Since you were able to type that negative, I will assume that
f(x)=-x^2+3x+8

the vertex is where the graph changes from increasing to decreasing or vice verca

find theh vertex
-b/2a is x coordinate of vertex where
f(x)=ax^2+bx+c


a=-1
b=3
-3/2(-1)=-3/-2=3/2

we see that the leading coeficient (a) is negative so the graph opens down
it increases then decreases at the vertex

so from negative infinity to 3/2 is interval

A contractor is installing tiles on a floor that measures 132 x 216 inches. If each tile measures 4 x 4 inches, how many tiles w
Kay [80]

Answer:

1782 tiles

Step-by-step explanation:

Given that:

Dimension fo floor = 132 x 216 inches

Area of floor = 132 * 216 = 28512 in²

Dimension of tiles = 4 * 4 inches

Area of tiles = 4 * 4 = 16 in²

Number of tiles needed to cover floor :

Area of floor / Area of tiles

28512 in² / 16 in²

= 1782 tiles

The perimeter of a regular pentagon is represented by the expression 35d-25. Daryl correctly wrote expression to represent the o
Triss [41]

Answer:

Each one of the sides is equal to 7d-5

Step-by-step explanation:

A regular pentagon has 5 sides of equal length.

The perimeter of a regular pentagon is given by

P = 5s where s is the side length

35d -25 = 5s

Divide each side by 5

(35d-25)/5 = 5s/5

7d-5 =s

Each one of the sides is equal to 7d-5

dalvyx [7]
1. You could break them up:
10+30+20+10=70
6+5+4+4=19
70+19=89

2. Separate to groups:
16+35=51
24+14=38
51+38=89
