egoroff_w [7]

Given:

The number of members in an organization since the year 2000 can be represented by the function

m(x)=x^2+42x+5

where,  x represents the number of years after 2000.

To find:

The statement  which best describes the term 5.

Solution:

We have,

m(x)=x^2+42x+5

It is clear that 5 is a constant because it is free from variable x.

At x=0,

m(0)=(0)^2+42(0)+5

m(0)=5

It means, 5 is the initial number of members in the organization.

Therefore, there are 5 members in the organization in year 2000.

im really sorry for asking so many questions its just my only way of getting these assignments done on time plus their due tomor
Paul [167]

Answer: 3.84 m

Step-by-step explanation: The biggest clue here is that the scale factor is 1:12.

1:12=32:x

To find x, multiply 32 by 12. 32x12 is 384. You can't say the answer is 384, however, since the label for the actual water tower says "m" for meters instead of "cm" like for the model. 384 cm is equal to 3.84 m.

Hope this helped! ;)
