You throw a baseball upward with an initial velocity of 35 feet per second. The height h (in feet) of the baseball relative to y

Nostrana [21]

Answer:

35/16 sec ( 2 3/16 sec)

Step-by-step explanation:

This assumes you glove is at height = 0

0 = -16t^2 + 35t

0 = t ( -16t + 35) shows t = 0 ( before you throw it) and t = 35/16 sec

If A = (0, 0) and B = (6, 3) what is the length of overline AB ?

Kaylis [27]

Answer:

A= (0,0) and B = (6,3)

We can find the length AB with the following formula:

$d = \sqrt{(x_B -x_A)^2 +(y_B -y_A)^2}$

And replacing we got:

$d = \sqrt{(6-0)^2 +(3-0)^2} = \sqrt{45}= 3\sqrt{5}$

So then the length AB would be $3\sqrt{5}$

Step-by-step explanation:

For this case we have the following two points:

A= (0,0) and B = (6,3)

We can find the length AB with the following formula:

$d = \sqrt{(x_B -x_A)^2 +(y_B -y_A)^2}$

And replacing we got:

$d = \sqrt{(6-0)^2 +(3-0)^2} = \sqrt{45}= 3\sqrt{5}$

So then the length AB would be $3\sqrt{5}$

What are the imaginary zeros?

Hunter-Best [27]

Answer:

A pure imaginary number can be written in bi form where b is a non-zero real number and i is the imaginary i. ... When this occurs, the equation has no roots (zeros) in the set of real numbers. The roots belong to the set of complex numbers, and will be called "complex roots" (or "imaginary roots").

A patio in the shape of a rectangle , is fenced on all sides with 134 feet of fencing. The patio is 5 feet less wide than it is

zvonat [6]

<span>P = 2l + 2w
The given values fit the given formula</span>
The given values are 134
Let L = 5 - w
Solution:
P = 2l + 2w
134 = 2(5-w) + 2w 134 = 10-2w + 2w 134 – 10 = 4w 124 = 4w
31 = w
<span>26 = l</span>
