Answer:
the set of all real numbers
Step-by-step explanation:
f(x) = 3X + 9 is a polynomial, and so both the domain and the range are "the set of all real numbers."
None of your answer choices match this. Check with your teacher if you can.
Answer:
x ≤ 3
Step-by-step explanation:

One third of 75 would be 25 because you divide 75÷3=25
Answer:
15.0
Step-by-step explanation:
Let's start by looking at triangle ORQ. Since RQ is tangent to the circle, we know that angle ∠ORQ is 90°. Then, since OR is equivalent to the radius of 5, RQ is 5√3, and side OQ is clearly larger than RQ, we can identify this as a 90-60-30 degree triangle. This makes side OQ have a length of 10, and angle ∠QOR, opposite of the second largest side, has the second largest angle of 60°, leaving ∠OQR with an angle of 30°.
The formula for the chord length is 2r*sin(c/2), with c being the angle between the two points on the circle (in this case, ∠QOR=∠NOR).. Our radius is 5, so the length of chord NR is 2*5*sin(60/2)=5, making our answer 5(ON)+5(OR)+5(RN)
Answer:
<u>0.12, 6/50</u> are the answers.
Step-by-step explanation:
1/5 = 0.2
1.2/10 = 0.12
0.12 = 6/50
Have a nice day!
