Answer:

150

Step-by-step explanation:

t = sqrt((4π^2mr)/F)

Plug in the given values.

12 = sqrt((4(3.14^2)(84.4)(6.5))/F)

Solve for F.

12 = sqrt(21635.90624/F)

144 = 21635.90624/F

F = 150.249

Could someone help me do this.
Tema [17]

Answer:

Step-by-step explanation:

You have to assume that P is the center of the circle. Without that fact, there is no answer.

Both PT and PB are radii. Therefore the triangle containing <PTB and <PBT is isosceles. What that means is that angle PTB = angle PBT

So angle PBT is the answer.

ziro4ka [17]
The z-score is given by:
z=(x-μ)/σ
but
x-μ=52
thus
z=52/√84681
z=0.1787
Thus:
P(X≤52)=0.9633

According to the rational root theorem, which is a factor of the polynomial f(x)=3x^3-5x^2-12x+20?
MakcuM [25]

Answer:

(x-2), (x+2), (3x-5)

Step-by-step explanation:

Factors of 3: ±1, ±3

Factors of 20: ±1, ±2, ±4, ±5, ±10, ±20

Possible factors of the polynomial: ±1, ±2, ±3, ±4, ±5, ±10, ±20, .... (there's a lot more but you probably do not need to list them all)

Pick a number to divide the polynomial by (I picked 2)

(3x³-5x²-12x+20)÷(x-2) = 3x²+x-10

So (x-2) is a factor of f(x) = 3x³-5x²-12x+20

Factor 3x²+x-10 = (3x-5)(x-2) these are the other factors of f(x) = 3x³-5x²-12x+20
