S_A_V [24]2 years ago
7 0

Answer:

15.22\%

Step-by-step explanation:

The population in 1981 is 46 million.

In 2011, the population increased to 53 million.

The increase in population is (53 -46)million =7 million

Now we express 7 million as a percentage of 46 million

=\frac{7}{46}*100\%

=0.1522*100\%

=15.22%

Lines l and m are parallel.<br> Use the diagram to determine the measure of ∠3.
Pavlova-9 [17]

Answer:

∠3 is 70°

Step-by-step explanation:

∠1 is 50° since it is across from another 50° angle

and then you use the equation x+25+2x+50=180 to find x

x then equals 35°

you then use the alternate interior angle theorem to say that ∠3 is 2x, or 70°

How does the graph of g(x)= 1/x-5+2 compared to the graph of the parent function f(x)=1/x?
Finger [1]

Answer: The graph is shifted to the right by 5 units and shifted up from the parent function.

Step-by-step explanation:

1. By definition, a parent function is the simplest form of a function.

2. You have the following parent function given in the problem:

f(x)=\frac{1}{x}

2. The function g(x) is obtained from the function f(x)

g(x)=\frac{1}{x-5}+2

Where the subtraction of 5 indicates the horizotanl shift to the left and the addition of 2 indicates the vertical shift up.

3. Therefore, keeping the information above on mind, you can conclude that the answer is: the graph is shifted to the right by 5 units and shifted up from the parent function.
