thanks

you do 2.7 X 4.23=Y 10^2 X 10^2=10^4 and you get... Y X 10^4

Welcome

There is also a way to do this in a graphic calculator... first put your calculator into degree and scientific mode Next type each problem in like this: (2.7,2) x (4.23,2) which will give you your answer. (*when u put the comma in, the calculator will show an E instead)

thank you so much! I think I just overcomplicated the problem. thank you for making it much easier!

Which of the given numbers are composite? 0,1,15,19,23,31,49,55,59,87,91,97,103, 105

ANSWER: +.1 M M J

Can some one please help me with these questions I can not find the correct info. 3. Traumatic events do not always result in a diagnosable psychological disorder. What factors determine how a person may be affected by one such event? 4. What are the four stages in meeting the psychological needs of disaster victims? 7. List and briefly describe four psychological treatments for physical disorders.

oops wrong area Anyway the reaction is sodium 4-chlorophenolate + chloroacetate ion --> 4-chlorophenoxy-acetic acid

Okay, so I was thinking since this is an SN2 reaction, the leaving group would be Cl- or Br- when using either alkyl halide. The rate would increase because Br- is a weaker base than Cl- (because SN favors weak bases as a leaving group). Can someone correct me if I'm wrong?

y=X^2 has an x-intercept of (0,0) and a y-intercept of (0,0), so yes

I need help. I don't understand this one at all. My problem is the same, just the numbers are a little different. Potassium permanganate reacts with sulfuric acid as per the equation shown below. Indicate the excess reactant after the reaction of 7.90 g KMnO4 and 10.32 g H2SO4.

1 cm (cubed) = 10 mL 17 cm cubed x 10 mL = 170 mL

Thank You

The y intercept is in the equation (0,1) You have to factor it to find the x intercepts: f(x)=(x-2)(x-1) (0,2) and (0,1)

Well, I understand what you mean by the solution, but I am getting a really long decimal as the answer, so that's not an excat value. Please, can you help me some more?

THANK YOU!!!!!

sorry g(x) should read 5x^2-9

Thanks a lot.I can build on that. I'm not quite as Clueless :)

I'm not sure if this may help, but it's worth a try. 4\1/2 /3\ (imagine an "x") If you meant something like (4x-2) = angle 4 and angle 2 = (5x-3) : You can simply set up the equation as: 4x - 2 = 5x - 3 Since you know this is related to geometry, I can tell you the two angles are equal to each other because they are vertical angles. These are angles opposite of each other when two lines cross and share the same vertex. If this method sufficed, "x" will equal to 1.

Sorry I meant Na2CrO4 and Na2Cr2O7 and basically i need to know if they react exactly the same with different elements

thanks so much

thank you. I thought that but was not sure

6x+7y-5=0 +5 +5 6x+7y=5 -6x -6x 7y=5-6x /7 /7 y=(5-6x)/7

1.05x1.80x21.6=40.824 40.8 cubic meters of earth removed

Do you mean one fourth OF two thirds? If so, multiply them: 1 2 2 1 - x - = - = - 4 3 12 6

use a^2 + b^2 = c^2 a=1000 b=5280

width = x length = 3x perimeter = 3x+3x+x+x > or = 48 8x > or = 48 divide by 8 x > or = 6

I can't believe all the student over the years with the same questions from UOP. I am a student there as well. I am having a hard time with this assignment as well. I believe the assignment was created after 9/11 and has never been updated because there is nothing new on this topic. I am so stuck right now.

Well, I do not have an answer, but lets say it IS a head on collision. How would this problem get solved?

Thank You So Much! ^0^

My son has this question tonight for homework. I think the answer is the 18th person would get both coupons. I made a diagram. 5xs then a F for the free fruit coupon, i went up to 4 groups then a F. then i went back and counted to the ninth person and put a j for juice above it. The 18th person had both a j and a f. xxxxxFxxxxxFxxxxxxFxxxxxF, then count 9, and put a j for juice above it. The 18th person has both coupons.

What is the level of significance?

1. In a study on caffeine and stress, college students indicated how many cups of coffee they drink per day and their current stress level on a scale of 1 to 10. The table shows the survey results. Using a web-calculator, obtain the appropriate correlation coefficients.

IQ | 1.0000 Psy | 0.5923 1.0000 Stat | 0.7367 0.7105 1.0000 a. corr(iq, psych) = 0.5923; coeff. of det. = 0.3508. b. corr(iq, stat) = 0.7367; coeff. of det. = 0.5576. c. corr(stat, psych) = 0.7105; coeff. of det. = 0.5048.

Number of cups of coffee Stress level 3 5 2 3 4 3 6 9 5 4 1 2 7 10 3 5 my professor says it The correlation coefficient is 0.8519. I don't understand how he arrived at this could someone please show me step by step that he would get this answer... Thank you

Question 1 -B Question 2- A Question 3- C Are these correct

Thank you!

I needed help learning how to find the value.

Not sure that is why I asked :)

#10- There is no contract - Merlin never made an offer

c) Nearly all of the OH- comes from the first ionization. e) The approximations are usually valid because the first ionization constant is usually much larger than the second ionization constant. b) The concentration of OH- and the conjugate acid of the weak base (the anion of the salt) are approximately equal.

Westly estimated 5.82-4.21to be about 2. Is this an overestimate or an underestimate? Explain.

They're different in meaning because in 1, the lady looked up AT the man. So she physically had to look up AT him. In 2, the lady looked up TO the man. As in, I look up TO my brother. He is a great student. So she idolizes him is kind of the meaning.

Please Steve, how did you find -3 and 1/3?

Answer would be.... NaCH3COO + CO2 + H2O

275, 000. $650

thanks for the explanation. is there any way you can review my other question?

Makes sense now. Thank you!

The infinity symbol is on top of the summation notation and the n=2 is on the bottom of it. then the (-2)^(n-1) is right next to it. Please help!

Okay, thanks! Would the sum of it be 1/3? I’m not really for sure on if it can even have a sum of 1/3 since the first four terms i got were 1,-2,-4,-6

You are a blessing! I was iffy about the whole thing. Thank you:)

the summation notation has an infinity symbol at the top and “n=2” on the bottom. Then, (-2)^(n-1) right next to it.

So the answer is just 8? or is it 8 and 10? I need two even integers. This is confusing:(

It’s A

2u^2 (u+5)+5 (u+5)

Homies answers are 100% correct as of 0ct 2021

Y’all are slow, it’s C jesus
