Answer:

IIf it takes 8 seconds to move 2 feet, then it takes 4 seconds to move 1 foot

She is already 20 feet below sea level meaning she only needs 30 more feet to reach 50 ft below sea level.

tto figure out the amount of time it will take her to descend 30ft you multiply 30(distance) x 4(time)

tthe answer is 120

Step-by-step explanation:

cow->chicken is 16

chicken->horse is 21

horse->pig is 7

pig->cow is 13

16+21+7+13=57

I  know the distances from each animal to the other. I was asked to find the perimeter, because the distances of the paths create a quadrilateral.

What is the vertex , x coordinates , and x intercepts of y=2x ^2 + 4x-30
Evgesh-ka [11]
<span>5.1 </span>     Find the Vertex of   <span>y = x2-2x-15

</span>Parabolas have a highest or a lowest point called the Vertex .   Our parabola opens up and accordingly has a lowest point (AKA absolute minimum) .   We know this even before plotting  "y"  because the coefficient of the first term, 1 , is positive (greater than zero).<span> 

 </span>Each parabola has a vertical line of symmetry that passes through its vertex. Because of this symmetry, the line of symmetry would, for example, pass through the midpoint of the two  x -intercepts (roots or solutions) of the parabola. That is, if the parabola has indeed two real solutions.<span> 

 </span>Parabolas can model many real life situations, such as the height above ground, of an object thrown upward, after some period of time. The vertex of the parabola can provide us with information, such as the maximum height that object, thrown upwards, can reach. For this reason we want to be able to find the coordinates of the vertex.<span> 

 </span>For any parabola,<span>Ax2+Bx+C,</span>the  x -coordinate of the vertex is given by  -B/(2A) . In our case the  x  coordinate is   1.0000 <span> 

 </span>Plugging into the parabola formula   1.0000  for  x  we can calculate the  y -coordinate :<span> 
 </span><span> y = 1.0 * 1.00 * 1.00 - 2.0 * 1.00 - 15.0
</span> or <span>   y = -16.000</span>
