Answer:

12

Step-by-step explanation:

Hello!

First of all you have to understand the order of operations.

PEMDAS

Parenthesis, Exponent, Multiplication/Divison, Addition, Subtraction.

From this you can see that we first have to deal with the exponent, then multiplication, then the addition.

So we get 2+9-(-1)

The 9 is from -3^2

2+9+1

11+1

12.

Hope this helps!

A firework is launched into the air from ground level with an initial velocity of 128 ft/s. If acceleration due to gravity is –1
Hitman42 [59]

Answer:

h = 256 feet

Step-by-step explanation:

Given that,

The initial velocity of firework, v = 128 ft/s

The acceleration due to gravity is-16 ft/s².

We need to find the maximum height reached by the firework.

The equation for the firework is :

h(t) = -16t^2 + 128t

To find the vertex's x-coordinate, we can use  

t=\dfrac{-b}{2a}\\\\t=\dfrac{-128}{2\times (-16)}\\\\t=4\ s

Put all the values in the expression for h (t).

h(t) = -16(4)^2 + 128(4)\\\\h(t)=256\ ft

So, the maximum height reached by the firework is 256 feet.
