slope and y and x being points
All you have to do is plug in your slope and point:
(y + 4) = -6 (x - 7)
It means that it does not equal to that certain amount, which is why they put a line across it
Answer 16 cubic cm (cm^3)
Volume of a cube is L x W x H
Since the cube has equal sides of 4 cm
4 x 4 x 4 = 64 total volume of cube
Now we take 25% of the cubes total volume to find the portion filled with sand
25% x 64 = 16 cubic cm
