Answer:
The radius is or 2.866
Step-by-step explanation:
Given
Central angle = 120
Length of arc = 6
Required
The radius
To solve this question, we'll apply the formula of length of an arc.
The length of an arc is calculated as follows;
Where theta = central angle = 120
L = length of the arc = 6.
By substituting these values in the formula above, we have
Multiply both sides by 3
Divide both sides by
Leaving the answer in terms of , the radius is calculated as
However, if we're to solve further
Taking as 3.14
The radius is 2.866

Answer:
x = StartFraction negative 8 Over 3 EndFraction, –2
Step-by-step explanation:
3x² + 14x + 16 = 0
3x² + 6x + 8x + 16 = 0
(3x² + 6x) + (8x + 16) = 0
3x(x+2) + 8(x+2) = 0
(x+2)(3x+8) = 0
x = -2 , x = -8/3.

Take both mixed numbers (a whole number plus a fraction) and turn them into improper fractions ( a numerator (top number) bigger than the denominator (bottom number). To do this, multiply the denominator by the whole number, and add the result to the numerator.
5 5/8 will become 45/8
1 1/2 will become 3/2.
Area is length* width, so width would be Area/ length. So 45/8 is the area and 3/2 is the length. Now you have (45/8)/(3/2). To divide fractions, take the second fraction and flip the numerator and denominator, forming the reciprocal (2/3). Now multiply 45/8 and 2/3
The result is 90/24, and simplifying would get 15/4, or 3 3/4. This is the width(or length)
