In april 2011, an online social networking site had approximately 200 million registered
accounts. in august, the number of registered accounts had risen to 3.62 x 108. in scientific
notation, how many more users were there in august than in april?
a 1.62 x 108
b 1.62 x 10
c 1.62 x 10
d 1.62 x 105

is should be y = 5x

step-by-step explanation:

correct me if im wrong

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
