Answer:
This equation has one solution
Step-by-step explanation:
Number of solution depends on the involved variables so here in this equation only one variable involve so one solution exist.
Answer:
B. M-prime (4,-3)
Step-by-step explanation:
When rotated clockwise, point (h,k) is changed to point (k,-h).
Answer:
Step-by-step explanation:
According to the diagram ,
Hypotenuse = 10√3
Opposite = x
Adjacent = y
α = 60
Using SOHCAHTOA ,
Sin α = opp / hyp
Sin 60= x/10√3
√3/2= x/10√3
x = 15
Pythagoras theorem ;
Hypotenuse ^2 = Opposite ^2 +Adjacent ^2
10√3 ^2 = 15^2+ y^2
300 = 225 +y ^2
300 -225 = y^2
75 = y^2
y = √75y
y = 5√3
