Answer:
see the corrected graph below
Step-by-step explanation:
For starters, the solid and open dots need to swap places. The "or equal to" is not present for the middle segment, only the end segments.
Then the function for x ≥ 1 needs to be properly graphed. it is only defined on the interval 1 ≤ x < 3, so should will extend beyond x=3.
Answer:
The answer is y = 4x - 8.
Step-by-step explanation:
☆Remember:
☆Slope-intercept:
---
☆We need to find the slope first. So just plug in according to the slope formula!
---
☆Now we need to find the y-intercept. We are going to plug in the slope and a set of coordinates to find the y-intercept.
---
☆Now all we need to do is plug in and we are done!

Answer:
The length of the actual wall is 405 inches or 33.75 feet
If you're using a graphing calculator, make sure you're in DEG mode (not RAD). There probably is no button for the secant function, but remember that secant is defined as the reciprocal of cosine:
So on your calculator, you'd type
1/cos(19)
and you should get about 1.0576.
