Answer:
D
Step-by-step explanation:
To the nearest 0.5°C means basically 1 digit after the decimal point.
0.5 has 1 digit (5), after the decimal point. To the nearest 0.5 means that the answer should have 1 digit after the decimal point.
For example, if we were to round 14, to the nearest 0.5, we would need to write it as 14.0 (with 1 digit after decimal).
Now, looking at the answer choices, we eliminate A because it has 2 digits after decimal. We eliminate B and C because there is NO DIGIT after decimal. And we accept D, because it has 1 digit after decimal. Hence, this is correct to the nearest 0.5°C.
Answer is D
Answer: i
Step-by-step explanation:
It is imaginary, since if you try squaring numbers, ex: -1, 1,0,2 you always get a number bigger or equal to 0.
For years mathematicans argued weather the square root of -1 (or any negative number) should exist.
Then one day, a mathematician proposed a soulution, the square root of -1 could be i. Everyone liked that and so now the square root of -1 is i
Answer:

Step-by-step explanation:
Answer:
f(1) = 3
Step-by-step explanation:
f(t) = t² - 1t + 3
we want to find f(1)
all we have to do is replace the t's with 1 and evaluate
f(1) = (1)² - 1(1) + 3
evaluate exponent 1² = 1
f(1) = 1 - 1(1) + 3
multiply
f(1) = 1 - 1 + 3
subtract
f(1) = 3
We can start with 364/1000. Then, after simplifying, you get the following:
182/500
91/250.
