This would be an exponential function.
Exponential functions are of the form
y = a*bˣ, where a is the initial value, b is the rate the function changes by, and x is the time period. Since this triples, b would be 3.
Answer:
f=60 , c=30
Step-by-step explanation:
there are 2f and 2c in the graph and f=2c
So
f+f+c+c=180
2c+2c+c+c=180
6c=180
c=180/6
c=30
f=2c
f=2×30
f=60
Answer:
17/24
Step-by-step explanation:
Change the denominators to match
8/24 + 9/24 = 17/24
Answer: Choice B) Integers include whole numbers and natural numbers.
======================================================
Explanation:
Let's go through the four answer choices to see which are true or false.
- A) False. A rational number like 2/3 is not a natural number (1,2,3,4,...). This is one counterexample out of infinitely many.
- B) True. The set of integers is {..., -3, -2, -1, 0, 1, 2, 3, ...} basically positive and negative values that don't have fractional or decimal components. Zero is included.
- C) False. Similar reasoning as choice A above.
- D) False. A natural number like 7 can be written as 7/1, which means it is a rational number. Any rational number is of the form a/b with a,b being integers and b is nonzero.
The answer is A hope it helps
