Use a double angle identity to rewrite the formula r(Θ)=<img src="https://tex.z-dn.net/?f=1%2F16v%5E2sin%28theta%29cos%28theta%2
Artist 52 [7]

Answer:

1/32v²sin2θ

Step-by-step explanation:

Given the expression r(theta) = 1/16v²sinθcosθ

According to double angle of trigonometry identity;

Sin2θ = sin(θ+θ)

Sin2θ = sinθcosθ + cosθsinθ

Sin2θ = 2sinθcosθ

sinθcosθ = sin2θ/2 ... **

Substituting equation ** into the question

1/16v²sinθcosθ = 1/16v²(sin2θ/2)

1/16v²sinθcosθ = 1/2×1/16v²(sin2θ)

1/16v²sinθcosθ = 1/32v²sin2θ

Hence using the double angle identity, the equivalent expression is 1/32v²sin2θ

If a square has an area of 196 square feet. what is the perimeter of the sandbox?
IRINA_888 [86]
The area of a rectangular shape is found my multiplying the base x height. Since squares have the same measure all the way around the base must be equal to height so b x h for a square is equal to (b x b)=b^2 or (h x h)^2 they are the same to using b for base we have b^2=196 so sqrt(196) = each side is 14sqft. To find the perimeter we just add all the sides to get (14+14+14+14) or (14*4)= 56sqft.
