Multiplying it by two 4*2 is 8 and 3*2 is 6
Answer:
Find the highest and lowest terms Figure out where your number line starts and ends. Put the lowest term on the far left and the highest term on the far right. Remember, negative numbers are lower than positive numbers, and the greater a negative number's distance from zero, the lower it is.
Step-by-step explanation:
To solve this we can take two different approaches:
1. We can substitute theta by 30° and evaluate our expression using a calculator:
2. We can use the unitary circle and the fact that
, so we can rewrite our expression as follows:
From our unitary circle we can check that
and
.
Lets replace those values in our expression and simplify:
Either way we can conclude that the correct answer is:
D)8.7
Answer:
5.2
Step-by-step explanation:
√27 = 5.1962 (5s.f.) = 5.2 (2s.f.)
