Y = x^2 + 5x + 3
y = √(2x + 5)
Using a calculator, put equation 1 in y(sub1) and equation 2 in y(sub2).
Graph the equations and fin the point of intersection.
If using a TI 83/84 calculator, to find the point of intersection: 2nd CALC #5.
LETTER B
Answer:
29: A
30: $7.50
31: number of dots in total:
1) 0 dots
2) 1 dot
3) 1 dot
4) 3 dots
5) 1 dot
6) 1 dot
7) 1 dot
8) 0 dots
Step-by-step explanation:
So hmm notice the picture below
thus, the perimeter of the gutter is just w + w + l, or 2w +l
thus

take the derivative of A(w), zero it out, check any critical points in the interval of (0, 22), for a maxima
recall, the aluminum sheet is just 22inches long, thus, whatever the "depth" or "w" is, has to be more than 0, and less than 22
plug in those two number for x and y
A. 35 Seconds
B. 102 Times
Hope This Helped.
