The length of side c will be 2 m.
Answer:
|F net| = 20.22 N
θ ≈ 19.8°
Step-by-step explanation:
F net = 15N i + 8cos(60°)N i + 8sin(60°)N j
= 15N i + 8×½N i + 8×√3/2N j
= 15N i + 4N i + 4√3N j
= 19N i + 4√3N j
|F net| = √(19²+(4√3)²) = √(361+48) = √409 ≈ 20.22N
tan(θ) = 4√3 ÷ 19 ≈ 0.36 → θ ≈ arctan(0.36) = 19.8°
The answer is B. You are getting rid of one x is the answer is x^2.
Answer:
44 square feet were used to build the aquarium
Step-by-step explanation:
∵ The area of the rectangular prism = Lateral area + 2 Base area
∵ The top of the aquarium is open
∴ The area of the aquarium = Lateral area + Base area
∵ Lateral area = perimeter of base × height
∵ Its base is a rectangle
∵ The dimensions of the base are 4 feet and 2 feet
∵ Its height = 3 feet
∴ Perimeter of the base = 2(4 + 2) = 12 feet
∴ Area of the base = 4 × 2 = 8 feet²
∴ Area of aquarium = 12 × 3 + 8 = 36 + 8 = 44 feet²
