Step-by-step explanation:
After putting the values:-
Answer:
None
Step-by-step explanation:
The angles 33+42+66 does not add up to 180 degrees which would not make it a triangle at all.
Answer:
Step-by-step explanation:
<u>Exponential Function</u>
The exponential function can be written with the general equation:
Where A is the value when x=0 and r>0 is the ratio. If r is greater than 1, the function is increasing, if r is less than 1, the function is decreasing.
The table shows the relation between values of x and values of the function y. Note that as x increases (one by one), y decreases with a ratio of 1/2. Only the last two choices have ratios of r=1/2. We only have to test which one of them has the correct value of y=4 when x=0.
Substituting in the third function:
This gives the correct value of f(0)=4.
Substituting in the fourth function:
This choice is wrong
Correct choice:
We are given a table showing the population and the area of different cities, A, B, C and D. To calculate the population density, divide the population over the total area of the city. The following statements are true:
<span>--The population density of City B is greater than that of City C.
--City D has the lowest population density of the four cities.
</span><span>--The population density for City B can be found using the ratio 48,592 : 26.</span><span>
</span><span>

|x| is greater then 5 on |X|>5 and the other x is lees then 5 on |X|<5
