hi <3
it would be option A and option C, i believe.
hope this helps :)
Answer:
A and C are similar
Step-by-step explanation:
The sum of a triangles angles = 180
If you calculate the remaining angles, you will see that both A and C have the same angles and therefore are similar.
M is the number of minutes
5+0.09m=21.29
0.09m=16.29
m=16.29/0.09
m=181
So all you have to do is:
Subtract 16.5-13.45 which you'll end up getting 3.05
Then Add 3.05+7.293
Which your answer will be 10.343
is a quadratic function, so its graph is a parabola.
Notice that the coefficient of x is 0, this always means that the axis of symmetry is the y-axis.
That is, the vertex of the parabola is in the y-axis, so the x-coordinate of the vertex is 0.
for x=0, y=-1. So the vertex is (0, -1)
The coefficient of
is negative. This means that the parabola opens downwards, so the vertex is a maximum.
Answer: (0, -1) , maximum (none of the choices)
