Answer:

pi/12 rads

Step-by-step explanation:

We know -pi/12 goes clockwise. Since it goes down pi/12 radians, the answer is simply pi/12 because when it connects to the x axis, it makes an ACUTE angle (which is the reference angle, and is always positive) of pi/12 rads.

Juan is thinking of two numbers. He says that 3 times the first number minus the second number is 118. In addition, two times th
Ne4ueva [31]
We will call the first number n, and the second number x.

3n-x=118

2n+x=147

Now, solve one of the equations for x.

x=147-2n

Then, substitute this into the other formula for x. 

3n-(147-2n)=118

Next, solve for n:

3n-147+2n=118
5n=265
n=53
^^^That's your first number.

Lastly, plug in 53 for n into either equation to solve for x.

2(53)+x=147
106+x=147
x=41
^^^This is your second number.

Y = f(x) = 3<br> Find f(x) when x = 0.<br> Enter the correct answer.
dalvyx [7]

Answer:

3

Step-by-step explanation:

Because f(x) = 3, any value of x will make f(x) = 3. So when x = 0, f(x) = 3.

The functions f(x) and g(x) in the table below show Kim's and Ben's savings respectively, in dollars, after x days. Some values
frutty [35]

The table can be filled in as follows:

\begin{array}{r|cccc}x(days)&1&2&3&4\\g(x)=3^x&3&9&27&81\\f(x)=3x+5&8&11&14&17\end{array}

After 3 days, Kim's savings already exceeds Ben's, and is increasing at a faster rate. The appropriate descriptor is ...

... Kim will save more than Ben

_____

An exponential function increases faster than any polynomial function. (A linear function is a polynomial function.)

If Kim keeps up her savings for 28 days, her account balance will exceed the US Gross National Product of more than $20 trilliion. (Exponential functions tend to increase very rapidly!) Meanwhile, Ben's savings will be $89 on day 28.

_____

Please note the discrepancy in the problem statement. The verbiage says "days", but the table shows "years".
