Choose all of the correct statements.

Answers

Answer:

1. The diameter is 2 times the Lenght of the radius.

2. C = πd

3. π = C/d

4. d = C/π

5. The circumference is 3.14 times the diameter.

Step-by-step explanation:

Diameter (d) of a circle is 2 times the radius (r). Mathematically, it is written as:

d = 2r

From:

d = 2r

Divide both side by 2

r = d/2

The radius is half the diameter.

Circumference (C) of a circle is given by:

C = 2πr

C = π2r

Recall:

d = 2r

C = πd

C = πd

Divide both side by d

π = C/d

C = πd

Divide both side by π

d = C/π

C = πd

π = 3.14

C = 3.14 × d

Thus, the circumference is 3.14 times the diameter.

SUMMARY:

The correct statement from the above illustration is given below:

1. The diameter is 2 times the Lenght of the radius.

2. C = πd

3. π = C/d

4. d = C/π

5. The circumference is 3.14 times the diameter.

Students in a science class investigated how the speed of sound changes with the air temperature outside. The data are shown in the scatterplot.

Based on the scatterplot, what is the best prediction of the speed of sound when the air temperature is 45°C?

350 m/s

355 m/s

360 m/s

365 m/s

Answers

Answer:360 m/s

Step-by-step explanation:

The best prediction of the speed of sound when the air temperature is 45°C is 360 m/s option third is correct also the graph shows a positive correlation.

What is correlation?

It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.

As we can see in the graph:

When the air temperature is 10°C the speed of sound is around 337m/s

When the air temperature is 20°C the speed of sound is around 344m/s

When the air temperature is 30°C the speed of sound is around 348m/s

When the air temperature is 40°C the speed of sound is around 355m/s

From the above observation, the air temperature increases the speed of the sound increases.

So when the air temperature reaches 45°C the speed of the sound will be 360 m/s.

Thus, the best prediction of the speed of sound when the air temperature is 45°C is 360 m/s.

Answers

Answer: C: 4

Step-by-step explanation:

The domain of the function f(x) is: -6 < x ≤ 4, and the value that is in the domain of the function f(x) is 4

How to determine the value in the domain?

The function is given as:

f(x) = 2x + 5,   -6 < x ≤ 0

f(x) = 2x + 3,   0 < x ≤ 4

The above means that the domain of the function f(x) is:

-6 < x ≤ 0 and 0 < x ≤ 4

When combined, we have:

-6 < x ≤ 4

This means that x is greater than -6 but does not exceed 4

Hence, the value that is in the domain of the function f(x) is 4
