Answer:

Step-by-step explanation:
Choices aren't given, so i will solve this equation and find the first positive x-intercept angle.
First, x-intercept means the x-cutting point of the graph. This occurs when y = 0. So we will solve the equation for x. Shown below:

Inverse Cotangent (ArcCot) of 0 is at
, so we can now solve for x:

So, the x-intercept is at x = pi/6
Both of the above choices would be correct or true as regardless did reflecting across the x and or y axis first. You would then need to reflect it across the other axis to get to that particular image.
The last option would be false, because if you reflected it across the y axis and move down it will be upright and not inverted.

Answer:
increase
Step-by-step explanation:
Your cost function appears to be an exponential function of the form ...
c(x) = (initial cost)·(growth factor)^x
When the growth factor (1.03) is greater than 1, it means the exponential function is increasing with x (time).
The cost function increases with time.
Answer:
1:2
Step-by-step explanation:
There are 18 nickles so that number is 18. When added together, there are 36 total coins. Since it states nickle to all coins, we replace <em>to</em> with a colon and replace the words with the related numbers.
18:36
like a fraction, ratios can be simplified. 18 is half of 36 so the ratio would go to 1:2. This means that 1 in every 2 coins is a nickle.
