How to calculate the circumference

Mathematics
1 answer:
miv72 [106K]3 years ago
3 0
The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle.
If a circle has a diameter of 4, its circumference is 3.14*4=12.56.
If you know the radius, the diameter is twice as large.

Find the mean,median and range of the following list of values and choose the correct result.
Aloiza [94]

Mean: 10.5

Median: 10.5

Range: 5

--------------------------------------------

<u></u>

To find the mean you order the numbers then add then divide.

<u>Add</u>

8+9+10+10+10+11+11+11+12+13=105

<u>Divide</u>

105÷10=10.5

Mean = 10.5

--------------------------------------------

<u></u>

Finding the median essentially involves finding the value in a data sample that has a physical location between the rest of the numbers.

Find the middle number. Put your left finger on 8 and your right finger on 13. Move your left finger to the right to 10 and move your right finger to 11.

the middle number is 10.5 so therefore it is the median.

--------------------------------------------

<u></u>

To find the range you subtract the biggest number to the smallest number.

<u>Subtract</u>

13-8=5

Therefore 5 is the range

Fill in the blank 8(? +3) =48+24
Triss [41]

Answer:

6

Step-by-step explanation:

treat the ? as an x. you need to get it by itself. but first you should distribute the 8.

8x + 24 = 48 +24

8x+24 = 72

take the 24 and subtract it from 72

8x= 48

now divide both sides by 8

x= 6

You have two exponential functions. One function has the formula g(x) = 5 x . The other function has the formula h(x) = 5-x . Wh
AVprozaik [17]
Given the exponential functions g(x)= 5^{x} and h(x)= 5^{-x}

k(x)=(g-h)(x)
k(x)=g(x)-h(x)&#10;
k(x)= 5^{x} - 5^{-x}
k(x)= 5^{x} - \frac{1}{ 5^{x} }
k(x)= \frac{ 5^{x} 5^{x}  }{ 5^{x} } - \frac{1}{ 5^{x} }
k(x)= \frac{ 5^{2x} }{ 5^{x} } - \frac{1}{ 5^{x} }
k(x)= \frac{ 5^{2x}-1 }{ 5^{x} }
