Answer:

625 metres

Step-by-step explanation:

Given the area function expressed as a(w)=-(w-25)^2+625.

The maximum area occurs at when da/dw = 0

da/dw = -2(w-25)

0 = -2(w-25)

-2(w-25) = 0

w - 25  = 0

w = 25

Substitute w = 25 into the modeled equation;

Recall a(w)=-(w-25)^2+625.

a(25)=-(25-25)^2+625

a(25) = 0+625

a(25) = 625

Hence the maximum area possible is 625 metres

Leah gets to paint her room since she bought a new bedspread set. Two gallons of paint covers 800 square feet. How many gallons
loris [4]

Answer:

3 gallons

Step-by-step explanation:

If two gallons of paint covers 800 square feet, 'x' gallons of paints will cover 1200square feet room where x is the number of gallons needed to paint the 1200 square feet room.

Mathematically,

2 gallons = 800sq.ft

x gallons = 1,200sq.ft

x × 800 = 2 × 1200

x = 2 × 1200/800

x = 3 gallons

Therefore Leah will need 3gallons of paint for 1200sq.ft room

A 2-column table with 8 rows. The first column is labeled x with entries negative 3, negative 2, negative 1, 0, 1, 2, 3, 4. The
mrs_skeptik [129]

Answer:

Option B.

Step-by-step explanation:

The given table of values is

x         f(x)

-3       -2

-2        0

-1         2

0         2

1          0

2        -8

3        -10

4        -20

We need to find the interval for which the function f(x) is positive.

From the given table it is clear that the value of function f(x) is negative before -2 and after 1.

The function positive between x=-2 and x=1. So, we can conclude that the function f(x) is positive for the interval (-2,1).

Therefore, he correct option is B.

Rainbow [258]

Answer:

10.25

Step-by-step explanation:

Using the pythagorean theorem

13^2 = 8^2 + (ML)^2

169 = 64 + (ML)^2

Subtract 64 from both sides

105 = (ML)^2

Take the square root of both sides

10.25 = ML
