Um, I think it is probably because he is not always online... Also, they probably don't put the little symobol when they are online. He could also just be inactive on the side of all this, sometimes creators of major sites like this work on other projects that they take more time in. It could also just do with another job. They might just be working on something ofmore interest or more pay, daily life problems, major life problems, family? I don't know, just a thought I guess.

Welll.....did you graph both of the functions?   f(x)=g(x)    would be the x values where the graphs intersect....

Graph g(x) on the same picture and all of your q's will be answered......you are given x and g(x) which is 'y'

So graph the following points for g(x)      -2,-3       0,2    2,0   4,2    6,1     and see what you get.......you can do it .....don't be lazy....

The mean is 176     SD is given as 11.4

How many of 120 are 165# or more

176 - 165 = 11       11/11.4 = 965 standard deviations LESS than the mean....so - .1965 SD from the mean

Using NEGATIVE z-score table

   -.965 is approx .1673     in other words, 16.73 will weigh LESS than 165   ....the remainder    100% - 16.73% = 83.27% will weigh MORE

83.27% x 120 = 99.9 ~~ 100 players will weigh more than 165

You are welcome....this stuff will be very important to you later in your financial life (REALLY!)....learn it well!  ~EP

Y = mx+ b.  Is equation of a line.   M is slope....then sub in the point given to find b

First one slope is -4

Second one slope is -1/(1/5)=-5

Third one slope is -1/(-1/7)=7

With a little less explanation and dimensional analysis:

55 min / 75 pieces   ×  825 pieces = ? Mins

Press the  '2nd' button upper left corner....the sin button will then be asin

Break 1000 into its prime factorization: 2^3*5^2, so 4*4=16 factors. (add one to each power, then multiply) 

Graph the functions on the same coordinate plane.

f(x)=x2−4x+5

g(x)=x+1

What are the solutions to the equation f(x)=g(x)?

\(\color{blue}P_1(1\ ;\ 2)\\\color{blue} P_2(4\ ;\ 5)\)

It is 44. Read this explanation: https://math.stackexchange.com/questions/606794/how-many-times-are-the-hands-of-a-clock-at-90-degrees

LCM of 3, 4, 5, and 6 =10*2*3=60. Then, add 2 for the remainder to get 60+2=62.

You can also use modular arithmetic. 

\(10^{12} = \text{ 1 quadrillion}\)

consider the equation

\((x-2)(x-3)=0\\ x = 2, 3\\ \text{Would you then say }2=3?\)

1.(f+g)(x) = This is fairly simple, all you do is add the two problems.

x² + 7x + 12 + x² + 8x + 16

2x²+15x+28

2.(f-g)(x) = Same thing here, just subtract the two equations.

x² + 7x + 12 - x² + 8x + 16

-x-4

3.(f•g)(x) = 

x⁴+15x³+84x²+208x+192

4.(f/g)(x) = 

x+3/x+4

This is all combining like terms and simplifing. I highly recommend you use www.mathway.com to help you.

Hope this helps! Have a great day!!!

90 =1 | 2 | 3 | 5 | 6 | 9 | 10 | 15 | 18 | 30 | 45 | 90 (12 divisors)

9  = 1, 3, 9 (3 divisors)

9 would be the greatest

Answer:

Y=2x+5

Use the formula: y=mx+c

m=slope

c=Y=intercept

Here is the graph to prove it. :) Hope this helps. Have a great day.

Yes that is exactly what it means

The first answer "The formula for a triangle is base x height"  is wrong 

The formula for the area of a triangle is one-half x base x height 

.

I love red, blue, yellow and green; he prefers black, white, orange and purple. [ No commas before "and"]

NO!! Look at the correct answers on the bottom. CPhill made a mistake in the first one. The LAST term is 2 NOT 12.
