In a geometric series, the sum of the first 4 terms is ten times the sum of the first 2 terms. If r>1, find the common ratio. - Find the domain and range of f(x)= square root of x-2 then +3?
*By*:-Iggy Rocko

f(x) = √(x - 2) + 3

domain is [2, ∞)

range is [3, ∞)

f(x) = sqrt(x - 2) + 3

The domain of sqrt(t) is t >/= 0 (greater than or equal to 0) - How do you find the length from the vertex of a regular tetrahedron to the center point of its oppos
*By*:-Pope

Consider the equilateral base of the tetrahedron.

If the side of the tetrahedron is 1, then the distance from any vertex to the centre of the triangle is √ - if there are 10 numbers and 9 of them are favorable and I choose 3 what is the probability that at l
*By*:-jerry

Three out of 10 can be chosen in C(10,3) = 120 ways

P(2 favorable, 1 non-favorable) = C(9,2) * C(1,1) / C(10,3) = 36/120

I Don't Keep Secrets From My Fans So - Express as a sum of logarithms. ln 4x?
*By*:-Jenn

ln(4x) = ln4 + lnx

...one of those questio - X+y+2÷2=x+y÷4=2x+y+1=3?
*By*:-victoria

(x + y + 2) ÷ 2 = (x + y ÷ 4) = 2, x + y + 1 = 3

Solution:

x = 2, y = 0

If you meant (x+y+2)/2 = (x+y)/4 = 2x+y+1 = 3,

the parentheses were REQ - Solving a side of a parallelogram?

- 2x+3y=13 with 2x+5y=7?
*By*:-angel mae

2x+3y=13

2x+5y=7

--------------

-1(2x+3y)=-13

2x+5y=7

---------------------

-2x-3y=-13

2x+5y=7

---------------

2y=-6

y=-6/2=-3

2x+5(-3)=7 - Logarithms help please?

If m=log3 and n=log7, express log63 in terms of m and n - prove that the differnce of the squares of two consecutive even numbers is always divisible by 4?
*By*:-marsden6362

Let 2x and 2x - 2 be consecutive even integers (or you can let 2x + 2 be the other even integer).

(2x)^2 - (2x - 2)^2

= (2x + (2x - 2))(2x - (2x - 2)) - Logarithms help please?

*By*:-angel mae

2x + 3y = 13

2x + 5y = 7

y = -3

x = 11

2x+3y =13 ---(1)

2x+5y=7 ----(2)

subtract (2) from (1)

-2y =6

y=-3

2x+3y =13 ---(1)

2x+ - Find f'(2) by using the list definition of the derivative at a point? Will reward Best Answer!?
*By*:-cidyah

f(x) = sqrt(3x) + x

I know you'd do the chain/power rule, I'm just wondering how you'd do it using lim(h-->oo) (f(a+h)-f(a)) / h
