Answer:
Step-by-step explanation:
I'll get you the answer. You pick it from what you are given.
The slope of the perpendicular is m1 * m2 = - 1
m1 = 3
m2 = -1 / m1
m2 = -1 / 3
So far what you have is
y = (-1/3) x + b
Use the point go get b
x = -1
y = - 3
y = (-1/3) *x + b
-3 = (-1/3)*-1 + b
-3 = 1/3 + b
-3 - 1/3 = b
b = -3.33333 or
b = -3 1/3
b = -10/3
So the answer is
y = (- 1/3) x - 10/3 or
y = (-1 / 3)x - 3.3333 or
y = (-1/3 )x - (3 1/3)
The solution of the given expression will be

What is the median of the data below?<br><br>
45, 19, 23, 67, 28, 35, 46, 21, 58, 60, 23, 51

To find the median, you will need to list the data from least to greatest and find the middle number.
19, 21, 23, 23, 28, 35, 45, 46, 51, 58, 60, 67
Cross out a number on both sides until you reach the middle number. In this case, we are left with 2 numbers that are in the middle since there is an even amount of numbers.
When you reach the time where you have two middle numbers, we have to find the average of those two numbers. Our two middle numbers are 35 and 45. Since we have to find the average of those two numbers, we can add them. (35 + 45 = 80). Now, since we have two middle numbers, we have to divide them by 2.

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.
Just divide 48 by 8 to give 6.
