What is the best description of the translation of pre-image ABC to image A'B'C'? A'B'C'

Mathematics

Answer:

the translation is 4 units at right and 2 units up

Step-by-step explanation:

see the attached figure to better understand the problem

looking at the graph

we have

The coordinates of the pre-image ABC are

A(-1,1),B(2,2),C(1,-1)

The coordinates of the image A'B'C' are

A'(3,3),B'(6,4),C'(5,1)

so

A(-1,1) ---->  A'(3,3)

A(-1,1) ----> A'(-1+a,1+b)

-1+a=3 ---> a=3+1=4

1+b=3 ---> b=3-1=2

The rule of the translation is

(x,y) ----> (x+4,y+2)

That means ----> the translation is 4 units at right and 2 units up

An accountant needs to withhold 18% of income for taxes if the income is below $40,000, and 27% of income if the income is $40,0
ser-zykov [4K]

Answer:

=IF(A1<40000,(18%*I18),(27%*A1))

Step-by-step explanation:

The spreadsheet expression to  be used is the "IF" function. The "IF" function is one that returns a value based on the conditions stated thereafter in the spreadsheet formula. Like every spreadsheet function, this also starts with =

In the question given,

The value to be examined is in cell A1. if A1 is less than $40000 is written as A1<40000, is true,  the spreadsheets executes the next function stated as  (18%*I18) otherwise (which in this case can be interpreted as A1 greater than or equal to $40000), compute the next command as shown above;  (27%*A1)

The final parenthesis closes the command.

Hence the expression is IF(A1<40000,(18%*I18),(27%*A1)).

A class of 33 students elected a class treasurer. there were 111votes for candidate a and 15 votes for candidate
Advocard [28]

Since 111 is greater than 33, I will assume that you meant 11 votes for a candidate. Also, assuming that each student can vote only once, the answer would be

11/33 x 100=33.333333...

About 33.333 of the voters voted for candidate a.
