Answer:
The value of q are 0.781,-1.281.
Step-by-step explanation:
Given : Two vectors
and
are perpendicular to each other.
To find : The value of q ?
Solution :
When two vectors are perpendicular to each other then their dot product is zero.
i.e. 
Two vectors
and





Using quadratic formula,




Therefore, The value of q are 0.781,-1.281.
Answer:
D -24/25
Step-by-step explanation:
sin(2x) = 2sin(x)cos(x)
cos(x) = ⅘
sin²(x) = 1 - cos²(x) = 1 - (⅘)²
sin²(x) = 9/25
sin(x) = -⅗
(Because 4th quadrant)
sin(2x) = 2(-⅗)(⅘)
= -24/25
Answer:
y = -x +3
Step-by-step explanation:
Think about the Y= mx + b
m = -1 so it's -x
b = 3, so it's +3
y intercept goes after the slope:
Y= Mx + B
Y = -x + 3
