Adog that has been tethered with a 20 foot lead

m∠∅ = 2.25 radians

Step-by-step explanation:

A dog has been tethered with a lead of 20 feet which makes a path making an arc of 45 feet. We have to calculate the measurement of the angle ∅ in radians.

Since the formula to measure the length of arc = r∅

where r is the radius of arc

Therefore ∅ = Arc/radius

∅ = 45 /20 = 2.25 radians

The answer is 2.25.

w'x is 0.

hope it

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
