Answer:
?
Step-by-step explanation:
A = ½(b1+b2)h
B1 and b2 are the bases
H is height
A is area
The conversion only gets tricky with the cubed labels. Keep in mind that cm^3 is cm*cm*cm, and that m^3 is m*m*m, AND that there are 100 cm in 1 meter. Here's how the conversion will look if we expand it to make it simple to understand:
. If we do all that multiplying and dividing, and all the crossing out of the labels that cancel, we get
. There you go!
The general form for a straight line is y = mx + c where m is slope and c is y-intercept.
Two lines are perpendicular when the product of their slopes = -1
Given line 3x - 7y - 14 = 0, its slope = 3/7 and y-intercept = -14/7 = -2
So a line perpendicular to the given and has the same y-intercept is
y = (-7/3) x - 2
This is a vertical line. Therefore, the slope of it is undefined
Y-intercept is (0,-0.7)
x-intercept is (-1.2,0)
