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)

Answer:

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

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

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

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

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

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