What is the domain of this function?

Step-by-step explanation:

We have been given a function . We are asked to find the domain of our given function.

We know that domain of a function is all values of x for which our function is defined.

Upon looking at our given function, we can see that our given function is a cube root function. We know that a cube root function is defined for all value of x as it is possible for three negatives to equal a negative.

Therefore, the domain of our given function is all real value of x that is and option A is the correct choice.

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
