F(x) = (x + 5)2(x - 9)(x + 1)

Answer:

x = 5 and ( 5 , − 9 )

Explanation:

The equation of a parabola in vertex form is.

2 2 y = a ( x − h ) 2 + k 2 2

Where ( h , k ) are the coordinates of the vertex and a is a multiplier

f ( x ) = ( x − 5 ) 2 − 9 is in this form

with ( h , k ) = ( 5 , − 9 )

⇒ vertex = ( 5 , − 9 )

the axis of symmetry passes through the vertex is vertical with equation

x = 5 ← axis of symmetry graph{(y-x^2+10x-16)(y-1000x+5000)=0 [-20, 20, -10, 10]}

Two pony express riders each rode part of a 176 mile trip. Each rider rode the same number of miles. They changed horses every 1

atroni [7]

Answer:

Total number of horses used = 16

Step-by-step explanation:

Two pony express riders each rode part of a 176 mile trip. Each rider rode the same number of miles.

$\texttt{Total mile rode by each pony express rider = }\frac{176}{2}=88miles$

They changed horses every 11 miles.

$\texttt{Number of horses used by each pony express rider = }\frac{88}{11}=8$

Total number of horses = Number of horses used by each pony express rider x Number of pony express rider

Total number of horses used = 8 x 2 = 16

Total number of horses used = 16
