Answer:
30
Step-by-step explanation:
A=p(1+i/m)^mn
A=11,700×(1+0.039÷4)^(4×18)
A=23,527.94

Answer:
61.5°
Step-by-step explanation:
The tangent relation is useful here. The angle is opposite the vertical side and adjacent to the horizontal side of the right triangle.
Tan = Opposite/Adjacent
tan(α) = 35/19
α = arctan(35/19) ≈ 61.5°
The angle made by <em>v</em> and the positive x-axis is 61.5°.
Answer:
B.) Orthogonal
Step-by-step explanation:
Two vectors u and v whose dot product is u·v=0 are said to be orthogonal
u = <6, -2>, v = <2, 6>
u·v = u1*v1 + u2*v2
6*2 + -2 * 6
=12 -12
=0
