Answer:
20
Step-by-step explanation:
F (-7) = -6x -22
F (-7) = -6 (-7) - 22
F (-7) = 42- 22
F (-7) = 20
hope that helps
Answer:
30°
Step-by-step explanation:
As the chord has same length of radius, the chord and the two radius form a equilateral triangle. Each angle of triangle is 60.So the chord subtended at the center is 60. So the angle subtended at the remaining part of the circle = 30°
The measure of angle between the tangent and chord = 30 {Alternate segment theorem}
F(x)= ∫[√x, 1] (2t - 1)/(t + 2) dt for x ≥ 0
<span>Let f(x) = ∫(2t - 1)/(t + 2) dt = ∫[2 + -5/(t + 2)] dt = 2t - 5Ln(t + 2) + constant </span>
<span>F(x) = f(1) - f(√x) = 2 – 5Ln(3) - (2√x - 4Ln(√x + 2) </span>
<span>F(1) = 2 - 5Ln(3) - (2√1 - 5Ln(√1 + 2) = 2 - 5Ln(3) - (2 - 5Ln(3)) = 0
