<h3>What is Quadratic Equation?</h3>
A quadratic equation is a second-order polynomial equation in a single variable x, ax²+bx+c=0. with a ≠ 0 .
Given:
y= -16x²+33x+45
If the height is 30 feet.
30= -16x²+33x+45
-16x²+33x+45-30=0
-16x²+33x+15=0
16x²-33x-15=0
Solving the quadratic equation
x=-b±√b²-4ac/ 2a
x= 33 ± √2049/32
x= (33+ √2049)/32 and x=33-√2049/32
x=2.44 and -0.3833

Answer:
SSS or SAS
Step-by-step explanation:
Remark
Since the two diagonals bisect each other, you have created two sets of equal lines. If that is the case, then you could prove the equality of the triangles 2 different ways.
1) The angles at the center are vertically angles which makes them equal. Since they are equal, the triangles are congruent by SAS. Notice that the angle is between the 2 equal sides.
2) Since CD and AB are marked as being equal, the triangles are congurent by SSS.
Answer:
30
Step-by-step explanation:
WE use permutation for this question:
since the letters in SQUARE are all distinct, so：
Answer:
x = 12
y = 12√3
Step-by-step explanation:
Assuming that there is no x term, the answer is 0.
The slope is 0 because this line is a flat horizontal line.
We can write y = 3.9 as y = 0x+3.9
The equation y = 0x+3.9 is in the form y = mx+b where m = 0 is the slope.
