Jerry writes down all the odd numbers $1, 3, 5, 7, \dots,$ up to $999$. what is the sum of all the numbers he writes down?

Pavel [41]

The sum of n odd numbers n², where n is a natural number and represents the number of terms.

<h3>What is a natural number?</h3>

The numbers that we use when we are counting or ordering, which occurs commonly and obviously in nature.

Here, given all the odd numbers from 1,3,5,7..........999.

The sum of n odd numbers, n².

999² = 998001

Thus, the sum of all the odd numbers from 1 to 999 is 998001.

Lydia graphed δlmn at the coordinates l (0, 0), m (2, 2), and n (2, −1). She thinks δlmn is a right triangle. Is lydia's asserti

nadya68 [22]

No product results in -1, hence δlmn is NOT a right triangle showing that lydia's assertion is incorrect

<h3>Perpendicular lines</h3>

In order to determine whether triangle lmn is right-angled, we need to determine the slope of lm, ln, and mn first as shown:

For the slope of lm:

$m_{lm} = \frac{2-0}{2-0}\\ m_{lm} =2/2\\m_{lm} =1$

For the slope of ln:

$m_{ln} = \frac{-1-0}{2-0}\\m_{ln} =-1/2\\$

For the slope of mn:

$m_{mn} = \frac{-1-2}{2-2}\\m_{ln} =-3/0 = \infty\\$

If any of the two lines is perpendicular, hence the triangle lmn is right-angled.

To check, we will take the product of the slopes and see if it is equivalent to -1.

Product of slope lm and ln

$m_{lm}\times m_{ln} = 1 \times -1/2\\m_{lm}\times m_{ln} = -1/2$

Since no product results in -1, hence δlmn is NOT a right triangle showing that Lydia's assertion is incorrect

He said he (be) sorry he (gave) me so much trouble.

lisov135 [29]

The correct grammar for this sentence is replacing (be/was) and (gave/got). *** read your sentence out loud to know the difference when saying it!
