Yes, I'm relatively sure any number can be written in scientific notation.
Answer:
−224
Step-by-step explanation:
−7(7+9)−7(7+9)
=(−7)(16)−7(7+9)
=−112−7(7+9)
=−112−(7)(16)
=−112−112
=−224
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.
Answer:
90° - COD
Step-by-step explanation:
Because if it's complementary, the mystery angle and COD add up to 90°
