The line of symmetry.
It divides the parabola into to halves that are exactly the same.
If a is the number of events, then a = 1. Plugging in 1 for a in the equation
, you get
.
Total cost is $9.
Answer:
Area = 27 cm²
Step-by-step explanation:
let L be the length of the rectangle
w the width
P the perimeter
A the area
<u>Formulas</u> :
P = 2×(L + w)
A = L × w
<u>We are Given</u> :
L = 3w
P = 2×(L + w)
⇔ 24 = 2×(3w + w)
⇔ 24 = 2×4w
⇔ 24 = 8w
⇔ w = 24/8 = 3
Then
L = 3w = 3×3 = 9
We obtain L = 9 and w = 3.
Then
A = L × w
= 9 × 3
= 27
Well, if we look at a calculator and ask, what is 8% of 3000$ we get the answer of 240 dollars.
3000 - 8% = 2760 therefor we know it removes 240 dollars. So the commission is 240 dollars.
