A regulation basketball has a 19 cm diameter and may be approximated as a thin spherical

shell.

How long will it take a basketball starting

from rest to roll without slipping 4.0 m down

an incline that makes an angle of 45.4" with

the horizontal? The acceleration of gravity is

9.81 m/s.

Answer in units of s.

1.27 sec

Step-by-step explanation:

From the given information:

For the ball, Moment of inertia

When the height h of the ball is:

h =  4.0 sin 45.4°

and the initial potential energy = mgh

⇒ mg(4.0 sin 45.4°)

According to the conservation of energy.

∴

v = 6.32 m/s

t = 1.27  sec

i think it's either c or d

step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose c.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
