A lake near the Arctic Circle is covered by a 222-meter-thick sheet of ice during the cold winter months. When spring arrives, t
masha68 [24]

Here we must see which information about the graph of a linear relationship is given.  The information given is just the y-intercept and a point that is not an intercept, thus the correct option is E.

<h3>Linear relationships:</h3>

So we define a general linear relationship as:

y = a*x + b

Where a is the slope and b is the y-intercept.

In this problem we know that:

  • Originally, the sheet of ice is 2 meters thick.
  • The thickness decays at a constant rate
  • After 3 weeks, the thickness is 1.25 meters.

The first point gives us the y-intercept (the thickness at week 0), the second one gives us the fact that the relationship is linear, and the third one is just a point on the line (that can be used to get the slope.)

So the information given is just the y-intercept and a point that is not an intercept, thus the correct option is E.

Maple town is 16 kilometers due north of the airport and sachet town is due east of the airport. The shortest distance between m
Alexxandr [17]

Answer:

Sachet town is 12km from the airport

Step-by-step explanation:

In this question, we are asked to calculate the distance from sachet town to the airport.

This can be calculated by referring to a diagrammatic representation. Please check attached file.

Let’s proceed with the calculations however.

From the question, we can see that we have formed a Right angled triangle from the diagram and we need to calculate the distance x.

Mathematically;

x^2 + 16^2 = 20^2

x^2 = 20^2 - 16^2

x^2 = 400 - 256

x^2 = 144

x = sq.rt of 144

x = 12km
