Answer:

15x + 14y = -18

Step-by-step explanation:

slope = (6 - -9)/(-8 - 6) = 15/-14

y = mx + b

6 = -15/14(-8) + b

6 = 60/7 + b

b = -18/7

y = -15/14x - 18/7

15/14x + y = -18/7, multiply everything by 14

15x + 14y = -18

An object moves in simple harmonic motion with period 8 seconds and amplitude 6 cm. At time t = 0 seconds, its displacement d fr
Vladimir79 [104]

In the equation model, the simple harmonic motion is d=6sin(πt/4)-6 if the object moves in simple harmonic motion with a period of 8 seconds and amplitude of 6 cm.

<h3>What is simple harmonic motion?</h3>

Simple Harmonic Motion is described as a motion in which the restoring force is proportionate to the body's displacement from its mean position.

We have:

Amplitude A = 6 cm

Time period = 8 seconds

T = 2π/w

8 = 2π/w

w = π/4

Its displacement d from rest is -6 cm, and initially, it moves in a positive direction.

d(0) = -6 cm at t = 0

The equation becomes:

\rm d = 6sin(\dfrac{\pi}{4}t)-6

Thus, in the equation model, the simple harmonic motion is d=6sin(πt/4)-6 if the object moves in simple harmonic motion with a period of 8 seconds and amplitude of 6 cm.

Tung rotates a square around its horizontal axis of symmetry to make a solid figure. What is the shape of the vertical cross sec
Iteru [2.4K]

The shape of the vertical cross section of the solid figure is Circle , Option A is the right answer.

What is a Circle ?

A circle is a round figure with all the points lying in the same plane .

It is given that

Tung rotates a square around its horizontal axis of symmetry to make a solid figure.

the shape of the vertical cross section of the solid figure will be a circle that can be seen in the image attached

The rotation image is also attached and the horizontal axis is taken as straight to show the formation of a circle.

Therefore Option A is the right answer.
