The equation that offers the best approximation to this result is: $h = -16\cdot t^{2}+28\cdot t + 8$ . (Choice D)

<h3>How to find the free fall formula for a given scenario</h3>

An object experiments a free fall when it is solely accelerated by gravity on the assumption of an <em>uniform</em> acceleration. The formula is described below:

$h =h_{o} + v_{o}\cdot t + \frac{1}{2}\cdot g\cdot t^{2}$ (1)

Where:

$h_{o}$ - Initial height, in feet.
$v_{o}$ - Initial speed, in feet per second.
$t$ - Time, in seconds.
$g$ - Gravitational acceleration, in feet per square second.

If we know that $t = 2\,s$ , $h_{o} = 8\,ft$ , $h = 0\,ft$ , $g = -32.174\,\frac{ft}{s^{2}}$ , then the height formula is:

$0 = 8 +2\cdot v_{o} - \frac{1}{2}\cdot (32.174)\cdot (2)^{2}$

$0 = -56.348+2\cdot v_{o}$

$v_{o} = 28.174\,\frac{ft}{s}$

The equation that offers the best approximation to this result is: $h = -16\cdot t^{2}+28\cdot t + 8$ . (Choice D)

Need urgent help in mathematics!! Will mark brainliest!!!! PLEASE look at the photo to answer the question .....

Mila [183]

Don’t let the letter scare you, imagine this as a simple cross product!

(32 × 1) ÷ 8 = m

32 ÷ 8 = m

4 = m

There you go, the solution to this equation is that m = 4!

I really hope this helped, if there’s anything just let me know! ☻

Question 29 <br> Find the short leg<br> Plz help

Murljashka [212]

Answer:

Step-by-step explanation:

Since the triangle is right we can use the cosine ratio to find IR

cos60° = $\frac{adjacent}{hypotenuse}$ = $\frac{IR}{TR}$ = $\frac{IR}{14}$
