Write the expression as a single logarithm. log_3 40-log_3 10 I'm completely confused with logarithmic equations!! Can someone please please help me understand?

**A big question**

Check your sent messages folder in the webmail. You should still have it saved there.

**Chemistry**

Awesome! Thank you so much! My answer was 6.38 x 10^23 molecules

**Chemistry**

@Steve? Still there, buddy? Can anyone else help me, I'm struggling.

**Chemistry**

Yeah the question states that when the solid sodium reacts violently with water, it produces /heat/, hydrogen gas, and sodium hydroxide. I never learned anything about how to write heat into an equation, could you explain it to me?

**Chemistry**

13. Solid sodium reacts violently with water, producing heat, hydrogen gas, and sodium hydroxide. How many molecules of hydrogen gas are formed when 48.7 g of sodium are added to water? 2Na + 2H2O = 2NaOH + H2 So far I have this much figured out: Mass to moles for Na: 48.7g Na...

So for the first one: Domain: (-?,?) Range: (0,?) Y-intercept: 1 and for the second one: Domain: (?,-?) Range: (?,0) Y-intercept: -1 this is what I understood from your response?

**Algebra**

Graph y=5^x and y=log_5 x on a sheet of paper using the same set of axes. Use the graph to describe the domain and range of each function. Then identify the y-intercept of each function and any asymptotes of each function. So far I have: Y=5^x : D: ?? R: y>0 Y-intercept: 1 ...

**Math**

g(4) is basically just telling you to input 4 for x. So in layman's terms... turning -2x+6 into -2(4)+6. That should be enough for you to get on your own. :) Just solve -2(4)+6 and you'll have your answer.

**Algebra**

Haha yeah it was, I wasn't sure if the spaces would register. Thank you for this!!

**Algebra**

Use synthetic division to find P(-3) for P(X)= x^4 - 2x^3 - 4x + 4 So I know how to do synthetic division and all, but I'm still somehow not coming up with the correct answer! Below is my work so far. Please help me interpret it so that I can get the correct answer. Thank ...

?16i^2+x^2+2x+1 But that's not one of my possible answers?

**Algebra**

Which quadratic equation has roots -1+4i and -1-4i ? A. x^2+2x+2=0 B. 2x^2+x+17=0 C. x^2+2x+17=0 D. 2x^2+x+2=0 I'm having difficulty with this question, but I've settled on C for now. Am I correct?

For the record, it was Weber's Law :)

Would the answer be Weber's Law?

Which phenomenon does the following example illustrate? When you begin your first year of college, the tuition is $12,000. At the beginning of your second year of college the tuition has been raised by $200, but you do not notice. However, upon returning for your third year of...

**Algebra**

What is the vertex form of the equation? y = -x^2+12x-4 My work: -(x^2 + 12x)-4 -(x^2 + 12x + 36)-4 + 36 Y= -(x+36)^2 + 32 Is this correct? I am not sure if I did this right or not? Thank you!

**Algebra**

Yes, sorry about that! I didn't know how to type in the necessary symbols. I was only confused concerning the 3 in the final answer. I wasn't sure if it was meant to be -3 or 3. From my understanding, I was right in thinking it was -3, right? :)

1. How many real solutions does the function shown on the graph have? The graph is following the function: y=(x+2)^2 A. No real solutions B. One real solution** My answer C. Two real solutions D. Cannot be determined 2. What is the solution to 3x^2+3x+5=0? I have the answers ...

I just need to confirm an answer I got when trying this out myself. I'm not too confident so I would appreciate it if someone could tell me if this is correct before I turn it in? 2x^2-16x+32=0 My answer was simply x=4. I got this from using the quadratic formula. Thank you!

**algebra 2**

Find the square root of positive 28, then put the i next to it. For example the square root of -25 would be 5i because 5 is the square root of positive 25. Hope this helped!

**READING**

I do not think it is simile because it does not have the word 'like' in it nor does it compare anything. I think your best bet is an oxymoron because it is kind of contradicting itself. First ask yourself what slander is and why it would be an oxymoron if the media did...

I called my teacher and we agreed that it was participial. Thank you Ms. Sue! :)

**English**

The site said that the preposition was explaining the "which one" question which would give more information on the topic. So in this case, asking the question 'which one?' would be like this: Which idea of alien life? The one "proposed many years ago&...

**English**

Oh okay! So it is a prepositional phrase, right?

**English**

Identify the phrase in parenthesis in the sentence. The idea of alien life, (proposed many years ago), has not yet been proven. prepositional participal gerund infinitive** I thought it might be an appositive, but now I'm not sure. I'm guessing it is D?

Oof this was confusing because of the clashing opinions, but yes A: Being trapped between two worlds is correct!

Somemthing is correct, just took the quick check!!
