The distance between (-5, 3) and B(5, 3) is

1 answer:

8 0

In here, we will use the distance formula
$\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

Compute the distance between <span>(-5, 3) and (5, 3)
</span> $=\sqrt{\left(5-\left(-5\right)\right)^2+\left(3-3\right)^2}$
<span>
= 10

The distance between </span>(-5, 3) and (5, 3) is 10

Answer:

There is a correlation between age and length of stay. There may or may not be causation. Further studies would have to be done to determine this.

The height of a toy rocket that is shot in the air with an upward velocity of 48 feet per second can be modeled by the function

NikAS [45]

Answer:

maximum height reached = 35 feet

and $f(t) = 48t-16.07t^{2}$

Step-by-step explanation:

writing linear motion equations

$s = ut + \frac{1}{2}at^{2}$

where s is the total displacement, u the initial velocity, t the time travelled, and a is the acceleration.

given u = 48 ft/s, and a = acceleration due to gravity g = -9.8 $\frac{m}{s^{2}}$

1 m = 3.28 feet therefore g becomes -9.8×3.28 $\frac{ft}{s^{2}}$

here negative sigh comes as acceleration due to gravity is in opposite direction of initial velocity.

therefore f(t) becomes $f(t) = 48t-16.07t^{2}$

to find max height we should find differentiation of f(t) and equate it to 0

therefore we get 48 = 32.144t

t = 1.49 s

therefore max height f(1.49) = 71.67-36.67 = 35 feet

Which function has zeros at x=-2 and x=5?

Licemer1 [7]

Answer:

$x^{2} - 3x - 10$

Step-by-step explanation:

To start, lets form our polynomial factors from our zeroes.

x = -2

x + 2 = 0

x = 5

x - 5 = 0

Now lets put these into factored form by moving them into parenthesis and multiplying them with each other!

(x+2)(x-5)

We can start moving them out! I am going to use FOIL, but you could also use distributive or any other method/property.

x · x = x²

x · -5 = -5x

x · 2 = 2x

2 · 5 = 10

Now lets put our terms into our polynomial function, based on the order of the powers.

$x^{2} - 3x - 10$

We are done! Hope this helps!
