Answer:

d = C - 2/3

Step-by-step explanation:

Subtract 2/3 from both sides of the equation:

C = d + 2/3

-2/3 -2/3

Find the general form, Ax2+Ay2+Dx+Ey+F=0, by identifying the coefficients A,D,E,&F center:(0,1); r=1 (x-0)2+(y-1)2=1 x2+y2-2

siniylev [52]

Answer:

The value of A is 1, D is 0, E is -2 and F is 0.

Step-by-step explanation:

The given equation is

$Ax^2+Ay^2+Dx+Ey+F=0$ ...(1)

The standard form of the circle is

$(x-h)^2+(y-k)^2=r^2$

Where, (h,k) is the center of the circle and r is the radius.

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

$x^2+y^2-2y+1-1=0$

$x^2+y^2-2y=0$

It can be written as

$x^2+y^2+0x-2y+0=0$ ....(2)

On comparing (1) and (2) we get.

$A=1$

$D=0$

$E=-2$

$F=0$

Therefore the value of A is 1, D is 0, E is -2 and F is 0.

Erica is making feathered caps for her school play. Each cap must have 3 feathers. Write an equation that represents the number

FrozenT [24]

Answer:

$f=3c$

Step-by-step explanation:

Given:

Number of feathers = $f$

Number of caps = $c$

Number of feathers in each cap = 3

Now, solving by setting up a proportion.

1 cap has 3 feathers. 'c' caps has 'f' feathers.

This gives,

$\dfrac{1}{3}=\dfrac{c}{f}$

Solving by cross multiplication, we get:

$1\times f=3\times c\\\\f=3c$

Therefore, the equation representing the number of feathers 'f' Erica needs to make 'c' caps is given as:

$f=3c$
