It will take you double the time, or 78 seconds.
Answer:
61
Step-by-step explanation:
Answer:
(x*10)/4
Step-by-step explanation:
I think "teo" means ten, so x times 10, divided by 4.
Answer:
90°
Step-by-step explanation:
Circle C has radius √36 = 6
Circle D has radius √18 = 3√2
As the D radius intersecting either point of tangency, does so at a right angle.
The half angle θ between the tangents is
sinθ = 3√2 / 6 = ½√2
θ = 45°
so the angle between the tangents is 2(45) = 90°
Answer:
To find a vector parallel to B, such vector must be a scalar multiple of B.
Step-by-step explanation:
Two non-zero vectors are parallel if they are scalar multiples of one another.
A vector parallel to B must be a scalar multiple of B.
let the vector parallel to B be A, then their scalar multiple is given as;
A = kB
A = k(-2, 3)
where;
k is scalar
Thus, to find a vector parallel to B, such vector must be a scalar multiple of B.
