Celsius thermometer readings were −1°, 33°, 28°, −5°, and 0° throughout the week. which set shows the temperatures decreasing? a. {−1°, −5°, 0°, 28°, 33°} b. {33°, 28°, 0°, −1°, −5°} c. {0°, −1°, −5°, 28°, 33°} d. {28°, 33°, −5°, −1°, 0°}

Decreaseing means starting with the biggest number and ending with positive
bigger=positive
smaller=negative
the bigger the positive, the bigger it is
the bigger the neative number, the smaller it is

so we look at the temps given
-1,33,28,-5,0
gropu all the positives
33,28
33 is bigger
start with 33 then 28
so far we havv 33,28
the only set that starst with that is set B
answer is set B

Set B, shows the decrease in temperature.

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
