Let i = sqrt(-1) which is the conventional notation to set up an imaginary number
The idea is to break up the radicand, aka stuff under the square root, to simplify
sqrt(-8) = sqrt(-1*4*2)
sqrt(-8) = sqrt(-1)*sqrt(4)*sqrt(2)
sqrt(-8) = i*2*sqrt(2)
sqrt(-8) = 2i*sqrt(2)
<h3>Answer is choice A</h3>
Answer:
∠A = 22°
Step-by-step explanation:
Given:
We take inverse of sine to find angle A.
So, °
22.23° rounded to nearest whole degree is 22°.
∴ °.
Answer:
14
Step-by-step explanation:
(2 x 6) + ( - 8 ÷ 2^2) =
12 + (4 - 8 ÷ 4)
12 + (4 - 2)
12 + 2
14
Answer:
-4/151
Step-by-step explanation:
We can find the slope by
m = (y2-y1)/*x2-x1)
= (3.6 - 4.8)/(2.65 - -42.65)
= (3.6 - 4.8)/(2.65 +42.65)
= -1.2 / 45.3
-4/151
