A large explosion causes wood and metal debris to rise vertically into the air with an initial velocity of 96 feet per second. T
Vladimir [108]

Answer:

the height after 2 seconds will be 128 feet

Step-by-step explanation:

Data provided in the question:

Initial velocity = 96 feet per second

The function of height of falling debris above the ground is given as:

h(t) = 96t - 16t²

A) To find height after time t = 2 seconds

substituting the value of time in the above function, we get

h(t) = 96 × 2 - 16 × 2²

or

h(t) = 192 - 16 × 4

or

h(t) = 192 - 64

or

h(t) = 128 feet

Hence,

the height after 2 seconds will be 128 feet

The expression  is  f (x) = \frac{x}{3} - 6

Step-by-step explanation:

<u><em> Step(i):-</em></u>

Given variable start with 'x'

The variable 'x' is divided by '3'  so  \frac{x}{3}

<u><em>Step(ii):</em></u>-

The variable 'x' is divided by '3'  so  \frac{x}{3}    and after that subtract '6'

Then the expression

Developing it says constructing equations from a table
12345 [234]
The equation is y=2x+1.
to find b in y=mx+b you simply look for a point where x=0 which was (0,1) making the y-intercept or "b" equal to 1. to find the "m" or slope plug in any point for x and y. (9)=m(4)+1 is 2=m. so y=2x+1 is your answer.
