Step-by-step explanation:
If the order of the cards doesn't matter:
₅₂C₅ = 52! / (5! (52−5)!)
₅₂C₅ = 2,598,960
If the order of the cards does matter:
52 × 51 × 50 × 49 × 48 = 311,875,200
200% bc it went up 2x as much as it cost before
Answer:
8.20in³
Step-by-step explanation:
Given V = πr²h
r is the radius = 1.5in
h is the height = 6in
thickness of wall of the cylinder dr = 0.04in
top and bottom thickness dh 0.07in+0.07in = 0.14in
To compute the volume, we will find the value of dV
dV = dV/dr • dr + dV/dh • dh
dV/dr = 2πrh
dV/dh = πr²
dV = 2πrh dr + πr² dh
Substituting the values into the formula
dV = 2π(1.5)(6)•(0.04) + π(1.5)²(6) • 0.14
dV = 2π (0.36)+π(1.89)
dV = 0.72π+1.89π
dV = 2.61π
dV = 2.61(3.14)
dV = 8.1954in³
Hence volume, in cubic inches, of metal in the walls and top and bottom of the can is 8.20in³ (to two dp)
#2 because it’s a Pythagorean theorem triple
Sorry I only know that one
There’s this app called Socratic that you can use. It’s like this one but it’s a little different
