mark as brainliest!!!! A flare was launched straight up from the ground with an initial velocity of 176ft/s and returned to the

ground after 11 s. The height of the flare t seconds after launch is modeled by the function f(t)=−16t2+176t . What is the maximum height of the flare, in feet?

I think 484 is the answer because, 0=t(-16t+176)  x=0 and  x=11.To get the add up the x intercepts and divide by 2 you should get that x=5.5.

Which of the following is being constructed in the image.
Sliva [168]

Answer:

  3. a line perpendicular to a given line through a point not on the line

Step-by-step explanation:

The point not on the line suggests that choices 1 and 3 are possibilities. The fact that the dotted line is not parallel (and is perpendicular) to the solid line suggests that choice 3 is applicable and choice 1 is not.

The short arcs are equidistant from the end points of the chord that intercepts the larger arc. Hence the line through the crossing point of the short arcs and the point on the other side of the line will be the perpendicular bisector of the chord, and will be perpendicular to the solid line. Creating that perpendicular is likely the purpose of the construction.

Write the equation of the line that passes through the points (2,0) and (1,-2)
Darya [45]

Answer:

y

=

Explanation:

First, we need to determine the slope of the line. The formula for determining the slope of a line is:

m

=

y

where

m

is the slope and the x and y terms are for the points:

(

,

y

)

and

(

Now, selecting one of the points we can use the point slope formula to find the equation.

The point slope formula is:
