Answer:

The new surface area will be 121\ mm^{2}

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its surface areas is equal to the scale factor squared

In this problem

The scale factor is \frac{1}{4}

so

Multiply the scale factor squared by the original surface area to obtain the new surface area

(\frac{1}{4})^{2}*1,936=121\ mm^{2}

*repost since nobody answered* how would i answer this?
pshichka [43]

Answer:

b is not a function

Step-by-step explanation:

To be a function there must be a one to one correspondence.

Each x must only go to one y

b has an x that goes to two different y's

1 goes to 5 and 13.  That makes it a relation not a function

Determine whether the sequence is arithmetic if so what’s the common difference -9 -33-57-81
QveST [7]

Answer:

Arithmetic.

Common Difference: -24

Step-by-step explanation:

An arithmetic sequence is a sequence with the difference between two consecutive terms constant. The difference is called the common difference. A geometric sequence is a sequence with the ratio between two consecutive terms constant.

For arithmetic, to find the common difference we take any pair of successive numbers, and we subtract the first from the second.

For geometric, to find the common ratio can be found by dividing any term in the sequence by the previous term.
