.20 I think
Because there is five divided equally
Answer:
Ф = the measure of ∠BAC in radians
Step-by-step explanation:
∵ ∠BAC is a central angle
∴ The are of the sector will depended on the length of the radius <em>r </em>and the measure of the central angle <em>Ф</em>
If the measure of Ф in degrees
∴ The area of the sector = Ф°/360° (π r²)
If the measure of Ф in radians
∴ The area of the sector = 1/2 r² Ф
When to change from degree to radian you do that
Ф radian = Ф°/180 × π
∴ Ф/360 π r² = 1/2 <u>(Ф/180 π)</u> r² ⇒ ∵ underline is Ф radian
∴ Area sector = 1/2 r² Ф ⇒ Ф in radians
For this case the amplitude is given by:
A = (l-1l + 3) / 2
A = 4/2
A = 2
The middle line is given by:
y = 1
The period of the function is given by:
T = l x2 - x1 l
T = l 0 - 2pi l
T = l - 2pi l
T = 2pi
Answer:
Amplitude: 2; period: 2π; midline: y = 1
