Answer:
a₁ = 1
r = 3
Step-by-step explanation:
Since it’s a geometric series then
a₁ = 1 ( because 1 is the first term of the series)
3/1 = 9/3 = 27/9 = 81/27 = 3 then r=3.

Answer:
is a function that reverse another function if de function apply to an input x gives a result of a y den applying its inverse function g to y gives de result of x nd opposite eg f (x )=y nd if g (y )=x
Answer:
vertex: (2,-18)
Step-by-step explanation:
y = ax² + bx + c
(-1,0) : a - b + c = 0 ...(1)
(5,0) : 25a +5b +c = 0 ...(2)
(0,-10): 0a + 0b + c = -10 c=-10
(1) x5: 5a - 5b + 5c = 0 ...(3)
(2)+(3): 30a + 6c = 0 30a = -6c = 60 a = 2
(1): 2 - b -10 = 0 b = -8
Equation: y = 2x² - 8x -10 = 2 (x² -4x +4) - 18 = 2(x-2)² -18
equation: y = a(x-h)²+k (h,k): vertex
vertex: (2,-18)
$86.62 would be the total after 15% tax.
Answer:
Costo unitario= $3
Step-by-step explanation:
Dada la siguiente información:
Entrada= $4.5
Cantidad de entradas de más= 2
Cantidad de amigos que pagan= 3
<u>Primero debemos calcular el total a pagas de más:</u>
Total a pagar de más= 2*4.5= $9
<u>Ahora, cuánto debe pagar cada uno:</u>
<u />
Costo unitario= costo total / cantidad de personas
Costo unitario= 9/3
Costo unitario= $3
