A pendulum is swinging next to a wall. The distance from the bob of the swinging pendulum to the wall varies in a periodic way t

Alekssandra [29.7K]

Answer:

H(t) = 15 -6sin(2.5π(t -0.5))

Step-by-step explanation:

For midline M, amplitude A, period T and time t0 at which the function is decreasing from the midline, the function can be written as ...

H(t) = M -Asin(2π/T(t -t0))

Using the given values of M=15, A=6, T=0.8 and t0 = 0.5, the equation is ...

H(t) = 15 -6sin(2.5π(t -0.5))

Sasha is making custom designs using these small trapezoidal prisms. She wants to cover each of the 8 prisms in her current desi

const2013 [10]

Combined surface area for the 8 prisms is: 3,040 square centimeters.

3,500 cm² > 3,040 cm², therefore, Sasha has enough cloth for the design.

<h3>What is the Surface Area of a Trapezoidal Prism?</h3>

Surface area = (b1 + b2)h + PH

Given the following dimensions:

b1 = 5 cm
b2 = 15 cm
Height of trapezium (h) = 7 cm
Perimeter of trapezium (P) = 15 + 10 + 10 + 5 = 40 cm
Height of prism (H) = 6 cm

Plug in the values into SA = (b1 + b2)h + PH:

Surface area = (5 + 15)7 + (40)(6)

Surface area = 380 sq. cm.

Combined surface area for the 8 prisms = 380 × 8 = 3,040 square centimeters.

3,500 cm² > 3,040 cm², therefore, Sasha has enough cloth.
