The following chart shows temperatures of cities on a winter morning. city temperature buffalo −8 grand rapids −3 denver 10 chicago −1 a. all of the following statements are true except b. chicago was colder than grand rapids. c. buffalo had the coldest temperature. d. grand rapids was warmer than buffalo. e. denver had the only temperature above zero.

B.Chicago was colder than Grand Rapids. False

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

Chicago (-1 ) > Grand Rapids(-3)

False, Grand Rapids is 2° colder than Chicago.

Since only one statement is false, the other statements are true.

Feel free to ask for more if needed or if you did not understand something.

b. astronomers

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6
