ASAP BRAINLIEST!!!!! 2. Dave leaves his office in Padelford Hall on his way to teach in Gould Hall. Below are several different

scenarios. Assume Dave’s path to Gould Hall is along a straight line which is 2400 feet long.
scenarios;

I. Dave leaves Padelford Hall and walks at a constant spend until he reaches Gould Hall 10 minutes later.

II. Dave leaves Padelford Hall and walks at a constant speed. It takes him 6 minutes to reach the halfway point. Then he gets confused and stops for 1 minute. He then continues on to Gould Hall at the same constant speed he had when he originally left Padelford Hall.

III. Dave leaves Padelford Hall and walks at a constant speed. It takes him 6 minutes to reach the half-way point. Then he gets confused and stops for 1 minute to figure out where he is. Dave then continues on to Gould Hall at twice the constant speed he had when he originally left Padelford Hall. On a sheet of paper, sketch a graph of these situation and use your graph to answer the following questions:

A. Compare and contrast the graph from before the 1-minute pause to the graph after the pause. What are the similarities and/or differences?

B. Using all three sketches, in which scenario does Dave reach Gould Hall fastest? How do you know?

C. Using all three scenarios, represent each scenario as an algebraic function.

The diameter of Circle Q terminates on the circumference of the circle at (3,0) and (3,-7) . Write the equation of the circle in
Deffense [45]

Step-by-step explanation:

The center of a circle with 2 end points of a di diameter is the midpoint of the two endpoints.

The formula needed to find the minpoints is

(x,y) = (x2 + x1)/2, (y2 + y1)/2

x2 = 3

x1 = 3

y2 = 0

y1 = -7

midpoint = (3 + 3)/2, (0 - 7)/2

midp[oint = 3,-3.5

The midpoint is the center of the circle. Observe that the signs get changed when entering the values for (x,y)

So far what you have is (x - 3)^2 + (y + 3.5)^2 = r^2

To determine r^2 you need only take the distance from the center to oneof the endpoints.

r^2 = (3 - 3)^2 + (3.5 - 0)^2

r^2 = 3.5^2

r^2 = 12.25

Answer: (x - 3)^2 + (y + 3.5)^2 = 12.25

Find the value of x and y. y=2x and 1.85x+3.7y=12.95
Len [333]

Answer:

x=1.4 y=2.8

Step-by-step explanation:

Lets substitute y with 2x. We get: 1.85x+7.4x=12.95.

Simplifying by combining x: 9.25x=12.95

Then you just divide 12.95 by 9.25: x=1.4

Now for y. We know why is 2x so we just have to multiply x by 2: y=2x, y=2.8.
