That equation can represent the relationship among the image distance,
object distance, and focal length of a lens.
It could describe the effective resistance of two resistors in parallel, the
effective inductance of two coils in parallel, or the effective capacitance
of two capacitors in series.
Thanks for sharing it. Now, did you have a question to ask ?
Answer:
<h2>3,600 m²</h2>
Step-by-step explanation:
The formula of a surface area of a sphere:
<em>R</em><em> - radius</em>
<em />
We have <em>R = 30m</em>.
Substitute:
Answer:
1.) FI, AD, FA, DI. (Neither of them are parallel or right angles.)
2.) 95 (Same angle just upside down so it'd be the same size.)
The discount price will be 0.8X dollars.
Step-by-step explanation:
Given,
Price of an item = X dollars
Discount = 20%
Amount of discount = 20% of Price of item
Amount of discount =
Price of item after discount = Price of item - Amount of discount
Price of item after discount = X-0.2X = 0.8X dollars
The discount price will be 0.8X dollars.

You have a right triangle situation here, and what you are looking for is the length of the hypotenuse. The leg perpendicular to the ground is 100, and the base angle that is NOT the right angle, is 65. So your equation is set up like this: sin 65 = 100/x. Rearrange that a bit to get x alone: x = 100/ sin 65. Make sure your calculator is in degree mode and solve for x. x = 110.34 feet of string.
