Answer:

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k ) = (2, 3 ) and r = 6, thus

(x - 2)² + (y - 3)² = 6², that is

(x - 2)² + (y - 3)² = 36 → D

trapecia [35]

Answer:

$F^{'}=(250\sqrt{3},250 })$

Step-by-step explanation:

We have F´ =500 and $\alpha$ =30º, so x and y components:

F´ = $(F_{x} , F_{y})$ this is

$F_{x} = F^{'} *Cos\alpha$

$F_{y} = F^{'} *Sin\alpha$

$F_{x} = F`*Cos\alpha =500*Cos30=500*\frac{\sqrt{3} }{2} =250\sqrt{3}$

$F_{y}=F*Sin\alpha =500*Sin30=500*\frac{1}{2}=250$ ;

Finally

F' = $(250\sqrt{3} , 250)$

Kevin and Brittany write an equation to represent the following relationship, and both students solve their equation. Who found

Vadim26 [7]

Kevin, because the problem says the difference of a number (x) and 20, and since 20 is mentioned second, it would therefore be the second number in the problem

How do you solve -9( -4r + 6s ) + 3s - 7(6s - 2r)

slavikrds [6]

Answer: 2.1 Pull out like factors :

6s - 2r = -2 • (r - 3s)

Equation at the end of step

((0-(9•(6s-4r)))+3s)--14•(r-3s)

Pulling out like terms

4.1 Pull out like factors : 6s - 4r = -2 • (2r - 3s)

Equation at the end of step

((0--18•(2r-3s))+3s)--14•(r-3s)

Final result :
