Sorry for bothering. My teacher hasn't taught me this yet. Where did you get .693147181? What is the ln? Is it the same as the e?

Here is a couple:

1)  4^2 * 4^2 = 4 ^(2+2) = 4^4 = 256     You try #3

4) is   2¹ * 2² *2²    and solved similarly   #2 is also similar    4¹  * 4² 

5)  2n^4 * 5 n^4 = 10 n^6      You try  #6

 e = 2.7182818284590452    (see the 'e' on the calculator?)

So solve this for t (the years the question is asking )

11200 = 5600 e^.059t         First divide both sides by 5600

2 = e^.059t                       Now take the ln of both sides

.693147181= .059t         Now divide both sides by .059 to find t years = 11.78 years ~~ 12 years (rounded)

If x + 2 is a factor,    then   x+2 = 0    x = -2

if you sub in -2 to the parent function it should equal 0 if x +2 is a factor

f(-2)        -2       is not

g(a-6)      put in   'a-6'   for 'x' in the g function

[6-(a-6)] / [6+(a-6)] = (12-a)/a   

For the last one  sub in   x^2-6     for   'x' in the  g function and see what you find.....

Couple of things ya just have to remember

An inscribed angle in a circle intercepts an arc TWICE its size in degrees

   the first inscribed angle is 88 degrees     the arc is therefore 88 x 2 =176 degrees

The second one is similar except you are given the ARC.....what would be the angle if the arc is twice the angle?

I haven't done this type of problem in a few years so I may be wrong but the answer I got was x=-1 and the remainder 8. Sorry if it's wrong, it's been awhile since i've done a problem like this

Technically, that IS the nomenclature or definitions used for the parts of a number in scientific notation:

https://www.shmoop.com/basic-operations/scientific-notation.html

...and from Wikipedia:
In mathematics, a coefficient is a multiplicative factor in some term of a polynomial, a series, or any expression

So people DO understand that the 5.28 portion is known as the coefficient.  

2^2-4*1*(-3) 

We have

2^2 - (4 * 1 * -3)   =

4  - (-12)  =

4 + 12  =

16

For the first part.....I believe  "m"  = 16/3

But....I don't understand the second part of the question, at all....I haven't seen something like this before

Let x be the square meters of material used to make 1 cloak  and y be the  square meters of material used to make 1 dress

We have these equations   :

2x  +  3y   =   9.6        multiply through by  -4   ⇒   -8x  - 12y  = -38.4        (1)    

3x  +  4y   = 13.3        multiply through by  3    ⇒    9x  + 12y  =  39.9        (2)

Add (1)  and (2)    and we get that

x  =  1.5  =  the square meters of material needed to make one cloak

And the number of square meters to make one dress can be found thusly :

2 (1.5) + 3(y)  = 9.6

3  + 3y  =  9.6              subtract 3 from both sides

3y   = 6.6                   divide both sides by  3

y  = 2.2  = the square meters of material needed to make one dress

Number three is wrong. Technically, that is, pedantically speaking there isn’t a coefficient.

A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression.  There is no variable here, so there is no coefficient. 

(Oh, and it’s not a physical constant either. There is no reference to any kind of physical relation.)

P.S. If you need a string of curses, I can provide them for you ... in several languages.

do you know where i can find info on the first question?

Maybe the proctor/teacher likes to play “Simon Says.” Simon didn’t say you were converting from a base other than 10, so you are wrong.

It’s a great way to take smart students down a peg and to elicit a string of curses. 

you're right, good catch, tired

x - 7< 18     add  7 to both sides

x < 25

To graph :    draw a number line with a circle at 25

From this point, draw an arrow back to the left

Correct, Jenny   !!

Checked here : https://matrix.reshish.com/multCalculation.php

nope, it was True

Rom: You missed 125. So, there are 4 such integers: 5, 25, 125, 625. Or: 4 / 1005.

Thanks man

yes....

I suppose,noting that mos of your recent questions are pertaining to scientific notation , that this would be true....

Most of your recent questions have been    of the form    5.28 x 10^-3     (scientific notation questions)....so YES, the negative exponent would move the decimal point ot the LEFT      5.28 x 10^-3    WOULD equal  .00528       TRUE

Sorry for confusing you if I did (the question is unclear/incomplete ....not your fault!)

It's C ?

I assume that you want to convert from scientific notation to standard notation

So....for instance

3.2  x 10^-2     =       .032

So.....we move the exponent to the left

Only standard notation
