What is the slope of (6,0) and (0,8)

1 answer:

8 0

Your answer is 0. The slope formula is m = (y2 - y1) / (x2 - x1). So you do 8-0=8. Then you do 0-6=-6 Then you get 8 over -6. Simplified: -one and one third. That is the answer!

How many terms are there in the sequence 1, 8, 28, 56, ..., 1 ?

BabaBlast [244]

Answer:

9 terms

Step-by-step explanation:

Given:

1, 8, 28, 56, ..., 1

Required

Determine the number of sequence

To determine the number of sequence, we need to understand how the sequence are generated

The sequence are generated using

$\left[\begin{array}{c}n&&r\end{array}\right] = \frac{n!}{(n-r)!r!}$

Where n = 8 and r = 0,1....8

When r = 0

$\left[\begin{array}{c}8&&0\end{array}\right] = \frac{8!}{(8-0)!0!} = \frac{8!}{8!0!} = 1$

When r = 1

$\left[\begin{array}{c}8&&1\end{array}\right] = \frac{8!}{(8-1)!1!} = \frac{8!}{7!1!} = \frac{8 * 7!}{7! * 1} = \frac{8}{1} = 8$

When r = 2

$\left[\begin{array}{c}8&&2\end{array}\right] = \frac{8!}{(8-2)!2!} = \frac{8!}{6!2!} = \frac{8 * 7 * 6!}{6! * 2 *1} = \frac{8 * 7}{2 *1} =2 8$

When r = 3

$\left[\begin{array}{c}8&&3\end{array}\right] = \frac{8!}{(8-3)!3!} = \frac{8!}{5!3!} = \frac{8 * 7 * 6 * 5!}{5! *3* 2 *1} = \frac{8 * 7 * 6}{3 *2 *1} = 56$

When r = 4

$\left[\begin{array}{c}8&&4\end{array}\right] = \frac{8!}{(8-4)!4!} = \frac{8!}{4!3!} = \frac{8 * 7 * 6 * 5 * 4!}{4! *4*3* 2 *1} = \frac{8 * 7 * 6*5}{4*3 *2 *1} = 70$

When r = 5

$\left[\begin{array}{c}8&&5\end{array}\right] = \frac{8!}{(8-5)!5!} = \frac{8!}{5!3!} = \frac{8 * 7 * 6 * 5!}{5! *3* 2 *1} = \frac{8 * 7 * 6}{3 *2 *1} = 56$

When r = 6

$\left[\begin{array}{c}8&&6\end{array}\right] = \frac{8!}{(8-6)!6!} = \frac{8!}{6!2!} = \frac{8 * 7 * 6!}{6! * 2 *1} = \frac{8 * 7}{2 *1} = 28$

When r = 7

$\left[\begin{array}{c}8&&7\end{array}\right] = \frac{8!}{(8-7)!7!} = \frac{8!}{7!1!} = \frac{8 * 7!}{7! * 1} = \frac{8}{1} = 8$

When r = 8

$\left[\begin{array}{c}8&&8\end{array}\right] = \frac{8!}{(8-8)!8!} = \frac{8!}{8!0!} = 1$

The full sequence is: 1,8,28,56,70,56,28,8,1

And the number of terms is 9

7 1/5 - 6 2/5= <br> a. 1 1/5<br> b. 1 4/5<br> c. 13 3/5<br> d. 4/5

stira [4]

Answer:

4/5

Step-by-step explanation:

Simplify the following:

7 + 1/5 - (6 + 2/5)

Put 6 + 2/5 over the common denominator 5. 6 + 2/5 = (5×6)/5 + 2/5:

7 + 1/5 - (5×6)/5 + 2/5

5×6 = 30:

7 + 1/5 - (30/5 + 2/5)

30/5 + 2/5 = (30 + 2)/5:

7 + 1/5 - (30 + 2)/5

30 + 2 = 32:

7 + 1/5 - 32/5

Put 7 + 1/5 - 32/5 over the common denominator 5. 7 + 1/5 - 32/5 = (5×7)/5 + 1/5 - 32/5:

(5×7)/5 + 1/5 - 32/5

5×7 = 35:

35/5 + 1/5 - 32/5

35/5 + 1/5 - 32/5 = (35 + 1 - 32)/5:

(35 + 1 - 32)/5

35 + 1 = 36:

(36 - 32)/5
