Answer:
D. 84 ft^2
Step-by-step explanation:
Formula for area of a trapezoid:
where a and b = bases and h = height
The trapezoid shown has the following dimensions
base 1 = 9ft
base 2 = 12ft
height = 8ft
Using the following information we plug in the values into the formula
Hence, the area of the trapezoid is 84ft² and your answer is D
Answer:
(c) will be perpendicular to the line y = 3x+2
Step-by-step explanation:
We have given the the equation of line as y = 3x+2
We know the equation of line as y = mx+c , here m is slope and c is intercept
On comparing with standard equation of line m = 3
We know that slope of perpendicular line is
So the slope of the line which is perpendicular to y = 3x+2 will be
Now (a) Line is given as its slope is
so it will be not perpendicular
(b) Line is given as its slope is
so it will be not perpendicular
(c) Line is given as its slope is
so it will be perpendicular to the line y = 3x+2
(d) Line is given as its slope is 3 so it will not perpendicular to the line y = 3x+2
