Answer:

Trinomial

Step-by-step explanation:

A trinomial consists of three terms. An algebraic term is the product of a numerical factor by one or more literal variables. In each algebraic term the numerical coefficient (which includes the sign and mathematical constants) and the literal part (which includes variables) are distinguished.

olga nikolaevna [1]

Answer:

10.54 kg

Step-by-step explanation:

Given that :

Half of blueberries is served with breakfast

The remaining 5270g is served with dinner

How many kilograms of blueberries did the science camp start with :

Total grams of blue berries :

(Grams served at breakfast + grams served at dinner)

Let total blueberries = x

x/2 + 5270 = x

(x + 10540) /2 = x

x + 10540 = 2x

10540 = 2x - x

x = 10540 grams

Amount of kilograms science camp started with = (10540) / 1000 = 10.54 kg

Dana has 800 yards of fencing to enclose a rectangular area. Find the dimensions of the rectangle that maximize the enclosed are
grin007 [14]

Answer:

Perimeter of rectangle states that total distance around the outside, which can be found by adding together the length of each side.

As per the given statement, Dana has 800 yards of fencing to enclose a rectangular area.

Therefore, perimeter of rectangle = 800 yards.

Perimeter(P) of rectangle is given by :

P = 2(x+y) where x is the length and y is the width of the rectangles respectively.

Then,

2(x+y) = 800

Divide both sides by 2 we get;

x+y =400

or

y = 400 -x            .....[1]

We know, the area(A) of rectangle is given by

A = xy                   .....[2]

Substitute equation [1] into [2] we get;l

A = x(400-x)

using distributive property a\cdot (b+c) = a\cdot b+ a\cdot c

A = 400x -x^2            

or

A =-x^2+400x    ......[3]

To maximize the enclosed area.

For a quadratic function in standard form y =ax^2+bx+c , the axis of symmetry is a vertical line given by;  

x = -\frac{b}{2a}

Then; we have from equation [3]

a = -1 and b = 400

By axis of symmetry;

x = -\frac{b}{2a} = -\frac{400}{2 \cdot -1} =\frac{400}{2} = 200

Substitute in equation [1] to solve for y:

y = 400 - 200 = 200

The dimensions of the rectangle that maximize enclosed area are:

x = 200 units and y = 200 units.

Maximum area = 200 \times 200 = 40,000 square units.

We can say that maximum area of rectangle will always be a square
