What do the triangles look like
Answer:
2010
Step-by-step explanation:
Center of the circle: C=(3,8)=(h,k)→h=3, k=8
Radius of the circle: r=5
Standard form of the equation for the circle:
(x-h)^2+(y-k)^2=r^2
(x-3)^2+(y-8)^2=5^2
(x-3)^2+(y-8)^2=25
General for of the equation for the circle:
(x)^2-2(x)(3)+(3)^2+(y)^2-2(y)(8)+(8)^2=25
x^2-6x+9+y^2-16y+64=25
x^2+y^2-6x-16y+73=25
x^2+y^2-6x-16y+73-25=25-25
x^2+y^2-6x-16y+48=0
Answer: The general form of the equation for the circle is:
x^2+y^2-6x-16y+48=0
Step-by-step explanation:
the question is z²=1
taking square root on both sides
√z² = √1
the square root and the square cancel out each other
it gives
z=±1
that means either z=+1 or z=-1
so the solutions are 1 and -1
Answer:
60.07%
Step-by-step explanation:
Decrease: 16.78 - 6.70 = 10.08
% decrease:
10.08/16.78 × 100 = 60.07151371%
