Answer:
Incorrect
Step-by-step explanation:
Juanita is incorrect because she shouldn't be using 2 squared.
Answer:
x = 0.25
Step-by-step explanation:
When logs are added together, they are actually multiplied and then the logs taken of the product.
That sentence is actually correct, but you are going to have to read it a couple of times. You might understand it if I actually just solve the problem.
ln(2x) + ln(2) = 0 Combine the two subjects to make 1 ln.
ln (2)(2x) = 0 Now take the antilog
ln(4x) = 0
antilog ln(4x) = e^0 e^0 = 1
4x = 1 See your last problem.
x = 1/4
Now the question is "What's the answer?" It might be 1/4 but I doubt it. A better choice would be x = 1/4 or x = 0.25
I'd try the last one first.
Use the Pythagorean theorem a^2 + b^2 = c^2
45^2 + 80^2 = c^2
2025 + 6400 = c^2
c^2 = 8425
c = √8425
c = 91.787
Rounded to the nearest foot = 92 feet
I hope this helps you
x^3= -8^3
x= -8
Step-by-step explanation:
for mixed number to a improper fraction you take the whole number and times that by the denominator and add the numeriator
for example
8 x 8 = 64
64 + 3 = 67
and after you get your last number (67) you put that over your original denominator which is 8 so it would be
for the improper to mixed you see how many times you denominator goes into your numerator
another example is
7 goes into 13 twice so your whole number is 2 and you have a remaining 1 so it would look like
