Answer:

a & b.    in 1 sec the object reaches a maximum height of 16 feet

c.      2 sec. the object will hit the ground

Step-by-step explanation:

h = -16t^{2} +32t.

When graphed, you would get a parabola that opens down.  The vertex is the key to the problem.  The vertex (t, h) will give you the maximum height and the time to reach that height.

So,  t = -b/2a = -32/-16(2) = 1

      h(1) = -16(1^{2}) + 32(1) = -16 + 32 = 16

Therefore, the vertex is (1, 16)

So, in 1 sec the object reaches a maximum height of 16 feet

let h = 0 for when the object hits the ground

-16t^{2} +32t = 0

-16t(t - 2) = 0

t = 0  or t = 2

After 2 sec. the object will hit the ground

Can someone please help me with this math question .
Alona [7]

No, Yes, No, Yes

using the laws of exponents

(1)

(4^{3})³ = 4^{9}

4³ × 4³ = 4^{6}

4^{9} ≠ 4^{6} → No

(2)

(3^{4})^4 = 3^{16}

3^{8} × 3^{8} = 3^{16} → Yes

(3)

18^{8} = (6 × 3 )^8 = 6^{8} × 3^{8} ≠ 6^{4} × 3^{4} → No

(4)

20^{3} = (4 × 5 )³ = 4³ × 5³ → Yes

Please simplify: 5x + 2 (x - 3) = -2 (x - 1)
zysi [14]

Answer:

x= 8/9

Step-by-step explanation:

Open everything up to get 5x+2x-6=-2x+2. Move numbers with an x to the left side and without to the right to have 5x+2x+2x=2+6. Simplify to have 9x=8. Divide by 9 which leaves you with x= 8/9
