If the planes are parallel to one another then they will never intersect (assuming they are distinct planes as the question states).
Otherwise they will intersect along a single line.
Therefore the answer is NEVER - they can never intersect in a pair of lines.
Answer:
Step-by-step explanation:
You can solve this equation with the quadratic formula which is:
All you need to do is rearrange the equation (add to both sides and then multiply both sides by 2) to get:
From this new equation, we can easily see that a = 2, b = -5, and c = 11 AND you don't have to work with as many fractions. Substitute the values for a, b, and c into the quadratic formula to get:
That simplifies to:
Which simplifies even further to:
Which gets you:
P.S. The plus-minus sign wasn't working for me, so I had to just write, "+or-". I hope that didn't make it too confusing for you.
P.P.S. Hope this helps :) Don't forget to mark Brainliest if it did.
Answer:
$6.4
Step-by-step explanation:
You just do 32 × .2 to give you the discount of 6.4
You multiple by .2 because 20% as a decimal is .2 ( you do 20% divided by 100 to give you .2)
What will the radius of your cake be?
This is a problem of geometry. Given that the cake is circular, the greater the cake the greater the radius of it. So, as shown in the figure 1, the radius will be the distance from the center to any extreme point of the circle.
How many slices will you be able to cut?
The total area of a circle is given by:
We need to fin how many slices will be cut, so let's calculate the area of the circular sector which can be obtained simply applying rule of three, so:
Let's name n the number of slices, if we divide the total area by n this result, each area must equal, then:
Finally, we will be able to cut:
Slices
Answer:
The answer is 7.5 tax rate
