The size of a certain cell is 2.5 x 10^-9 m. another cell is 1.5 x 10^3 times larger. how large is the larger cell in scientific notation? a.) 4 x 10^-27m b.) 4 x 10^-12m c.) 3.75 x 10^6m d. 3.75 x 10^-6m i honestly have no idea what to do.

1) C. -15x^4y

2) B. -18/m^5n

3) C. 768x^11

4) A. 2.535x10^10

5) D. 3.75x10^-6m

b and c

step-by-step explanation:

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
