A single rose sells for 50 cents, so buying two will cost $1 (50 cents multiplied by 2).
With 2 roses per dollar, spending $20 allows for the purchase of 40 roses.
They make $6 profit on $20 sales, which means they spend $14 on the 40 roses ($20 minus $6).
Dividing $14 by 40 roses gives a cost of $0.35 per rose.
Therefore, the vendor pays 35 cents for each rose.
The least number of times that two planes can cross is zero, since parallel planes do not intersect. A good example would be a floor and a ceiling, which run parallel, hence they do not meet. Conversely, if two planes occupy the same space, they can intersect at infinitely many points, as could happen with a line within that plane.
Answer:
D
Step-by-step explanation:
You should insert the provided x and y coordinates into the equations to determine which one satisfies both points.
D is valid for both:
5 = 5/4(4)
0 = 5/4(0)
Answer:
b = 5√3
b = -5√3
Step-by-step explanation:
We have
Keep in mind, the root of a function corresponds to the value of x at which the function's output is zero.
In this case
The roots of the equation are the b values for which f(b) equals zero.
Thus
For f(b)=0
Take the square root of both sides
Now simplify
and 
So we find that
b = 5√3
b = -5√3
