Answer:

**Answer:**

x + (4x-85) = 90

**Step-by-step explanation:**

The two angles are complementary which means they add to 90 degrees

x + (4x-85) = 90

Answer:

**Answer: A **

**Step-by-step explanation:**

Both angles are makes a right angle which adds up to 90 degrees so they both have to add up to 90 degrees.

The particle passes through the **origin** at *t = 0* and *t = ±√20*. The particle is instantaneously motionless at *t = 0* and *t = ±√10*.

**(a) **To determine the times at which the particle passes through the origin, we need to find when the position function equals zero. So, we set *s(t) = 0* and solve for *t*.*t**4** - 20t**2** = 0*

Factoring out a *t**2*, we get:*t**2**(t**2** - 20) = 0*

Setting each factor equal to zero and solving for *t* gives us the following solutions:*t = 0* (giving us the initial position), and *t = ±√20* (approximately *t = ±4.47*).

**(b) **To determine when the particle is **instantaneously** motionless, we need to find when the velocity of the particle is equal to zero. The velocity function of the particle is the derivative of the position function. So, we differentiate *s(t)* with respect to *t* to find the velocity function.*v(t) = s'(t) = 4t³ -40t*

Setting *v(t) = 0*, we have:*4t³ -40t = 0*

Factoring out a *4t*, we get:*4t(t² - 10) = 0*

Setting each factor equal to zero and solving for *t* gives us the following solutions:*t = 0* (giving us the initial velocity), and *t = ±√10* (approximately *t = ±3.16*).

The particle passes through the origin at t = 0 and t = √20 seconds. The particle is instantaneously motionless at t = 0 and t = ±√10 seconds.

The position of the particle at time t is given by the equation s(t) = t4 - 20t2. To determine the times when the particle passes through the origin, we set s(t) equal to zero and solve for t. This gives us the quadratic equation t4 - 20t2 = 0, which can be factored as t2(t2 - 20) = 0. The solutions to this equation are t = 0 and t = ±√20. Since t cannot be negative in this scenario, the particle passes through the origin at t = 0 and t = √20 seconds.

To determine the times when the particle is instantaneously motionless, we need to find the times when the velocity of the particle is equal to zero. The velocity of the particle can be found by taking the derivative of the position function with respect to time, v(t) = 4t3 - 40t. Setting this equation equal to zero and solving for t gives us the cubic equation 4t3 - 40t = 0. This equation can be factored as 4t(t2 - 10) = 0. The solutions to this equation are t = 0 and t = ±√10. Therefore, the particle is instantaneously motionless at t = 0 and t = ±√10 seconds.

2/3 x +10/60 =100/60

**Answer:**

2 1/4

**Step-by-step explanation:**

subtract 10/60 from each side to get:

2/3x = 90/60

multiply each side by 3/2 to get:

x = 270/120

x = 27/12 or 2 1/4
