Answer:

see below

Step-by-step explanation:

f(x) = 5x^3 +1, g(x) = – 2x^2, and h(x) = - 4x^2 – 2x +5

f(-8) = 5(-8)^3 +1 = 5 *(-512) +1 =-2560+1 =-2559

g( -6) = -2 ( -6) ^2 = -2 ( 36) = -72

h(9) = -4( 9)^2 -2(9) +5 = -4 ( 81) -18+5 = -324-18+5=-337

The graph of r = -10 cos θ has which of the following characteristics?

Ronch [10]

Step-by-step explanation:

If we convert

$r = - 10 \cos(x)$

to a Cartesian equation,

${r}^{2} = - 10 r \: \cos(x)$

${x}^{2} + {y}^{2} = - 10x$

${x}^{2} + 10x + {y}^{2} = 0$

${x}^{2} + 10x + 25 + {y}^{2} = 25$

$(x + 5) {}^{2} + {y}^{2} = 25$

So we have a circle with center (-5,0), with a diameter of 10.

If the measures of five interior angles of a hexagon are 133 , 111 , 92 , 153 , and 109 , what is the measure of the other inter

Burka [1]

The sum of the interior angles of a hexagon is equal

$6\cdot\left(180^o-\dfrac{360^o}{6}\right)=6\cdot(180^o-60^o)=6\cdot120^o=720^o$

Calculatle the measure of the other interior angle:

$720^o-(133^o+111^o+92^o+153^o+109^o)=720^o-598^o=122^o$

Answer: 122°
