H(t) = -16t^2 + 40t +120

stira [4]

Answer:

h(t) = -16t^2 + 40t + 120

h(t) = -16(t^2 - 5/2*t) + 120

h(t) = -16(t^2 - 5/2*t + (5/4)^2 - (5/4)^2) + 120

h(t) = -16(t^2 - 5/2*t + (5/4)^2 - 25/16) + 120

h(t) = -16(t^2 - 5/2*t + (5/4)^2) + 120 + 25

h(t) = -16(t - 5/4)^2 + 145

Given: AC is a diameter of circle O and the measure of angle BAC =27. Find the

dalvyx [7]

Answer:

$m\angle BOC=54^\circ$

Step-by-step explanation:

First, we establish the following:

B, A and C are on the circle
AC is a diameter
The center of the circle is O

Therefore:

$\angle BAC$ is the angle subtended by arc BC on the circumference.\\\angle BOC$ is the angle subtended by arc BC at the centre.$

The inscribed angle theorem states that an angle inscribed in a circle is half of the central angle that subtends the same arc on the circle.

Therefore:

$\angle BOC =2\angle BAC\\\angle BOC=2 \times 27\\m\angle BOC=54^\circ$
