Answer:
54.8
Step-by-step explanation:
Pythagorean theorem is a^2+b^2=c^2.
Plug the given values in to get 61^2+b^2=82^2
61^2 is 3,721 and 82^2 is 6,724.
6,724-3,721 is 3,003.
The square root of 3,003, rounded to a reasonable value, is 54.8.
The length of AC is 54.8.
The result of the log function 
is 60
According to the law of logarithm if 
then 
Given the following expressions
This can be expressed as
Substitute the value of m and n into the expression to have:
This shows that the result of the log function is 60

n - 7 = 9
Step-by-step explanation:
so basically just make up a random variable and place it for the "twice a number" then u sovle it as a 2 step equation
We have two points so we can find the gradient using y1-y2/x1-x2
gradient = 21-27/2-8
= 1
we know the form for any linear equation is y = mx + c
we have m and a point so we can substitute in point (2,21) to find c
21 = 1 x 2 + c
c = 19
therefore, the equation is y = x + 19
