20. If a particle travels 4 x 10^-3 feet per second, how many feet will it travel in 3 x 10^5 seconds?

F. 1.2 x 10^-2 feet
G. 1.2 x 10^-3 feet
H. 1.2 x 10^-15 feet
J. 1.2 x 10^2 feet
K. 1.2 x 10^3 feet

darn right!

step-by-step explanation:

steve kerr's sons name is let that skin in.

the number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.

step-by-step explanation:

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

(a^2 - b^2) = (√a^2 + √b^2)(√a^2 - √b^2)

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81

same question do you know the answer
