sine's rule

$\tt \dfrac{A}{sin~a}=\dfrac{B}{sin~b}$

1. 27/sin 61 = BC sin 54

BC = 25

2. ∠A=180 -(17+111)=52

27/sin 52 = AB sin 17

AB = 10

3. AC/sin 65 = 27/sin 61

AC = 28

4. ∠C = 180 -(61+30)=89

24/sin 89=AC/sin 61

AC=21

A square has one of its sides increased by 7 inches and the other side decreased by 4 inches. Which of the following represents

Anna71 [15]

Answer:

Step-by-step explanation:

both the length and the width of a square is the same measurement.

so if both measured to "x" then that means one side increase +7.

so one side is x + 7

and the other side decreased -4

so the other side is x - 4

area of square = length x width or just one of the sides to the power of 2

so (x+7) * (x-4) = Area

x^2 + 3x - 21 = area

Answer:

A. 2,310 sq ft

Step-by-step explanation:

Rectengle below:

A = l × b
A = 74 × 15
A = 1,110ft

Rectangle Above:

A = l × b
A = 50 × 24
A = 1,200ft

Area of the Playground:

1,110ft + 1,200ft
1,310 sq ft (A)

Complete the steps to solve the polynomial equation x3 – 21x = –20. According to the rational root theorem, which number is a po

jeka94

Answer:

Zeroes : 1, 4 and -5.

Potential roots: $\pm 1, \pm 2, \pm 4, \pm 5, \pm 10, \pm 20$ .

Step-by-step explanation:

The given equation is

$x^3-21x=-20$

It can be written as

$x^3+0x^2-21x+20=0$

Splitting the middle terms, we get

$x^3-x^2+x^2-x-20x+20=0$

$x^2(x-1)+x(x-1)-20(x-1)=0$

$(x-1)(x^2+x-20)=0$

Splitting the middle terms, we get

$(x-1)(x^2+5x-4x-20)=0$

$(x-1)(x(x+5)-4(x+5))=0$

$(x-1)(x+5)(x-4)=0$

Using zero product property, we get

$x-1=0\Rightarrow x=1$

$x-4=0\Rightarrow x=4$

$x+5=0\Rightarrow x=-5$

Therefore, the zeroes of the equation are 1, 4 and -5.

According to rational root theorem, the potential root of the polynomial are

$x=\dfrac{\text{Factor of constant}}{\text{Factor of leading coefficient}}$

Constant = 20

Factors of constant ±1, ±2, ±4, ±5, ±10, ±20.

Leading coefficient= 1

Factors of leading coefficient ±1.

Therefore, the potential root of the polynomial are $\pm 1, \pm 2, \pm 4, \pm 5, \pm 10, \pm 20$ .
