First row: subtitute p with 2
2(13 - p)
= 2(13 - 2)
= 2(11)
= 22

Second row: subtitute p with 3
2(13 - p)
= 2(13 - 3)
= 2(10)
= 20

Third row: subtitute p with 4
2(13 - p)
= 2(13 - 4)
= 2(9)
= 18

The answers are:
22
20
18

A farmer owns a total of 10 acres of land. The land is separated into 43 equally sized sections. How many acres are in each sect
Pepsi [2]

Answer:

\frac{10}{43} acres

Step-by-step explanation:

Divide 10 by 43:

10/43

In simplest form as a fraction, this is \frac{10}{43}

So, each section would have \frac{10}{43} acres

Sketch the graph of y=x^2-4x+3
NISA [10]

Answer:

see attached graph

Step-by-step explanation:

Given equation:  y=x^2-4x+3

Standard form of a quadratic equation: y=ax^2+bx+c

where c is the y-intercept

If a > 0 then the parabola opens upwards.

If a < 0 then the parabola opens downwards.

Therefore, the y-intercept of the graph is (0, 3)

To find the x-intercepts, factor the equation:

       y=x^2-4x+3

\implies y=x^2-x-3x+3

\implies y=x(x-1)-3(x-1)

\implies y=(x-3)(x-1)

Therefore, the x-intercepts of the graph are (3, 0) and (1, 0)

To determine the vertex, differentiate the equation:

\implies \dfrac{dy}{dx}=2x-4

Set to zero and solve for x:

2x-4=0 \implies x=2

Substitute x=2 into the original equation and solve for y:

\implies y=(2)^2-4(2)+3=-1

Therefore, the vertex (or turning point) is at (2, -1)

PLEASEEEEEEEEEE HELPPPPPPPPPPPPPPPPPPPPPPPPPPPP
Arisa [49]

Answer:

  • A = 18.85ft^2
  • 114cm^2
  • 835.578 in^2
  • 24o yd^2

Step-by-step explanation: I hope it helps :)

1.

Surface\: area=\:2\pi rh+2\pi r^2\\h = 2ft\\diameter = 2ft\\Radius = d/2=2/2=1ft\\\\A=( 2\times 3.141\times1\times2)+(2\times 3.141 \times 1^2)\\A = (12.564)+(6.282)\\A = 18.846\\A = 18.85ft^2

2.

Area \:of\: square = A=a^2\\A = 3^2\\A=9\\Area\:of \:one \:rectangle\: = (l\times b)\\ A = (8\times 3)\\A = 24cm^2\\\\A = 2(Area\: of\: square)+2(Area\: of \:rectangle)\\A = 2(9)+4(24)\\A = 18+96\\A =114cm^2

3.

Area \: of\: base=?\\ r = 7\:in\\h = 12\:in\\A = \pi \times r^2\\A = 3.141 \times 7^2\\A = 153.909\\\\Height \: of \:the \:cylinder = 12\:inches\\Circumference = 2\pi \times r\\C= 2 \times 3.141 \times 7\\ C =43.98\\\\S.A= 2B+Ch\\S.A = 2(153.909)+43.98(12)\\S.A = 307.818+527.76\\S.A =835.578

4.

Perimeter = a+b+c\\P = 10+8+6\\P = 24\\S.A =2B+Ph\\S.A = 2(24)+24(8)\\S.A =48+192\\S.A = 240\:yd^2
