Make w = width

Since the length is 5 times the width, L = 5w

The formula for perimeter is
P = 2L + 2w

Since the perimeter is 48 and L = 5w
P = 2L + 2w
48 = 2(5w) + 2w
48 = 12w

Y=(x^2-6x+14) Labeling the vertex
zavuch27 [327]
I leaerned this neat trick
you don't need to convert to vertex form

where
y=ax^2+bx+c
the x value of the vertex is -b/2a
the y value is found by inserting the x value of the vertex into the equation


so

1x^2-6x+14
-b/2a=-(-6)/2(1)=6/2=3
plug that in
y=x^2-6x+14
y=3^2-6(3)+14
y=9-18+14
y=5

the vertex is (3,5)

Write the explicit equation for the sequence 5,8,11,14
mamaluj [8]
Consecutive terms differ by 3, so

a_n=a_{n-1}+3=a_{n-2}+2\times3=a_{n-3}+3\times3=\cdots=a_1+(n-1)\times3

Since the first term is a_1=5, the formula for the sequence is

a_n=5+3(n-1)=3n+2
