Notice how the y coordinates of points Z and X are both b. It doesn't matter what the x coordinates are. Because both y coordinates are b, this means we have a horizontal line of slope 0.

For points Y and W, the x coordinate is both 'a'. The y coordinate doesn't matter. Since the x coordinate here is both 'a', we have a vertical line with an undefined slope.

ZX is a completely horizontal line
YW is a completely vertical line
Therefore, the diagonals are perpendicular

Note: we can't use the negative reciprocal idea since there is no reciprocal of 0<span />

Your dog is 8 years younger than your friend. In 2 years, your friend will be three times as old as your dog. How old is your do
ra1l [238]

Answer:

Dog is 2 years old

Step-by-step explanation:

Let dog's age = d

Let friend's age = f

Your dog is 8 years younger than your friend:

d +8 = f

In 2 years, your friend will be three times as old as your dog:

3(d+2) = (f+2)

3d+6 = f+2

3d = f - 4

(sub in f=d+8 from above)

3d = f - 4

3d = d+8 - 4

2d = 4

d = 2

calculates the sum of the first 8 terms of an arithmetic progression starting with 3/5 and ending with 1/4
N76 [4]

We conclude that the sum of the first 8 terms of the arithmetic sequence is 17/5.

<h3>How to get the sum of the first 8 terms?</h3>

In an arithmetic sequence, the difference between any two consecutive terms is a constant.

Here we know that:

a_1 = 3/5\\a_8 = 1/4

There are 7 times the common difference between these two values, so if d is the common difference:

a_1 + 7*d = a_8\\\\3/5 + 7*d = 1/4\\\\7*d = 1/4 - 3/5 = (5 - 12)/20 = -7/20\\\\d = -1/20

Then the sum of the first 8 terms is given by:

3/5 + (3/5 - 1/20) + (3/5 - 2/20) + ... + (3/5 - 7/20)\\\\8*(3/5) - (1/20)*(1 + 2 + 3+ 4 + 5 + 6 + 7) = 3.4 = 34/10 = 17/5

So we conclude that the sum of the first 8 terms of the arithmetic sequence is 17/5.

0.1 *10 = 1

The dog eats 1 pound of food in 10 days.
