A baseball is "popped" straight up by a batter with an initial velocity of 32 ft/sec. The height of the ball above ground is giv

en by a function where t is time in seconds after the ball leaves the bat and h(t) is the height in feet above the ground. The batter hit the ball at an original height of 4 feet off of the ground, and the acceleration due to gravity is -16ft/se2

Answer:

The ball reaches the maximum height after 1 seconds

Step-by-step explanation:

Given

y = -16t^2 + 32t + 4 --- the function missing from the question

Required

Time to reach maximum height

The time (t) to reach maximum height is calculated using:

t = -\frac{b}{2a}

Where

y =at^2 + bx + c

So, by comparison:

a = -16

b = 32

c = 4

So, we have:

t = -\frac{b}{2a}

t = -\frac{32}{2*-16}

t = -\frac{32}{-32}

t = \frac{32}{32}

t = 1

What is the answer h+6\5=2
nexus9112 [7]

Answer:

h = 4/5

Step-by-step explanation:

h + (6/5) = 2

h = 2 - (6/5)

h = (10/5) - (6/5)

h = (10-6)/5

h = 4/5

Check:

(4/5) + (6/5) = 2

10/5 = 2

The graphs below have the same shape. What is the equation of the graph of g(x)?
maw [93]

Answer:

A

Step-by-step explanation:

Given f(x) then f(x + a) is a horizontal translation of f(x)

• If a > 0 then a shift to the left of a units

• If a < 0 then a shift to the right of a units

Here g(x) is the graph of f(x) = x²  shifted 4 units to the left, hence

g(x) = (x + 4)² → A

Answer:

  2.  x ≈ 17.74

  3.  x ≈ 16.64

Step-by-step explanation:

The tangent function relates an angle to the opposite and adjacent sides of a right triangle:

  Tan = Opposite/Adjacent

Here, we're looking for the measure of the side opposite the angle, so we can rearrange this relation to ...

  Opposite = Adjacent×Tan

__

2.  x = 32×tan(29°) ≈ 17.74

3.  x = 13×tan(52°) ≈ 16.64

_____

Hopefully, we've given enough decimal places so that you can round to the precision you need.
