Mathematics

Answer:

  0.5 < t < 2

Step-by-step explanation:

The function reaches its maximum height at ...

  t = -b/(2a) = -16/(2(-16)) = 1/2 . . . . . . where a=-16, b=16, c=32 are the coefficients of f(t)

The function can be factored to find the zeros.

  f(t) = -16(t^2 -1 -2) = -16(t -2)(t +1)

The factors are zero for ...

  x = -1 and x = +2

The ball is falling from its maximum height during the period (0.5, 2), so that is a reasonable domain if you're only interested in the period when the ball is falling.

Answer:

Radius: 8

Circumference: 50.27

πr^2 = Area of circle

201.06 = πr^2

divide by pi

201.06 / π = 63.9993857161 = 64

64 = r^2

Square root both sides to get radius.

\sqrt{64} = 8

r = 8

Circumference = π x diameter

Diameter = 2 x radius

Circumference = π x 16 = 50.2654824574 = 50.27

Work out the answers to:<br>a) 7 + (-4)<br>b) (-6) + (-3)<br>c) 2 -(-6)<br>d) (-8) - (-13)​
frosja888 [35]

Answer:

a) 7 + (-4) = 3

b) (-6) + (-3) = -9

c) 2 -(-6) = 8

d) (-8) - (-13) = 5

Step-by-step explanation:

a) 7 + (-4)

= 7 + (-4)

= 3

b) (-6) + (-3)

= -6 - 3

= -9

c) 2 - (-6)

= 2 + 6

= 8

d) (-8) - (-13)

= -8 + 13

= 5
