The precise name of quadrilateral ABCD is a square because there are 4 sides on a square and the quadrilateral is given has 4 points such as ABCD.
but don't take my word for it is not 100% sure
and I'm so sorry if I'm wrong
Answer:
Look down!
Step-by-step explanation:
1. 1/4*1/4*1/4
2. 1/4*1/2*1/2*1/4
Step 1: convert the equation into fhe vertex form
To do you can complete squares:
y = - [x^2 + 4x + 3]
y = - [ (x + 2)^2 - 4 + 3]
y = - [ (x + 2)^2 - 1] = - (x+2)^2 + 1
Then the vertex is (-2, 1)
Now you can drasw the vertex
Step 2: Find the roots (zeros)
y = - [ (x + 2)^2 - 1] = 0
(x + 2)^2 - 1 = 0
(x+2)^2 = 1
(x+2) = (+/-) √1
x + 2 = (+/-1)
x = - 2 +/- 1
x = -1 and x = -3
Now you draw the points (-1,0) , (-3,0)
Step 3: find the interception with the y-axis.
That is y value when x = 0
y = - (0)^2 - 4(0) - 3 = -3
Then draw the point (0, -3)
Step 4: given that the coefficent of x is negative (-1) the parabola is open downward.
So, with those four points: vertex (-2,1), (-1,0), (-3,0) and (0,-3), you can sketch the function.
The answer is -5x,,,,,,,,,
Answer:
910
Step-by-step explanation:
so to find 100% ( the number)
91 x 10
910 would be the number
