Clara says that if you square the number 4 and then divide the result by​ 2, you end up with 4. Is Clara​ correct? Explain. Please help.

Answers

Answer 1

Answer:

She is incorrect

Step-by-step explanation:

If you square 4 you get 16 and divide 16 and 2 you get 8 so shes wrong.

Answer 2

Answer: Clara is incorrect

Step-by-step explanation:

The square root of 4 is 2

2 ÷ 2 = 1

You end up with 1 not 4, therefore, Clara is wrong.

Edit: Look at the other answer, I sadly made a mistake thinking the question said square root but it said square I apologize .

How do you solve this equation? (k/4 is a fraction)

5 = 12 + k/4

Answers

Subtract 12 from both sides

5 - 12 = k/4

Simplify 5 - 12 to -7

-7 = k/4

Multiply both sides by 4

-7 * 4 = k

Simplify -7 * 4 to -28

-28 = k

Switch sides

k = -28

7y-9=3y+27 y= please help!

Answers

Answer:

Y=9

Step-by-step explanation:

Single out the variable, so subtract 3y from both sides.

7y-9-3y=3y+27-3y

4y-9=27

Then move the value to one side, so add 9 to both sides.

4y-9+9=27+9

4y=36

Then divide 36 by 4

4y/4=36/4

Two samples were taken of fish caught on Small Lake and are shown in the table below. It is estimated that the Small Lake fish population is roughly 1,000 fish. What is the average number of brown trout in the lake? Small Lake Fish Sample 15 Sample 1 Rainbow Trout Brown Trout Largemouth Bass 11 Sample 2 Rainbow Trout Brown Trout Largemouth Bass 3 1 9 11 43 ООО 80 160 333.​

Answers

Answer:

b or 80

Step-by-step explanation:

80 is the average number of brown trout in the lake.

What is Mean?

The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.

given, Two samples were taken of fish caught on Small Lake and are shown in the table given.

Total fish were taken in both samples = 9 + 3+ 15 + 11 + 1 + 11

Total fish were taken in both samples = 50

Brown fish in both samples = 3 + 1

Brown fish in both samples = 4

Thus,

the average number of brown trout in the lake = 4/50 * 1000

Since there are 1000 fish in total in the lake

the average number of brown trout in the lake = 80

Therefore,  the average number of brown trout in the lake is 80.

You need a piece of paper to measure 64 Dash 25 cylinders if you take two together that each measure 38.4 silver meters how much do you need to cut off

Answers

Answer:

The length needed to cut off is 12.55 cm

Step-by-step explanation:

The corrected question is:

you need a piece of paper to measure 64.25 cm. If you tape two together that each measure 38.4 cm, how much do you need to cut off?

Solution:

measurement/length of each paper piece = 38.4 cm

measurement/ length required = 64.25 cm

If length of one paper piece is 38.4 cm then if we tape 2 pieces together then the measurement or length is calculated as:

38.4 + 38.4 = 76.8 cm

So to calculate how much we need to cut off:

length required to cutoff = total length of two pieces - length  required

                                         = 76.8 - 64.25

                                         = 12.55 cm

So the length required to cut off is 12.55 cm

If f(x) = 8.3x + 8.1, solve f(x) = 65.37. Type your answer as a decimal rounded to the nearest tenth.

Answers

Answer:

The answer is 6.9

Step-by-step explanation:

f(x) = 8.3x + 8.1

To solve f(x) = 65.37 , equate f(x) to 65.37 and solve for the value of x

That's

8.3x + 8.1 = 65.37

Subtract 8.1 from both sides

That's

8.3x + 8.1 - 8.1 = 65.37 - 8.1

8.3x = 57.27

Divide both sides by 8.3

[tex] \frac{8.3x}{8.3} = \frac{57.27}{8.3} \\ x = 6.896385[/tex]

We have the final answer as

6.9 to the nearest tenth

d is the correct answer i believe is right

The function (f·g)(x) is -2x³-8x²and the function (g·f)(x) is -2x³-8x². Therefore, the correct answer is option A.

What is the function?

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

The given functions are f(x)=-2x² and g(x)=x+4.

Now, (f·g)(x)=f(x)×g(x)

= -2x² ×(x+4)

(f·g)(x)= -2x³-8x²

Here, (g·f)(x)=g(x)×f(x)

= (x+4)×(-2x²)

(g·f)(x)= -2x³-8x²

Therefore, option A is the correct answer.
