Answer:
7
Step-by-step explanation:
Given the information from the question:

Next we can use the order of operations to find the value of the expression.

The definition of a function is a relation where every input (x value) is paired with exactly one output (y-value).
A. Not a function, because you have (300, 9) and (300,7). The x-value 300 is paired with two different y-values, 9 and 7.
B. Not a function. (260, 4) and (260, 2)
C. Is a function
D. Not a function. (225, 4) and (225, 2)
Answer:
72 cents
Step-by-step explanation:
We can set up an equation.
.05 * 2^(n-1)
n being the nth term in the sequence
Plug in and solve.
.05 * 2^(20-1)
.05 * 2^19
.05 * 524, 288
The 20th term would be 262, 144.
Answer:
89 km
Step-by-step explanation:
a^2+b^2=c^2
80^2+39^2=c^2
6400+1521=c^2
7921=c^2
sqrt of 7921=89
