It takes a snail 10 seconds to move 1 cm how long will it take the sound with 2.5 cm

25 seconds

Step-by-step explanation:

25 seconds

Step-by-step explanation:

If a snail moves 1 cm per second then

x centimeters = 10seconds times x

this is because you multiply the time per cm to the total cm so that you know how long it will take

2.5 x 10 = 25

it will take the sound 25 seconds

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

a, b, c, d are correct.

step-by-step explanation:

we have g(x) = 3 and are required to find which option is a translation of g(x).

now, 'translation' is a transformation which means to shift the function in any direction and the general form of translation is g(x) + k, where k is any real number.

so, according to the options we see that all are correct as they satisfy the general form of translation.

also, it can be seen from the graph below that the function g(x) = 3 is shifted from its position in all the four options.
