Complete the square to transform the expression x^2+4x 2 into the form a(x − h)2 + k.

faust18 [17]

Answer:

$(x+2)^2-2$

Step-by-step explanation:

we have the expression

$x^2+4x+2$

Convert to vertex form

$a(x-h)^2+k$

where

a is the leading coefficient

(h,k) is the vertex

Complete the square

$(x^2+4x+2^2)+2-2^2$

$(x^2+4x+2^2)-2$

Rewrite as perfect squares

$(x+2)^2-2$

The coefficient a =1

The vertex is the point (-2,-2)

An amusement park is open for 15 hours a day, 7 days a week

sertanlavr [38]

Answer:

The domains are;

0 < x < 3 for f(x) = 15

3 ≤ x ≤ 7 for f(x) = 22

7 < x ≤ 15 for f(x) = 30

Step-by-step explanation:

The duration the amusement park is opened, t = 15 hours

The number of days the amusement is opened = 7 days a week

The prices for the admission are;

x < 3 hours = $15

3 ≤ x ≤ 7 hours = $22

x > 7 hours = $30

The functions are;

f(x) = 15 when x < 3; The domain = 0 < x < 3

f(x) = 22 when 3 ≤ x ≤ 7; The domain = 3 ≤ x ≤ 7

f(x) = 30 when x > 7; The domain = 7 < x ≤ 15.
