Answer:
the answer is 6.966×10^-3
The volume of the pyramid is changed by a factor of 125
<u>Solution:</u>
Given that, each side of a pyramid is multiplied by a factor of 5.
We have to find how will the volume of the pyramid changes?
Now, we know that, volume of a pyramid 
Now, each dimension is multiplied by factor of 5.
Then, volume of new pyramid 
Volume of new pyramid = 125 
volume of old pyramid.
Hence, the volume of the pyramid is changed by a factor of 125.
I'll assume you're asking for the initial price
Let's use x to represent it
The initial price plus 40 percent of that is $294
Let's write that out mathematically
x + (40/100)x = 294
x + 0.4x = 294
1.4x = 294
x = 210
The initial price is $210
variable is in power so it exponential.
the constant and coefficient both are positive so it is exponential Growth.
The first step is to find the distance from the given point to each of the two foci as follows:
Distance D1:
(D1)^2 = (9-1)^2 + (0-6)^2 = 100
D1 = 10
Distance D2:
(D2)^2 = (11-1)^2 + (6-6)^2 = 100
D2 = 10
The constant sum is the summation of the two distances as follows:
constant sum = D1 + D2 = 10 + 10 = 20
The correct choice is:
a) 20
