In rectangles all sides are either perpendicular or parallel, so you know that the missing side is equal to the bottom 2 horizontal sides added up.

4 + 7 = 11.

The missing side is 11cm.

(01.04 MC)The elevation of city A is 80 feet below sea level; the elevation of city C is 16 feet below sea level. The elevation

fomenos

A) The expression to represent the elevation in feet of city D is; ¹/₂ × (-16) ft

B) The solution to the expression of the elevation of City D is; -8 fr which is negative because it falls below sea level.

First of all, sea level is at 0 ft.

Thus;

If city A has an elevation of 80 ft below sea level, then;

Elevation of city A = -80 ft

The elevation of city C is 16 feet below sea level. Thus;

Elevation of city C = -16 ft

A) The elevation of city D is ¹/₂ of the elevation of city C. Thus;

Expression for Elevation of city D = ¹/₂ × (-16)

B) Solving the expression for elevation of city D gives;

Elevation of City D = -8 ft

The reason why the answer is negative is because any distance below sea level is considered to be negative and city C which is twice the elevation of city D is negative, and so city D must also have a negative elevation.

John recorded the number of cars passing a traffic signal at intervals of 2 minutes.

Sedaia [141]

The image relating to the question can be found in the picture attached below.

Answer:

y - intercept = 0

Slope of line = 2.86

Step-by-step explanation:

THE y-intercept is the point on the y - axis where the line crosses the y - axis. The y-intercept of the graph is 0.

The slope of the line is the ratio of change in the y-axis to the x - axis.

Gradient / slope = Δy / Δx = (y2 - y1) / (x2 - x1)

Drawing a right angle triangle at any point on to meet the line of best fit :

y2 = 35, y1 = 15, x2 = 12, x1 = 5

Slope = (y2 - y1) / (x2 - x1) = (35 - 15) / (12 - 5)

Slope = 20 / 7 = 2.857

Slope = 2.86

In physics, if a moving object has a starting position at s 0, an initial velocity of v 0, and a constant acceleration a, then t

stiks02 [169]

Actually the position function with respect to time under constant acceleration is:

a=g

v=⌠g dt

v=gt+vi

s=⌠v

s=gt^2/2+vit+si

So if vi and si are zero then you just have:

s=gt^2/2

Notice that it is not gt^2 but (g/2) t^2

So the first term in any quadratic is half of the acceleration times time squared because of how the integration works out...

Anyway....

sf=(a/2)t^2+vit+si

(sf-si)-vit=a(t^2)/2

2(sf-si)-2vit=at^2

a=(2(sf-si)-2vit)/t^2 and if si and vi equal zero

a=(2s)/t^2
