Answer:
x= - 16
Step-by-step explanation:
substitute y=0 then multuply both sides move the variable to the left and change the sign.
Answer:
395.85
Step-by-step explanation:
If the diameter is 12, then the radius must be 6. Following the formula of pi: 2 * pi * radius, our result is 37.7. 37.7 * 10.50 is 395.85
I really hope this helps. My memory of circles and pi isn't the best.
Answer:
Step 4, x = 3
Step-by-step explanation:
Step 4 was wrong, instead of 6x = 6, it should be 6x = 18. They shoudl've added 6 to both sides instead of subtracting 6 as ur trying to cancel out the 6 on the left side of the equation. So:
6x = 18
x = 3

<h2>
Step-by-step explanation:</h2>
To solve this problem, we need to start with the parent function of the exponential function, which is 
, where 
is the base. In our problem, 
, so our parent function here is 
. Then, we need to perform some transformations to our parent function. Thus:
1. Vertical shrink:
A vertical shrink is a nonrigid transformation because the graph of the function get a distortion in the shape, so this transformation is as follows:
where 
in this problem equals 0.25 because:
2. Vertical shift:
The graph of the function 
get a vertical shift given by:
So the graph is shifted 3 units up. So the result is the graph shown above.
