Answer:

\large\boxed{\theta=k\pi,\ k\in\mathbb{Z}}

Step-by-step explanation:

\sec\thets\cdot\sin\theta=0\iff \sec\theta=0\ \vee\ \sin\theta=0\\\\\sec\theta\neq0\ \text{for any value of}\ \theta\\\\\sin\theta=0\Rightarrow\theta=k\pi\ \text{where}\ k\in\mathbb{Z}

Proving That All Circles Are Similar
Nitella [24]

Answer:

Figures can be proven similar if one, or more, similarity transformations (reflections, translations, rotations, dilations) can be found that map one figure onto another. In our attempt to prove all circles are similar, a translation and a scale factor (from a dilation) will be found to map one circle onto another.

Margot is trying to decide between cable and satellite TV. Cable has a package of $49.99 a month for the basic package, plus $9.
VashaNatasha [74]
The cost of cable (c) in terms of months (m) is
  c = (49.99 +9.95 +9.95 -10.00)m
  c = 59.89m

The cost of satellite TV (s) in terms of months is
  s = 125.00 +49.95m

The difference in price is ...
  s - c = (125 +49.95m) -(59.89m)
  s - c = 125 -9.94m

At 12 months, the difference in price is
  s - c = 125 -9.94*12 = 5.72
This number is positive, which means ...
  the Cable company will save Margot money over a 12-month period.

At 24 months, the difference in price is
  s - c = 125 -9.94*24 = -113.56
This number is negative, which means ...
  the Satellite TV company will save Margot money over a 24-month period.


_____
A graph of the costs shows a cross-over at 12.5 months. Until then, the Cable provider is less expensive. Over terms longer than that, the Satellite TV provider is less expensive.

X+4y=-4, x+10y=-16, solve using systems of equations, elimination
lora16 [44]

Answer:

x = 4

y = -2

Step-by-step explanation:

x + 10y = -16

-x -4y = 4 <-- ( multiplied x+4y=-4 with -1 so the x's cancel)

6y = -12

y = -2

put -2 back in the equation to get x

x + 10y = -16

x -20 = -16

x = 4
