You alwalys put a variable after the slope and then you add the y-intercept. It's pretty easy. For example, if the slope= 7 and the y-intercept= -3 your answer would be y=7x+-3. Get it?

3. a las ocho menos veinte 4. a las cuatro menos cinco 6. a la una menos cuarto

So, basically, the way I can look at problems like these is to subtract the two accelerations (normal's gravity and centripetal) then multiply them by the mass (F=ma)?

you should start by multiplying both sides by 8 (to even out the g on the right) then expand the right side by multiplying each number inside the parenthesis by the number outside. Finally, get all the g's on one side, add them (or subtract) and divide bo...

Yeah. Intercepts are where the graph crosses the x and/or y axis. Looking at your graph on the calculator and tracing it, it never crosses the x axis, right? So you would only have a spot where it crosses the y axis, and tracing it, that point is (0,3).

A basic rule for right triangles is sine(theta) = opposite/hypotenuse 20 = your opposite side theta is your angle rearrange to fit your problem: hypotenuse = opposite/sin(theta) plug in and solve make sure your calculator is in degrees, not radians too.

what you did wrong was this: tan(theta) = opposite / adjacent An easy trick to remember is SOHCAHTOA (pronounced so-ka-toe-a): sin (S) is opposite(O)/hypotenuse(H) cos (C) is adjacent (A)/hypotenuse(H) tan (T) is opposite (O)/adjacent (A) I'm in college c...

yep! That's what I got!

PE = mass * gravity * height figure out the potential energy equations for both (with h as an unknown variable) then set them equal to each other! I think that would work!

I'm sorry, I tried this and got 2.1 and the computer keeps kicking it out as wrong. Your logic makes sense to me after I thought about it. Is there something I'm doing wrong?

wait never mind. There are only 60 seconds in a minute!

I got 10.02 is that right?

thank you soooooo much for the help

Thankyou Ms. Sue

The way to solve this is to use potential and kinetic energy and the formula R = (v^2/g)sin2(theta). mgh=(1/2)mv^2 v=sqrt(2gh) R=(sqrt(2gh)^2/9.8)sin2(theta) = ((4.95)^2/9.8)sin(2*34) =3.27m

How did you get the 4.16?

ok i put the answers in.. now what

its urgent people!!

i needed a better answer

3,600 remember that however many zeros is in 600 is the same number of zeros that should be in your quotient.

You will need to use the distributive property of multiplication. 5/(2y+6) + 1/(y-2) = 3/(y+3) 5/2(y+3) + 1/(y-2) = 3/(y+3) 2(5)/(y+3) + 2/(y-2) = 2(3)/(y+3) 10/(y+3) + 2/(y-2) = 6/(y+3) 2/(y-2) = -4/(y+3) (y-2)(2)/(y-2) = -4(y-2)/(y+3) 2 = -4(y-2)/(y+3)...

one last question. From same set up. Assuming all of the hypochlorite ion comes from sodium hypochlorite, calculate the grams of NaClO in the titrated bleach sample.

5 mL of undiluted bleach was used. Calculate the mass in grams of undiluted bleach that was in the sample of bleach titrated.

use this to get the mass of the bleach? It is telling me my answer is incorrect.

to get the grams of NaClO in the titrated bleach sample I calculated .000721 x 74.44217 = .0536 which was correct. For the previous question I asked I put in the same answer as you said and it is incorrect.

I want to know that too ^ That always stumps me on the hw!

I believe the answer is d.

The Answer is 144.

I am going to start with the slope-point form. y-y1=m(x-x1) y-8=-2x-(-2) or y-8=-2x +2 now you add 8 to both sides to get slope intercept form y=-2x+10

a. y=4x y=2x+10 b. six classes It costs $24 c. Being a member cost is more effective when you go to more than six classes a month.

I think the answer is a or b am I correct.

missing information

First you have to find the amount of water (in grams) that will react with 2 mol of phenylmagesium bromine. Then you convert the grams into mg. Finally, you divid by 25. Reply if you want the answer.

The poem "The Tide Rises, The Tide Falls" by Henry Wadsworth Longfelllow.

You have to first right the balanced formula MgBr + H2O --> Benzene + Mg(OH)Br This means that 2 mols of water will react with 2 moles of phenylmagnesium bromide

2 mol of water equals 36 gram or 36000 mg so the answer is 1440 drops of water

This is a very different problem.

This deals with the slope not the area

So is there an answer or is it undefined

thats not algebra

(55+60+65+65+x)/5=65 x=80 so on the fifth subject he needs an eighty.

the answer is b. The larger a negative number the smaller it is.

well first you can simplify by (x+4)^2=16/9

The probability is 4.5 people.

Ok here it goes 1. carbon dioxide 2. alveoli 3. oxygen is being delieverd more adequately 4. oxygen

I think the answer is d. What do you think?

First multiply the fractions so the denometor is the same. 1/2=4/8, 1/8, and 2/8. SO you can see that the first three children have 7/8 of the estate meaning that the last one gets 1/8. Make sense?

Sorry Tatyana, I knew the answer was b. I don't know why I typed d.

Well if the burn truly is severe you should get medical help. Things you can do for burns are run cold water over burn, aloe, or prescription drugs that you can buy from your health care provider.

First find limiting reactant (KO2). The answer for the first question is 9 mols of oxygen. For the second question 100/(9*16) * 100% = 69.4%

There is no inverse. Did you forget the x?

Ok now I understand what the meter is. I still don't understand how stressing these syllables would effect the poem. Also whats the the poem’s subject matter? This poem uses to many nonword that I can't pick it out.

This website is not designed to do your homework. Ask each question individually with an what you understand and don't understand.

b is the answer Think about it two white, two blue, two red, and two yellow makes eight. than the night has the third one.

I don't understand what the diction or tone is

The idea is to explain how it was like living where he was living I think
