Answer:

Step-by-step explanation:

Here the coefficients of this quadratic are a = 1, b = 6 and c = 4.

-b

The axis of symmetry is x = -------- , which here is x = -6/2, or x = - 3.

Use the given quadratic to find the vertical coordinate of the vertex:

y = (-3)^2 + 6(-3) + 4 = 9 - 18 + 4 = y = -5.

The axis of symmetry is x = -3, and the vertex is (-3, -5).

Hey there, hope I can help!

$\frac{1}{4}\csc \left(2\pi t\right)\cot \left(2\pi t\right)dt\frac{1}{12}$

You add all of the numbers up each row and divide by how many there are so:
row one: if u add it all up it would be 10 then divide by how many there are

I don’t understand what to solve.

White raven [17]

Well since it gives you 2 gas stations it wants you to compare prices

Als gas station will be A
At-one will be B

since station A has $3.259/ gallon I assume
and B has $3.199/ gallon

just subtract them

so 3.259 -3.199 = 0.06

gas is less at station B noticeably costs less so thats your first answer

for the next one if you bought gallon of gas at the cheaper station you'd be saving $0.06/gallon since we got the difference from subtracting them.
