<span>(x-h)^2 + (y-k)^2 = r^2
</span><span>where r is the radius of the circle, </span>
<span>and h,k are the coordinates of its center;
( x - 8 )^2 + ( y - ( - 2 ) )^2 = 1 ^2 ;
r = 1 ;
h = 8 ; k = - 2.</span>
4:32 is the same as 2:16 and 12:96. A ratio is the same as a fraction, so you can reduce them the same way. 4/2 = 2, 32/2 = 16. 2*6 = 12, 16*6 = 96.
Can you do the second one on your own now?
Answer:
A = 73.33
B = 53.33
C = 53.33
Step-by-step explanation:
Since they are in a triangle, the sum of the three angles = 180
A + B + C = 180 ••••••(i)
Since B and C are congruent, it means that they are equal;
hence B = C ••••••(ii)
We can rewrite equation i as;
A + B + B = 180
A + 2B = 180 ••••••(iii)
Lastly;
B = A -20 •••••(iv)
Substitute iv into iii
A + 2(A -20) = 180
A + 2A -40 = 180
3A = 180 + 40
3A = 220
A = 220/3 = 73.33
But B = C = A -20 = 73.33 -20 = 53.33
Answer:
If g(t) = t^2 - 5t, then G = t - 5
If f(t) = 2t + 4, then F = 2( t + 2) / t (over t)
If (g * f)(5), then 5gf
