Answer:
Ratio of area of triangles MNP and ABC is 1.05
Step-by-step explanation:
There are 2 triangles ABC and MNP.
We are given that ,m∠A = m∠M.
AB = 16 and AC = 10.
MN = 7 and MP = 24.
Area of a triangle ∝ Product of any two sides.
So area of triangle ABC ∝ 16
Area of triangle ABC = 160 ,
where k is a constant.
So area of triangle MNP ∝ 7
Area of triangle MNP = 168
So ratio of area of triangles =
=
= 1.05
Answer:
B, 21
Step-by-step explanation:
78 minus 57 is 21, thus B is the correct choice
ANSWER
Focus:
Directrix:
EXPLANATION
The given parabola has equation:
We compare this to the general equation,
Comparing the coefficient of x, we have:
-4p=-1
The focus is (-p,0)
The equation of the directrix is
x=p
I think the factors are 3 and 4. but if you want to be complex it might be 3, 4r, and y
