Answer:
4 units squared
Step-by-step explanation:
The area of the rectangle is 9 units squared
The area of the two wedge-shaped triangles on the outside of the larger triangle is 3 units squared. The final triangle area is 2 units squared. Thus 9 - 5 = 4 units squared.
Answer:
see explanation
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (3, 1), hence
y = a(x - 3)² + 1
To find a substitute (- 2, - 4) into the equation
- 4 = a(- 2 - 3)² + 1
- 4 = 25a + 1 ( subtract 1 from both sides )
25a = - 5 ( divide both sides by 25 )
a = - 
= - 
y = - (x - 3)² + 1 ← in vertex form
The answer is (-2, -1.5, 0, 2/5, 3/4)
Answer:
34
Step-by-step explanation:
because line BC divides line DA and line AE into parts with the same ratio to each other (since BC is parallel to DE). This means that (42/21)*17 will give us the length of AB, when we do so, we get 34 as the length of AB.
