Answer:

4 inches

Step-by-step explanation:

The radius is the line from the center of the circle to the edge. We can assume the black line on the orange is the radius.

We want to find the diameter. The diameter is twice the radius, or

d=2r

We know the radius is 2, so we can substitute that in for r

d=2*2

Multiply

d=4

So, the diameter is 4 inches

Answer:

4 in is the diameter

Step-by-step explanation:

The radius is 2 in, it is half way across, and 2 radius is equal to one diameter.

The diameter is the entire way across the circle (crossing through the center point). In this case the diameter 4 in.

hope this helps :) pleas mark brainliest if you see fit :)

1. The amount of extension in an elastic spring varies directly as the weight hung on it. If a weight of 150 gm produces an exte
gregori [183]

Answer:

900 g

Step-by-step explanation:

let e be extension and w be weight

given e varies directly as w then the equation relating them is

e = kw ← k is the constant of variation

to find k use the condition w = 150 , e = 2.9 , then

2.9 = 150k ( divide both sides by 150 )

\frac{2.9}{150} = k , that is

k = \frac{29}{1500}

e = \frac{29}{1500} w ← equation of variation

when e = 17.4 , then

17.4 = \frac{29}{1500} w ( multiply both sides by 1500 )

26100 = 29w ( divide both sides by 29 )

900 = w

1a) Possible rational roots will be of the form
  ±{divisor of 10}/{divisor of 4}
Divisors of 10 are {1, 2, 5, 10}
Divisors of 4 are {1, 2, 4}

Then possible rational roots are
  {±1/4, ±1/2, ±1, ±5/4, ±2, ±5/2, ±5, ±10}

1b) Your answer is correct.

2) One additional root will be the conjuate of the given complex root.
  5 -3i

3) If one root is 5 -√7, another will be 5 +√7. Then your polynomial is
  P(x) = (x -(5 -√7))*(x -(5 +√7)) = (x -5)^2 -(√7)^2
  P(x) = x^2 -10x +18
