(50 points and brainliest. )the size of a certain cell is 2.5 × 10^–9 m. another cell is 1.5 × ^times larger. how large is the larger cell in scientific notation?

The answer is 3.75× m.

Step-by-step explanation:

let x denotes the size of certain cell which is equal to 2.5×m.

let y denotes  the size of another cell  which is equal to 1.5x .

y=1.5(2.5×m)

y=1.5×2.5×m

y=3.75×m

Then the size of larger sell is 3.75×m.

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
