The size of a certain cell is 2.5*10^-9m. another cell is 1.5*10^3 times larger. how large is the larger cell in scientific notation?

2.5 × 10⁻⁹ × 1.5 × 10³ = 3.75 × 10⁻⁶  

As you can see, you multiply the numbers in front of 10s, and add the exponents.

i think

  3.75 * 10^-6.

Step-by-step explanation:

Multiplying:

1.5 * 10^3 * 2.5 * 10^-9

= (2.5*1.5)  *  10^(3 + (-9)

= 3.75 * 10^-6.

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
