An object is dropped from a bridge and allowed to freefall to the ground. The height of the object over time can be modeled usin
kkurt [141]

Answer:

<em>t = 3 seconds</em>

Step-by-step explanation:

We have the equation, as a function of time, that describes the height of the object that is dropped from the bridge.

The equation is:

h (t) = 144 - 16t ^ 2

Where t is the time in seconds and h is the height in feet.

To know how long it takes the object to fall to the ground we do h (t) = 0 and solve for t.

So:

0 = 144 - 16t ^ 2\\\\16t ^ 2 = 144\\\\t ^ 2 = \frac{144}{16}\\\\t ^ 2 = 9\\\\t_1 = 3\\t_2 = -3

We take the positive solution.

Therefore the object takes 3 seconds to reach the ground

If a study determines the difference in average salary for subpopulations of mechanical engineers and civil engineers is NOT sig
uysha [10]

Both are not earning different salaries.

If a study determines the difference in average salary for subpopulations of mechanical engineers and civil engineers is NOT significant, then the subpopulations of mechanical and civil engineers are not earning different salaries.
Study determines that there is not any significant study so thats why both are not earning.

what is the explicit formula and recursive formula of the numbers 4,7,10,13,16...i don't even know how to start this problem. i
Lana71 [14]

An arithmetic sequence is a sequence with a constant

<span> increase or decrease also known as the </span>constant difference

In the sequence 10, 40, 70, 100, ….

The constant difference between the terms is 30

A recursive formula for a sequence would be:

a1= first term in the sequence

an = term you are trying to find

an-1 = previous term in the sequence

d = constant difference

Explicit Formulas: 

A formula that allows you to find the nth term of the sequence by substituting known values in the expression.

Formula : an = a1 + d( n - 1)

a1= first term in the sequence

an = current term in the sequence

d = constant difference

n = term number

Solution: 

<span>Write the explicit formula of the sequence 4, 7, 10, 13, 16 ….</span>

Formula for explicit term:

an = ___ + ___( n - 1)

Simplify: an = ___ + ___n

In the sequence 4, 7, 10, 13, ….

To find the 11th<span> term explicitly, I plug in the into the formula I just made:  </span>

an = 1 + 3n

a11<span> = 1 + 3(11)  </span> 

a11<span> = 34  </span>

Find the 15th term of the sequence using the formula: an = 1 + 3n

Write the recursive formula of the sequence 4, 7, 10, 13, ….

Recursive formula:

a1 =

an = a  n  - 1

In the sequence 4, 7, 10, 13, 16 ….

To find the 5th<span> term recursively, I plug it into the formula I just made:  </span>

<span>  a</span>n = an-1 + 3

a5 = a5-1<span> + 3   in words: 5</span>th<span>  term equals the 4</span>th term plus 3

a5<span> = 13 + 3  </span>

a5<span> = 16   </span>
