Hello
5^(2x) = 27
if : a>0 and b>0 a = b <span>equivalent to log(a) = log (b)
</span> log (5^(2x)) = log(27) ... (1)
a>0 and b>0 log(a^n) = nlog(a)
(1) equivalent to :<span>2x log 5 = log 27</span>
Answer: 54 cm
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Perimeter of a square = side length x4
Replacing with the values given:
72 = 4 s
Solving for s (side length)
72/4=s
s = 18 cm
Since the side length of the square is the length of each rod, and all the rods have the same length, to obtain the perimeter of the triangle we have to apply:
Perimeter of an equilateral triangle: 3 side length
P = 3 (18 ) = 54 cm
Feel free to ask for more if needed or if you did not understand something.
Answer:
number of wooden signs per week.
Step-by-step explanation:
Given:
- denotes signs painted per hour.
-- denotes number of hours worked per week.
#In the function composition, if we have 2 functions and then implies applying then respectively to the results of function y.
-Given the function , we first apply which denotes hours/week and apply function s on the results of .
-Hence, the units of measurement will be number of wooden signs per week.
4x-8 = 31
4x = 31 + 8
4x = 39
x = 9.75
