Answer:

After t = 4 the rocket will hit the ground.

Step-by-step explanation:

We are given a parametric equation as x = 3t² and y = - 4t + 16.

If we assume that the x is a measure of horizontal distance, y is the measure of vertical distance and t is the time of travel of the rocket, then by making y = 0, we will get the time to hit the ground.

Hence, - 4t + 16 = 0

⇒ t = 4

Therefore, after t = 4 the rocket will hit the ground. (Answer)

65Answer:

we can use sin to find the missing length

Step-by-step explanation:

The ratio states that sin of an angle=opposite/hypotenuse

sin(65)=x/6 since we know the angle and the hypotenuse we need to figure out the opposite side

sin(65)=0.906307...

0.906307=x/6

Multiply 6 on both sides to isolate x

The answer is 5.4378...

Rounded to the hundredth is 5.44

Carmen is an engineer making plans to run a rail line, represented by the transversal t, through a city.

Answer:

$m\angle 1=155\degree$

Step-by-step explanation:

The missing diagram is shown in the attachment.

We need to Examine Carmen’s rail plans to identify the measure of ∠1.

Recall that corresponding angles are equal.

From Carmen’s rail plans, the measure of $\angle 1$ corresponds to 155 degrees because the streets represented by lines V and W are parallel and t is a transversal.
