Step-by-step explanation:

Given the function

f\left(x\right)=(1)/(2)\cdot 2^x

  • Putting x = -2

(1)/(2)\cdot \:2^(-2)=(1)/(2)\cdot (1)/(4)=(1)/(8)

so

(x, f(x)) will be (-2, 1/8)

  • Putting x = -1

(1)/(2)\cdot \:\:2^(-1)=(1)/(2)\cdot \:(1)/(2)=(1)/(4)

so

(x, f(x)) will be (-1, 1/4)

  • Putting x = 0

(1)/(2)\cdot \:2^0=(1)/(2)

so

(x, f(x)) will be (0, 1/2)

  • Putting x = 1

(1)/(2)\cdot \:\:2^1=2\cdot \:(1)/(2)=1

so

(x, f(x)) will be (1, 1)

  • Putting x = 2

(1)/(2)\cdot \:\:2^2=4\cdot \:(1)/(2)=2

so

(x, f(x)) will be (2, 2)

Why can't a triangle have more than one obtuse angle

Answers

An "obtuse" angle is an angle that's bigger than 90 degrees.
So two obtuse angles would add up to more than 180 degrees.

But the three angles inside a triangle always add up to exactly 180 degrees.
So two of them can't be obtuse.

7m+8=71 how do I answer this question it's a two-step equation ​

Answers

Answer:

m=9

Step-by-step explanation:

It's very simple.

First, you have to subtract 8 to both sides.

7m+8=71

      -8  -8

Then, once you've subtracted, your left with 7m= 63. Now you have to divide to both sides.

7m= 63

  7     7

In conclusion, once you've divided, you are left with your answer.

m=9

Answer:m=9

Step-by-step explanation:

Subtract 8 from 8 and 71 so 8 cancels out and 71-8=63 63/7=m. 7m+8=71

-8. -8

7m=63

/7. /7

M=9

A student skipped a step when she tried to convert 18 hours into seconds,and she got the following incorrect result:
18 hours
60 seconds)
= 1080 seconds
1 minute
What conversion ratio did she skip in this multiple-step conversion?

Answers

Answer:

The conversion of minutes to seconds is skipped in multiple-step conversion.

Step-by-step explanation:

Given:

To convert 18 hours into seconds.

Now, to get the conversion ratio skip in this multiple-step conversion.

First we need to convert hours into minutes:

1 hour = 60 minutes.

So, 18 hours = 18* 60 minutes

                     = 1080 minutes.

Then, we convert minutes into seconds:

1 minute = 60 seconds.

So, 1080 minutes = 1080* 60 seconds

                             =  64800 seconds.

Thus, 18 hours =  64800 seconds.

As given in question the conversion from hours to seconds is there but the conversion of minutes to second is not there it is skipped so the result is incorrect.

Therefore, the conversion of minutes to seconds is skipped in multiple-step conversion.
