Answer:
14981yd^2
Step by step:
1) surface area formula: SA=2bs+b^2
s=height
b=square of base
so
SA=2*71*70+71^2
SA=2*71*70+5041
SA=9940+5041
SA=14981
Given:
The number of members in an organization since the year 2000 can be represented by the function

where, x represents the number of years after 2000.
To find:
The statement which best describes the term 5.
Solution:
We have,

It is clear that 5 is a constant because it is free from variable x.
At x=0,


It means, 5 is the initial number of members in the organization.
Therefore, there are 5 members in the organization in year 2000.
I got 4/27
I did 8/9 divided by 6/1
If the flask shown in the diagram can be modeled as a combination of a sphere and a cylinder, then its volume is

Use following formulas to determine volumes of sphere and cylinder:
wher R is sphere's radius, r - radius of cylinder's base and h - height of cylinder.
Then
Answer 1: correct choice is C.
If both the sphere and the cylinder are dilated by a scale factor of 2, then all dimensions of the sphere and the cylinder are dilated by a scale factor of 2. So
R'=2R, r'=2r, h'=2h.
Write the new fask volume:

Then

Answer 2: correct choice is D.
