It's 1,000,000: 

<span>the sum is 1 + 3 + 5 + ... 1999999 </span>

<span>= 1 + 2 + ... + 2000000 - 2*(1 + ... + 1000000) </span>

<span>= 2000000*2000001/2 - 2*(1000000*1000001 / 2) </span>

<span>= 1000000*(2000001 - 1000001) = 1000000000000 (one million million) </span>

<span>and dividing this by one million to get the average, </span>

<span>you get one million</span>

Three corners of a city bloc is located at (2,2) (2,-4) (-5,-4) on a coordinate plane what are the coordinates of the fourth cor
AleksandrR [38]

Answer:

(-5, 2)

Step-by-step explanation:

Three corners of a rectangular city block are located at (2,2), (2,-4) and (-5,-4) on a coordinate plane. What are the coordinates of the fourth Coordinate?

Solution:

A rectangle is a quadrilateral (has four sides and four angles) in which opposite sides are equal and parallel. Also, all the angles are at 90 degrees.

Since the city block is rectangular in shape, therefore the fourth coordinate would have the same y coordinate as the point (2, 2) and it would also have the same x coordinate as (-5, -4).

Hence the fourth coordinate is (-5, 2)

The time it will take the thermometer to hit the ground is 22 seconds

<h3>Calculating Time </h3>

From the question, we are to determine the how long it would take the thermometer to hit the ground

From the given information,

The equation for the height as a function of time is

h(t) = -16t² + initial height

From the given information,

The thermometer falls from a weather balloon at a height of 7744 ft

∴ Initial height = 7744 ft

When the thermometer hits the ground, h(t) = 0

Thus, we get

0 = -16t² + 7744

16t² = 7744

t² = 7744/16

t² = 484

t = √484

t = 22 seconds

Hence, the time it will take the thermometer to hit the ground is 22 seconds
