Find an ordered triple that represents 65 = (2, 6, 8) and Ž = (1, -2, 6).

Igoryamba

Answer:

< 40, 28, 72 >

Step-by-step explanation:

Given

y = < 2, 6, 8 > and z = < 7, - 2, 6 > , then

6y + 4z

= 6 < 2, 6, 8 > + 4 < 7, - 2, 6 >

Multiply each component by the scalar quantity

= < 6(2), 6(6), 6(8) > + < 4(7), 4(- 2), 4(6) >

= < 12, 36, 48 > + < 28, - 8, 24 >

Add corresponding components

= < 12 + 28, 36 - 8, 48 + 24 >

= < 40, 28, 72 >

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.
