Answer:
B. The functions f(x) and g(x) are reflections over the y-axis.
Step-by-step explanation:
From the information given the table appears as;
x f(x)=2^x g(x)=0.5^x
2 4 0.25
1 2 0.5
0 1 1
-1 0.5 2
-2 0.25 4
Plotting the two graphs to view the trends;
In the graph of f(x)=2^x against x you notice a curve with increasing positive slope.
In the graph of g(x)=0.5^x against x you notice a curve with a negative slope that is increasing.
In combining both graphs you notice that f(x) and g(x) are reflections over the y-axis.
Correct answer is ;The functions f(x) and g(x) are reflections over the y-axis.
Answer: x=23 degrees
Step by step: 90-67=23
Perform indicated multiplications on left side.
8-40x=13 subtract 8 from both sides
-40x=5 divide both sides by -40
x=-5/40
x=-1/8
Note: There are no mixed numbers in this problem.
You are given the
length of the chain equal to 28.9cm. For each link, the length is 1.7cm long. You
are required to find how many links are there in the chain. You just divide
28.9 cm by 1.7 cm to get the answer. The solution is,
<span>
Number of links =
chain length/link length</span>
Number of links = (28.9cm)/(1.7cm)
<span>Number of links =
chain length/link length</span>
Number of links = 17
<span><u><span>There are 17
links in a 28.9cm chain length.</span></u><u /></span>
