Answer:
What's the question?
Step-by-step explanation:
Answer:
Center is at (0,0)
Step-by-step explanation:
An equation of ellipse in standard form is:
Where center is at point (h,k)
From the equation of 
. First, we add 45 both sides:
Convert into the standard form with RHS (Right-Hand Side) equal to 1 by dividing both sides by 45:
Therefore, the center of ellipse is at (0,0) since there are no values of h and k.
Answer:
Option a.
Step-by-step explanation:
In the given triangle angle A is a right angle so triangle ABC is a right angled triangle.
Opposite side of right angle is hypotenuse. So, CB is hypotenuse.
From figure it is clear that CA is shorter that segment BA.
All angles are congruent to itself. So angle C is congruent to itself.
We know that, if an altitude is drawn from the right angle vertex in a right angle triangle it divide the triangle in two right angle triangles, then given triangle is similar to both new triangles.
So, triangle ABC is similar to triangle DBA if segment AD is an altitude of triangle ABC.
Therefore, the correct option is a.
Answer:
You need to buy 5 bags of flour
Step-by-step explanation:
Each bag is 500g and needs 2.5kg.
If we replace 2.5kg it goes to 2500g.
2500g / 500g = 5 bags
Answer: 42 and 54
