Question 7 Circle is shown
Z
Which statement explains why LA is a right angle?
А
B
ZA is a central angle that intercepts Y Z. Because the measure of Y Z is 180° it follows that m_A = (180°) = 90°
ZA is a central angle on diameter Y Z. Because the measure of AY Z A is 180°. it follows that m_A = { (180°) = 90°
ZA is an inscribed angle that intercepts Y Z. Because the measure of Y Z is 180°. t follows that m_A = {(180°) = 90°
LA is an inscribed angle on diameter Y Z. Because the measure of AY ZAis 180°, at follows that m_A = {(180°) = 90°
D

What are correct trigonometric ratios that could be used to determine the length of ln

The position of a moving particle is given by the position function: f(t)=-9t-t^2-0.2t^3+0.1t^4 0 a. at what time does the particle reverse direction? b. when is the displacement positive? (round one decimal place and answer in interval notation) c. when is the displacement negative? (round one decimal place and answer in interval notation) d. when is the particle’s acceleration positive? (round one decimal place and answer in interval notation) e. when is the particle’s acceleration negative? (round one decimal place and answer in interval notation)

Given that y varies directly to the square root of (x + 1), and that y = 1 when x = 8,(a)express y in terms of .x,(b)find the value of y when x = 3,(c)find the value of x when y = 5.
