Step-by-step explanation:
log243(81)=4/5
81=243^4/5
Option B
Answer:
x-3
Step-by-step explanation:
(x^2-9)(x^2-9)/x^2*(x+3)+9(x+3)
(x+3)*(x^2+9)/(x+3)*(x^2+9) cross multiply
(x^2+9)*(x+3)/(x^2+9) cross multiply
x+3 final anser
Answer:
21.16
Step-by-step explanation:
Starting from the theory we have the following equation:

Using the data supplied in the exercise, we have subtracting the mean and dividing by the standard deviation:

solving for "c", knowing that fi is a tabulating value:

therefore the value of c is equal to 21.16
The s um is positive because 11/12 is greater than 7/8
Slope = Change in y / Change in x
= 8 - 2 / 3 - 1
= 6 / 2
= 3
