Answer:
1/10
Step-by-step explanation:
P( 1st out of ink) = out of ink/total
=2/5
Then we have 4 pens left, 1 out of ink
P( 2nd pen out of ink) = out of ink/total
=1/4
P(2 pens out of ink) =P( 1st out of ink) * P( 2nd pen out of ink)
= 2/5* 1/4
=1/10
Answer:
The correct answer is The equation (9−8)2+(0−6)2=(9−10)2+(0+7)2 is a true statement, so P is on ⨀C.

Answer:
cot(θ) = 4/5
Step-by-step explanation:
In the polar/rectangular coordinate representation (x, y) ⇔ (r; θ), we know that ...
(x, y) = (r·cos(θ), r·sin(θ))
From the various trig definitions and identities, we also know that ...
cot(θ) = cos(θ)/sin(θ) = (x/r)/(y/r) = x/y
For the given (x, y) = (-4, -5), the cotangent is ...
cot(θ) = -4/-5 = 4/5
It'll be easer if we write the volume of the table as a decimal - 3 3/8 is as much as 3,375. Now we just have to find the cube root of 3,375:
∛3,375 = 1,5
Doublecheck: 1,5³ = 1,5 * 1,5 * 1,5 = 3,375, so it's correct.
Answer: The length of the edge is 3,375 feet.
