28.2/9.4= 3
g=3
Just divide like normal.
The gradient of this line is 9 so the gradient of the perpendicular line is -1/9 (the two perpendicular gradients must multiply to get -1).
The equation of a line is y=mx+c
where m is the gradient and c is the y intercept
We can then just substitute values in:
y = -1/9(x) -2
The formula for the volume of a pyramid is (1/3)area of the base x height.
And the questions gives us all the information we need! All we need to do is plug in the values.
V = 1/3 b x h
V = 1/3 x 625 x 30
V = 10 x 625
V = 6250 cubic meters
Hope this helps!
Answer:
Step-by-step explanation:
h(-1) = - 3|3(-1) - 6| - 3
h(-1) = - 3|-3 - 6| - 3
h(-1) = - 3|-9| - 3
h(-1) = - 3(9) - 3
h(-1) = - 27 - 3
h(-1) = - 30
