The diameter of a circle is 8 kilometers. What is the angle measure of an arc ​ kilometers long?
inn [45]
Answer: 14.32 degrees

The circle has a diameter of 8 kilometers, so the perimeter would be:
perimeter= pi * diameter
perimeter= 22/7 * 8 kilometers= <span>25.14 kilometers

A full perimeter </span>of the circle, which is 25.14km,  has 360° angle. So 1km arc would be: 1km/ 25.14 km * 360°= 14.32°

The sum of two numbers is 32. Their difference is 30. What are the two numbers? Show all work
DiKsa [7]

Answer:

a=30 , b = 0

Step-by-step explanation:

let the two numbers be represented as a and b

a + b = 30... eqn 1

a - b = 30 ...... eqn 2

we then add the two equations to get values for a and b

a + b + a - b = 30 + 30

a + b + a -b = 60

2a = 60  ( diivide both sides by 2)

a = 30

we then put value for a = 30 into  any of the equations to get b

a + b = 30,    30 + b= 30

b = 30 -30   , b = 0

to confirm if the answers are correct, we insert the values for a and b in the two equations.

a + b = 30..... eqn 1,      30 + 0 = 30

a - b = 30 ...... eqn 2   ,    30 - 0  = 30

From the table below, determine whether the data shows an exponential function. Explain why or why not.
Anarel [89]

9514 1404 393

Answer:

  b. No; the domain values are not at regular intervals although the range values have a common factor.

Step-by-step explanation:

The differences between x-values are ...

  -1, -1, -1, -2 . . . . not a constant difference

The ratios of y-values are ...

  2/8 = 0.5/2 = 0.125/0.5 = 0.25 . . . . a constant difference

The fact that the domain values do not have a common difference renders the common factor of the range values irrelevant. The relation is not exponential.
