By definition, lines are parallel if they have the same gradient (slope). Any horizontal line has a gradient of 0, so it is parallel to any other horizontal line

Cost of a dozen eggs depends on the size of the eggs. what is the dependent variable?

Answers

the cost of the eggs
cost (x) = x*price
this is an example of a proportional cost relation with the size been x

Answer: the dependent variable is the cost of a dozen of eggs.

Explanation:

The cost is function of the size of the eggs, Cost = f (size).

That means that you introduce the size (this is the input) in the function an you obtain the cost (this is the output)

The input is the independent variable and the output is the dependent variable.

A rocket is launched from the ground. The function h(t)= -4.9t^2 +180t models the height of a rocket launcher from the ground t seconds after it is launched. If all other factors remain the same, which of the following function models the height of a rocket above the ground after t seconds if it is launched from a platform 100 feet in the air?

(1) h(t) = -4.9t^2 +280t

(2) h(t) = -4.9t^2 +180t -100

(3) h(t) = -4.9t^2 +180t +100

(4) h(t) = -4.9t^2 +180 (t+100)

A sailor on Ship A measures the angle between Ship B and the pier and finds it to be 39°. A sailor on Ship B measures the angle between Ship A and the pier and finds that it is 58°. What is the measure of the angle between Ship A and Ship B?The measure between Ship A and Ship B is

Answers

Answer:

$83^(\circ)$

Step-by-step explanation:

Let $C$ be the point that denotes the pier.

$m\angle B=58^(\circ)$

$m\angle A=39^(\circ)$

The angle between A and B is C

$m\angle A+m\angle B+m\angle C=180^(\circ)\n\Rightarrow m\angle C=180^(\circ)-(m\angle A+m\angle B)\n\Rightarrow m\angle C=180^(\circ)-(58^(\circ)+39^(\circ))\n\Rightarrow m\angle C=83^(\circ)$

The measure of the angle between Ship A and Ship B is $83^(\circ)$ .
