DO NOW: 5/14A & 5/15B Part#2 Check/Fix these & Explain Why For each of the following, check the work and the answer. Write either “it is
correct as is”, or show the correct work and answer. If the answer is wrong, explain why it is wrong in detail.<< a) -42 = 16 MOST of you said this was right The correct answer is -16 You won’t do

well on SATs or Freshman college math/placement test if you make this careless mistake! REMEMBER PEMDAS
TURN THIS IN TODAY: -52 = (-7)2 =
b) If r=0.5 and t=2, er t = 3.29744 You must do the EXPONENT(s)
FIRST (PEMDAS) TURN THIS IN TODAY: If r=2 and t=3, er t =
c) SQRT(-25) = -5 MOST of you didn’t answer this correctly either NEITHER -5 x -5 nor +5 x +5 equals -25 If you remember imaginary numbers, the answers are +/- 5i
TURN THIS IN TODAY: SQRT(-81)= (please don’t email me that can’t do this LOOK at the example
above ! !!!)
d) CubeRoot(-8) = imaginary (no real number) MANY of you did this wrong too. The question is asking WHAT THREE (identical) numbers multiplied together gives you -8 (“cube root”). ITISJUST-2 since -2x-2x -2=-8,sotheansweris-2!!!(aREAL number)
TURN THIS IN TODAY: CubeRoot(-27)=

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

40 minutes

step-by-step explanation:

add the time and multiply by 2

the most boring thing ever written

step-by-step explanation:

i am writing something. yes, i plan to make it the most boring thing ever written. i go to the store. a car is parked. many cars are parked or moving. some are blue. some are tan. they have windows. in the store, there are items for sale. these include such things as soap, detergent, magazines, and lettuce. you can enhance your life with these products. soap can be used for bathing, be it in a bathtub or in a shower. apply the soap to your body and rinse. detergent is used to wash clothes. place your dirty clothes into a washing machine and add some detergent as directed on the box. select the appropriate settings on your washing machine and you should be ready to begin. magazines are stapled reading material made with glossy paper, and they cover a wide variety of topics, ranging from news and politics to business and stock market information. some magazines are concerned with more recreational topics, like sports card collecting or different kinds of hairstyles. lettuce is a vegetable.
