log4(32) = 2.5
Step-by-step explanation:
Given that,
log4(2) = 0.5
To find: log4(32)
32 can be written as 2 power 5
log4(32) = log4(2^5)
= 5 log4(2)
In the logarithms if there is a power it is multiplied and only the log is applied to the base of the powered term.
Hence,
log4(32) = 5log4(2)
We know that log4(2) = 0.5
So,
log4(32) = 5(0.5)
log4(32) = 2.5
a = -a if a = 0
g(x) is –g(x), then –g(x) = 0
Answer:
The answer is a= 
Step-by-step explanation:
Combine like terms and we get,
divide both sides of the equation by ax, and simplify further,
notice that we can reduce the 24 over 6 1/2,
distribute and simplify further
And a=
Answer:
The slope is -4.5
The slope means that Elijah's phone battery will decrease by 4.5 percent each hour.
Step-by-step explanation:
In the equation y = mx + b, m is the slope.
The coefficient in the equation B = 27 – 4.5t is -4.5. This means that -4.5 is the slope of the equation.
In the context of this problem, the slope will represent the percent that Elijah's phone battery will decrease per hour.
So, the slope means that Elijah's phone battery will decrease by 4.5 percent each hour.
Answer.....15ft by 12ft
Explanation:
Area = Length × Width
180 = LW....make W the subject of formula
;W = 180/L
Perimeter = 2L + 2W
54 = 2L + 2(180/L)...sub W with the formula above...
then simplify the equation and obtain...
2L^2 - 27L + 180 = 0....then solve using the quadratic formula....then obtain..
;L = 15ft....after obtaining L = 15...then substitute into the W = 180/L equation...
where W = 180/15 = 12ft
there you have...Length = 15ft and Width = 12ft
