I would use addition
Step-by-step explanation:
Since addition is the opposite of subtraction.
Answer:
1215.916
Step-by-step explanation:
Answer:
438.97 cm²
Step-by-step explanation:
To find the surface area, we break up the figure into two pieces(blue and yellow) and then add them together.
SA = 2(w · l + h · l + h · w)
2 · (6 · 16 + 4 · 16 + 4 · 6)
368 cm²
70.97 cm² + 368 cm²
438.97 cm²
The vertex is exactly half way between directrix and focus. In this case the vertex is (8,-7)
(h,k)
P is the distance between the vertex and either the directrix or focus, in this case p = 1.
a = 1/(4p) or 1/(4*1) or 1/4
write the equation in vertex form
y = a(x-h)^2 + k
y = 1/4(x-8)^2 -7
The equation of a line of the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
If two lines are parallel then their slopes are equal.
We have the following line:
Thus, the slope of the line is -5.
Therefore a parallel line is of the form:
We replace the point
Finally, the equation is of the form:
