Answer:

$t = 4$ : Arrow hits the ground after 4 seconds.

Step-by-step explanation:

I assume you are going to ask when the arrow hits the ground, right? If so, follow these steps!

$64t-16t^2=0$

We can factor/distribute to solve this...

$16t(4-t)=0$

If this is true, then that means that...

$16t=0$ $or$ $4-t=0$

$t=0$ $or$ $-t=-4$

So the solution would be

$t = 0$ $or$ $t=4$

In this case, we want to use 4.

ddd [48]

Answer:

George can feed 6 people.

Step-by-step explanation:

Given:

Number of sandwiches = 4

Each person eats two-third of a sandwich.

Therefore, number of persons eating 4 sandwich is given as:

$\textrm{Number of persons} =\frac{\textrm{Total sandwiches eaten}}{\textrm{Total sandwiches eaten by 1 person}}$

Therefore,

$\textrm{Number of persons} = \frac{4}{\frac{2}{3}}\\\\\textrm{Number of persons} =4\times \frac{3}{2}=6$

What is 1/144 as an expression using a negative exponent

MrRissso [65]

ANSWER

${12}^{ - 2}$

EXPLANATION

The given expression is

$\frac{1}{144}$

This is the same as:

$\frac{1}{12 \times 12}$

In index notation, we write this as

$\frac{1}{ {12}^{2} }$

To write this as a negative index, we use the property:

$\frac{1}{ {a}^{m} } = {a}^{- m}$

This implies that;

$\frac{1}{ {12}^{2} } = {12}^{ - 2}$
