HELP BRAINIST AND POINT

Mathematics
1 answer:
ozzi3 years ago
7 0

Answer:

90 degrees

Step-by-step explanation:

general Pythagoras

c² = a² + b² - 2ab×cos(ABC)

with c being the side opposite of the angle ABC.

c = AC

a = AB

b = BC

(0-15)² + (0-0)² = (0-9.6)² + (0-7.2)² + (9.6-15)² + (7.2-0)² - 2×sqrt((0-9.6)²+(0-7.2)²)×sqrt((9.6-15)²+(7.2-0)²)×cos(ABC)

225 = 92.16 + 51.84 + 29.16 + 51.84 - 2×12×9×cos(ABC)

225 = 144 + 81 - 216×cos(ABC)

225 = 225 - 216×cos(ABC)

0 = cos(ABC)

ABC = 90 degrees

How do I simplify the n^-6*n^3 topic "Negative and Zero Exponents"
Alchen [17]
Since you’re multiplying n^-6 and n^3, you can add the exponents: -6+3 = -3

n^-6 * n^3 = n^-3

If you need to finish without having a negative exponent in your answer, then remember a negative exponent means that factor is on the wrong side of the fraction.

n^-3 = n^-3 / 1 = 1/n^3

when the factor moves to the other side of the fraction, the side of the exponent changes.

lesya [120]

Okay! Let's write out all the numbers:

1

2

3

4

5

6

7

8

9

10

11

12

13

14

15

Now, let's bold (or you can circle them... or do really anything to them as long as they are standing out to you) the even numbers (remember all even numbers are divisible by 2)

1

2

3

4

5

6

7

8

9

10

11

12

13

14

15

Now let's list all the ones we highlighted:

2

4

6

8

10

12

14

Count up how many numbers that is.

You should get 7.

So, our answer is 7 out of 15 numbers.

Or as a fraction:

7/15 is our answer.

Note: A probability is the number of chances something has to happen out of the total number of chances. So in this case the number of even numbers out of the total number of numbers. You can apply this to any probability problem. Hope this helps!
