Answer:
Step-by-step explanation:
x=rcosθ=4 cos (-40)=4 cos 40≈3.064
y=r sin θ=4 sin (-40)=-4 sin 40≈-2.571
the vector is (3.064,-2.571)
Y = -1
It is an isosceles trapezoid, which is just as well, otherwise it could not reflect onto itself. The line of reflection is the same as the mirror line which is the same as the axis of symmetry.
It runs horizontally exactly through the middle of the shape.
All horizontal lines have the equation y = a value
In this case the line is <span>y=−<span>1</span></span>

Answer:1897
Step-by-step explanation:
add 74,877 to 21,243 then add 39,643 to get 1897
Mean: 9.75.
Median: 2.5.To find the mean.
Count the number of data points in your data set.
Sum up the total of your data set; add them all together.
Average = Mean = Sum/Number.The median of a data set can be found by arranging all the values from lowest to highest value and picking the one in the middle.
