Perimeter of a rectangle is
2*width + 2*length
then multiply the perimeter by the cost per foot
2*(150ft) + 2*(200ft)
300ft + 400ft
700ft
700ft * $10/ft
$7000
Answer:
The length of AB is 7.45 units.
Step-by-step explanation:
You can find the length of AB using Cosine Rule, cosθ = adj./hypo. :
θ = 20°
adj. = 7 units
hypo. = AB
cos 20° = 7/AB
AB = 7/cos 20°
= 7.45 units (3s.f)

-y=5-x
Step-by-step explanation:
Answer:
2 by 2
Step-by-step explanation:
Since, given matrix has 2 rows and 2 columns.
So, Its a 2 by 2 order matrix.
The statement gives you the function that models the Area as a function of angle theta, and is telling the value of this angle.
Then, you only need to replace the value of the angle in the function, to obtain the requested area.
<span>A(Θ) = 16 sin Θ • (cos Θ + 1).
Θ = 60°
A(</span>60°<span>) = 16 sin(</span><span>60°) * [cos(</span><span>60°) + 1 ] = 16 * (√3) / 2 * [1/2 + 1] = 8(√3) * 3/2 = 12√3 ≈ 20.79
