Answer:

You are now 38 m below base camp.

Step-by-step explanation:

Consider the provided information.

You start hiking at an elevation that is 80 meters below base camp.

Now your initial location is 80 m below base camp, that can be represents as: -80

Now you increase your elevation by 42.

So you go up by 42.

In other words, you get the equation -80+42 = -38.

Since, a negative value is below the base camp, this means that you are now 38 m below base camp.

What is the answer?​
Mrrafil [7]

Answer:

53°

Step-by-step explanation:

The angle that measures 143 is vertical to the right angle and the ? angle.

Vertical angles have the same measure. <? + <90 = <143

So do 143 - 90 = 53

So the ? angle = 53

Hope this helps ya!!

The correct answer is D. Graph D

Find the Vertex of   <span>y = 3x2+7x+2

</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) .   <span>We know this even before plotting </span> "y" <span> because the coefficient of the first term,</span> 3 , is positive (greater than zero).<span> 

 </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 </span> 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><span>the </span> x <span>-coordinate of the vertex is given by </span> -B/(2A) <span>. In our case the </span> x <span> coordinate is </span> -1.1667 <span> 

 </span><span>Plugging into the parabola formula </span> -1.1667 <span> for </span> x <span> we can calculate the </span> y -coordinate :<span> 
 </span><span> y = 3.0 * -1.17 * -1.17 + 7.0 * -1.17 + 2.0 
</span><span>or </span><span>  y = -2.083
</span>Parabola, Graphing Vertex and X-Intercepts :

Root plot for : <span> y = 3x2+7x+2</span>
Axis of Symmetry (dashed)  {x}={-1.17} 
Vertex at  {x,y} = {-1.17,-2.08}  
 x -Intercepts (Roots) :
Root 1 at  {x,y} = {-2.00, 0.00} 
Root 2 at<span>  {x,y} = {-0.33, 0.00} </span>
