Answer:
v = -1
Step-by-step explanation:
First, you will need to solve it step-by-step:
(4v − 9)(1 + v) = 0
Next, you need to simplify both sides of the equation:
4v(2) − 5v − 9 = 0
Now, factor the left side of equation:
(4v − 9)(v + 1) = 0
The last thing you need to do is to set all of the factors to equal to zero:
4v − 9 = 0 or v + 1 = 0
So, that means that you answer:
v=9/4 or in your case, v = −1

Answer:
y = -1/10x^2 -1/2
Step-by-step explanation:
The equation for a parabola with focus (a, b) and directrix y = d is ...
y = 1/(2(b -d))(x -a)² +(b +d)/2
__
For the given focus and directrix, we have ...
- a = 0
- b = -3
- d = 2
- y = 1/(2(-3-2))(x -0)² +(-3+2)/2
Simplified, the equation is ...
y = -1/10x² -1/2
Answer:
48 cm is the answer
Step-by-step explanation:
Using Perimeter of rectangle = 2(l+b)
=> 2(4+2)
=> 2(6)
=> 12
As 4 rectangles multiply by 4
so, 12 × 4
= 48
