Which statements are true about circle Q? Select three
options.
The ratio of the measure of central angle PQR to the
measure of the entire circle is
The area of the shaded sector is 4 units.
The area of the shaded sector depends on the length of
the radius.
The area of the shaded sector depends on the area of the
circle.
The ratio of the area of the shaded sector to the area of the
circle is equal to the ratio of the length of the arc to the
area of the circle.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

the answers c

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
