I was thinking that the answer could be
2.810; log3 21.903
OR
<span> 2.810; log3 55.2 </span>
So,<span> log5 of 92 is between 2.5 and 3 Correct answer is A</span>
Hi there!
Looks like a lot of work is going on here.
Let's start by solving this equation for the x.
Step 1) Add -20y to both sides.
Step 2) Divide both sides by 5.
Final Answer:
Now, let's solve for y.
Step 1) Add -5x to both sides.
Step 2) Divide both sides by 20.
Final Answer:
Hope this helps! :D
Hint - When you have two variables in an equation, and you want to solve for one, the other will end up in your answer. :)
Answer: B
Step-by-step explanation:
The maximum is 100 and the minimum is 27.
- The only option that shows this is B.
Answer:
x = 2 ±i
Step-by-step explanation:
x^2 = 4x-5
Subtract 4x from each side
x^2 - 4x = 4x-5 -4x
x^2 - 4x= -5
Complete the square
Take the coefficient of the x term, divide by 2 and square it
-4/2 =2 2^2 =4
Add 4 to each side
x^2 -4x+4 = -5 +4
The left side is (x-coefficient of the x term/2)^2
(x-2)^2 = -1
Take the square root of each side
sqrt((x-2)^2) = sqrt(-1)
x-2 = ±i
Add 2 to each side
x-2+2 = 2 ±i
x = 2 ±i
