Solve the logarithmic equation. y=log(4) 0.25 enter your answer in the box. y =

y = -1

Step-by-step explanation:

y=log(4) 0.25

This can be written as indices as;

㏒(a) b = x    ⇒⇒ aˣ = b

∴ ㏒(4) 0.25 = y

0.25 = 25/100 = 1/4 = 4⁻¹

∴

This translates to;

y = -1

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21

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.
