Since 308 people can visit each day, and there's 8 shows each day, we just multiply 308 by 8.
308*8 = 2464 people.
Answer:
Step-by-step explanation:
Unless we set x^2 + 8x + 15 equal to zero, we don't have an equation to be solved. I will assume that the problem is actually x^2 + 8x + 15 = 0.
The coefficients of this quadratic are {1, 8, 15}, and so the "discriminant" b^2 - 4ac is (8)^2 - 4(1)(15), or 4. Because the discriminant is positive, we know that there are two real, unequal roots.
Continuing with the quadratic formula and knowing that the discriminant is 4, we get:
-8 ± √4 -8 ± 2
x = ---------------- = --------------- , or x = -2 ± 1: x = -3 and x = -5

Answer:
Width = 50ft
Length = 160ft
Step-by-step explanation:
Given parameter:
The perimeter of the flag is 420ft
Unknown:
Length of flag = ?
Width of flag = ?
Solution:
To solve this problem;
Perimeter of the flag is given as:
Perimeter = 2(Length + width)
Length =110 + Width
Now insert the parameters:
420 = 2(110 + Width + Width )
let w = width
420 = 2(110 + 2w)
420 = 220 + 4w
4w = 200
w = 50ft
Length = 110 + 50 = 160ft
Answer:
C = 34 degrees, A=8.6 feet
Step-by-step explanation:
Use sine law:
![sin^{-1} [12(\frac{sin122}{18})]= C](https://tex.z-dn.net/?f=sin%5E%7B-1%7D%20%5B12%28%5Cfrac%7Bsin122%7D%7B18%7D%29%5D%3D%20%20C)
C = 34 degrees
Now that you have the C and B degrees, solve for A degrees
180 - 34 - 122 = 24 degrees for angle A
Same way as above use sine law to find the side for a now:
A=8.6 feet
** Thing to note is that you can rearrage the sine formula to have either the legnth or the angle on top. It's pretty straightforward, find the angles you do have and then work from there. If sine law doesnt work with your example, use cosine law. and work backwards. Wish you luck.
