Answer:
0.01
Step-by-step explanation:
If you convert 10 into a decimal it's just 0.1, multiply 0.1 by itself only one time because the exponent is 2 and you get 0.01
Answer:
42 - (-24) = 66
Step-by-step explanation:
I'm not sure if this is the form of answer, but if you're subtracting a negative from a negative, you're adding a positive, so this is another way to write the expression.
Answer: 10+8i
Step-by-step explanation:
To subtract the expressions, you would first need to distribute the -1.
(8+7i)-(-2-i) [distribute -1]
8+7i+2+i [combine like terms]
10+8i
Now, we have the subtracted answer 10+8i.
Remaining angle = 180-90-60=30
by sine rule
8/sin30 = x/sin90
x = 8/0.5=16
I would say the answer is b, because it states -4 + 4 = 0
