The only increasing function is the last option:
<h3>
Which function is increasing?</h3>
Here we only need to see that, is as x increases also do f(x). Then the function will be increasing.
The cases for exponential functions is actually more trivial than that.
- If the base is between zero and 1, then the function is decreasing.
- If the base is larger than 1, then the function is increasing.
In the given options there is only one function with a base larger than 1, which is the last option:
That is the correct option.

Answer:
AC = 32 units
Step-by-step explanation:
It looks like DE is half of AC, so to find the length of AC you would multiply the length of DE by 2.
DE = 5x + 6, so 2(5x + 6) = AC.
Distribute the 2 inside the parentheses.
Now make this value equal to the expression standing for AC, 12x + 8.
Subtract 10x from both sides of the equation.
Subtract 8 from both sides of the equation.
Divide both sides by 2 to solve for x.
Take this value of x and substitute it into the expression for the length of AC.
Multiply 12 and 2 together.
Add 24 and 8.
AC = 32 units
1:3:5
firstly u need to find out how much one will get so u will add all the ratios 1:3:5 and divide by 72k(72000) so you will get 8000
therefore 1 will get 8000
3 will get 8000 multiply by 3 =24000
5 will get 8000 multiply by 5 = 40000
do you understand......if you need any more help ...feel free!!!!
Answer:
408
Step-by-step explanation:
You would set up a proportion of 1/12 = 34/x. You would do the butterfly method and get 1x=408. Then divide 408 by 1 to get 408.
Answer:
1
Step-by-step explanation:
(1-x)/x=0
or, 1-x=0
or, -x=-1
or, x=1
