Answer:
sin(arccos(-4/√25)) = 0.6
Step-by-step explanation:
The expression you want to evaluate is
sin(arccos(-4/√25))
= sin(arccos(-4/5))
We place this expression into a calculator and get the result
arccos(-4/5) = 2.498 rads = 143.1°
then
sin(143.1°) = 3/5
sin(143.1°) = 0.6
sin(arccos(-4/√25)) = 0.6
The next two numbers are -8 and 4 because each number is divided by 2
Answer:
SAS
Step-by-step explanation:
Answer:
the answer is A
Step-by-step explanation:
because 8 divided by 25 (all the beans) is .32
And 12 divided by 25 is .48
So if you subtract .48 by .32 then you get .16
let me know if its right
