It’s a triangle
s
r t

rs= 2x+10 and st= x-4

the sides are equal so equal them together then solve

2x+10=x-4
+ 4 +4
2x+14=x

you got x alone so x=2x+14

now you plug in 2x+14 in for the x in rs and st

rs= 2(2x+14)+10
4x+28+10
4x+38

st= (2x+14)-4
2x+14-4
2x-10

How many different nine player batting orders can be chosen from a baseball team of 16?

lawyer [7]

This problem is basically $_{16}P_9$

$_nP_r = \frac{n!}{(n - r)!}$

If I plug in n = 16 and r = 9

$\frac{16!}{(16-9)!} = \frac{16!}{7!} = 4151347200$

So there are 4151347200 different nine player batting orders that can be chosen from a baseball team of 16 :)

If a ball is thrown into the air with a velocity of 42 ft/s, its height (in feet) after t seconds is given by y = 42t − 16t2. Fi

Andru [333]

$\bf y=42t-16t^2\implies \left. \cfrac{dy}{dt}=42-32t \right|_{t=1}\implies 42-32\implies 10$
