Answer:
f(6) = -14
Step-by-step explanation:
x = -6
f(x) = x^2/3 - 2
f(-6) = (-6)^2/3 -2 Replace x with the given number
= -36/3 - 2 Simplify -6 to the power of 2
= - 12 - 2 Divide -36 by 3
f(6) = - 14 Subtract -2 from -12
34/32 can also be written as 1.0625 or 1 & 1/16.

Depends on how much you offer for an answer. Offer 10 points and you'll be able to ask 400 questions. Offer 20 points, I think around 200 questions.
Y = -(1/2)(x-2)² +8
Re write it in standard form:
(y-8) = -1/2(x-2)² ↔ (y-k) = a(x-h)²
This parabola open downward (a = -1/2 <0), with a maximum shown in vertex
The vertex is (h , k) → Vertex(2 , 8)
focus(h, k +c )
a = 1/4c → -1/2 = 1/4c → c = -1/2, hence focus(2, 8-1/2) →focus(2,15/2)
Latus rectum: y-value = 15/2
Replace in the equation y with 15/2→→15/2 = -1/2(x-2)² + 8
Or -1/2(x-2)² +8 -15/2 = 0
Solving this quadratic equation gives x' = 3 and x" = 2, then
Latus rectum = 5
Answer:
t = w/3-11/3
Step-by-step explanation:
w = 3t + 11
3t = w-11
t = 1/3(w-11
t = w/3-11/3
