Find the sum of the first 2,000 positive integers (the numbers 1 through 2000).

MAVERICK [17]3 years ago
6 0

According to Gauss, the formula to find the sum of a series is:

S=n(n+1)/2 where n is the number of terms in the series

Since n=2000, then:

S=2000(2000+1)/2

S=4002000/2

S=2001000

The famous mathematician Gauss had used this same method to find the sum of the digits 1 to 100 while in elementary school. So the sum of the first 2000 positive integers is 2,001,000

Explain why each table determine if y is proportional to x .
lesya692 [45]

Answer:

see explanation

Step-by-step explanation:

If y is proportional to x then the equation relating them is

y = kx ← k is the constant of proportion

To find k divide both sides by x

k = \frac{y}{x}

This value must be constant for all ordered pairs, thus

k = \frac{4}{6} = \frac{2}{3}

k = \frac{6}{9} = \frac{2}{3}

k = \frac{8}{12} = \frac{2}{3}

k = \frac{2}{3}

Since k is constant for all ordered pairs then y is proportional to x

The horizontal distance between two towers is 70m. The angle of depression of the top of the first tower when seen from the top
lana66690 [7]
As shown in the image, we have a 30 degree angle and x, which is what we want. By doing tan30, we can find x, so tan30=x/70 and 70*tan30=x= 70*sqrt(3)/3. 120-x=height of first tower = 120-(70*sqrt(3)/3) = roughly 79.59

Can someone please help<br> Me understand
amid [387]

Answer:

S(8, -8)

T(11, -8)

Step-by-step explanation:

(x, y) are your original position.

They want to to translate it by (x+1, y-4). What this means is you add 1 to your x coordinate, and subtract 4 to your y-coordinate.

S(7, -4) --> S(7+1, -4-4) = S(8, -8)

T(10, -4) --> T(10+1, -4-4) = T(11, -8)

You can do the other two on your own because I don't want to give all the answer to your quiz.
