Answer:
B) Sin^-1(-1) = 3pi/2 or 270°
D) Sin^-1(-1) = -pi/2 or -90°
Step-by-step explanation:
Sine function:
The sine function is -1 at 270º(-90º), which is 3pi/2 = -pi/2.
Inverse sine:
The input of the inverse sine function is a value, and the output are the angles which have the sine equal to the input.
Sin^-1(-1)
Angles for which the sine are -1, that is 3pi/2 or 270° and -pi/2 or -90°. Thus, options B and D are correct.
Answer:
3.6 cm
Step-by-step explanation:
<u>Triangle Proportionality Theorem</u>
BD : DE = BA : AC
⇒ 6 : 10 = BA : 16
⇒ 
⇒ 
⇒ BA = 9.6
AD = BA - BD
⇒ AD = 9.6 - 6 = 3.6 cm
Answer:-10m^2 n^7
Step-by-step explanation:
Answer:
Step-by-step explanation:
h = √6 units
b = √9 units
A = b*h/2 = √6·√9 /2 = √(6·9)/2 = √(2·3·3·3)/2 = 3√3 /2 units ²≈ 2.6 units²
