Answer:
3rd answer f(x) = 3(x-8)(x+2)
Step-by-step explanation:
The x-intercepts are the points at which the parabola intersects the x-axis.
Function y = a(x - r₁)(x - r₂) is in factored form, where r₁ and r₂ are x-intercepts so if r₁ = 8 and r₂ = -2 then
y = a (x-8)(x-(-2))=a(x-8)(x+2)
For y intercept plug in (0,-48) in equation and calculate a:
-48 = a (0-8)(0+2)
-48 = a(-8)(+2)
-48 = -16a divide by -16
a = 3
Function is y = 3(x-8)(x+2)
Answer:
For every 2 quarts of water, ¹/₂ cup of vinegar is used.
⇒ To find the amount of vinegar, divide the number of quarts by 4.
⇒ To find the number of quarts, multiply the amount of vinegar by 4.
4 qt water = 4 ÷ 4 = 1 cup vinegar
1¹/₂ cups vinegar = 1¹/₂ x 4 = 6 qt water
8 qt water = 8 ÷ 4 = 2 cup vinegar
Plot the points on the graph (see second attached image).
Draw a line through the points.
Find 3 along the x-axis and trace up to the line. Trace along to the y-axis.
Therefore, Gavin would need to use 12 quarts of water with 3 cups of vinegar.
The percent makeup they are charging is 25%.
It would cost somehow less than $1000 and you would know that because 347 students is a large number, but since it hold 44 students in each bus, it’ll take not to long to get to 347. So since each bus is $95, it would at least reach to 700+
