Step-by-step explanation:
The height of the object after t seconds is given by:

When will the object hit the ground?
It hits the ground after t seconds, and t is found when
. So







3 seconds, so the correct answer is given by option a.
Answer:

Step-by-step explanation:
<u><em>The correct question is</em></u>
what is the equation for a line passing through (-2,3) and perpendicular to y= -1/2<em>x</em>+1 ?
Remember
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes are equal to -1)
The slope of the given line is m=-1/2
so
the opposite reciprocal is m=2
<em>Find the equation of the line in point slope form</em>

we have

substitute

<em>Convert to slope intercept form</em>

isolate the variable y



What are you asking? If it’s true or false it’s TRUE?
Answer:
No
Step-by-step explanation:
The upper Quartile is also known as the third quartile. And the greatest value is at the far right of the plot I placed an image below
Hello!
The range is the lowest number subtracted from the highest number
The lowest number is 1
The highest number is 9
9 - 1 = 8
The range is 8

To find the median you look at the line that separates the box plot into two sections
The median is 4
Hope this helps!
