5 0

Answer:

-27

Step-by-step explanation:

Given: f(x)= -x^2+10x-16, g(x)= |11-2x^2|

f(9)= -(9)^2+10(9)-16

= -7

g(-5)= |11-2(-5)^2|

=39

Solve: 2[f(9)]-1/3[g(-5)]

= 2[(-7)] - 1/3[39]

= -27

(-3, 3), (1, -5)
x1  y1  x2 y2

\sf~m=\dfrac{-5-3}{1-(-3)}

Subtract:

\sf~m=\dfrac{-8}{4}

Divide:

A circle passes through the vertices of a square of side 20cm.Find the radius of the circle.
algol13

Answer:

14,1 cm

Step-by-step explanation:

If a circle passes through the vertices of a square then the diagonal of a square is a circle diameter.

We use Pytagoras Theorem to find out the length (L)  of the diagonal given that:

L²  =  (20)²  +  (20)²

L²  = 2* (20)²

L  = √2 * 20

L  = 1,4142* 20

L = 28,28 cm

L diagonal in the square is a diameter of the circle then radius of a circle is:

r = L/2   ⇒   r  = 28,28 /2   ⇒   r = 14,14 cm
