Answer:
12.62 m
Step-by-step explanation:
Area of a circle = πr²
Area = 125m²
Hence:
125m² = πr²
r² = 125m²/π
r = √125m²/π
Hence,
r =√ 39.788735773
r = 6.3078313051 m
Diameter = Radius × 2
Therefore, Diameter of one circle is
= 6.3078313051 m × 2
= 12.61566261m
Approximately = 12.62 m
(2B +5A)/7 = (2(-2, -12) +5(-9, 2))/7 = (-4-45, -24+10)/7 = (-7, -2)
Selection B is appropriate.
Answer: both the left and right sides go to +∞
<u>Step-by-step explanation:</u>
End behavior can be determined by two things:
- Sign of the leading coefficient
- Degree of the function
<u>Sign of leading coefficient</u>:
positive: right side goes to +∞
negative: right side goes to -∞
⇒ Leading coefficient of this function is 3 so the right side goes to +∞
<u>Degree (exponent of leading coefficient)</u>:
even: both the left and right sides point in the SAME direction
odd: the left and right sides point in OPPOSITE directions
⇒ Degree of this function is 4 so the left side will point in the same direction as the right side.
