Answer: D

Step-by-step explanation:

A quadrilateral is a four sided figure, a rectangle is a parallelogram having two parallel sides. It is not a trapezoid —> quadrilateral with only one pair of parallel sides. this shape has two parallel sides.

the width of a rectangle is 1/4 it’s length. the perimeter of the rectangle is 600ft. what is the length, in feet, of the rectan

vovikov84 [41]

Answer:

let length be l and breadth 1/4×l

perimeter of the rectangle =600ft

2(l+1/4×l)=600ft

(4l+l)/4=600/2

5l=300×4

l=1200/5=240ft

Step-by-step explanation:

240ft is the length of a rectangular.

From the table below, determine whether the data shows an exponential function. Explain why or why not.

Answer:

b. No; the domain values are not at regular intervals although the range values have a common factor.

Step-by-step explanation:

The differences between x-values are ...

-1, -1, -1, -2 . . . . not a constant difference

The ratios of y-values are ...

2/8 = 0.5/2 = 0.125/0.5 = 0.25 . . . . a constant difference

The fact that the domain values do not have a common difference renders the common factor of the range values irrelevant. The relation is not exponential.

1.) Give five (5) examples of quadratic equations written in standard form. Identify the values of a, b, and c in each equation.

Kitty [74]

<h3>NUMBER 1:</h3>

1.) Give five (5) examples of quadratic equations written in standard form. Identify the values of a, b, and c in each equation.

a. 3 + x² = - 6x

Standard form: x² + 6x + 3 = 0

a, b, and c: a = 1, b = 6, c = - 3

b. x² - 3x = 18

Standard form: x² - 3x - 18 = 0

a, b, and c: a = 1, b = - 3, c = -18

c. 3 + 2x² = 6

Standard form: 2x² - 3 = 0

a, b, and c: a = 2, b = 0, c = -3

d. 3x + 2x² = 7

Standard form: 2x² + 3x - 7 = 0

a, b, and c: a = 2, b = 3, c = -6

e. x² + 8x = - 8

Standard form: x² + 8x + 8 = 0

a, b, and c: a = 1, b = 8, c = 8

<h3>NUMBER 2:</h3>

2.) Name three (3) objects or cite three (3) situations in real life where quadratic equations are illustrated. Formulate quadratic equations out of these objects or situations then describe each.

1 and 2.) A company is going to make frames as part of a new product they are launching. The frame will be cut out of piece of steel, and to keep the weight down, the final area should be 28 cm². The inside of the frame has to be cm by 6cm.

Area of steel before cutting :

= (11 + 2x) × (6 + 2x) cm²
= 66 + 22x + 12x + 4x²

Quadratic Equation = 4x² + 34x + 66

Area of steel after cutting out the 11 × 6 middle :

= 4x² + 34x + 66 - 66

Quadratic Equation = 4x² + 34

3.) A ball is thrown straight up, from 3m above the ground, with a velocity of 14 m/s.

Add them up and the height(h) at any time(t) is :

h = 3 + 14t - 5t²

Quadratic Equation = -5t² + 14t + 3 = 0
